Abstract: Sunflower (Helianthus annuus),
which used to be an ornamental plants in India, has in recent times become an
important source of edible oil. The saturated fatty acids, like palmitic acid and stearic acid
constitute only 15 per cent. The main constituent, linoleic
acid ranges from 40-70 per cent. A field experiment was conducted at
University of Agricultural Sciences, Dharwad, India
to study the effect of different levels of sulphur
alone or in combination with sulphur oxidizing biofertilizer in sunflower during kharif
2013.Results indicated that application of 30 kg sulphur
ha-1 with sulphur oxidizing biofertilizer registered higher plant height (195.00 cm),
number of green leaves plant-1 (10.56), Leaf area (dm2)
(26.68), Leaf area index (1.48) and Dry matter production(g plant- 1)
(59.64). However, the significantly lowest growth attributes were obtained in
control. This means that the positive effect of the inoculation with sulphur oxidizing bacteria was the highest when elemental
sulphur was applied. Key words: Growth Attributes, Sunflower, Sulphur

Abstract: A field experiment was conducted at Indian Institute
of Horticultural Research, Bangalore; during 2013-2014 to study the
biochemical changes in the leaf of twelve year old custard apple cv. Balanagarduring off-season flowering.Treatments
contain different pruning levels (25% and 50%) combined with defoliation
chemicals (Urea 5%, Ethrel 2000ppm, Potassium
iodide 1% and Orthophosphoric acid 1%) with
control. Total phenolics, Reducing sugars,
Non-reducing sugars, Total sugars, Proline,
Chlorophyll-a, Chlorophyll-b and Total chlorophyll concentrations were
monitored before treatment application and after treatments application.
Total phenolics, Reducing sugars and Non-reducing
sugars are decreased in treated trees than the before application of
treatments and control, but Total sugar found more in before treatment
application than the control and treated trees, and Proline,
Chlorophyll-a, Chlorophyll-b and Total chlorophyll levels in leaves increased
in the treated trees than the control and before application of the
treatments. Such biochemical changes within the custard apple leaves may have
resulted in greater flowering and fruiting, giving rise to off-season
flowering and fruiting with yield of 10.33 kg per plant in the treatment of
25 per cent pruning + Urea 5 per cent and 25 per cent pruning + Potassium
iodide 1 per cent,than the other treatments. Key words:Custard apple, Balanagar, Off-season, Biochemicals,

Abstract: Globally, sunflower ranks second to soybean among
annual field crops grown for edible oil. Sunflower contains 48-53 per cent
oil and 14 to 19 per cent protein. Functionally, sulphur
significantly influences the yield and quality of crops, improves odour, flavors and imparts resistance to cold; and hence
it is generally considered a “quality nutrient”. A field experiment was
conducted at University of Agricultural Sciences, Dharwad,
India to study the effect of different levels of sulphur
alone or in combination with sulphur oxidizing biofertilizer in sunflower during kharif
2013. Results of the study indicated that application of 30 kg S ha-1
with sulphur oxidizing biofertilizer
resulted in higher seed oil content (39.00%) and oil yield (783 kg ha-1)
over control (34.33%) and (482 kg ha-1), respectively. However,
oil content in sunflower was on par with 30 kg S ha-1 alone
(38.93%) and 20 kg S ha-1 with sulphur
oxidizing biofertilizer (38.43%). Application of 10
kg S ha-1 with sulphur oxidizing biofertilizer recorded significantly a higher (5.73%) sulphur use efficiency. Lower sulphur
use efficiency was observed under control. Key words: Sulphur, Quality and Sulphur

Abstract: Cyanobacteria: A major group of bacteria that occur throughout the
world. They are also known as blue- green algae. Different species of cyanobacteria live in wide variety of habitats-from soil
to fresh and sea waters, as well as in extreme habitats such as hot springs,
soda and salt lakes. Cyanobacteria, which are
characterized by rapid photoautotrophic growth and high speed of biomass accumulation,
are now considered as important renewable energy alternatives for
petroleum-based fuels, like biofuels—biogas,
bioethanol, or biodiesel. In agricultural field cyanobacteria is used as nitrogen fixing bio fertilizer,
for bioremediation co2 sequestration and biofuel
production. This research is based on isolation and identification of cyanobacteria species collected from locations and
assessment of their lipid percentage for biofuel
production as lipid is important source for biodiesel production. Key words: Cyanobacteria, Biomass, Lipid and Biofuel |

