Abstract: The study was conducted with fourteen ratios of nitrogen (N) and
phosphorus (P2O5) fertilizer with a constant potassium
level (25 kg K2O ha-1). The dry pod yield increased due
to increasing N/P ratios upto 0.78. The treatment
receiving N/P fertilizer ratio of 0.57 (basal application of 20 kg N, 60 kg P2O5,
25 kg K2O ha-1 + foliar application of nitrogen @ 7 kg
N ha-1 at 45 days after sowing and foliar application of nitrogen
@ 7 kg N ha-1 at 60 days after sowing) recorded significantly
higher dry pod yield (4361 kg ha-1), days total number of pods
plant-1 (29.53), number of double and triple seeded pods per 200
pods (181.33 and 36.33, respectively), number of good kernels per 100 g of
kernels (384.67) and less number of shriveled kernels per 100 g of kernels
(17). This treatment also recorded significantly higher leaf area index
(5.817), leaf area ratio (2.228 dm2 g-1), total dry
matter production (39.359 g), more number of root nodules at 45 and 60 (28.13
and 34.80) and their dry weight (0.310 and 0.272 g) respectively. With
respect to economics also the same treatment recorded significantly higher
gross monetary return (Rs. 139522 ha-1) and net monetary return
(Rs. 107448 ha-1) and it was on par with the N/P fertilizer ratios
of 0.70, 0.52, 0.54 and 0.43 (Rs. 106171, 103448, 103323 and 104065 ha-1)

Abstract: Fourty-five hybrids of maize were
developed through Line x Tester design using three male tester lines and
fifteen female inbred lines as parental material along with four standard
checks Pratap QPM hybrid-1, Vivek
QPM-9, HQPM-1 and HQPM-5, to study combining ability in maize (Zea mays L.). The
parents, hybrids and four standard checks were evaluated during kharif season 2014 for 15 characters. Analysis of
variance for means revealed significant differences for all the fifteen
characters studied. The ratio of 2sca / 2gca
was greater than one for all the traits. This indicated that the
preponderance of non-additive gene effects in the expression of these traits.
Among females, EIQ-123 had significant GCA effects for all the traits except anthesis silking interval,
plant height and ear height, indicated that best general combiner for these
traits, while in male parent EIQ-104 was the best general combiner for yield
contributing traits viz., grain yield per plant (11.32), harvest index
(2.93), ear length (0.55), and quality traits viz., oil content
(0.16), starch content (0.75), protein content (0.61), lysine (0.11) and
tryptophan content (0.06). The hybrid EIQ-118 x EIQ-103 (34.41) was the best
specific combination for grain yield per plant followed by EIQ-124 x EIQ-103
(29.65) and EIQ-127 x EIQ-104 (22.15). In addition to above traits, hybrid
EIQ-118 x EIQ-103 also showed better specific combiner for starch content
(6.34), oil content (1.40), lysine (0.78) and tryptophan content (0.21). They
produced significant and desirable SCA effects for most of the traits studied
indicating potential for exploiting hybrid vigour
in breeding programme. Key words:

Abstract: In the present scenario, mechanization of farm operations
for improving efficiency and reducing the cost of cultivation is being widely
adopted in India. Due to non availability of cultivars suitable for
mechanical harvesting in chickpea it is mainly harvested by hand and due to
increasing labour cost, the manual harvesting is
becoming expensive. Hence, present investigation was carried out to
understand the components of genetic variance for the traits related to
mechanical harvesting and yield components. Therefore, 58 diverse lines were
evaluated in RBD with two replications for tallness as well as traits
suitable for mechanical harvesting. All the traits under study showed a wide
range of variation. High heritability coupled with high genetic advance as a
percent over mean was shown by many characters except days to maturity,
number of internodes per plant and stem bio-density. Thus the selection based
on key traits like stem thickness, plant height, internodal
length on main stem, seeds per plant, yield per plant, biomass per plant,
stem bio-density and hundred seed weight would be useful in the chickpea
improvement and pyramiding of traits needed for machanical
harvesting and high yield. Key words: Chickpea,

Abstract: Pollution emanating from agricultural fertilizers, which are
used to increase crop production has posed immeasurable threat to aquatic life
and consequently resulted in negative effects. The effects of sub-lethal
exposure to urea fertilizer especially physiological responses of Clarias gariepinus remain
unknown under a static renewal bioassay. In this study, haematological
and biochemical responses of C. gariepinus
exposed to 0.75, 1.50, 3.00 g L-1 concentrations of urea
fertilizer were investigated for 56 day. The exposure led to significant
reduction in haemoglobin levels, packed cell
volume, red blood cell, mean corpuscular haemoglobin,
with increase in white blood cell, mean corpuscular volume and mean
corpuscular haemoglobin concentration in exposed
fish compared with the control. Leucocyte
differentials showed significant decrease (p<0.05) in neutrophils
and increase in lymphocytes and monocytes counts.
In addition, glucose, alanine aminotransferase,
aspartate aminotransferase
and lactate dehydrogenase levels were significantly
increased (p < 0.05) while protein level was reduced in serum and liver of
the treated fish. The study reports that prolonged exposure to urea
fertilizer can induce physiological dysfunction in C. gariepinus
juveniles. Care should be taken to reduce the influx of these agricultural
fertilizers especially urea in aquatic ecosystem through good management
strategies. Key words:

