Abstract:
A field experiment on “Effect of integrated nutrient management on growth, yield attributes and yield of Indian mustard [Brassica juncea L. (Czern and Coss)]” was carried out at Agronomy Instructional Farm, Chimanbhai Patel College of Agriculture, S. D. Agricultural University, Sardarkrushinagar during rabi 2018-19. The field experiment was laid out in randomized block design with twelve treatments and three replications. The results revealed that seed yield and stover yield as well as most of the growth and yield attributing characters of mustard were significantly influenced due to integrated nutrient management. Treatment T₁₂ consistently gained superior in plant height of 134.95 cm and 183.46 at 60 DAS and at harvest, respectively. However, it remains at par with treatments T₁₁, T₁₀, T₉, T₈, T₇ and T₆ at 60 DAS and at harvest. Minimum plant height was observed under treatment T1 at 60 DAS and at harvest. Significantly higher number of primary and secondary branches per plant (7.2) and (20.1) were recorded under treatment T₁₂ (50% RDF + 2.5 t FYM + 0.5 t castor cake + Azotobacter + PSB). However, it remains at par with T₁₁, T₁₀, T₉, T₈, T₇ and T₆. Yield attributing characters viz., number of siliquae per plant (260.6), length of siliqua (6.04 cm) and number of seeds per siliqua (13.4) were found significantly superior Abstract ii und retreatments T₁₂ (50% RDF + 2.5 t FYM + 0.5 t castor cake + Azotobacter + PSB). While it remained at par with T₁₁, T₁₀, T₉, T₈, T₇ and T₆ for length of siliqua and with T₁₁, T10, T₉ and T₈ for number of siliquae per plant and number of seeds per siliqua. Significantly higher seed yield (2688 kg/ha) of mustard was also recorded under the treatment T₁₂ (50% RDF + 2.5 t FYM + 0.5 t castor cake + Azotobacter + PSB) and it was at par with T₁₁, T10, T₉ and T₈. Similarly, the same treatment recorded significantly higher stover yield (5329 kg/ha) of mustard and found at par with treatments T₁₁, T₁₀, T₉ and T₈.
