Abstract: A field experiment was conducted at the Ugar
Sugar Factory premises, Ugar-Khurd, Belgaum
district to study the effect of long-term spentwash
irrigation on physical and biological properties in a Vertisol
under Northern Dry Zone (Zone-III) of Karnataka. The long-term spentwash irrigation for >20 years reduced bulk
density (1.43 to 1.22 Mg m-3), dispersion index (8.09 to 7.84) and
erosion index (4.15 to 3.93) of the surface soil. The other physical
properties like maximum water holding capacity (74.46 %), per cent water
stable aggregates (66.16) and infiltration rate (0.79 cm hr-1) was
higher in the treatment where spentwash was applied
for >20 years. Application of spentwash
increased the population of bacteria, actinomycetes
and fungi in the soil over control. The highest bacterial population (10.21 cfu x106) was noticed in treatment that
received spentwash for 5 to 10 years of surface
soil. The highest fungi population (14.56 cfu x104)
was recorded in the treatment that was irrigated with spentwash
for > 20 years. In general, bacteria, fungi and actinomycetes
population decreased with depth in all the treatments. Key wards: Bio-methanated spentwash,

Abstract: Potato is the most abundantly produced edible food in the
world, next to cereal. Potato is a wholesome food. Apart from starch of which
it is a rich source, it provides essential body-building substances such as
vitamins minerals and protein. Potato is one of the richest sources of
calories needed to main day-to-day output of human energy. The present study
was carried out in Tripura during 2013-14. A Sample of true potato seed
farmers comprising 150 respondents was selected on stratified random sampling
with proportional allocation method. The primary data was collected using
pre-tested structured interview schedule. All of the farmers used treated
seeds because tuber lets were already treated by dealers and farmers are also
aware of the benefits of treated seed. Majority 50 per cent of the
respondents had medium extent of adoption followed by high level of adoption
45 per cent and low 5 per cent level of extension. This indicates that
majority of the farmers were in medium and high level of adoption due having
good knowledge and aware of high production as compare to tradition potato
seed cultivation practices. Correlation coefficients betweenFamily
size, Education, Annual income, Operational land holding Cropping intensity
Innovation-proneness Economic motivation Risk orientation, Contact with
extension staff, Mass media exposure and Sources of information were found to
be positive and significant of personal, psychological & communication
characteristics with adoption of TPS cultivation technology of the farmers. Keywords: Extent of

Abstract: Twelvehybrids along with their seven parents were
subjected to study the genetic variability indicated that genetic material in
the present investigation possessed variability which provides sufficient
basis for selection by breeder.High estimates of
PCV and GCV were obtained for biological yield per plant and seed
yield per plant indicated a good deal of variability in those characters
signifying the effectiveness of selection of desirable types for improvement.
High heritability was observed for all the traits indicated that the
characters under study are less influenced by environment in their
expression. All the traits under study showed low genetic advance ranging
from 1.68 to 2.05. High heritability coupled with high genetic advance as
percentage of mean (GAM) were observed for straw yield per plant, seed yield
per plant and 1000 seed weight, indicating predominance of additive gene
action for these characters. Hence, simple selection based on phenotypic
performance of these characters would be more effective. Key words: Linseed, F1

Abstract: The present investigation was carried out in the segregating
population of two rice cross combinations viz., Swarna x Ranbir basmati and Swarna x BR2655. The results revealed that the
appreciable genetic variability for grain iron and zinc content along with
other biometrical traits. Moderate to high variability was observed for
grains per panicle, grain length, L/B ratio, in Cross 1 and Cross 2 for plant
height, grains per panicle, in F3 generation. Hence, these traits
need one or more generations in order to attain homozygosity.
The existence of comparatively moderate variability for these traits, which
could be exploited for improvement of the traits through selection in
advanced generations. The high genotypic and phenotypic coefficient of
variability were observed for panicle weight, grain yield kg per ha, in Cross
1(Swarna x Ranbir basmati)
and Cross 2 (Swarna x BR2655) for number of
panicles per plant, panicle weight, grain yield. It indicates high
variability among the lines. High heritability coupled with high genetic
advance as per cent of mean were recorded for plant
height, number of panicle per plant, panicle weight, number of grains per
panicle, L/B ratio, grain yield kg per ha in Cross 1(Swarna
x Ranbir basmati) and Cross 2(Swarna
x BR2655) for number of panicle per plant, panicle weight, number of grains

