    Performance of black gram (Vigna mungo (L.) varieties under rainfed under rainfed farming situation
    (JNKVV, 2016) Patidar, Rahul; Dubey, D.P.
    ABSTRACT The field experiment was conducted at All India Coordinated Research Project for Dryland Agriculture, Kuthulia Farm, College of Agriculture, Rewa (M.P.) during Kharif 2015. The experiment was aimed to find out suitable variety for existing agro-climatic conditions of Kymore plateau and Satpura hills zone of Madhya Pradesh. The rainfall during the crop season was 689.9 mm. The soil of the experimental field was clay loam having pH 6.72, electrical conductively 0.14 ds/m, organic carbon 0.51 %, available N 232.40 kg/ha, P2O5 10.60 kg/ha, and available K2O 229.50 kg/ha. The treatments comprised sixteen blackgram genotypes were laid out in randomized block design with three replications. Recommended uniform dose of N and P2O5 was 20: 40 kg /ha. The entire quantity of these fertilizers was applied as basal at the time of sowing. The seeds @ 20 kg/ha were sown in lines on 9th July, 2015 at 30 cm row to row distance. The crop was harvested at 16th October, 2015. All the recommended cultural practices were followed to raise the crop with the following objectives: To study the growth and development of different blackgram varieties under rainfed condition. To identify the suitable blackgram varieties for rainfed condition. To find out the economics of different treatments. The variety TU 136 attained significantly tallest plants over all the remaining varieties at 15 DAS and at crop maturity (13.80 and 66.00 cm, respectively). This was followed by and at par with TU 98-4 (13.07 cm) at 15 DAS of observation and 63.33 cm at maturity stage. At 30 DAS, PU 35, TU 98-4 and TU 136 genotypes produced significantly higher number of branches (3.67, 3.30 and 3.00/plant) over most of the remaining varieties whereas DU 4 gave minimum branches (1.73/plant). At 60 DAS, the production trend of branches among the different varieties was almost the same as observed at 30 days stage. The variety PU 35 recorded higher number of branches (5.20/plant) over the remaining varieties, followed by and at par with TU 98-4 (4.93/plant), TU 10 (4.73/plant), TU 136 (4.60/plant) and TU 27 (4.47/plant). Out of 16 blackgram varieties, PU 30 attained earliest days to flower initiation (35.67 days), 50 % flowering in 46.33 days and finally crop maturity in 60.67 days. The genotype which matured one day late matured in 61.67 days was JU 2. Contrary to this, the variety PU 35 taken maximum 40.33 days to flower initiation, 51.67 days to 50% flowering, thereby crop maturity became late by thirteen days (73.67 days). Amongst the 16 varieties of blackgram, PU 35 brought about most of the yield-attributes up to almost maximum extent i.e. 27.70 pods/plant, 6.47 cm length of pods, 5.87 grains/pod and 162.39 grains/plant. The 1000-grain weight (48.67 g) was maximum in case of TU 136. Amongst the 16 varieties of blackgram, PU 35 and TU 98-4 produced the significantly higher grain yield up to 843 to 755 kg/ha as well as stover yield up to 2183 and 2159 kg/ha, respectively. But, the non-significantly maximum (31.14%) harvest index was recorded with IVU 88-10. The third best genotype in respect to grain yield was PDU 1 (718 kg/ha) and stover yield was 1931 kg/ha. Among the blackgram varieties, PU 35 proved highly profitable giving net income up to ₹ 59338/ha with B: C ratio up to 4.24. The other best genotypes were TU 98-4 and PDU 1, which gave net income up to ₹ 51609/ha and ₹ 48097/ha with B: C ratio 3.85 and 3.66, respectively. The higher monetary gain from these three varieties was due to their higher grain and stover yields per hectare which fetched higher market price. On the other hand, the varieties like DU 4 recorded the lowest net income (₹ 4287/ha) with B:C ratio 1.25 only. Conclusion On the basis of the field experiment it was concluded that the blackgram variety PU 35 was found superior over rest of the varieties. The maximum grain yield was 843 kg/ha, stover yield 2183 kg/ha. The highest net income of Rs.59338/ha and B:C ratio 4.24bunder the rainfed situation of Kymore plateau and Satpura hill zone of Madhya Pradesh. The other varieties which were able to give good yield under this type of climatic situations are TU 98-4 and PDU 1.

    Studies on mitigation of drought effect through foliar spray of chemicals on soybean (Glycine max L. merril) under rainfed condition
    (JNKVV, 2016) Marksole, Jitendra; Dwiedi, V.D.
