Investigate the effect of salt stress on yield and yield attributes of wheat

Abstract

A pot experiment was conducted during rabi season, 2018 in the cage house at Department of Plant Physiology, S.K.N. College of Agriculture, Jobner, Rajasthan to study the Investigate the effect of salt stress on yield and yield attributes of wheat. Wheat cultivars namely Raj-4037 (salinity susceptible) and Raj-3077 (Salinity tolerant) were grown in ceramic pots under salinity conditions (0, 4 and 8 dSm-1). Control plants were provided normal water. Different yield and yield attributes observations were recorded at harvest after sowing in pot conditions. Result revealed a significant decrease were recorded in number of spikes per plant, length of spike, number of seeds per spike, grain yield, biological yield per plant, harvest index and test weight. Reduction in yield and yield attributes contributing parameters on account of salt stress was more in cultivar Raj-4037. On the basis of research findings genotype Raj-3077 observed most salt tolerant and the tolerance was mediated by yield and yield attributes characteristics.
