Effect of gypsum application on Seed yield, total moisture use and moisture use efficiency (MUE) of soybean and chickpea

Abstract

A field investigation relating to Studies on the Effect of gypsum application on Seed yield, total moisture use and moisture use efficiency (MUE) of soybean and chickpea. Was conducted at Agronomy farm, College of Agriculture, Nagpur. The field experiment was laid out in randomized block design (RBD) with a seven treatments replicated thrice. Treatments consisted of 1, 1.5, 2, 2.5, 3, 5 t gypsum per hectare and a control. The samples were taken from (0-30 cm) and (30-60 cm) depth for conducting study. However MUE of soybean significantly increased with increasing level of gypsum. Higher MUE was found with T6 (3 t gypsum ha-1) but T3 (1.5 t gypsum ha-1) is enough to increase MUE of soybean significantly over no gypsum. Increasing level of gypsum also increase the MUE of chickpea. The surface soil of experimental site was slightly alkaline in reaction clayey in texture, medium in organic carbon (6.21 kg-1), low in available nitrogen (206.98 kg), medium in phosphorus (19.23 kg ha-1), high in potassium (503.00 kg ha-1) poor in hydraulic conductivity (1.06 cm ha-1) 1.5 t gypsum ha-1 is enough to increase the yield of soybean significantly over control and increasing level of gypsum increases the yield of Chickpea linearly.
