Abstract:
A
field experiment was carried out during the winter (rabi)
season of 2013 at the Crop Research Farm, Department of Agronomy, SHIATS,
Allahabad (U. P.) to evaluate the effect of Nitrogen levels and
Intercropping with Chickpea (Cicer arietinum L.) under different row ratios on growth
and yield of Brown mustard (Brassica
species L.)”. The experiment consisted of twelve treatments
comprising of three nitrogen levels (viz.,100 % recommended dose of
nitrogen (RDN) to brown mustard + 100% RDN to chickpea, 75 % RDN to brown
mustard + 100 % RDN to chickpea, and 100 % RDN to brown mustard +75 % RDN to
chickpea) and four row ratios (viz., brown mustard : chickpea in row ratio of
1:1, 1:2, 1:4 and 1:6), which were laid out in Randomized Block Design and
replicated thrice. The experimental findings reveal the highest no. of siliqua/plant in brown mustard in treatment T7
[100% RDN Brown mustard : 100% RDN Chickpea(1:4)],
maximum no. of seeds/siliqua in treatment T8
[75% N Brown mustard: 100% N Chickpea (1:4)], maximum test weight in
treatment T7 and highest seed yield in treatment T3
[100% N Brown mustard : 75% N Chickpea (1:1)]. In chickpea the maximum no. of
pod/plant, grains/pod, seed index were recorded in treatment T7
[100% RDN Brown mustard : 100% RDN Chickpea(1:4)]
although the maximum seed yield was recorded under treatment T10
[100% RDN Brown mustard : 100% RDN Chickpea(1:6)] due to more no. of plants
in 1:6 row ratio of brown mustard : chickpea. Therefore, the highest benefit
cost ratio was recorded under treatment T10 due to more plant
population of chickpea. Key words: Brown
mustard, Chickpea, Nitrogen levels, Intercropping and Row ratios |

Abstract: The
present investigation was carried out in the research farm of College of Post
Graduate Studies, CAU, Umiam, Meghalaya,
India in 2012 to study the residual effect of green manure and phosphorus on
bio economic evaluation of baby corn and phosphorus. In summer, the
experiment was conducted for baby corn with in situ green manuring consisting of two levels i.e. without and with
green manuring and three levels of phosphorus i.e.
0, 30, 60 kg P2O5 ha-1 supplied through
single super phosphate. In kharif, residual
effect of green manuring and phosphorus levels were
studied on sole baby corn, sole groundnut and baby corn + groundnut (1:1)
intercropping system in split-split plot design with four replicates.
Residual green manure significantly influenced the nitrogen, phosphorus and
potassium uptake in baby corn while only phosphorus uptake in groundnut. With
increase in the residual phosphorus levels, the nitrogen, phosphorus and
potassium uptake increased. Yield of baby corn and groundnut in system were
5.74 and 1.35 t ha-1, respectively. Land equivalent ratio (LER) of
system was 1.35 which show that 35 % extra land is required in sole baby corn
and groundnut to compensate the yield of intercropping system. Partial LER
for baby corn was greater than groundnut showing higher competitiveness of
baby corn. Baby corn + groundnut intercropping is very productive and
remunerative with high baby corn equivalent yield (9.51 t ha-1),
Net returns (Rs. 1, 25,322) and benefit: cost ratio (3.29). Key words: Baby

Abstract: Climate
change is a major challenge facing our planet today. There is scientific
evidence that many mountain regions have become increasingly disaster-prone
in recent decades, and that a disproportionally high number of natural
disasters occur in mountain areas. Mountains are more frequently affected
than other environments by destructive natural processes including
earthquakes, volcanic eruptions, dam bursts or glacial lake outbursts, Flash
flood, Flood. Global warming reduces snow cover, melts away glaciers, and
degrades permafrost areas. The rapid release of melt water and rainfall may
combine to trigger debris flows and flash flood in higher ranges, including
the formation of potentially dangerous lakes. These lakes may breach
suddenly, resulting in discharge of huge volume of water and debris. The Kinnaur district of Himachal Pradesh had experienced a
large number of incidences of flood since its inception in 1971. Though the
state has also faced severe flood disaster in 1975 and 1988 but the last
decade (1997-2005) has proved one of the worst decades as both the magnitude
and frequency of floods have gone up. Flash flood of March 1975, Dec 1988, Satluj flash flood of August 2000, July 2001, June 2005,
Flash flood of July 2005 and Cloud burst in June 2013 are the major natural
calamities in Kinnaur. Cloudburst leads to
flashfloods, landslides, uprooting of trees, house collapse, dislocation of
traffic & bridges and human causality on large scale over the area and
brought heavy toll to the state as the loss was estimated in several thousand
millions of rupees and also killed several hundreds of people besides large
number of cattle heads. In this study we try to find out the best mitigation
solution through study of past Hydrometerological
disaster (HMD) in Satluj basin Kinnaur
district and concluded that these disaster are by their nature difficult to
predict and control but it is possible to reduce the risk to lives and
property through structural measures such as construction of dam which
provide a range of economic, environmental, and social benefits, including
recreation, flood control, water supply, hydroelectric power, waste
management, river navigation, and wildlife habitat.. Key words: Climate

