parameters of tuberose in the cultivar Hyderabad Single in plot size of 3.0 x
3.0 m.The three pre emergent herbicideslike
pendimethalin 30 EC, oxyflourfen
23 EC and atrazine 5%WP and quizalofop
ethyl as a post emergent herbicides were utilized for this experiment. Black
polythene sheet was the best treatment with respect to quality, yield and
weed control was noticed. To know the greenness Also calculated the weed
control efficiency (WCE) and weed index in all the treatments. Apart from
weed controlling effect, they also greatly impact on soil microorganisms like
fungi(10.-3),47.33 & bacteria(10-5)99.00.
These microorganisms are very much essential for various biological
processes, during the crop growth period. So keeping all these in concern,
soil microbial study was conducted onlywith
different pre emergent herbicides like pendimethalin,
atrazine and oxyfluorfen.
The results were highly significant for cfu (colony
forming unit) count for different herbicides. Due to thisimpact
of herbicides on soil microbial population is only for transient period of
about two weeks from date of spraying and soon after growth will be

Abstract: Maintenance of
seed vigor and viability during storage is a matter of prime concern.
Research on storability of hybrid rice in India is of recent origin. Freshly
harvested seed produce of F1 hybrid rice KRH-2 were dried to safe level
moisture (<15.3%), graded to uniform size and used for the study. The
seeds were treated with seed (T0- Untreated control,T1-
Polymer coating (Polykote @ 3ml/kg of seeddiluted with 5ml of water), T2 - Flowable thiram (Royal flow
40SC) @ 2.4ml/kg, T3- Polymer + Flowable
thiram (Royal flow 40 SC) @ 2.4 ml/kg seed,T4-Vitavax 200
(containing Thiram 37.5% and Carboxil
37.5%) @ 2g/kg seed,T5-Polymer+Vitavax 200 (containing Thiram,
37.5% and Carboxil, 37.5%) @ 2g/kg of seed at
recommended dosage. Seed senescence or deterioration is irreversible and
inexorable process. Amount of moisture in seeds is probably the most
important factor influencing seed viability during storage. It may be
concluded that seed coating treatment of Vitavax
200 (containing Thiram 37.5% and Carboxil 37.5%) @ 2g/kg seed (T4), was found
best followed byPolymer + Flowable
thiram (Royal flow 40 SC) @ 2.4 ml/kg seed (T3)
andPolymer coating (Polykote
@ 3ml/kg of seed, diluted with 5ml of water) (T1) moisture content
of 15.3% for maintaining high germination, vigour
and lowest insect infestation during ambient storage of eight months. Keywords: Rice, Seed

Abstract: Bell pepper
fruits coated with edible coatings such as chitosan
and Aloe vera gel along with packaging was
experimented to study their quality parameters and storage life. Chitosan and Aloe vera
gel coatings with bell pepper creates a semi permeable barrier that controls
gases exchange, reduce water loss and there by maintain tissue firmness,
reducing microbial decay and delays oxidative browning. The fruits coated
with chitosan 1 per cent along with polyethylene
packaging showed minimum loss in weight (18.88 %), maximumfirmness
(3.38 kg/cm2), least TSS (5.03 °B), and retained the
maximum green colour at 12th day of storage.
Whereas, the bell pepper fruits which were not coated with any of the edible
coatings recorded the maximum weight loss (23.57 %), least firmness (1.92

a main crop of Rabi after gram. Residual effect of crop residues on yield of
soybean were studied at farmers field under on farm trial (OFT) program in
2008 and 2009 with following treatments such as (a) in situ mixing of wheat
crop residue by the rotavator (CRMR), (b)
incorporation of crop residues in the field by mould board plough (CRMMB) and
(c) burning of wheat crop residues in the field (CRB). Observation revealed
that increasing pattern of organic carbon from 0.35 to 0.40 % in two years
which is main source of microbial activity which ultimately enhances nutrient
availability in field and produced higher grain yield in CRMR i.e 45.94% higher than CRB and 24.29% higher than CRMB. Key Words: Rotavator, Soybean, Crop Residues, Wheat Residue and

Abstract: An important
mechanism for insect pest control should be the use of fungal entomopathogens. Entomopathogenic
fungi, with its cosmopolitan existence and rich diversity, present a
sustainable solution towards integrated pest management programs. They are endophytes, antagonists of plant pathogens, associates
with the rhizosphere, and possibly even plant
growth promoting agents. These entomopathogens, due
to their eco-friendliness and bio-persistence, are preferred to kill insects
at various stages of its life cycle. The most important entomopathogens
that have been commercially produced are Beauveria
bassiana, Metarhizium
anisopliae. These are classified into different
phylums including Oomucota,
Ascomycota, Chytridiomycota
and Zygomocata. These entomopathogens
have contact mode of action in most cases. It contacts the cuticle, forms appresoria, penetrates into the insect, proliferates,
produces toxins and ultimately kills the insect. The insect host shows
reaction of reduced or increased feeding, behavioral fever, aberrant mating,
and changed ovipositional preferences. The spores
are disseminated by the insect cadaver, air, soil and water. For future
prospects, improvements are needed in the research methods, mass production,
formulation and the application techniques. In this paper, we review the recently
discovered roles played by many entomopathogenic
fungi and propose new research strategies focused on alternate uses for these
fungi. Key

