Effect of foliar application of thio-urea on biochemical parameters in Wheat (Triticum aestivum L.) cultivars

These experiments have been conducted in order to study the effect of foliar application of thio-urea doses on biochemical of two varieties in two sowing conditions at Student Instructional Farm of C. S. Azad University of Agriculture and Technology, Kanpur during the Rabi season of 2017-18 and 2018-19. The experimental design was split-split plot design in which sowing conditions was in main plot (D1 timely sowing, D2 late sowing), two cultivars (V1: K- 607, V2: K- 402) in subplot while five treatments in these one doses thio-urea (T1 500ppm, T2 750ppm, T3 1000ppm, T4 1500ppm) with control T0 water spray in sub-sub plot with three replications. Results showed high significantly effect of sowing condition, variety and treatment on Chlorophyll (SPAD) Value-sown condition (D1 over late sown condition D2 with 42.1 and 41.8; 41.6 and 41.8), effect of treatment- T1 (2.3 and 2.3) followed by T2 (2.2 and 2.2), T3 (2.2 and 2.1) while, least chlorophyll value was in treatment T4 (2.1 and 2.0) and T0 (1.8 and 1.8) in both years of experimentation. Fat Content (%) timely sown condition (D1 i.e., 0.98 and 0.97 as compare to late sown condition D2 i.e., 0.97 and 0.96), effect of variety (V1 with 0.98 and 0.97 g and V2 with 0.97 and 0.96) and effect of treatment T2 (1.04 and 1.03) had showed statistically higher fat content followed by T4 (0.98 and 0.96), T3 (0.96 and 0.93) and T1 (0.94 and 0.96) while lowest in treatment T0 (0.93 and 0.97) during both year of experimentation. Protein content (%) effect of condition (Maximum protein content (11.5%) accumulated in D1 while, minimum (11.0%) in D2), effect of variety highest (11.5%) protein content numerically recorded in V1 and lowest in V2 (11.1%) and effect of treatment T2 gave statistically maximum mean value T0 (11.7 and 11.8) protein content (%) during these experimentation were found significantly with sowing conditions, varieties, treatments and their interaction in both years. Totally conclusion that timely sowing date (D1), cultivar (V1), and treatment (T2 thio-urea 750ppm) were superior to others.
