Abstract: A field experiment was conducted to work out optimum dose of foliar application of iron and to evaluate production potential of clusterbean [Cyamopsis tetragonoloba (L.) Taub] varieties. The treatment consisted of combinations of five clusterbean varieties (RGC-986,RGC-1003,RGC-1033, RGC-1055 and RGC-1066) and four foliar sprays treatment of 0.5 % FeSO4 (control, branching, flowering and branching +flowering) were tested in randomized block design with three replications. Results revealed that the highest total N, P, K and Fe uptake (110.8, 13.0, 51.5 kg/ha and 1143 g/ha), seed yield (1816 kg/ha), stover yield (3787 kg/ha), net returns (Rs. 53651/ha) and B:C ratio (2.25), ‘RGC-1033’ proved best and economically profitable compared to rest of varieties. Application of 0.5 % FeSO4 at branching + flowering stage significantly increased quality of seed and stover, seed yield (1550 kg/ha) and stover yield (3624 kg/ha) and proved economically beneficial compared to over control. However, application of 0.5 % FeSO4 at branching recorded at par net returns with spray at branching +flowering stage.

Abstract: India is mainly an agricultural country. Agriculture being a means of livelihood of almost 58 per cent of the population in the country represents India’s most important economic sector. Climate and Agriculture are inextricably linked. Climate change affects agriculture in a number of ways, including through changes in average temperatures, rainfall, climate extremes, changes in pests and diseases etc. Realizing the importance of climate for agriculture production, present study was carried out in different districts of Gulbarga division. Results of the study revealed that, in all the districts namely Bellary, Bidar, Gulbarga and Raichur rainfall showed decreasing trend during the period of study from 1983-84 to 2012-13. Maximum range in the magnitude of average rainfall between the driest and wettest years was observed in Bidar district i.e.; 332.74 mm followed by Gulbarga (316.56 mm), Bellary (228.88 mm), Raichur (222.29 mm) and Koppal (179.70 mm). In Bellary district 80.11% and 86.50% of variation in the yield of Jowar and Cotton was explained by the climatic parameters used in the study. In Gulbarga district84.60% variation in Jowar yield was explained by the variables such as actual rainfall, maximum and minimum temperature and maximum and relative humidity. In case of Raichur district Sunflower and Jowar yield were highly sensitive to the climate variability because 94.30% and 81.56% variation in the yield of Sunflower and Jowar was explained by the variables under study.

Abstract: Spot blotch of wheat caused by Bipolaris sorokiniana (sacc.) Shoem, is one of the most important disease constraints to wheat cultivation in the northeastern and eastern plain zone of India. Bipolaris sorokiniana is also known as the cause of foliar blight, seedling blight, head blight and common root rot of wheat worldwide.A total of 100 genotypes/ germplasm /lines/ genetic stocks were screened under field and epiphytotic polyhouse condition with high pressure by the monoconidial culture of the most aggressive isolate obtained from different climatic zones from India. We found 11 genotypes those were found highly resistant or immune for different aggressive isolate used for inheritance study. Indian genotypes showed to be more susceptible compared to other lines / Genotypes originated from CIMMYT, CHINA and Brazil. Chirya-3 and Yangmai#6 from Cimmyt and China showed highly resistance to the spot blotch under both conditions (Field & Polyhouse). On the basis of the disease frequency these six crosses (Yangmai #6/ GW 322, Yangmai #6/ HD 2967 Yangmai #6/ HD 2985 and Chirya-3/ GW 322, Chirya-3/ HD 2967, Chirya-3/ HD 2985) the data showed good fit to the segregation ratio of 15 resistant: 1 susceptible. P value showed the high significant value (3.841) in all over the crosses. Based upon our studies under both artificial as well as natural epiphytic conditions by using three (F1, F2 and BC1) indicated that resistance in Chirya 3 and Yangmai#6 are governed by dominant genes. Test of allelism also proved that the resistant genes in the Chirya-3 and Yangmai#6 are allelic in nature. A resultant population with combined genome of the resistant lines Chirya-3 and Yangmai#6 with diverse resistant sources would be able to provide defense mechanisms in a way that the yield loss as a result of HLB infection could be significantly minimized.