Abstract: In the present study, one hundred bread wheat
genotypes were evaluated for assessing the nature and magnitude of genetic
divergence using Mahalanobis’s D2
statistics. The data for twenty five quantitative traits recorded from the
genotypes raised in alpha lattice design with two replications. All the
genotypes were grouped into eight clusters. Cluster IV was largest with
twenty six genotypes followed by cluster II with twenty four genotypes. The
maximum inter-cluster distance was observed between cluster V and VI,
suggesting that the genetic makeup of the genotypes in one cluster differ
entirely from those included in other clusters. Thus, hybridization among
these cluster pairs is recommended for getting high transgressive
segregants in F2 generation. Noteworthy
is that both cluster III and II exhibited high cluster means for grain yield
(kg/ha) and number of grains per spike, cluster VIII for thousand grain
weight, number of spikelets per spike and
sedimentation value and cluster VII for protein content. Cluster VII bears
highest mean value for chlorophyll content at anthesis
(49.40) and during grain filling (after anthesis,
48.28), whereas, Cluster V bears highest mean value for leaf vegetation at anthesis (0.69) and during grain filling (0.50).
Similarly Cluster VIII has the lowest mean value for canopy temperature
before anthesis (22.90), at anthesis
(24.58) and during grain filling (27.20). Among the traits studied, maximum contribution
was made by sedimentation value (45.29%), followed by days to maturity
(18.59%), relative water content (16.24%) and thousand grain weight (8.42%).
Hence, sedimentation value, days to maturity, relative water content and
thousand grain weight together contribute 88.54%
towards total divergence. Therefore, these traits may be given importance
during hybridization programme. Noteworthy is that
cluster II, IV, VI and VIII reflected high cluster means for grain yield,
spike length, number grains per spike, protein content, number spikelets per spike, thousand grain weight, sedimentation
value, and these clusters can be successfully utilized in hybridization
programmes to get desirable transgressive segregants. Key words: D2

Abstract: Genetic divergence among 60 brinjal genotypes was estimated using Mahalanobis
D2 statistic. The genotypes were grouped into seven clusters with
irrespective of geographic divergence, indicating no parallelism between
geographic and genetic diversity. The maximum number of genotypes (36) was
found in cluster I with intra-cluster distance of 20.79 and the maximum
inter-cluster distance was observed in between cluster III and cluster VII.
Hence, genotypes belonging to these clusters may be utilized for involving in
hybridization programme for crop improvement. The
characters of average fruit weight (52.32%), number
of fruits per cluster (14.52%), plant spread at 60 DAT (13.90%) and plant height
at 60 DAT (10.62%) contributed more for genetic divergence. Key words: Brinjal, Genetic diversity, D2

Abstract: One of the major limiting factors of okra is the
incidence of yellow vein mosaic virus transmitted by white fly. Eight
genotypes along with their twenty eight F1 hybrids of okra were
screened for reaction to yellow vein mosaic virus in three replications of
randomized block design under field conditions during June-Sep 2013 at the
Research Sub Station (RSS), Akrot, Himachal Pradesh, India. The results exhibited that out of
eight genotypes, SKBS-11 was moderately resistant, P-20 revealed no disease
incidence whereas the remaining genotypes showed resistant reaction. These
genotypes could be used for further hybrid breeding programme
due to their resistant disease reaction to YVMV. Among 28 F1
hybrids, moderately resistant to resistant reaction was recorded while the

