Effect of organic amendments and gypsum on yield & yield attributes of rice crop (Oryza sativa L.) grown on sodic soil

Abstract

A field experiment was conducted at Crop research Farm Daleepnagar CSAU&T, Kanpur (U.P.), during Kharif season 2017 to study the effect of organic amendments and gypsum in rice grown on sodic soil. The 7 treatments were tested in Randomized Block Design with three replications consisted of T1: Control RDF (120:60:60), T2: 50%GR, T3: 25% GR+RS@3tha-1, T4: 25% GR+GM@5tha-1, T5: 25% GR+GM@5tha-1+MB Culture, T6: 25% GR+PM@3tha-1, T7: 25% GR+FYM@5tha-1. On the basis of the results emanated from present investigation, it could be concluded that application of 25%GR +PM@3tha-1 applied in rice to significantly increases growth and yield parameter i.e. plant height at maturity, length of panicle, number of effective tillers hills-1, number of grain panicle-1, test weight, grain and straw yields per plot. It was observed that the treatment T6 gave the significantly better growth of plant yield contributing characters. These amendments were also brought significant improvement in protein content in grain and straw.