Abstract: Studies were conducted to know effect of media on quality plantlet regeneration through macro propagation in banana cv. Ney Poovan. Since Ney Poovan is a promising variety in Karnataka and fetches high price in market because of its excellent taste but a major problem in cultivation of Ney Poovan variety is supply of quality planting material. Hence, macro-propagation was tried to see the practicability in using it for large scale multiplication. In this study, effect of growing media on quality plantlet regeneration through macro propagation was tried. Since, banana has strong apical dominance, which when suppressed will give rise to many side suckers. This principle was used in macro propagation. Apical region was removed to encourage lateral buds. For easy penetration of buds incisions were given. Total number of plantlets regenerated after 4-5 months were recorded. Different growing media were used to know the regeneration capacity of corm through macro-propagation. Among different media used media combination of sawdust + FYM significantly produced higher number of primary buds per corm, number of plantlets after secondary decapitation, total number of plantlets per corm and days taken for first bud emergence.

Abstract: The experiment was conducted on rice mustard cropping system with 150kg N+ 75kg P2O5+ 75kg K2O ha-1 in rice crop during kharif 2011. The other treatments included the 125% increased doses of above and sulphur (60 kg ha-1) and zinc (5 kg ha-1) were added since the experimental soil was deficient in these two nutrients. Mustard was grown after rice on the residual nutrients of the same treatments with application of 80 kg N ha-1 uniformly. The results revealed that rice yields varied from 49.0 to 73.0 q ha-1 and NPK raised by 125% with 60 kg S ha-1 and 5kg Zn ha-1 gave the highest yields .The uptake of NPK, S and Zn were also increased significantly. In mustard the seed yield varied from 10.50 to 20.86 kg ha-1 and the highest yield was obtained in the same treatment in case of rice. The results were significant. the variation in oil content was significant but it was higher at lower dose i.e. in case of S60+Zn5 without N.P.K. however the oil yield was a function of seed yield which varied from 4.08 to 8.58qha-1.

Abstract: An experiment was carried out in order to assess the effect of tillage on soil physical properties, crop growth and yield of soybean crop under different sowing methods. The soybean variety JS 97-52 was planted in clay loam soil under three different sowing methods viz. raised bed planter (T1), conventional seed cum fertilizer drill (T2) and zero till drill (T3). It was found that soil moisture content was (16.56%) higher in raised bed planter method as compared to other sowing methods. Maximum bulk density was obtained in zero till drill with 1.71 g/cc at the time of harvesting i.e. 90 DAS (days after sowing) and minimum in raised bed planter with 1.39 g/cc and followed by seed drill with 1.50 g/cc respectively. The results of agronomic observations revealed that the seed emergence,plant height, number of root per plant, depth of root, number of nodules per plant and total grain yield per hectare were,superior in raised bed planter. The second best was seed cum fertilizer drill, while seed zero till drill was found to be less effective. Soybean sown on ridges resulted in greater seed emergence (94.5%), plant height (78.3 cm), depth of root (50.96 cm), number of nodules per plant (135.58), which in turn caused greater grain yield (3137.25 kg/ha), the next best was seed cum fertilizer drill, while zero till drill was not effective as other two methods.

Abstract: Recombinant inbreed lines derived from interspecific cross DS-28 (G. hirsutum) x SBYF-425 (G. barbadense) were utilized to study the genetic variations and divergence for seed cotton yield and its contributing traits in two different locations during 2015-16. The mean values of genotypes indicated existence of sufficient genetic variability. Environmental variances were found greater than the genotypic variances for all the traits except for the plant height and seed cotton yield. Based on per se performance, the DHBR lines 32, 110, 111, 115 and 116 were identified as potential donors for seed cotton yield. Based on morphological and yield contributing traits 150 lines including checks were grouped into eleven clusters on D2 values, indicating high amount of divergence. Seed cotton yield (25.07%), number of fruiting bodies (19.40 %), ginning out turn (14.48%) and boll weight (10.08%) contributed towards genetic divergence and these traits are major determinants of genetic variability in inbreed populations and it as observed that genotypes grouped under cluster XI, II and IX having more than four characters at desirable direction and selection of genotypes under these cluster would be useful to generate desirable genetic resource on inter crosses. Five genotypes, DHBR-32 and DHBR-33 for number of bolls per plant (36.80 and 36.30), DHBR-77 for number of sympodia per plant (21), DHBR-93 for seed index (12.03 g), DHBR-60 for ginning out turn (45.25%) a and DHBR-11 for boll weight (5.95 g) were promising in terms of seed cotton yield and its components.

