Alleviation of Sodicity Stress in Green Gram and Black Gram Using Plant Growth Regulating .......
In India, the majority of pulses are grown in low-fertility soils with volatile environmental conditions. Bad establishment and a low harvest index are two major issues in pulse output. The harvest index for pulses is just 15-20%. Physiological manipulations such as hormone and nutrient spraying minimise flower drop, allowing for a larger sink scale. The aim of this study is to see how growth-regulating substances affect black gramme and green gramme germination, establishment, and economic yield under Sodic soil conditions. Anbil Dharmalingam Agricultural College and Research Institute, Trichy, is the study spot. Soil is naturally sodic, with an exchangeable sodium percentage (ESP) of 18.94% and a pH of 9.02. Under sodic soil conditions, the two crop varieties green gramme VBN (Gg) 2 and black gramme VBN (Bg) 6 were used. Ten treatments were tested in the field from late July to October 2017 under sodic soil conditions. With three replications, the experiment was set up in a Randamized Block Design. At the flower initiation and pod initiation stages, foliar spray was applied. T1: Control, T2: Seed Treatment (ST) with Ammonium Molybdate (AM) 0.05 percent + foliar spray of ZnSO4 – 0.5 percent used ten treatment combinations. T3: AM 0.05 percent + Panchagavya -3.0 percent, T4: AM 0.05 percent + foliar spray of KCl -1 percent, T5: AM 0.05 percent + foliar spray of KCl -1 percent, T6: AM 0.05 percent + foliar spray of KCl -1 percent, T7: AM 0.05 percent + foli T5: ST with GA3 50 ppm + 0.5 percent ZnSO4 foliar spray, T6: GA3 50 ppm + Panchagavya -3.0 percent, T7: GA3 50 ppm + KCl -1 percent, T8: GA3 50 ppm + KCl -1 percent T8: Cowpea Sprout Extract 2 percent + ZnSO4 – 0.5 percent, T9: Cowpea Sprout Extract 2 percent + Panchagavya -3.0 percent, T10: Cowpea Sprout Extract 2 percent + KCl foliar spray -1 percent In conclusion, the best treatment increased yields due to the presence of bioactive substances in sprouted cowpea extracts, and panchagavya was found to be successful in increasing yields.