Abstract:
The
study was carried out to detect and describe the outbreaks of Hog Cholera
(HC) or Classical Swine Fever (CSF) in different parts of North-Eastern
region of India by histopathological techniques in
post mortem samples. Histopathological alterations
in different lymphoid and non-lymphoid organs provides clue to confirm hog
cholera disease. Pigs died of suspected swine fever (hog cholera) virus infection
were subjected to postmortem examination and gross lesions were recorded.
Samples like kidneys, mesenteric lymph node, spleen and tonsils of
approximately 8x8cm size were collected and preserved in10% formal saline
solution. Histopathologies were done as per the
method described by Luna, 1968. From 9 outbreaks of hog cholera, 60 samples
were collected for histopathological examination.
All samples (Tonsil, Kidney, Mesenteric Lymph Node (MLN), spleen and brain)
were found positive for hog cholera on basis of gross and microscopic
findings. For detection of Hog Cholera disease, Tonsil, Kidney, Mesenteric
Lymph Node (MLN), spleen and brain were found very suitable samples. Presence
of pathogonomic changes in post mortal samples
confirms the outbreak of Hog Cholera disease. Key words: Tonsil,

Abstract: Increasing scarcity of resources (labour, water and energy) and cost of production, along
with climatic variability are major challenges for the sustainability of
wheat, the most important crop from the food security point of view in the
north-western Indo-Gangetic Plains (IGP).Based upon
the inherent potential to address the above issues in conservation
agriculture based zero tillage practice and water saving micro-irrigation
techniques in the IGP, the study was done which included five irrigation
techniques namely micro-sprinkler, drip, chapin
drip, low energy water application (LEWA) and conventional flooding and
sub-plot with tillage treatments as reduced and zero tillage along with one
control i.e.broadcast wheat under flood irrigation.
The study revealed that micro-irrigation systems saves irrigation water to a
tune of 42.5% and improves the water use efficiency by almost 60% than flood
irrigation technique. The grain yield under drip irrigation technique was
found to be 22% more than that of broadcast coupled with flood irrigation
method. The zero tillage performs better than reduced tillage under different
micro-irrigation systems. The LEWA and chapin
system still need much refinement for being applicable at the field scale. Key words:Wheat, Micro irrigation techniques, Zero

Abstract:
An
investigation was carried out during kharif
2012 at Agricultural Research Farm, Institute of Agricultural Sciences,
Banaras Hindu University, Varanasi (U.P.). All the
52 genotypes were sown in the nursery on 12th June 2012, and 25 days
old seedlings were used for transplanting in the field. All entries
were grown in a randomized block design (RBD) in three replications to
estimate correlation coefficients and path analysis for grain yield and yield
contributing traits in rice. Correlation studies in rice revealed that
genotypic correlation coefficients were higher than phenotypic correlation
coefficients for most of the characters under study. Character association
analysis revealed significantly positive association of grain yield per plant
with number of effective tiller per plant, number of tiller per plant, grain
weight per panicle, kernel L/B ratio and 1000 grain weight. Correlations
among yield components were positive, encouraging rapid improvement of yield.
Path analysis revealed that number of grains per panicle, tiller per plant,
spikelet fertility, days to maturity, 1000 grain
weight kernel length and plant height had high positive direct effects on
grain yield. Hence, selection based on these traits could help to bring
simultaneous improvement of yield and yield attributes. Key words: Correlation,