Abstract: In a mutation breeding experiment, LD50 gives an
indication of the response of different types of explants of a species to
mutagen, so that the right dose(s) for the main field experiment can be fixed
to obtain beneficial mutants with minimal population loss. In the present
investigation, hard wood cuttings of Bougainvillea cv. Lalbagh were treated with fifteen different dosages of
Gamma rays and EMS ranging from 4 to 45 Gray and 8 mM
to 240 mM respectively. The results revealed a
gradual and significant reduction in survival of cuttings, shoot length, leaf
length and leaf width with increase in dosage of both mutagens. There was a
complete inhibition of survival (100 %) over control in the treatments above
25 Gray (Gy) of gamma rays and 200 mM of EMS treatments. Shoot length recorded the highest
in control (34.44 cm and 18.70 cm) in gamma rays and EMS treatments
respectively. Significant reduction of shoot length (1.97 cm), leaf length
(1.50 cm) and leaf width (0.80 cm) were observed in 20 Gy
gamma rays and in EMS treatment, 160 mM
concentration recorded the lowest shoot length (5.67 cm), leaf length (2.10
cm) and leaf width (1.70 cm). The probit curve
analysis based on the survival of treated cuttings exhibited that, LD50
was determined as 5-10 Gray for Gamma radiation and 85.70 mM

Abstract: In an attempt to study the role of nitric oxide and iron sulphate on alleviating lime induced iron chlorosis in three genotypes, it was observed that iron
deficiency reduced the plant growth and development. A field experiment was
conducted at, University of Agricultural Sciences, Dharwad
during kharif 2014. The genotype GPBD-6
recorded higher number of leaves (273) and lower plant height (25.37) at all
the stages. The combination of FeSO4 and
SNP reduced leaf interveinal chlorosis,
and increased the plant height, number of leaves, leaf area and reduced per
cent chlorosis suggesting that nitric oxide action
could be related to iron availability rather than iron sulphate
to the plant. These results suggest that foliar application of nitric oxide
and FeSO4 could alleviate iron
deficiency induced chlorosis of groundnut plants
growing on calcareous soil and helps to restore morphology. Key words: Groundnut,

Abstract: Application for convective drying of ashwagandha
roots was investigated. A laboratory convective dryer which was already
developed had the provision of regulating of air temperature and air
velocity. Ashwagandha roots of uniform size were
used in the drying experiment that were conducted at air temperatures of 40,
50, and 600C, air velocities of 1.0 and 1.5 m/s. Convective drying was carried out
till the moisture content of the ashwagandha roots
reduced from initial moisture content of 5.06 kg water/kg of dry matter to a
safe level of about 0.06 kg water/kg of dry matter. It was found that the
drying time decreased with increasing the drying air velocity. The quality
attributes of fresh and dehydrated ashwagandha
roots were evaluated in terms of colour parameter
(L*, a*, b*) and total alkaloids content. The rehydration ratio was
also determined for dehydrated roots. The quality attributes of the samples
dried by convective drying technique were compared with that of sun drying.
Convective drying of ashwagandha roots was found to
be faster than sun drying. In addition, the quality of ashwagandha
roots dehydrated by convective drying (colour
parameters like L=37.22, a=5.09, b=11.82, rehydration ratio= 3.972 and
alkaloids content= 2.55%) process was found superior to the sun drying
samples (colour parameters like L=35.20, a=4.51,
b=9.51, rehydration ratio= 2.76 and alkaloids content =1.54 %).The process
parameters for convective drying were optimized for ashwagandha
roots using statistical tool ANOVA. Page model wes
best fitted for convective drying condition (R2 > 0.9). The
results revealed that air velocity of 1.5 m/s and air temperature of 500C
gave a good quality dehydrated ashwagandha roots in
convective drying process. Key words: Ashwagandha

Abstract: Cabbage is one of the most important commercial cole vegetable in India. It is widely cultivated in
temperate and tropical parts of India and abroad. It can withstand rough
handlings as well as long distance transport and thus fetch better return in
the market. Therefore, the present investigation was carried out at Bihar
Agricultural University, Sabour during Rabi
season of 2010-11 in Factorial Randomized Block Design for yield contributing
characters in cabbage. The microbial inoculants M1 (Azospirillum) at nitrogen level of N3
(150 kg N/ha) i.e. M1N3 gave significantly highest head
diameter (20.86 cm) and volume of head (23.15’00 ml). This treatment
combination i.e. M1N3 also fetched
significantly maximum net return of Rs. 162745.00/ ha with higher B:C ratio (4.31). However, it was statistically comparable
to N4 200 kg/ ha along with M1 (Azospirillum)
i.e. M1N4 fetching the net return of Rs. 15,71,89.00/ ha with B:C ratio of 4.09. The least B: C.
ratio of 0.73 was registered at nitrogen level of N0 (0 kg N/ha)
on the absence of microbial inoculant (M0)
i.e. M0N0. Therefore, application of microbial
inoculants basically Azospirillum as
seedling treatment as well as soil application of nitrogen @ 150 kg/ha was
the most effective treatment combination for enhancement of yield and
profitability in cabbage cultivation. Key words: Cabbage,
