Abstract:
The field experiments were conducted at Student Instructional Farm of CSAUAT Kanpur, during Rabi 2016-17 and 2017-18. The objective of investigation was to study the effect of foliar applied potassium nitrate and thio-urea 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 (I0) and irrigated (I1) conditions were allocated in the main plots and two wheat varieties i.e., V1 (K-1006) and V2 (K-307) in sub plot and for each five chemical treatments were applied as foliar spray at heading stages by 500 ppm (T3) and 1000 ppm thio-urea (T4), along with control (T0) in sub-sub plots. The significantly higher grain yield (5.30 & 5.12 gm) with best morpho-physiological, phenological and biochemical traits can be obtained by foliar application of 500ppm thio-urea (T3) with both condition of i.e., drought (I0) and irrigated (I1) of wheat crop. Next to this were 500ppm thio-urea (T3) i.e., 5.30 & 5.26, 1000ppm thio-urea (T4) i.e., 5.12 & 5.08 as compare to control (T0) i.e., 4.30 & 4.13 gm. Among cultivars, maximum responsive was K-1006 (V1) in most of traits and gave significantly higher grain yield (5.30 & 5.23) and minimum in K--307 (V2) i.e., 5.12 & 5.08 gm with both concerning experimental years.