Abstract:
A
field experiment was conducted during rabi,
2010-11 and 2011-12 to study the effect of methods of sowing, nitrogen levels
and irrigation scheduling on production and quality of malt barley (Hordeum vulgare
L.). The study revealed that plant height, dry matter accumulation, effective
tillers, grains/ear, 1,000-grains weight and grain and straw yields were
statistically at par with different method of sowing. Grain, straw and malt
yields increased significantly with an increase in N level from 50 to 100% of
recommended dose as a result of increase in plant height, dry matter
accumulation, effectives tillers, grains/ear and 1,000-grains weight. The
highest grain (4.8 t/ha) and malt yield (3.98 t/ha) were obtained with 100%
of recommended N, which was statistically at par with 75% of recommended N
and significantly higher than 50% of recommended N. N, P and K uptake was
also not-significantly affected by methods of sowing, while increase in N

Abstract:
A
field experiment was conducted during kharif season
in farmers field to study the yield, economics and
nutrient uptake of aerobic rice under different intercropping systems.
Results showed that significantly higher rice grain yield was noticed in sole
aerobic rice (5470 kg ha-1) followed by rice + amaranthus
(5085 kg ha-1). Also higher yield attributing parameters like
number of productive tillers hill-1 (32.96), Number of grains
panicle-1(256.77), number of filled grains panicle-1
(235.93), less Number of chaff grains panicle-1 (20.84) were
responsible to give significantly higher grain yield of rice. Among the
different intercropping systems, rice + amaranthus
recorded significantly higher rice equivalent yield (18007 kg ha-1)
compared to sole crop of rice (5470 kg ha-1) and rice + french bean (4716 kg ha-1). However, it was
statistically on par with rice + coriander (17926 kg ha-1). Rice +
amaranthus recorded more REY than french bean (73.81 %), bhendi
(19.75 %), radish (42.87 %), soybean (55.14 %) and sole rice (69.63 %).
Higher nutrient uptake was observed in sole rice crop (170.53 kg nitrogen ha-1,
55.58 kg phosphorus ha-1 and 128.1 kg potassium ha-1)
compared to other intercrops but it was on par with amaranthus
intercrop with rice. Available favourable residual
nutrients status of NPK (311.1 44.6 and 221.5 kg ha-1) were
recorded higher in rice + soybean as compared to sole crop of rice in the
soil after harvest of the crops. With respect to economics, Rice + amaranthus recorded significantly higher gross returns
(Rs. 1,03382 ha-1), net returns (Rs.84,107
ha-1) and B C ratio (1:5.36) as compared to the other intercrops. Key words: Aerobic

Abstract:
The
screening of various trichogrammatids against Plutella xylostellareveleas that the per cent
parasitism of P. xylostella eggs by
different Trichogramma spp. ranged from a
minimum of 3.6 per cent by T. japonicum to a
maximum of 45.3 per cent by T. pretiosum (arrehenotokous), which was significantly higher than
other species tested). T. chilonis was next
superior species with 27.8% parasitism and T. achaeae
18.6% and T. evanescens 18.1% were
next best species and were on par with each other. The parasitism of P. xylostella eggs by other species was between
4.5-7.6%.The result thus indicated that T. pretiosum (arrehenotokous)
species was suitable candidate species for further experiments against P. xylostella. Against P. xylostella
on cabbage, T. pretiosum (arrehenotokous) species was used @ 50,000 and 100,000/ha,
1-3 times in a brood of the pest. The study suggested that release @ 100,000

to evaluate the effect of milk and sugar on yield of Clotted cream. Here four
type of milk (cow milk, buffalo milk, combined milk and skim milk) and three
levels of sugar (6%, 8% and 10%) were taken and replicated three times. Overall
average yield of Clotted cream was found to be 28.894 per cent. On account of
different types of milk, average yield of Clotted cream were recorded to be
29.233, 31.007, 29.969 and 25.367 per cent from cow milk, buffalo milk,
combined milk and skim milk, respectively. On account of various levels of
sugar, yield of Clotted cream were 27.043, 28.938 and 30.700 per cent at 6 %,
8% and 10% sugar level, respectively. The highest yield (32.700%) was noted
in the combination of Clotted cream which prepared by buffalo milk with 10 %
sugar level whereas lowest (23.400%) yield was found in Clotted cream which
was prepared by skim milk with 6% sugar level, but 6% sugar was preferred for
production of Clotted cream . So it was concluded
that the maximum yield can be obtained by increasing fat and total solids in
the composition for preparation of Clotted cream. The buffalo milk is
suitable for preparation and yield of Clotted cream with 6% sugar level due
to higher percentage of total solids. Key words: Milk,