Abstract: Subterranean termites are important pest of the Indian
subcontinent and cause extensive damage to major agricultural crops and
forest plantation trees. Due to long persistence of synthetic insecticides in
soil, entry of residual toxic chemicals in food chain and other environmental
concerns, attempts are being made to characterize microorganisms for
biological control of termites. In this study, 220 bacterial isolates were
obtained from the nest soil collected from termite mounds. Sixty three
bacterial isolates along with eight reference strains were found to kill the
termites under in vitro conditions at 2 days of observation and
killing frequency of different bacterial isolates varied from 5 to 90
percent. Nine isolates i.e., KPM35, KBM79, PBM106, PPM115, PPM126, PPM147,
PPM195, PPM203, PPM204 were found to cause more than 60% killing of termites
in Petri plates even on 2nd days of
observation. Six bacterial isolates i.e., PPM119, PPM123, PPM167, PPM194,
PPM199 and PPM203 caused even 100 percent killing at 5 days of observation.
At 10 days of incubation, forty eight bacterial isolates caused 90 to 100 per
cent killing of termites. To explore the mechanism of termite killing, all
the 71 bacterial isolates were tested for expression of proteolytic,
lipolytic and chitinolytic
activities. Only 20 bacterial isolates expressed proteolytic
activity on modified casein agar medium and proteolytic
activity varied from 1.24 to 2.64 among different bacterial isolates. Lipolytic activity was expressed by 46 bacterial isolates
on tributyrin supplemented medium plates and
fourteen isolates showed very high lipolytic
activity. The range of lipolytic activity varied
from 1.16 to 4.50. Only 21 bacterial isolates expressed chitinolytic
activity on plates containing colloidal chitin and it varied from 1.15 to
2.96 in different bacterial isolates. Nine bacterial isolates i.e., KPM15,
KPM30, KPM31, KPM32, KPM35, PPM94, PPM100, PPM119 and WPS73 showed all the
three enzyme activities. Some bacterial isolates i.e., NBM8, KPM72, PPM147,
PPM162, PPM167, PPM203 and PPM204, which showed high termite killing ability,
did not show any of the three enzyme activities. Thus, termite killing was
not correlated with any of these enzyme activities and probably, some other
compound such as toxin, hydrocyanic acid or siderophore
along with these enzymes may be involved in killing of termites. Key words: Termites,

Abstract: A field experiment was conducted during kharif 2014 at Agriculture College, Navile, University of Agricultural and Horticultural
Sciences, Shivamogga to study the effect of zinc
enriched maize residue compost on growth, yield and economics of maize. The
experiment consisted of 12 treatments was laid out in randomized complete
block design (RCBD) with three replications. The treatments comprise of soil
application of maize residue compost @ 7.5 tonnes
per hectare along with 10 and 15 kg ZnSO4 (T1
and T2), enriched farm yard manure (FYM) with 10 and 15 kg ZnSO4 (T3 and T4),
enriched maize residue compost with 10 and 15 kg ZnSO4(T5
and T6), FYM and MRC at 7.5 tonnes per
hectare along with 0.5 per cent ZnSO4 at
varied crop stages (T7–T9), FYM and MRC at 7.5 tonnes per hectare alone (T10 and T11)
and recommended dose of fertilizer (RDF) alone (T12). The results
of field experiment revealed that application of 7.5 tonnes
of MRC enriched with 15 kg ZnSO4 (T6)
recorded significantly higher growth attributing characters viz.,
plant height (172.63 cm), leaf area (56.88 dm2), leaf area

Abstract: Maize (Zea mays L.) is one of the most important cereal crops
grown in tropical and temperate regions of the world. Despite its high yield
potential, it is giving low yields because of lack of appropriate information
about plant spacing and fertilizer management. Nitrogen, phosphorus and
potassium are the major plant nutrients, which limit normal plant growth.
Increasing productivity per unit area through agronomic management is one of
the important strategies to increase the production of maize grain. Keeping
this in view, a field experiment was conducted at Agronomy research Farm of
C.S. University of Agriculture and Technology, Kanpur (U.P), during rabi season in 2010-11 and 2011-12. The
experiment was laid out in split plot design with three replications. The
main plots were allotted by maize hybrid (DHM-117) and composite (Madhuri) along with three spacing, 45cm x 20 cm, 60cm x
20 cm and 60cm x 25 cm. And sub plots, were tested three fertility levels viz, F1- NPK and ZnSo4
of (120:60:40 and 15 kgha-1) F2 -NPK
and ZnSo4 of (160:80:60 and 20 kgha-1) and F3 - NPK and ZnSo4 of (180:100:80 and 25 kgha-1). The results were revealed that the
maize hybrid (DHM-117) significantly more NPK and Zn content and uptake with
fertility levels of NPK and ZnSo4 of
(180:100:80 and 25 kgha-1) at plant
geometry 60cm x20 cm followed by maize composite (Madhuri).
The maize hybrid (DHM-117) with plant geometry 60cm x 20cm was obtained
significantly maximum grain yield as well as stover
yield compared to plant geometry 60cm x25 cm and 45cm x 20cm, respectively.
The maximum net income (Rs. 108619.2 and 109324.1 ha-1) and B:C ratio (3.15 and 2.97) were noticedwith

