The field experiments were conducted at Student Instructional Farm of SVNU Sagar, during Rabi 2018-19 and 2019- 20. The objective of investigation was to study the effect of foliar applied potassium nitrate with different doses on plant traits (physiological, biochemical, yield and its components) of two wheat varieties under drought and irrigated condition. It was designed in split-split plot design with three replications. The two conditions i.e., drought (I ) and 0 irrigated (I ) conditions were allocated in the main plots and two wheat varieties i.e., V (K-402) and V (K-607) in 1 1 2 sub plot and for each one chemical treatments were applied as foliar spray at heading stages by 0.5% (T ) and 1.0% 1 (T ) potassium nitrate, along with control (T ) in sub-sub plots. The significantly higher grain yield (5.84 & 5.88 g) 2 0 with physiological, biochemical and yield traits can be obtained by foliar application of 0.5% potassium nitrate (T ) 1 with both conditions of i.e., drought (I ) and irrigated (I ) of wheat crop. In this were represent 0.5% potassium nitrate 0 1 (T ) i.e., 5.31 & 5.27 g, 1.0% potassium nitrate (T ), as compare to control (T ) i.e., 4.39 & 4.35 g. In cultivars, 1 2 0 maximum responsive was K-402 (V ) in most of traits and gave significantly higher grain yield (5.88 & 5.84 g) and 1 minimum in K-607 (V ) i.e., 5.80 & 5.54 g with both concerning experimental years.