Abstract:
Araiya is a water
logged area of Begusarai wetland. It is located at Kusmahaut village, 15 km
northeast of Begusarai district headquarter of
Bihar. The total water spreading area of Araiya
during monsoon is 3 to 4.5 ha. The physico-chemical
parameters play a vital role in the wetland ecosystems. The present work is
an attempt to elucidate the details of the physico-chemical
parameters of Araiya viz. water temperature (WT),
transparency of water (TW), water depth (WT), pH, dissolved oxygen (DO), free
carbon dioxide (FCO2), electrical conductivity (EC), total
hardness (TH), total alkalinity (TA), phosphate (PO43-)
and nitrate (NO3-). Present investigation shows that Araiya’s water has WT (16.3 - 33.0°C), TW (20 - 35 cm),
WD (32 - 172 cm),slight acidic to alkaline pH (6.8 - 7.4), moderate level of
DO(4.5 - 7.8 ppm), high level of FCO2 (7.5
- 12.5 ppm),moderate level of EC (120 – 180 µs),
high level of TH(96 – 147 ppm), moderate level of
TA (65 – 89 ppm), suitable range of PO43-(0.14
- 0.35 ppm) and NO3- (0.16 -
0.39 ppm). Present study will help for further
strategy for the development of mentioned wetland (chaur).
There is a fluctuation in the physico - chemical
parameters of the water. It is due to in flow of rain and agricultural water
in water body and change in the temperature as season changes. Present study
will help for further strategy for the development of wetland. Key words: Wetland,

Abstract:
A
field experiment was conducted on wheat under block plantation of 5-year old
poplars and in open field at Allahabad (U.P.) during Rabi 2011-12 and
2012-13. The treatments comprised 8 combinations of two varieties viz., PBW
343 timely sown and K9423 late sown and four fertility levels viz. F0-no
fertilizer; F1-N100P40K20 in
PBW343 and N60P30K20 in K9423; F2-N120P60K40
in PBW343 and N80P40K30 in K9423; and F3-N140P80K60
in PWB343 and N100P50K40 kg/ha in K9423. The
results revealed that wheat grown under poplar plantation reduced grain yield
by 5.18 and 8.86 q/ha or 16.0 and 27.3% while net return reduced by Rs. 7937
and 14641/ha or 29.6 and 53.9% during 2011-12 and 2012-13, respectively
compared to wheat grown in open field. The interaction effect of varieties x
fertility showed that under poplar plantation, PBW343 respond with up to F2
fertility (34.48 and 30.68 q/ha grain yield and Rs. 28446 and 21862/ha net
return) while K9423 responded only up to F1 fertility with 26.36
and 22.38 q/ha grain yield and Rs. 17183 and 10302/ha net return during
2011-12 and 2012-13, respectively. In case of sole wheat crop, PBW343
responded significantly up to F3 fertility with 47.50 and 47.60
q/ha grain yield and Rs. 47923 and 48857/ha net return, whereas K9423
responded only up to F1 level with 30.83 and 31.08 q/ha grain
yield and Rs. 24314 and 24990/ha net return during 2011-12 and 2012-13,
respectively. It may thus be concluded that for wheat cultivation under
poplar plantation variety PBW343 with N120P60K40
kg/ha fertility is most suitable for higher yield and returns. However for
late sown wheat variety K9423 with N60P30K20
fertility may be practiced. Key words: Wheat,