    ABSTRACT Soybean (Glycine max L. Merril) is one of the commercial crops in India. Soybean is a crop of multiple qualities, as it is both a pulse and oilseed crop. It contains 40 percent protein and 20 percent edible oil, besides minerals and vitamins. As per survey conducted by SOPA, the all India estimated production 12.98 million tonnes from an area of 12.03 million hectare with productivity of 1079 kg/ha. In Madhya Pradesh the area under soybean cultivation is 6.26 million hectares with the production of 5.95 million tonnes. Although the ecological conditions of the state are congenial for soybean production, but the yield is substantially low (950 kg/ha), despite of the best management practices (SOPA, 2014). A field experiment was conducted during kharif season of 2015, AICRP for Dryland Agriculture, Kuthulia Farm College of Agriculture, Rewa (M.P.) to study the “Studies on mitigation of drought effect through foliar spray of chemicals on soybean (Glycine max L. Merril) under rainfed condition.” Keeping above facts in view, present study has been taken with following objectives to assess the growth and development of soybean as influence by different chemicals spray. To find out the suitable chemical to mitigate drought in soybean. To judge the comparative performance of different chemicals and water spray from control on the basis of economics of treatments. The present experiment was carried out on clayey soil which was medium in organic carbon (0.60 %), available nitrogen (350 kg/ha) and phosphorus (16.50 kg/ha) but high in potassium (333 kg/ha) and neutral in reaction (7.1). The investigation was aimed to study the efficacy of drought effect through foliar spray of chemicals and to determine economic viability of treatments. Eight treatments comprised of water spray,1% KNO3, 1% KCl, thiourea@250g/ha and their combination with trizophos at 25-30 and 55-60 DAS and control plots were laid out in Randomized Block Design with three replications. All foliar spray chemicals treatments were applied in 500 liters of water per hectare, using flat fan nozzle. Different observations on the crop parameters were carried out during the course of investigation. Plant population of soybean was recorded at 20 DAS and harvest. Growth parameters viz., plant height (cm), number of branches per plant, number of leaf were recorded at different time intervals. Yield attributing traits viz., pods per plant, seeds per pod and seed index (100 seed weight) were recorded at maturity. Finally, seed and straw yields were recorded treatment wise. Tabulation and statistical analysis of data were done for testing the significance among the different treatments which are summarized below. The plant population of soybean was not affected under all treatments at 20 DAS and at harvest, indicating that these treatments did not adversely affect the germination and further survival of crop plants. Consequently, plant population was almost similar under all treatments. Growth parameters like plant height, branches per plant, number of leaves per plant were significantly superior in treated plot than control plots. However, foliar spray treatment was better overall treatments closely followed by T3. Yield attributing traits viz., pods per plant and seed index (100 seed weight) were also superior under treated plots as compared to control plots in which these parameters were inferior. Both seed and straw yields were significantly higher under all the treatments receiving foliar spray measure than control plots. Maximum seed yield of soybean was recorded under T8 treatment and proved superior over all the treatments except foliar spray 1% KNO3 + Trizophos@600g/ha (T8) which was found significantly superior over all the treatment. Foliar spray chemical treatments received T8 maximum investment (Rs 17645.80 /ha) to control weeds, while expenditure incurred under treatment (T2) water, (T3) 1% KNO3, (T4) 1% KCl, (T5) thiourea@250g/ha and (T6), (T7) and (T8) combination with trizophos at 25-30 and 55-60 DAS ranged from Rs 15515.80/ha to Rs 17645.80/ha, maximum gross monetary return (Rs 62980.80/ha) was obtained under foliar spray treatment closely followed by T8 1% KNO3 + Trizophos@600g/ha. Though GMR was maximum in foliar spray treatments, but the net monetary returns and B:C ratio were also the highest under 1% KNO3 + Trizophos@600g/ha (T8) closely followed by (T6) thiourea@250g + Trizophos@600g/ha to soybean. Based on the foregoing discussion, the following conclusions could be drawn. Growth and development was better in T8 (foliar spray of 1% KNO3+ trizophos@600ml/ha). The foliar spray of Thiourea@250g/ha and 1% KNO3 is the suitable chemical to mitigating drought in soybean. The grain yield (1390.94 kg/ha), net returns Rs45335/ha and B:C ratio 3.57 were maximum number foliar spray of 1% KNO3 at 25-30 and 55-60 DAS + Trizophos@600ml/ha tank mix compared to other treatments.