out at Gandhi Krishi Vignana Kendra
(G.K.V.K). University of Agricultural Sciences Bangalore, 2011-12. The experiment was
laid in a RCBD design with three replications and three grafts per replication.The grafting operation at 5 months intervals on 6 month
old rootstocks was carried out.
The data on various parameters like girth of rootstock, days taken for sprouting,
number and length of sprouts and percentage of graft
success were studied, Grafting in the month of March recorded
the maximum girth of rootstock irrespective of days of
grafting in mist chamber where the
significantly minimum number of days was taken
for sprouting in the month
of January in mist chamber.
During the entire growth periods, the significantly
maximum number of sprouts was
found in the November.
Among the four months studied, the percent of graft success after 30th, 45th, 60th and 75th day after
grafting, success
was found maximum

Abstract: This study evaluated the relationship between corn (Zea mays L.)
grain yield and normalized difference vegetation index (NDVI) sensor readings
using the Green-Seeker sensor and SPAD values using chlorophyll meter. The
relationships between grain yield and several predictor variables were
determined using linear and nonlinear regression analysis. Categorizing NDVI
and SPAD measurement by phenological stage
indicated that growth stage was critical for predicting grain yield
potential. Poor exponential relationships existed between SPAD, NDVI from
early sensor measurements (V2–V7 leaf stage) and grain
yield. By the tasseling stage (65 DAS), a strong
relationship (R2=0.98) was achieved between NDVI, SPAD and grain
yield. Later sensor measurements (After tasseling)
failed to distinguish variation in green biomass as a result of canopy
closure. This study showed that yield potential in corn could be accurately
predicted in season with NDVI measured with the GreenSeeker
sensor and SPAD measured with chlorophyll meter. Key words: Yield prediction,

Abstract: Irrigation scheduling involves deciding when and how
much water to apply to a field. Good scheduling will apply water at the right
time and in the right quantity in order to optimize production and minimize
adverse environmental impacts. Nitrogen is the key element in the production
of rice and gives by far the largest response. High yielding varieties are
generally more adaptive to nitrogen application and they show increased yield
with increasing nitrogen level up to a certain limit.SHIATS
DHAN 203 cultivar was used in the experiment. Crop water requirement for
paddy crop and irrigation scheduling was determined by CROPWAT software.
Total water requirement was estimated 10225 m3/ha during paddy
production with application frequency of 13. Effect of six different
nitrogen levels i.e. 30, 60, 90, 120, 150 and 180 kg/ha on paddy growth
parameter such as plant height, number of tillers, biomass, SPAD data, leaf
area, flag width, flag length, number of grains per panicle andyield were studied in this experiment. Results showed
that all fertilizer rates significantly increased but maximum plant height
(129.0 cm), number of tillers (30.20), grains per panicle (134), biomass
(1043.33gm), SPAD data (48), leaf area (47.96cm2), flag width

Abstract: A field trial was carried out during 2012-13. Among
the different treatments, inoculation with G. fasciculatum
recorded significantly higher pseudostem girth
(53.02 mm), number of leaves per clump (8.64), number of tillers per clump
(8.64) and cured yield (9.25 t/ha) than the control (uninoculated).
Processing percentage (30.45), curcumin content
(4.42 %) and volatile oil content (1.17 %) were highest in turmeric crop
inoculated withG. fasciculatum.
Among nine bio-formulation treatments, the highest pseudostem
girth (65.62 mm), number of leaves per clump (87.64), number of tillers per
clump (8.93) and cured yield (9.79 t/ha) was recorded by T9
receiving the application of RDF + panchagavya + amritpani + mulch (Sugar cane trash) + Trichodermaspray (2.5 %) on mulch + agnihotra ash + triambakamhoma ashfollowed by T8 (8.91 t/ha) receiving RDF + panchagavya + amritpani + mulch
(Sugar cane trash) + Trichodermaspray (2.5
%) on mulch compared to the lowest in T1(5.45 t/ha) receiving only
RDF (180:90:90 kg NPK/ha and 25 t FYM/ha). Eventhough
turmeric is a nutrient exhaustive crop, the results
confirm possibility of production of turmeric with maximum yield and good
quality produce by applying G. fasciculatum
and bioformulations as against applying only
synthetic fertilizers. Key words: Turmeric, Bioinoculants, Bioformulations, RDF, VAM |

