Effect of fertility levels and stress mitigating chemicals on yield attributes and yield of mungbean (Vigna radiata (L.) Wilczek)

Abstract

A field experiment was conducted to analyse the effect of fertility levels and stress mitigating chemicals on yield attributes and yield of mungbean at Agronomy farm, S.K.N. College of Agriculture, Jobner, Jaipur (Raj) during kharif season of 2017. The experiment was laid out in factorial randomized block design (FRBD) and consisted of sixteen treatments combination had equal levels of fertility levels and stress mitigating chemicals i.e. four levels. Among fertility levels, significantly higher number of pods plant-1 (20.51), seeds pod-1 (8.32), test weight (33.50 g), seed yield (1133 kg ha-1), stover yield (2341 kg ha-1) and biological yield (3474 kg ha-1) were recorded under 100% RDF and showed significant superiority over the rest of the treatments while treatment had received 75% RDF (F3) in context to yield attributes and yield showed at par results. Among stress mitigating chemicals application of thiourea @ 500 ppm at flower initiation recorded significantly higher number of pods plant-1 (20.00) and seeds pod-1 (8.18), test weight (32.16 g) seed yield (1048 kg ha-1), stover yield (2276 kg ha-1) and biological yield (3324 kg ha-1)over rest of treatments, but at par with SA @ 75 ppm + 2% Urea.