Mudhol to know the effect of site specific nutrient
management on yield, nutrient uptake and nutrient balance sheet of maize
hybrids viz., NK-6240 and 900 M GOLD to five target yield levels (100,
120, 140 q ha-1, RDF and absolute control). The results revealed
that significantly higher grain yield (130.53 q ha-1), stover yield (147.75 q ha-1) and harvest index
(46.91 per cent) was recorded by hybrid 900 M GOLD with target yield level of
140 q ha-1. 900 M GOLD with 140 q ha-1 recorded higher
N, P2O5 and K2O uptake at different phonological
stages as compared to other treatment combinations. However, with respect to
available nutrients NK-6240 with 140 q ha-1 recorded higher

Abstract: A field
investigation was carried out with 60 genotypes of brinjal
to know the nature and extent of genetic variability for growth, earliness, yield and quality parameters. The phenotypic coefficient
of variation (PCV) was higher than genotypic coefficient of variation (GCV)
for all the traits. The presence of narrow gap between PCV and GCV were found
for most of the characters under study. High GCV and PCV (>20%) were
observed for number of primary branches (at 90 and 120 DAT), stem girth at 60
DAT, leaf area (at 60 and 90 DAT), number of fruits per cluster, average
fruit weight, fruit length-diameter ratio, number of fruits per plant, total
yield per plant, yield per plot, yield per hectare, early yield per plant and
phenol content in fruits indicating the existence of broad genetic base,
which would be amenable for further selection. High heritability coupled with
high genetic advance over mean was observed for plant height ( at 60, 90 and
120 DAT), plant spread at 60 DAT, number of primary branches ( at 90 and 120
DAT), stem girth at 60 DAT, leaf area(at 60 and 90 DAT), days to first
flowering, number of fruits per cluster, fruit length, fruit diameter, fruit
length-diameter ratio, average fruit weight, phenol content, early yield per
plant, total yield per plant and per cent dry matter in fruitsindicates
predominance additive gene action. Thus, there is ample scope for improving
these characters through direct selection. Keywords

Abstract: Solar drying is
one of the most important methods to reduce the moisture content from post
harvest product to increase the self-life and quality of the product, which
can be used during non-available periods. Solar drying is done in solar
dryers, which use the solar energy to dry crops, vegetables and Fruits. The
objective of this study solar tunnel dryer using semi transparent polythene
collector with size of 200 micron and study its performance on drying of
bitter gourd. The designed solar dryer consists of a drying chamber, semi
transparent polythene collector, eight trays, an exhaust fan, and a hopper.
Drying parameters of moisture ratio (MR) and moisture content was calculated.
The results of the present study show that the semi transparent polythene
collector temperature developed between 580 to 630 C
and efficiency varied from 40% to 68% and the highest solar intensity was
1058 wave/square on June 14, 2015. The moisture ratio is reduced from 1 to 0
in five days. The moisture content of bitter gourd is reduced from 90% to 10%
in 5 days. Key words: Solar drying,

Abstract: High GCV and PCV
were observed for bulb neck thickness (24.69; 25.06) and bulb yield per plot
(18.25; 18.66). Moderate values of GCV and PCV were observed for number of
rings per bulb (12.27; 13.46). Whereas, lowest GCV and PCV were observed for
bulb diameter (6.51; 6.57), bulb shape index (4.35; 4.67), number of leaves
per plant (8.66;8.80), plant height(9.06;9.13) and
bulb length (5.76;5.97). High heritability coupled with high genetic advance
over mean was recorded for bulb neck thickness (50.10) and followed by bulb
yield per plot (36.80), plant height (18.51) and number of rings per bulb
(23.05). Whereas, high heritability coupled with moderate GAM was observed
for number of leaves per plant (17.32), bulb diameter (13.28), bulb length (11.46)
and bulb shape index (8.34). Moderate heritable values captured with moderate
genetic advance suggests the role of second order gene interaction in
expressing of traits. The number of rings per bulb (0.579; 0.532) exhibited
highest positive significant association with bulb yield per plot at both
genotypic and phenotypic level, followed by plant height (0.534; 0.529), bulb
diameter (0.448: 0.442) and number of leaves per plant (0.433; 0.424),
whereas, bulb length (0.272; 0.265) showed positive non-significant
correlation at both genotypic and phenotypic level. Among all the characters
studied, number of rings per bulb had highest (0.804; 0.444) positive direct
effect on bulb yield per plot at genotypic and phenotypic level respectively,
followed by number of leaves per plant (0.607;0.195),
and bulb length ( 0.416;0.140) at both genotypic and phenotypic level. Key
