Abstract:
The study was carried out during autumn season of 2003-04 and 2004-05.The soil
of experimental site was sandy loam, having pH 8.5, organic carbon 0.45%,
total nitrogen 0.04%, available phosphorus 10kg ha-1 and available
potassium 278kg ha-1, therefore, the fertility status was poor.
The treatment comprised of control, RDF, 50% RDF+100kg BOM ha-1,
75% RDF + 100kg BOM ha-1, 100% RDF + 100kg BOM ha-1,
50% RDF + 150kg BOM ha-1, 75% RDF + 150kg BOM ha-1,
100% RDF + 150kg BOM ha-1, 50% RDF + 200kg BOM ha-1,
75% RDF + 200kg BOM ha-1 and 100% RDF + 200kg BOM ha-1.
These treatments were applied to dwarf field pea and Indian mustard under
companion cropping of dwarf field pea and Indian mustard. The sowing of dwarf
field pea and Indian mustard was done in north-south direction with row ratio
of 5:1. Application of 100% RDF in the integration of 100kg BOM ha-1
(T5) and 75% RDF + 200kg BOM ha-1 (T10)
increased the grain yield of dwarf field pea (2258 kg ha-1 in T5
and 2283 kg ha-1 in T10) and Indian mustard (264 kg ha-1
in T5 and 265 kg ha-1 in T10) over control
(1013 kg ha-1 dwarf field pea and 102 kg ha-1 indian mustard) and recommended dose
of fertilizer (1727 kg ha-1 dwarf field pea and 200 kg ha-1
Indian mustard). the nutrients
supplied through 100% RDF + 100kg BOM ha-1 and 75% RDF + 200kg BOM
ha-1 maintained the balance nutrition for dwarf field pea and
Indian mustard in companion cropping system, which culminated to grain
production of both crops. The growth and yield traits of both the crops were
concordant to yields obtained from dwarf field pea and Indian mustard in
companion cropping system. Key words:

Abstract:
Front line demonstrations are the best powerful tool of extension to motivate
the farmer for adoption of an innovation. Forty FLDs were conducted by the
KVK dewas during kharif
season from 2010-11 to 2012-13. All these demonstrations were carried out by
the active participation of farmer’s with the objective to demonstrate the
improved technologies of oilseed production potential. The improved
technologies consist, use of high yielding short duration variety JS 95-60,
proper seed rate, seed inoculation with rhizobium
and PSB culture, integrated nutrient management and integrated plant
management. Demonstrations recorded higher yield over farmer’s practice. The
improved technology gave higher yield of 1938 kg/ha as compared to 1584 kg/ha
in the farmer’s practice. In spite of increase in yield of soybean, technology
gap, extension gap and technology index existed. The improved technology gave
higher gross return, net return with high benefit cost ratio (2.21) as
farmer’s practice (1.94). An average additional investment of Rs 2053/- per
ha coupled with scientific monitoring of front line demonstration and non
monitoring factors were resulted in additional return of Rs 12101/- per ha. Key words:

Abstract:
Among 46 chilli genotypes, the thrips
reaction indicated that 7 genotypes of chilli
showed moderately resistance to thrips, while 37
genotypes showed susceptible and 2 genotypes resulted highly susceptible for
the thrips infestation. Thrips
incidence was found negative and significant correlation with fruit yield
(-0.233), number of fruits/plant (-0.325), number of primary branches/plant
(-0.314). To understand the biochemical basis for host plant resistance,
various biochemical constituents were analysed and
correlated with the thrips incidence. The
biochemical components like non reducing sugars (-0.283) and total
chlorophyll (-0.310) showed negative and significant association with the thrips incidence but reducing sugars (0.332), calcium
(0.358) and sulphur (0.266) resulted positive and
significant correlation with the thrips
infestation. Hence, the plant morphology and biochemical parameters need to
be considered for early identification of resistant genotypes during

