Response of Indian mustard (Brassica juncea L) to drought alleviating microbes under different irrigation regimes in North Gujarat region

Abstract

A field experiment was conducted during the Rabi 2022-23 in a split plot design with twelve treatment combinations comprising three irrigation schedules (0.6, 0.8 and 1.0 IW/CPE ratio) and four drought alleviating microbes (control, MRD-17, CRIDA MI-I and CRIDA MI-II). The results revealed that significantly higher seed yield (2045 kg/ha), stover yield (5204 kg/ha), higher total N, P, K and S uptake by crop were recorded with irrigation scheduled at 1.0 IW/CPE ratio. However, higher field water use efficiency (FWUE) was found with irrigation scheduled at 0.6 IW/CPE ratio. Inoculation of seed with CRIDA MI-I secured significantly higher oil yield (782.7 kg/ha) seed yield (2018 kg/ha), stover yield (5277 kg/ha), FWUE and nutrient uptake.