Abstract: A field experiment was conducted to study the energy balance and system productivity as influenced by various cropping system and soil moisture conservation measures under maize based cropping sequences.In rabi, after maize, the crops were grown under zero tillage with five cropping systems (CS) as main plot treatments viz., Maize-Fallow (CS1), Maize-Toria (CS2), Maize-French bean {(bush type(BT)} (CS3), Maize-French bean {(pole type (PT)} (CS4), Maize-Blackgram (CS5) and four soil moisture conservation (SMC) measures as sub plot treatments viz, no mulch (M0), in-situ maize stalk mulch (MSM) (M1), MSM+Ambrosiasp. 10 t ha-1(M2), MSM+Tephrossiasp. 10 t ha-1 (M3). Results from the experiment revealed that the productivity of all the rabi crops were highest with the use of MSM+Tephrossiaas mulch. Highest maize equivalent yield (MEY) was obtained from Maize-French bean (PT) under MSM+ Tephrossia mulch (9.5 t ha-1) followed by MSM+ Ambrosia mulch (8.8 t ha-1). Maize-blackgram system recorded highest net energy (166054 MJ ha-1)which was 30% higher over maize-fallow system. Energy use efficiency under MSM+ Tephrossia mulch was 5% higher than no mulch. Highest energy intensity was recorded under maize-French bean (PT) system (0.77 MJ kg-1) followed by maize-blackgramsystem (0.61 MJ kg-1). Highest energy productivity was in maize-blackgram(4.24 kg MJ-1). There was 83% increase in energy productivity under maize-blackgram system than maize-fallow system. Highest land use efficiency of maize-blackgram system was recorded (54.79%). Hence, maize–blackgram performed better in terms of energy productivity, energy use efficiency and land use efficiency with the combined use of maize stalk mulch and tephrosia mulch.

Abstract: In this study an empirical model was developed and validated for estimating the direct runoff from a small agricultural watershed (Arang) in Chhattisgarh (India) shown in fig. 1. A Geomorphic Information System (GIS) was used to extract most of the parameters of the watershed from various thematic maps including DEM land use, soil texture, watershed and sub-watershed boundary the remote sensing and field data. The Digital Elevation Model (DEM) was prepared using contour map (Survey of India, 1:50000 scale) of the watershed. Various maps including watershed and sub-watershed boundaries, drainage network and soil texture were generated using topographic map and soil resource data in the environment of a Geographical Information System (GIS). The Geometica image processing software was used to extract the topographic features and to delineate watershed and overland flow-paths from the DEM. Land use classification were generated from data of Indian Remote Sensing (IRS 1D) to compute runoff Curve Number (CN). Data extracted from contour map, soil map and satellite imaginary, viz. drainage basin area, basin shape, average slope of the watershed, main stream channel slope, land use, hydrological soil groups and CN were used for developing an empirical model for estimation of surface runoff. Results revealed that the observed runoff values were having good agreement with the runoff values predicted by the empirical model. Student’s t-test resulted that the means of observed and predicted runoff were found to be similar at 95 percent confidence level. Value of coefficient of determination (r2) were found to be 0.827 in case of empirical model indicated that the predicted runoff values for each selected rainfall events were close to the observed values.

Abstract: Rapeseed & mustard is the important oilseed crop cultivated in many parts of the world for the production of edible vegetable oils, animal feeds and biodiesel. Processing of rapeseed for oil production produces mustard meal as a byproduct. In the present study, fifteen Indian mustard genotypes were evaluated for the study of phytochemicals and antioxidative capacity in fat free meal. The total phenol & flavonoid content was maximum in PDZ-2 whereas di-phenol was maximum in LES-51. The glucosinolate content was observed to be minimum in PDZ-4 (25.44 µmol/g), EJ8-369 (32.74 µmol/g) and EJ8-118 (34.27 µmol/g). The total antioxidant activity based on phospho-molybdenum method varied from 6.66 mg in PDZ-4 to 25.70 mg in PM-29. The highest free radical-scavenging activity was found in LES-49 (38.53±0.705%) followed by EJ8-118 (36.42±2.10%), RLC-3 (35.02±1.54%) and LES-51 (32.77±1.06%) at the concentration of 200 µg/ml. Maximum reducing power activity was found in RLC-4 (1.668±0.002) followed by EJ8-118 (1.416±0.013) andPDZ-3 (1.398±0.019). Ferrous ion chelating activity was found to be maximum in EJ8-118 (38.08 ± 0.56%) at a concentration of 200µg/ml. Thus the defatted meal of investigated Indian mustard genotypes was found to be rich in different bioactive substances with health promoting properties can be utilized in the preparation of functional foods as a viable food ingredient.