Abstract: In the
remote areas of the Indian Himalayan Region, the inhabitants largely depend
on medicinal plants for curing diseases and income generation. But, proper
documentation of the medicinal plants has been poorly attempted. The value of
medicinal plants in traditional healthcare practices provides clues to latest
areas of research in biodiversity conservation. Keeping this in view, the
present study has been conducted to study the diversity, distribution and
indigenous uses of medicinal plants in Kullu
district of the Himachal Pradesh. A total 528 economically important plant
species (Angiosperms: 477; Gymnosperms: 09 and Pteridophytes:
42) belonging to 103 families and 294 genera were recorded and used by the
inhabitants of the area. Amongst 528 economically important species, 223
species were used as medicine, 85 species were found to be as wild
edible/food, 175 species having fodder value, 49 species providing fuel, 11
species of timber importance, 44 species of religious significance, 20 of
them being used for making agricultural implements whereas, 11 are being used
as insecticide and 10 of them used as condiments in the study area. Maximum
species (477 spp.) were reported in the altitudinal zone of 2100m-2800m above
msl and species diversity decreased with increasing
altitude in the study area. The continued over-exploitation, habitat
degradation and changing environmental conditions may lead to the extinction
of these species within a few years. Therefore, regular monitoring of
population and habitats using standard ecological methods, development of
conventional and in-vitropropagation
protocols, establishment of species in in-situ and ex-situ conditions
have been suggested. Keywords: Kullu District,

Abstract: The experiment on sixty wheat (Triticum
aestivum L) genotypes was carried out during
2013-14. Evaluation of eleven seed vigour traits viz, length of seed (mm), breadth of seed (mm),
1000-seed weight (g), seed germination (%), speed of germination (in lab),
speed of germination (at field), field emergence (%), shoot length (cm), root
length (cm), seedling length (cm) and vigour index.
Highly significant differences were observed among the genotypes for all the
seed vigour traits.The
speed of germination (at field) showed the highest genotypic coefficient of
variation followed by shoot length, vigour index
and 1000-seed weight. A highest estimate of heritability and genetic advance
was exerted by shoot length followed by vigour
index, speed of germination-at field, 1000-seed weight, speed
of germination-in lab, seedling length and root length. Heritability and
genetic advance indicated that the additive nature of gene action and
reliability of those characters for selection and emerged as ideal traits for
improvement through selection. Keywords:

Abstract: The present study was under taken to find out the genetic
diversity of various maize genotypes for ten metric traits. Ten parental
lines, three testers and their 30F1s were evaluated in a
randomized block design in order to identify genetic divergence on the basis
of non-hierarchical euclidean cluster analysis in
maize (Zea mays
L.). All the genotypes were grouped into seven clusters revealing
the presence of considerable amount of genetic diversity in the material for
different traits. According to results, cluster II, VI and VII each had the
maximum nine genotypes. Cluster I and V had minimum genotypes withfive and two genotypes, respectively. The highest
intra-cluster distance value was found for cluster III (127.613) followed by
cluster VII (68.551) and lowest intra-cluster distance was found in cluster V
(11.517). The maximum inter-cluster distance was recorded between cluster III
and VI (1945.319) followed by cluster III and VII (1279.354) whereas, minimum
inter-cluster distance was observed between clusters I and II (91.049). Based
on results, genotypes grouped into different clusters showed more valuable heterotic pool that could be utilized in crossing the
genotypes selected from those cluster which have maximum inter-cluster and
intra-cluster distance in developing the desirable segregants. Key words:

Abstract: Nutrient management and planting density have become an
important consideration in kinnow management. Kinnow planting and nutrition should zbe
planned so that biological and management aspects are interrelated to
maximize economic returns. Keeping this in view, the study was initiated to
find out the appropriate spacing and nutrition level for Kinnow
in arid irrigated region of Bathinda. The effect of
tree spacing and nutrition on vegetative performance and yield of 6 years old
kinnow mandarins raised on rough lemon rootstocks
were studied at Regional Research Station, Bathinda
during the year 2012-13. Plants were grown at three different spacing viz. S1
(6x6m), S2 (6x5m) and S3 (6x4m) and given three
different levels of nutrition viz. L1 (75% inorganic + 25% FYM), L2
(50% inorganic + 50% green manure) and L3 (100% inorganic only).
Maximum plant height was observed under spacing S3 (3.24 m) and
nutrient level L1 (3.21 m), however, maximum spread (E-W) was
noted under S2 and L2 and spread (N-S) under S1
and L3. Maximum number of fruits per plant (161.66) was counted in
L3 and S2 (155), whereas maximum average fruit weight
was weighed in L2 (150.80 g) and S1 (145.19). Maximum
fruit yield (22.26 Kg/plant) was observed in L3 and S2
(22.40 Kg/plant). Fruit quality in terms of juice and TSS was not affected by
any of the spacing and nutrient levels. However, maximum acidity was recorded

Abstract: In order to rejuvenate the senile guava orchard, 20 year old
guava cv. ‘Allahabad Safeda’ trees were headed back
at the height of 1.5 m, 2.0 m and 2.5 m from ground level keeping the senile
trees as a control in the month of March. These headed back trees were again
subjected to pruning intensity of 0 %, 25 %, 50 % and 75 % of total length of
these newly emerged shoots after 5 months of heading back. The un-pruned
headed back trees were treated as control. The observations revealed that
there was significant improvement of number of fruits and fruit yield per
tree with the age of heading back of senile trees. Although, the mean number
of fruits per tree was lesser in headed back tree than senile tree during the
period of 2010 to 2014, but, among headed back trees highest mean number of
fruits per tree was recorded in plants headed back at 1.5 m. Similarly, fruit
weight and yield per tree was also significantly higher in headed back trees
than senile trees. Among headed back trees maximum average fruit weight and
fruit yield was observed in 1.5 m headed back trees. Intensity of pruning
also influenced the fruit yield and quality. The headed back trees pruned at
50 per cent level performed comparatively better than other pruning levels.
Fruiting density was almost 2.5, 1.8 and 1.5 times higher in trees headed
back at 1.5 m, 2.0 m and 2.5 m, respectively than senile trees. Total soluble
solids and acidity of fruits was also improved with heading back of senile
guava trees. Key words: Guava,

Abstract: Tannase or tannin-acyl-hydrolase (E.C.3.1.1.2.0)
catalyzes the hydrolysis of ester and depside bonds
in hydrolysable tannins, as tannic acid, releasing glucose and gallic acid. The present work explored the production,
optimization of various parameters like pH, temperature, incubation period,
salt-concentration, carbon sources & nitrogen sources and growth profile
of tannase by Bacillus cereus. Tannase from the bacterium showed optimal activity at 48
h and 35°C with 1M salt concentration and initial pH 4.5. The peak enzyme
activity was observed while supplementing sucrose at 1% conc. and maltose at
1 % & 2 % conc. as carbon sources, ammonium chloride at 3% concentration
as nitrogen source. The maximum tannase activity
0.1586 U/ml was recorded in the mid-exponential phase of Bacillus cereus.
Bacillus cereus thus has high potential and may be useful for
industrial production of tannase. Keywords: Bacillus

Abstract: Field investigation was carried out to find out the effect
of number of cuttings on seed yield and quality parameters of multicut fodder sorghum cv. CoFS-29 at Main Agricultural
Research Station, University of Agricultural Sciences, Dharwad during 2012-13. The experiment was laid out
in the Randomized Complete Block Design with four replications, comprising of
five cutting management practices viz., uncut (control) crop, one cut
crop, two cuts crop, three cuts crop and four cuts crop. The results showed
that with increasing frequency of cuttings from zero to four cuttings, the
seed yield and quality parameters have been reduced drastically. Among the
five cuttings, the uncut crophas produced
significantly the maximum number of productive tillers per plant (9.95),
panicle length (42.48 cm), dry fodder yield per hectare at harvest (88.89 q
ha-1), seed yield per hectare (576.4 kg), 1000 seed weight (6.08
g), seed germination (70.00), seedling length (28.15 cm), seedling vigour index (1971) and seedling dry weight (47 mg
seedlings-10) and the least EC value (0.225 dSm-1)
followed by the one and two cuts crops. On the contrary, all these seed yield
attributing and quality parameters were minimum in the four cuts crop.Thus, it is concluded that cutting of the crop at
vegetative stage for fodder purpose is not advisable for seed production of multicut fodder sorghum since the uncut (no cutting) crop
has recorded significantly higher seed yield and quality attributing
components as against the four cuts crop. The next higher seed and fodder
yields with comparable quality parameters could be obtained from the one cut
crop. Key words:

