Effect of integrated nutrient management on timely sown crop of Indian mustard (Brassica juncea)

A study was conducted during the winter (rabi) season of 2020–21 at the Maharishi Markandeshwar University, Ambala, Haryana to assess the effect of integrated nutrient- management on timely sown crop of Indian mustard (Brassica juncea (L.) Czernj & Cosson). The experiment consisted of 8 treatments, viz. T1 , Azotobacter + 100% recommended dose of fertilizers (RDF); T2 , Azotobacter + FYM 5 t/ha + 50% RDF; T3 , 100% RDF; T4 , control; T5, Azotobacter + vermicompost 5 t/ha + 50% RDF; T6 , Azotobacter + phosphate solubilizing bacteria (PSB) + 100% RDF; T7 , Azotobacter + PSB + FYM 5 t/ha + 50% RDF; T8 , Azotobacter + PSB + vermicompost 5 t/ha + 50% RDF, which were replicated thrice and laid out in the randomized block design. The results depicted that the growth and yield attributes such as no. of primary branches/plant (9.40), no. of secondary branches/plant (19.03), dry-matter accumulation (99.10 g/plant), plant height (210.47 cm), seeds/siliqua (13.90), siliqua/plant (371.63), length of siliqua (5.17 cm), 1000-seed weight (6.00 g) and as well as seed yield (2.28 t/ha) and straw yield (2.03 t/ha) were found highest under T8 .