Abstract: The present investigation was carried out to study the effect of nitrogen and plant growth regulators on seed production and economics of brinjal (Solanum melongena L.) cv. GJB 3. The experiment was laid out as per randomized block design (Factorial) with three replications. Different nitrogen viz., [N0 (Control), N1 (50 kg N/ha), N2 (100 kg N/ha), and N3 (150 kg N/ ha)] and plant growth regulators viz., [G0 (Control), G1 (50 ppm GA3), G2 (50 ppm NAA) and G3 (500 ppm Cycocel)] were used in the study. The results revealed that application of nitrogen @ 150 kg N/ha recorded significantly the highest plant height (68.59 cm), number of fruits per plant (5.66), length of fruit (11.30 cm), diameter of fruit (8.34 cm), number of seeds per fruit (685.49), seed weight per fruit (3.31 g) and seed yield per plant (18.71 g). Among the different plant growth regulators, application of GA3 at 50 ppm recorded significantly the highest plant height (67.25 cm), number of fruits per plant (5.48), diameter of fruit (7.76 cm), number of seeds per fruit (658.45), seed weight per fruit (3.29 g) and seed yield per plant (18.16 g). Among the treatment combinations, nitrogen @ 150 kg/ha and GA3 50 ppm noted maximum plant height (69.67 cm), diameter of fruit (8.67 cm), number of seeds per fruit (762.51), seed weight per fruit (3.75 g) and seed yield per plant (21.53 g). Significantly the maximum number of fruits per plant was registered in treatment combination nitrogen 100 kg N/ha and GA3 @ 50 ppm. The highest gross return (309984 Rs/ha) as well as net return (219996 Rs/ha) with the highest benefit cost ratio (3.44) was obtained from N3G1 (Nitrogen @ 150 kg/ha with 50 ppm GA3).

Abstract: The natural and plantation forest both have their economic and ecological significance. The community structure, regeneration and diversity status shows the health of the forest/stand which is further necessary to plan its conservation priority, sustainable development and management. Therefore, keeping this view in mind the present study was carried out to evaluate the natural and plantation forest ecosystem of Sarguja forest division of Chhattisgarh with the objective to assess the composition, regeneration and diversity pattern of different layers viz., tree, sapling and seedling. A total of 17 species were recorded in natural forest out of which 9 species comprising 8 families was recorded for tree layer, whereas total of 6 species were recorded in plantation site out of which 2 species with 2 families was found in the tree layer, respectively. In sapling layer a total of 6 species with 6 families was encountered in natural forest while it was 3 species with 3 families for plantation site, respectively. In seedling layer a total of 7 species comprising 7 families were found whereas 6 species with 5 families was recorded for plantation site, respectively. The density varied from 520 to 860 individuals ha-1 for tree layer, 2500 to 5500 individuals ha-1 for sapling layer and 9500 to 16000 individuals ha-1 for seedling layer. The value of Shannon index was highest in natural forest except for the seedling layer whereas the Simpsons index was higher in plantation site except the seedling layer. Species richness is showing the similar trend as the Shannon index whereas the value of equitability was much higher in natural forest than the plantation site, while the value of beta diversity is more in plantation site.

Abstract: Mustard oil holds an important position in the household of India because of its unique flavour and other nutritional properties. The present study therefore, was carried out to evaluate the quality of seed meal of five different genotypes [RH (OE) 0901, RH (OE) 0902, RH (OE) 0903, EC 552578 and Pusa Krishma] of Indian mustard. The methanolic seed meal extract exhibited a concentration dependent elimination of DPPH free radicals. All the five genotypes showed about 50% inhibition in the concentration of 3.0 mg dry seed meal. The high antioxidant activity (20.04 mg/g) was observed in Pusa Krishma while maximum iron chelating activity (32.59%) was observed in the genotype EC 552578. Protein content varied from 31.25 to 37.92%. The maximum methionine and tryptophan content were found in Pusa Krishma (1.09 g/100g protein and 0.88 g /100g protein, respectively). Glucosinolate content ranged from 50.06 to 77.93 m mole/g defatted seed meal.