(0, 10, 15 and 20 g/m2) on growth, yield and quality of
chrysanthemum. The interaction effect of phosphorous levels and biofertilizers on plant spread was found to be
significant in first year, while it was non-significant in second year. In
first year (2011-12), the maximum plant spread (19.12 cm) was recorded with
the application of PSB in combination of phosphorus 15 g/m2. The
interaction effect of phosphorous levels and biofertilizers
on number of branches/plant, number of days taken for first flowering, number
of days taken for 50% flowering and fresh weight of flower were found to be
non-significant in both the years of investigation. The interaction effect of
phosphorous levels and biofertilizers on duration
of flowering was found to be significant in first year, whereas, it was
non-significant in second year. The longest flowering duration (45.67 days)
was obtained with PSB in combination of phosphorus 15 g/m2 in
first year. The interaction effects of phosphorous levels and biofertilizers on flower size was observed significant in
first year, whereas, it was non-significant in second year. In first year
(2011-12), the biggest flower (4.50 cm) was obtained with PSB + phosphorus 20
g/m2, which remained at par with PSB + phosphorus 15 g/m2 (4.41 cm). The maximum flower
yield per plant (61.96 and 61.31 g) was recorded with PSB application along

the rainfall and temperature data on daily basis for SRES emission scenarios
(A1B, A2 and B1) under the ECHam5 model for 80 years (2011-2090). The mean
decadal rainfall decreases is decreasing in trend
(approximately 13.2 percent)from 2011 to 2090
showing higher reduction from mid to end of 21st
century. The mean decadal annual rainfall is likely
to be maximum during 2011-20 (774.8 mm) followed by 2021-30 (767.3 mm) and
minimum during 2081-90 (672.4 mm) being statistically similar among the three
scenarios and different among the decades. The decadal maximum temperature is
likely to rise by 18.6, 9.3, 10.4 and 13.0 percent under the four respective
quarters of the year with an average rise of 12.8 percent. However, the
decadal minimum temperature is expected to rise by 50.9, 15.2, 15.7 and 34.6
percent under the four respective quarters of the year with an average rise
of 29.1 percent. The rise of temperature is likely to be greater in case of
minimum temperature especially in first and fourth quarters respectively. Key Words: MarkSim,

Abstract: A total of 30 sheep received for necropsy over a period of 6
months were thoroughly examined. Seventy two tissue samples were collected
from 30 sheep showing the gross pathological lesions of gastrointestinal
tract disorders. Out of which, 48 confirmed isolation of E. coli based
on culture characteristics and biochemical tests and 14 sheep were found E.
coli positive. Infection was prominent in less than one year age groups
and more in male sheep. Out of 48, only 18 strains were sent for serotyping. Out of which, 13 belonged to ‘O’ serogroup, whereas remaining five isolates were untypable strains. The most prevalent serotype was O168(5) followed by O60(4), O1(1), O91(1), O102(1) and
O116(1). In- vitro drug sensitivity pattern by the single disc

