Effect of different levels of integrated nutrient management in mustard (Brassica juncea L.)

Abstract

A field experiment was conducted during the Rabi session of 2020-21 in Jaunpur district which lies Indo-Gangetic plains of Central Uttar Pradesh to study the effect of integrated nutrient management in mustard (Brassica juncea L.). The trial was laid down in randomized block design (RBD) with three replications and twelve treatments viz, T1 100% RDF, T2 100% RDF + Azotobacter, T3 100% RDF + Azotobacter + PSB, T4 75% RDF + 25% N from FYM, T5 75% RDF + 25% N from FYM + Azotobacter, T6 75% RDF + 25% N from FYM + Azotobacter + PSB, T7 50% RDF + 50% N from FYM, T8 50% RDF + 50% N from FYM + Azotobacter, T9 50% RDF + 50% N from FYM + Azotobacter + PSB, T10 25% RDF + 75% N from FYM, T11 25% RDF + 75% N from FYM + Azotobacter, T12 25% RDF + 75% N from FYM + Azotobacter + PSB. Result of this study revealed that there was significant effect on growth and yield parameters. Plant height, number of branches, number of siliques, length of silique, number of seed per siliqua, test weight, seed and stover yield in T6 which was statistically at par with T9, T8, T7, T3. Maximum yield (1807 kg/ha) was recorded in T6. It may be concluded that RDF with organic Manure (FYM) and Biofertilizer (Azotobacter + PSB) is possible to produce more yield in mustard crops cultivated without much soil productivity under Indo-Gangetic plains of central Uttar Pradesh.
