Intending to scrutinise the effect of zinc nutrition in mitigating heat stress in late sown wheat crop, an experiment was conducted at Norman E. Borlaug crop research centre and Department of Plant Physiology, CBSH, G. B. Pant University of Agriculture and Technology, Pantnagar, Uttarakhand. Effect of three different Zn treatments soil ZnSO4 treatment (T1), foliar ZnSO4 spray (T2) and soil ZnSO4 treatment+foliar ZnSO4 spray (T3) were studied on three varieties of wheat varieties , UP 2425 (V1), UP 2565 (V2) and HD 3059 (V3) sown at late sown conditions on the dates 24- 12-2017 and 24-12-2018 during first (2017) and second (2018) seasons respectively to expose wheat crop to late sowing induced heat stress. Effect of Zn treatments on growth and yield parameters like plant height, number of leaves, panicle length and 1000 grains weight were evaluated under Zn treatments. Although Zn treatments showed no significant effect on growth parameters, a significant per cent improvement of and was observed for thousand grain weight under Zn treatments over control. | Effect of zinc nutrition in mitigating late sowing induced heat stress in wheat crop