Abstract:Twenty CGMS-based pigeonpea [Cajanus cajan(L.)
Millspaugh] hybrids were synthesized manually by
crossing five CMS lines (A lines) with 11 male lines (R lines) and these
hybrids wereevaluated to studyyield
potential with the performance of their R- lines. The results showed that the
restoring capacities of restorer linesare very
important to quality seed production and for yield potential.Result
from the study indicated thatmost of the R- line
acts as good restorer and it ranged from98.50% (ICPL 20108) to 59.22%(ICPL
2009.In present study most of the hybrids showed standard heterosis
towards in desirable direction for yield and yield contributing characters
over the checks so these cross combination of parent may be exploited to
developed the hybrid in pigeonpea for obtaining
higher grain yield.The range of standard heterosis over Asha for grain
yield per plant was ranged from -13.06 (ICPA 2092 x ICPL 20123) to 40.91%

Abstract: The study was undertaken to study the influence of
micronutrients (Zn and B), bio-fertilizers (Azotobacter
and PSB) and pesticide (Imidacloprid) in
sunflower. The experiment consists of fifteen treatments laid out in Randomised Complete Block Design with three replications.
Treatments include application of micronutrients through different methods
like seed treatment, soil application and foliar application in combination
with bio-fertilizers and pesticide as individual applications and in
combinations along with RDF (90:90:60 kg NPK ha-1). The
experimental results revealed that, seed treatment with micronutrients,
bio-fertilizers and pesticide interacted positively in combined
application compared to individual application. Different growth indices like
LAD, AGR, CGR, RGR and NAR are significantly influenced by these methods at
varied rate. Seed treatment with ZnSO4,
borax and bio-fertilizers triggered the early plant growth. Hence recorded
higher seed yield (2186 kg ha-1) compared to RDF alone (1895 kg ha-1).
Seed treatment acts as feasible alternate tool for farmers to improve the
early growth of sunflower (KBSH-53) crop and seed yield. Key words: Micronutrients, Bio-fertilizers, Pesticide, Seed treatment,

Abstract: Papaya (Carica papaya
L.) is a delicious fruit widely cultivated in tropical and subtropical areas.India is first among papaya producing countries in
the world producing around 5.2 million tons of papaya during 2012-2013.
Papaya fruits are highly perishable in nature and postharvest losses of up to
75% have been reported to Hawaii shippers by mainland USA wholesalers and retailers.The present investigation was under taken at
the Department of Processing Technology, College of Agriculture, Vellayani, during 2012-2014, with the objective to
standardize postharvest practices for improved shelf life.The
fruits harvested at ¼ maturity stage and were sanitized with hot water at 50°
C for 20 minutes and warm sodium hypochlorite 150 ppm
for 10 minutes. The fruits were sanitized and waxed and kept in corrugated fibre board boxes with ethylene absorbent potassium
permanganate and kept under ambient temperature were studied. Fruits treated
with hot water at 50° C for 20 minutes with waxing and with ethylene
absorbent recorded highest shelf life of 11 days. Potassium permanganate
reduces the autocatalytic process of ethylene during ripening and hence
delayed the ripening process. In the present experiment all the treatments
with waxing resulted in less mechanical damage suggests that waxing might
have resulted in reducing the severity of bruises in the skin during
transport. Keywords: Papaya,

Abstract: Figs (Ficus) and
fig-pollinator-wasps (Agaonidae) are highly
coevolved mutualists that depend completely on each
other for continued reproduction. In this study these pollination phases of monoecious species- F. racemosa
was studied in three different seasons’ viz., winter, summer and rainy. Alongside this, the efficiency of
pollination was also studied. In general, mean syconia
size is high in summer season followed by rainy and winter season. t-test indicated that while the syconia
sizes differ significantly between rainy and winter.In
rainy and summer seasons foundress wasps started
entering in to syconia after 8 and 12 days
respectively; it stabilized on 16th day
in summer season and on 20th day after synconial development in rainy season. Number of foundress wasps was higher in general in summer (8.22)
followed by rainy (4.17) and winter 2.89; these differences were also evident
in the frequency distribution of number of foundress
wasps in three seasons. Accordingly the four stages viz., A, B, C and D also
differed among seasons. Differences among seasons were more pronounced.
Pollination efficiency as evident by the number of wasps entering the syconia,
was higher in summer followed by rainy and winter season. Similarly the
pollination efficiency measured as the number of wasps and seeds emerging, also showed a similar trend- summer being the
best and least efficient during winter. Key
words.: Fig, Pollination, foundress wasp, Season |
