Correlation of soil physico chemical properties with a yield of green gram (Vigna radiata L.) by soil amendments and foliar nutrition under sodic soil condition

In India, about 3.77 million ha of the country's geographical area is affected by sodicity. There an urgent need to minimize further land degradation and restore fertility degraded soils meet growing demand for food. The most effective way overcome salt stress applying nutrients through soil foliar. this context, a field experiment was conducted at Anbil Dharmalingam Agricultural College Research Institute (ADAC & RI), Tiruchirappalli, in summer 2022 study reclamation potential amendments foliar nutrition sodic soil. laid out split-plot design with three replications. treatment comprised viz., M1- Pongamia green leaf manure (GLM) @ 6.25 t ha-1, M2- Pressmud 10 M3-CSR GROMOR 25 kg M4-Gypsum 50 % GR, M5-Gypsum gypsum requirement (GR) + GLM M6-Gypsum GR M7-Gypsum CSR ha-1 M8- Farmers practice, main plots S1- Foliar spray (FS) 3% 30 DAS, S2-FS Brassinosteroid (BRs) 0.2 ppm DAS S3-FS Melatonin 60 sub plots. results showed that ha-1+ FS DAS(M6S2) registered significantly (P=0.05%) lowest pH (8.07), ESP (11.62%), exchangeable Na+ (2.93 c mol (p+) kg-1) higher Ca2+(11.23 kg-1), Mg2+ (8.09 K+(0.82 kg-1). It also increased available (235.6, 24.57 309.6 NPK ha-1) grain yield (1110 gram. However, it on par DAS(M7S2). Hence concluded application along pressmud or combined brassinostroid had remarkable effect reducing sodicity increasing productivity
