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 effect of ascobin in alleviating the adverse effects of salinity on growth, yield and yield attributes of wheat. Wheat cultivars namely Raj-4037 and Raj-3077 were grown in ceramic pots under salinity conditions (0, 4 and 8 dSm-1). Different concentrations of ascobin (0, 500, 750 and 1000 ppm) were sprayed at 45 and 65 days after sowing. Control plants were provided normal water. Yield parameters were recorded at harvest. Result revealed a significant decrease were recorded in plant height, leaf area, number of effective tillers per plant, plant height, leaf area, number of effective tillers per plant, number of spikes per plant, length of spike, number of seeds per spike, grain yield, biological yield per plant, harvest index and test weight in both the cultivars at 55 and 75 DAS. Parameters were recorded at harvest and anthesis, reduction in plant height, leaf area, number of effective tillers per plant, number of spikes per plant contributing parameters on account of salt stress was more in cultivar Raj-4037. The foliar spray treatment with ascobin up to 1000 ppm significantly increased growth and yield. Reduction in growth, yield and yield contributing parameters on account of salt stress was more in cultivar Raj-4037. On the basis of the above findings genotype Raj-3077 observed most salt tolerant and the tolerance was mediated by growth, yield and yield characteristics.
