STUDIES ON FOLIAR APPLICATION OF POTASSIUM NITRATE ON MORPHO-PHYSIOLOGICAL AND YIELD POTENTIAL IN DIFFERENT WHEAT [TRITICUM AESTIVUM L.] CULTIVARS UNDER TWO CONDITION CONDITIONS

Abstract

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 (morphological, 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 irrigated (I ) conditions 0 1 were allocated in the main plots and two wheat varieties i.e., V (K-402) and V (K-607) in sub plot and for each five 1 2 chemical treatments were applied as foliar spray at heading stages by 0.5% potassium nitrate (T ), 1.0% potassium nitrate 1 (T )along with control (T ) in sub-sub plots.The significantly higher grain yield (5.84 & 5.88 g) with morpho- 2 0 physiological, phenological and biochemical 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.with both concerning experimental years.