Abstract:
A field experiment was conducted during 2013-14 Rabi season. In
present study twenty eight landraces of muskmelon collected from different
parts of Karnataka along with two check varieties (Kashi
Madhu and Durgapur Madhu)
were characterized using PPVFRA DUS guidelines. The experiment was laidout in the Augmented Block Design, only check
varieties were replicated in each of the four blocks once and the nine
accessions of melon local types were randomly allotted for each blocks. Significant genetic variability was observed for
most of the traits. The local melons exhibited wide variability for growth
parameters and yield attributing traits. Growth performance results showed
that the highest leaf blade length was recorded in COHB-006 (7.90cm) followed
by COHB-001 (7.75cm) and highest leaf blade width was recorded in COHB-038
(10.20cm) followed by COHB-019 (10.00cm). Significant difference with respect
to petiole length was also observed and COHB-019 recorded maximum petiole
length (7.50 cm) followed by COHB-001 (6.50cm). Highest ovary length and
width was recorded in COHB-002, COHB-032, COHB-034, COHB-037 (1.5cm) and
COHB-012 (1.6cm) respectively. Based on the observations recorded, 23
genotypes were having monoecious sex form and seven
genotypes were having andromonoecious sex form
including both checks, Durgapur Madhu and Kashi Madhu. There was also
significant difference with respect to yield attributing characters in all
genotypes; highest fruit weight was recorded in COHB-034 (2.8kg). Genotype
COHB-002 (25.00cm) produced longest fruits than the other genotypes. The
highest flesh thickness was recorded in COHB-002 (4.38 cm). This study gives
primary information regarding the genetic diversity existing among local

Abstract:
The present investigation consist of twenty
genotypes of pigeonpea including check WRP-1which
were studied in six different environments. The trials were conducted in a
randomized block design with two replications in six different environment viz.,
kharif-2012, 2013 and 2014, three seasons of irrigated and same three
seasons of rainfed condition. Highly significant
differences among genotypes were observed for all the characters.
Environmental + (Genotype x Environment) interaction was significant for all
the characters except days to maturity, pod bearing length and 100 seed
weight. All the traits under the study except for days to maturity and 100
seed weight showed significant differences in different environments. The
variance due to pooled deviation was highly significant for all the
characters except for primary branches and number of seeds per pod which
reflect the presence of sufficient genetic variability in the material. The
genotypes RVK-275 (X=41.2, bi=1.89 and S2di
= 22.03), AKT-9913 (X =41.994, bi=1.70 and S2di
= 18.25), ICP-8840 (X=37.9, bi=1.70 and S2di
= 23.09) and RVK-285 (X=39.80, bi=1.50 and S2di
= 29.56) were found to be a stable for seed yield per plant, test weight,
primary branches, secondary branches, pod bearing length, number of seeds per
pod and pod length, across the environments with good stability under rainfed and irrigated conditions compared to local check
of the year 2012, 2013 and 2014. Path analysis revealed that days to 50%
flowering (7.11), pod length (4.11), pod bearing length (4.32) and secondary
branches(3.81) at genotypic level similarlynumber
of pods per plant (0.70), 100 seed weight (0.42), days to maturity (0.32) and
pod bearing length (0.32) at phenotypic level had the highest positive direct
effect on grain yield. For maximizing the grain yield per plant emphasis
should be given in selection of such characters for further improvement in pigeonpea. Two years of field screening for Fusarium wilt (FW) and Sterility Mosaic Disease
(SMD), the genotype JSA-59 and WRP-1 is resistance to Fusarium
wilt.JSA-59 and BDN-711 is resistance to SMD. Hence, it can be used directly

Abstract:An
investigation was undertaken with twin objectives of assessing the
variability for grain nutrients among 561 maize inbred lines using NIR
facility and to assess the grain yield potential of 53 selected protein rich
maize inbred lines during summer and kharif-2014, respectively,
following randomized block design with two replications. High genotypic
co-efficient of variation for most of the characters indicated the presence
of higher magnitude of genetic variability among the inbred lines. A close
correspondence between phenotypic co-efficient of variation and genotypic
co-efficient of variation for most of the characters indicated lower
environmental influence and effectiveness of selection. Weak association
between grain yield with crude protein and essential amino acids suggested
their independent genetic control. The inbred lines grouped under different
clusters differed significantly for most of yield related traits. The high
yielding and high crude protein content inbred lines could be used as parents
to develop high yielding-protein rich single cross hybrids. Key words: Clustering,

