Abstract:
A field experiment was conducted during kharif seasons of 2018-19 and 2019-20 on clayey soil at Research Farm, Department of Agronomy, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani. The experiment was laid out in split plot design with three replications consists of twelve treatment combinations comprising of three plant growth regulator treatments in main plot and four micro-nutrient treatments in sub plot. It was resulted that among application of plant growth regulators, Brassinosteroids @ 0.01% improved fibre quality parameters like, upper half mean length (UHML) (mm), Micronaire (µg inch^-1), bundle strength (g tex^-1), minimum maturity (%) and minimum breaking elongation (%) during year 2018-19 and 2019-20 as compare with other plant growth regulators. Fibre quality data was improved with Brassinosteroids @ 0.01% followed by Mepiquat Chloride and NATCA during both the years of study. Among application of micro-nutrient treatments, fibre quality data was improved with Foliar spray at square formation and at flowering of 0.5% ZnSO₄ + 0.5% MgSO₄ + 0.5% FeSO₄ + 0.2% B (M₃) which was followed by foliar spray of Grade II micro-nutrient at square formation and at flowering (M₄) during year 2018-19 and 2019-20. Fibre quality data found non-significant with application of plant growth regulators and micro-nutrients during both the years of study.