Abstract: Phosphorus fractions are important for evaluation of
their status in soil and understanding of soil chemistry that influence soil
fertility. Amount and distribution of P in different fractions of soil. Soil
P fractionation gives an idea about the soil P supplying capacity to plants.
The dissolved phosphate ion is the only form that plants can take up, yet in
the surface layer of most agricultural soils there is less than 1 mg/L (1 ppm) of dissolved phosphate in the soil solution (soil
water), except in recently fertilized soils. On the other hand, the total
soil P concentration can vary from about 200 to 2,000 ppm
depending greatly on soil parent material. Thepresent
experiment was conducted to evaluate the effect of different nutrient
management. Investigations from researchers have shown the efficacy of the
ion-sink methods especially the resin membranes which extract soil-available
P in a similar manner as plant roots does. It can be employed for a variety
of soil types irrespective of their properties. Key word: Phosphorus availability, Different forms,

Abstract: The selection indices through discriminant
function analysis provides better avenue for simultaneous improvement of
several cane tonnage attributing traits which is of prime goal in sugarcane
breeding. Thirty five clones of sugarcane were evaluated under RBD with two
replications for cane yield and its component characters. Among the seven
characters considered to construct indices, higher relative efficiency of
223.89 per cent coupled with high genetic advance (57.84) was exhibited by
index with seven character combination of number of tillers (X1),
number of millable canes (X2), millable cane length (X3), single cane weight
(X4), pol per cent juice (X5)
and CCS (X6) and cane yield (X7) itself. Though the
selection index comprising five yield component characters had a greater
relative efficiency over direct selection, relatively better efficiency
(209.20%) was also exhibited by three (X1+X2+X3)
character combinations with a genetic gain of 54.05. However, a practical
breeder would prefer to use an index which would lead to maximum possible
genetic gain by using a minimum number of characters. Therefore, it is
suggested that combination of three characters viz., number of
tillers, number of millable canes and millable cane length could be advantageously exploited in
the sugarcane breeding programme. Thus, selecting
plants based on this combination of characters would be more appropriate and
effective in this population to get maximum improvement in cane yield. Key words: Selection indices, Genetic gain, Discriminant

Abstract: Brinjal (Solanum
melongena L.), Onion (Allium cepa L.)
and Chilli (Capsicum annum L.) are the major
vegetable crops grown in the Kalaburagi district of
Karnataka. Krishi Vigyan
Kendra laid down front line demonstrations on these four vegetable crops
introducing improved and hybrid varieties and applying scientific package of
practices in their cultivation. The productivity and economic returns of brinjal, onion and chilli in
improved technologies were calculated and compared with the corresponding
farmer’s practices. Adoption of improved production technology will increase
the average yield 21.88% over farmer practices in onion followed by chilli and brinjal (10.77and
7.09 %, respectively) during the period from 2010-11 to 2013-14. Among
three vegetables brinjal showed highest
technological gap (193.40 q ha-1), followed by onion and chilli (189.18 and 151.38 q ha-1,
respectively) whereas, chilli showed highest
extension gap (49.65 q ha-1) followed by onion and brinjal (24.19 and 20.40 q ha-1,
respectively). Brinjal, onion and chilli recorded higher gross returns (307925, 285421 and
218083 Rs ha-1, respectively), net return (259812, 243171 and
164500 Rs ha-1, respectively) and benefit cost ratio (5.40, 5.75
and 3.07, respectively) in improved technologies as compared to farmer’s
practices. It is suggested that location-specific improved technologies
through frontline demonstration would be needed to bridge the productivity
gap of the vegetable crops grown in the Kalaburagi
district of Karnataka. Key words: Vegetable crops, Front line demonstrations,
