Evaluation of different levels of Nutrient and Growth Regulators on seed protein, seed Test Weight and available Post-harvest Soil Nutrient Status in Pearl Millet (Pennisetum glaucum (L)

Abstract

Abstract Field trial was conducted to evaluate the levels of nutrients and growth regulators on quality of seed protein content, grain weight, and soil fertility status in pearl millet in rabi season of 2019-21 at Department of Millets, Directorate of PB&G, TNAU, Coimbatore. The experiment was conducted for three years and ten treatments were tried with replicated thrice. Plant Growth regulator is a chemical substances that help for developing growth of plant, progress for high yield, get superior quality of grain. The treatment 125 % Recommended dose of fertilizer with chlormequat chloride at 250 ppm on 20 and 40 Days after sowing recorded maximum grain protein content, test weight and nutrients uptake during the crop growing period. Simultaneously 125 % Recommended dose of fertilizer with foliar applied chlormequat chloride @ 250 ppm on 20th and 40th days after sowing was indicated more available soil nutrient status after harvest of the crop which was on par with 125 % RDF + NAA @ 250 ppm at 20 and 40 Days after sowing and other Recommended fertilizer dose treatments. The treatments effects were influenced on protein content and test weight of pearl millet with nutrients and growth regulators. The response of pearl millet to applied nitrogen as well as PGRs can be attributed to the favourable effect on yield and yield-attributing characters. This should be due to the reason that nitrogen fertilizer leads to higher availability of nutrients to facilitate promotion of growth and development furthermore resulting in rising yield attributes and yield.
