Abstract:
Field experiment was conducted during summer 2020- 21 and 2021-22 at Agricultural College Farm, Raichur to know the effect of different stress mitigating compounds on morpho-physiological characters, yield and yield components in groundnut under soil moisture stress. Experiment was laid out in randomized block design with three replications. The data indicated that plant height, leaf area per plant and total dry matter per plant was significantly lower in water stressed treatments compared to all other treatments. Pod yield of groundnut was significantly higher in normal irrigation (30.7 q ha^-1) over water stressed treatments (21.8 q ha^-1). Among the stress mitigating treatments however maximum pod yield was obtained in the treatment foliar application of triacontanol @ 2.0 ml/l (29.4 q ha^-1) followed by KCl @ 1.0 percent (27.9 q ha^-1), kaoline @ 6 percent (27.3 q ha^-1) and methyl jasmonates @ 20 ppm (26.0 q ha^-1). However Economic analysis of different stress mitigating treatments in groundnut crop revealed that foliar application of kaoline (6%) had higher cost of cultivation and triacontanol (2 ml/l) had higher gross returns, net returns and B:C ratio followed by KCl (1%) and methanol (2%) respectively. However, lower net returns and B: C ratio was obtained with stressed plot.