Abstract:Twenty
seven wheat genotypes were evaluated in Randomized block design for the study
of correlation and path coefficient among the yield and yield contributing
traits. Correlation study at phenotypic and genotypic level showed that grain
yield per plant exhibit positive significant association with harvest index,
test weight, biological yield, spike length, tillers per plant and plant height.
In addition to above characters, flag leaf length and grain filling period
also showed positive significant association with grain yield per plant.
These characters are strongly associated with seed yield in wheat.
Significantly inter correlation among traits is useful for breeding programme to improvement of yield and its components.
Path analysis identified biological yield, harvest index, days to heading,
spike length, grain filling period, plant height and
test weight as highly desirable components for direct effects on grain yield.

Abstract:
Aquatic macrophytes have been widely studied
because of their capability of absorbing contaminants from water and their
subsequent use in biomonitoring. Free floating
aquatic macrophyte Eichhornia
crassipes were treated with various
concentrations of treated tannery effluent, under repeated exposure in
controlled laboratory conditions in order to assess their maximum
bioaccumulation potential. Phytoremediation with E.
crassipes for 9 days improved the physico-chemical properties of the 100% effluent. The
reduction in pH, TS, BOD and COD were 9.52%, 38.90%, 41.42 and 38.27%
respectively. Metal content in the effluent was remained 1.38 mg l-1
after treatment with E. crassipes. The
result showed a concentration and duration dependent accumulation of Cr in
plant tissues. However maximum bioconcentration of
Cr was in roots of E. crassipes (324
µg g-1 fw), followed by leaves (112 µg g-1
fw) in 100% effluent after 9 days of exposure. Physiological
and biochemical responses of the plant viz. total chlorophyll, protein
content and NR activity decreased with increase in effluent
concentration and duration. At highest concentration and duration a maximum
reduction of 32.34% in total chlorophyll content, 42.47% in protein content
and 46.66% in NR activity was found in E. crassipes.
Thus in lieu of above mentioned study E. crassipes

Abstract:
Botanical pesticides are based on plant extracts. Botanical insecticides have
long been touted as attractive alternatives to synthetic chemical
insecticides for pest management because botanicals reputedly pose little
threat to the environment or to human health. The practice of using plant
materials against field and storage pests however has a long history in many
indigenous and traditional farming communities across the world. A number of
plant substances have been considered for use as insect antifeedants
or repellents, but apart from some natural mosquito repellents, little
commercial success has ensued for plant substances that modify arthropod
behavior. In conventional agriculture, botanicals face tremendous competition
from the newest generation of “reduced risk” synthetic insecticides such as
the neonicotinoids. In the context of agricultural
pest management, botanical insecticides are best suited for use in organic
food production in industrialized countries but can play a much greater role
in the production and postharvest protection of food in developing countries. Key words: Botanical

Abstract:
Leaf blotch disease usually appears on lower leaves in winter season starting
period. This disease caused by Taphrina maculans (Butler and Bisby)
and appears as small, oval, rectangular or irregular brown spots on either
side of the leaves which soon become dirty yellow or dark brown. The leaves
turn chlorosis to necrosis. The disease is
characterized by the appearance of several spots on both the surfaces of
leaves. The fungus is mainly air borne and primary infection occurs on
lower leaves with the inoculum surviving in dried
leaves of host, left over in the field. The ascospores
discharged from successively maturing asci
infect fresh leaves without dormancy, thus causing secondary infection.
Secondary infection is most dangerous than primary one causing profuse
sprouting all over the leaves. The integrated approach taken in field demo
trials includes selection of seed material from disease free areas, treating
the seed material with Mancozeb @ 3g/litre of water for 30 minutes and shade dry before
sowing. Spraying of mancozeb @ 2.5 g/litre of water or Hexaconzole @
1ml/litre; two sprays at fortnightly intervals and
at heavy mist-fog season spraying of Copper oxy chloride 3 g/litre effective against leaf blotch disease.During
the month of August to October more rain fall disease severity is high. Key words:Taphrina,

diurnal temperature regime fluctuation influences on pollen sterility in
chickpea (Cicer arietinum