Abstract:
The
experiment was conducted for consecutive two years in Randomized Block Design
with three replications. In present investigation 54 genotypes (10 lines + 4
testers + 40 F1’s) of bottle gourd were grouped into nine distinct
non over lapping clusters. This indicated presence of considerable diversity
in the genotypes. The clusters contained genotypes of heterogenous
origin. The genotypes of same geographic region were also found to be grouped
together in the same clusters. Thus, there was no consistent relationship
between genetic divergence and geographical distribution. Cluster II had
maximum number of genotypes (20) followed by cluster III (13), cluster (11)
and cluster (5), while rest of the five clusters contains mono genotypes. The
intra cluster D2 values ranged from 0.00 (cluster IV, V, VI, VII
and IX) to 186.54 (cluster III), while the inter cluster D2 values
ranged from 69.86 (cluster IV and VII) to 730.23 (cluster VIII and IX).The
inter cluster distances between cluster VIII to cluster IX (730.23) and
cluster VI to cluster VIII (657.40) were also very high. The higher inter
cluster distance indicated greater genetic divergences between the genotypes
of those clusters, while lower inter cluster values between the clusters
suggested that the genotypes of the cluster were not much genetically diverse
from each other. Cluster VI showed the maximum mean values for days to first
staminate flower anthesis, days to first pistillate flower anthesis,
node number to first staminate flower, days to first fruit harvest and
ascorbic acid. Whereas, cluster IX showed maximum mean values for fruit yield
per plant and some other traits. The results suggested that crosses between
selected lines/F1’s from widely separated
clusters are most likely to give desirable hybrids/segregates. Key words: Bottle gourd, Genetic divergence, D2

Abstract:
Malnutrition
means more than feeling hungry or not having enough food to eat.
Inadequate intake of protein, calories, iron and other essential
nutrients leads to malnutrition. Poor nutrition occurs in
developing countries, as well as in more prosperous areas of the
world. About 800 million persons worldwide are affected by
malnutrition. More than half the childhood deaths in developing
countries are related to malnutrition. In this study subjects were selected
from Madurai South, Vadipatti and Melur taluks. Rural farm women
in the age between 20-40 years were selected as subjects for the study and
the total number of respondents were fixed as
ninety. A pre-tested questionnaire were used to
assess theanthropometric status and nutritional
status of the respondents. The height weight BMI and skin fold thickness of
the respondent’s ranges between 140 and 165 cm,40 and 65 kg, 13 and 25 and
14.9 and 16.5 mm. The findings of the study revealed that most of the
respondents were found to be within the normal height, weight, BMI and skin
fold thickness measurements. The number of respondents suffering from angular
stomatitis, cheliosis,
bleeding gums, dry and wrinkled eyes and goiter in Madurai district were 45,
21, 28, 22 and one respectively.The results
inferred thatthe respondents might have consumed

Abstract:
A
field experiment was conducted on wheat (triticum aestrivum) during Rabi 2009-10 and 2010-11 at
Fertilizer research Station, Uttaripura (Kanpur
Nagar) of C.S. Azad university
of Agriculture and technology,
Kanpur in rice wheat cropping system. Treatments comprised 18 combinations of
3 K-levels (0, 60, 120 kg K2O/ha) and 3-S levels (0, 40, 60 kg
S/ha) under residual effect of green leaf manuring
and without GLM residual effect. Experimental findings revealed that
increasing levels of K and S application increased growth and yield
attributes, yields and nutrient uptake with upto
120 kg K2O or 60 kg S/ha during both years. The combined
application of 120 kg K2O + 60 kg S/ha recorded maximum values of
47.85 and 43.90 q/ha grain yield, 73.92 and 78.50 q/ha straw yield, 137.94
and 128.89 kg/ha N-uptake, 30.31 and 30.01 kg/ha P-uptake, 170.34 and 167.72
kg/ha K-uptake and 15.49 and 15.21 kg/ha S-uptake of wheat crop during
2009-10 and 2010-11, respectively. Protein content in grain was also recorded
significantly highest with 120 kg K2O/ha application (12.94 and
12.69%) and with 60 kg S/ha (12.69 and 12.60%) during two years of study.
However, combined use of 120 kg K2O + 60 kg S/ha during 2009-10
and 120 kg K2O + 40 kg S/ha during 2010-11 recorded highest grain
protein content of 13.19 and 12.94%, respectively. Residual effect of green
leaf manuring was reflected only in grain yield and
that too during 2010-11 when GLM residue produced 43.19 q/ha
grain yield against 41.55 q/ha grain yield without residue of green leaf manuring applied in preceding rice crop. Key words: Wheat, potassium, sulphur, yield,

Abstract:
Ground
water recharge is the process by which water percolates down to the soil and
reaches the water table, either by natural or artificial methods. Ground
water plays a crucial role in the country in increasing food and agricultural
production, providing drinking water and facilitating industrial development.
As per the Indian Rainwater Budget, an amount of 400 Mha-m
of water through precipitation is received every year with an average
rainfall of 1194 mm on 328 Mha area.Present
study was undertaken to improve ground water table through artificial tubewell recharge under watershed development programme in Vidisha district
of Madhya Pradesh. The study reveals that recharge tube wells performed well
during the whole year without any drastic reduction in ground water level.
The rainwater harvesting through tubewell recharge
enables farmers to provide 41.6 to 81.1 % more irrigated area. Key words: Artificial groundwater recharge,

