Effect of integrated nutrient management on growth and yield attributes, yield and nutrients uptake of grain amaranth (Amaranthus hypochondriacus L.)

Abstract

A field experiment was conducted during rabi season of 2018-19 at Agronomy Instructional Farm, S. D. Agricultural University, Sardarkrushinagar, Gujarat to study the effect of integrated nutrient management on growth and yield attributes, yield and nutrients uptake of grain amaranth. Growth and yield attributes such as plant height, dry matter accumulation per plant, length of inflorescence, test weight, grain and stalk yield were recorded significantly higher by the application of 100% RDF + vermicompost @ 1 t/ha + seed inoculation with Azotobacter and PSB followed by 75% RDF + vermicompost @ 1.5 t/ha + seed inoculation with Azotobacter and PSB and 100% RDF + FYM @ 2.5 t/ha + seed inoculation with Azotobacter and PSB. It also recorded significantly higher N and P uptake and net returns.
