Response of integrated nutrient management on soil health and yield of mustard (Brassica juncea L.) var. Varuna

Abstract

An experiment titled "Response of integrated nutrient management on soil health and yield of mustard (Brassica juncea L.) var. varuna" was carried out, research farm of Soil Science and Agricultural Chemistry, NAI, SHUATS, Prayagraj. The experiment was conducted with nine treatments (T1: RDF NPK 100% + PM @ 2t ha-1 + Sulphur @15 kg ha-1, T2: RDF NPK 100% + PM @2t ha-1 + Sulphur @30 kg ha-1, T3: RDF NPK 100% + PM @2t ha-1+ Sulphur @45 kg ha-1, T4: RDF NPK 100% + PM @5t ha-1 + Sulphur @15 kg ha-1, T5: RDF NPK 100% + PM @5t ha-1 + Sulphur @30 kg ha-1, T6: RDF NPK 100% + PM @5t ha-1 + Sulphur @45 kg ha-1, T7: RDF NPK 100% + PM @7.5t ha -1 + Sulphur @15 kg ha-1, T8: RDF NPK 100% + PM @7.5t ha-1 + Sulphur @30 kg ha-1, T9: RDF NPK 100% + PM @7.5t ha -1 + Sulphur @45 kg ha-1,) in a randomized block design with three replication of each treatment. Before harvesting, measurements of growth parameters (plant height, number of leaves per plant) were made at intervals of 30, 60, and 120 days after sowing (DAS). The number of siliquae per plant, the length of the siliqua (cm), the number of grains per siliqua, the 1000 seed weight (gm), the grain yield (q/ha), the stover yield (q/ha), and the harvest index (%) were all recorded after the harvest. According to the findings, there was an improvement in yield and yield characteristics when RDF NPK 100% + PM @7.5t ha-1 + Sulphur @45 kg ha-1 (T9) combinations were applied.
