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.

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.

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.

Abstract: The pot experiment consisted of four sources of sulphur (Cosawet sulphur, Gypsum, Bentonite sulphur and Elemental sulphur) at five levels of sulphur (0, 5, 10, 15, and 20 mg kg-1). The experiment was laid out in a factorial completely randomized design. Groundnut variety GG-7 was tested in the experiment, in respect of concentration and uptake of nutrient (N, S, Ca,) at different growth stages of groundnut crop and their availability in post harvest soil. The experimental soils were vertic haplustepts medium black calcareous clayey which was slightly alkaline in reaction pH(7.8) and EC (0.58 dSm-1) low available nitrogen (242 kg ha-1), medium in available phosphorus (39.20 kg ha-1) and high available potash (336 kg ha-1). The application of elemental sulphur resulted significantly highest nutrient content(N and S ) in plant at 60 DAS and at harvesting stage. Whereas Ca content was non significant at 60 DAS and harvesting stage. Significantly highest concentration of N (1.27 %) and S (0.226 %)in plant were observed with the application sulphur @ 20 mg kg-1 at harvesting stage. The Ca content in plant was non significant at 60 DAS and harvesting stage with increasing level of sulphur.Application of elemental sulphur @ 20 mg kg-1 produced significant effect on uptake of N (353.4 mg plant-1and 217.0 mg plant-1) and S (52.6 mg plant-1 and 92.0 mg plant-1), whereas Ca (317.0 mg plant-1 and 534.0 mg plant-1) uptake was found significantly superior with application of gypsum @ 20 mg kg-1 at both the stage of plant.

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 for EMS.

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.

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.

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, Nitrogen, Azospirillum, Yield, Net return, B: C ratio.