Abstract:
Temperature stress during the reproductive phase in chickpea is generally
allied with lack of pollination, abscission of flower buds, flowers and pods
with substantial yield loss. Hot (>30oC) and dry atmospheric
conditions lead to profligate loss of flower buds and open flowers in
chickpea. A field experiment was conducted during rabi,
2014-15 at Dharwad, Karnataka with three genotypes
(Annigeri-1, JG-11 and JG-14) as influenced by five sowing dates (D). The
investigation revealed that the genotype, JG-14 under D1
temperature regime recorded significantly minimum pollen sterility per cent
(5.18), whereas Annigeri-1 and JG-11 recorded significantly maximum pollen
sterility per cent under D4 temperature regime (43.97 and 42.75).
Similarly, Annigeri-1 and JG-11 showed significant positive correlation with
Tmin and Trange under D1, D2 and
D3 temperature regime. Likewise, JG-11 recorded significant
positive correlation with Tmax under D4 and D5
temperature regime. Eventually JG-14, maintained least pollen sterility per
cent under D1 temperature regime and averagely least under late
sown and high temperature conditions than Annigeri-1 and JG-11. Apparently D1
temperature regime experienced least pollen sterility per cent and proved to
be best sown condition for maximum pollen viability than lateral temperature
regimes. Key words:

Abstract:
Nursing the profession of caring for the sick and the convalescent, the
disabled and helpless, is one of the noblest profession throughout the world.
Nursing coversrange of function in their hospital
and they are required to work at any point in the 24 hr day. Therefore,
stress in the nursing profession is an ongoing worldwide problem. The present study was carried out to assess the
physiological and psychological assessment of work. The descriptive data was
collected with the help of interview schedule. The experimental data was
gathered into different section such as physiological parameters (EE, HR and
TCCW), postural discomfort scale (Nordic scale and REBA sheet) and
psychological parameters (VAS, FSS). Total 120 nurses were selected through
simple random sampling method in the 4 district uttarakhand.
The result revealed that nurses were suffered from upper back pain (66.67%)
and lower back pain (64.17%) due to awkward posture and inappropriate work
station. In postural analysis through REBA, patient handling activity was
fall in AL4 category which showed very high risk and requires immediate
change in working posture. The highest physiological cost of work found in
patient handling activity that is EE 9.98 kj/min,
HR 117.58 beats/min, TCCW 895.55 beats. In psychological test that is VAS,
nurses were reported very severe pain in their neck (18.33%), whereas in FSS
score was found 79%. Paired t test was used for statistical analysis to
compare mean heart rate of the nurses and found to be highly significant at
(P>.001).To improve their health and work life style, possible guidelines
were suggested at individual and organizational level to cop up work stress
and perform better job demand. They required stress relieving training.

Abstract:
Asparagus racemosus is an important
medicinal plant commonly called Satavari considered
both a general tonic and a female reproductive tonic with ability to increase
fertility and vitality. Charak Samhita
written by Charak and Ashtang
Hridyam written by Vagbhata,
the two main texts on Ayurvedic medicines, list Asparagus
racemosus as part of the formulas to treat
women’s health disorder. Due to its multiple uses, demand for A. racemosus is constantly on the risehowever,
the supply is rather erratic and inadequate. Destructive harvesting, combined
with habitat destruction in the form of deforestation has aggravated the
problem. There is a need for conservation of this plant. To overcome these
prevalent problems, the availability of genetically superior and uniform
planting material is essential. The seed mediated propagation is
unsatisfactory due to dormancy and low germination percentage. This however,
decelerates the conservation strategy of this species. Thus efforts were made
in this study to break dormancy and improve germination of seeds by different
growth regulators for boosting conservation. The TZ (Triphenyl
tetrazolium chloride) test showed 97%of viable
seeds. The present investigation was carried out to study the influence of
different growth substances on seed germination, length of root and shoot and
vigour index. The seeds were soaked in different
growth regulators like GA3, NAA and KNO3 with different
concentration to evaluate their effect on germination at a constant
temperature of 250C, it was found that GA3 300 ppm had a highest significant effect on germination as
compared to control and all other treatments at a constant temperature on top
of the paper substrata, but as the concentration increased above 300 ppm the germination decreased rapidly. Key words: Asparagus