Abstract: The aim of this study was to
elucidate the effects of osmopriming with PEG 6000
on five tomato genotypes viz. Kashi Vishesh, Kashi Amrit ,
Kashi Anupam, Kashi Hemant and Kashi Sarad, under salinity
stress. Seeds were primed with varying concentration of PEG 6000 i.e.
(-0.5, -1.0, -1.5, -2.0 MPa) and along with one hydroprimed for 48 hours at 25°C. Dry tomato seeds served
as control (non-primed). Treated seeds of all varieties were sown in Petri
dishes supplied with three different concentrations of salt solution i.e.
4, 8 and 12dSm-1 and along with one control. Results of variance
analysis made clear that different osmotic potential and priming duration had
significant effect on germination percentage, vigor index and dry weight. Of
the five tomato genotypes, Kashi Hemant primed with -0.5 Mpa
showed highest per cent germination (71 %), seedling length (18 cm), seed
vigor index (994) and dry weight (14 mg)at 4 dSm -1
as compared to 8 dSm -1, 12 dSm -1 and control respectively. The results
revealed that the same variety has immense potential to tolerate salinity
stress. Furthermore, it was also observed that primed seeds exhibited better
stress tolerance than non-primed seeds.

Abstract: An experiment was conducted to the
alleviating adverse effects of soil salinity on biomass production and
physiological changes in wheat (Triticum aestivum L) through application of zinc fertilizer.
Three wheat varieties viz., KRL 19, NW 1012 (salt-tolerant) and HD 2285
(salt-susceptible) were grown in pots under two non-saline (0, 20 kg ZnSO4) and two saline (8.0 dSm-1,
20 kg ZnSO4 + 8.0 dSm-1)
environments during rabi seasons of 2001- 03. Ear
emergence stage, plant were harvested and the shoot and root were analyzed
dry matter production, chlorophyll content, proline
content, Zn concentration, and K/Na ratio. Study revealed that there was a
significant reduction in the dry matter production of root and shoot,
chlorophyll content and Zn concentration due to soil salinity whereas, K/Na
and proline content was increased in all the wheat
varieties grown in saline environments. Maximum reduction in these parameters
was recorded in the susceptible variety (HD 2285) whereas, minimum in the
salt tolerant varieties (KRL 19 and NW 1012). The K/Na ratio and proline content in leaf were significantly lower in
salt-tolerant varieties (KRL 19 and NW 1012) and higher in salt-susceptible
variety (HD 2285) under salinity. ZnSO4
application @ 20 kg ha-1 partially alleviated the adverse effects
of salinity on biomass production, chlorophyll content, proline
content, Zn concentration, and K/Na ratio in the susceptible variety HD 2285
compared to no application. Key words:Salinity, ZnSO4,

Abstract: The main experiment consisting of 22
genotypes for 17 characters was laid out in randomized block design (RBD)
with three replications at departmental main experiment station during April,
2010 to Oct., 2010. The studies revealed that there was wide
variability in arvi for various characters studied.
Analysis of variance for the design of experiment showed that the genotypes
were highly significant for all the characters under study. The high
magnitude of phenotypic and genotypic coefficient of variation was observed
for corm yield (g) and its contributing traits per plant. Corm yield per
plant, starch content, petiole length, cormel yield
per plant, sheath length, number of cormels per
plant and width of lamina exhibited high value of PCV and GCV. Length of
lamina had positive and highly significant correlation with width of lamina,
number of corm per plant, corm yield per plant, diameter of corm, diameter of
cormel and cormel yield
per plant. At phenotypic level highest positive direct effect on number of cormels per plant followed by corm yield per plant, plant
height, diameter of cormel and width of lamina and
at genotypic level highest positive direct effect on number of cormel per plant followed by number of corm per plant,
length of lamina, corm yield per plant, plant height and petiole length. The
genotype NDC-71 produced highest yield followed by NDC-76, NDC-77, NDC-69,
NDC-83 and NDC-70, NDC-71 is superior to NDC-1 for all the characters, except
sheath length, diameter of plant and cormel yield
per plant..
