Abstract:
A field experiment was conducted to study the effect of Effect of Nutrient Management and Irrigation Scheduling on Performance of Indian mustard (Brassica juncea L.) during Rabi season of 2020-21 at Crop Research Centre of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut (U.P.). The soil of the experimental field was well drained, sandy loam in texture and slightly alkaline in nature. It was low in organic carbon and nitrogen but medium in available phosphorus and potassium with anelectrical conductivity (1:2, soil: water) of 1.65 ds/m. The experiment was laid out in split design with three replications. The rabi season experiment comprised of five levels of irrigation scheduling Growth stage (I₁), Pre flowering stage (I₂), Growth + siliqua stage (I₃), Pre- flowering + siliqua stage (I₄), Growth + Pre- flowering + siliqua (I₅). and five level of nutrient management viz.; Control (N₁), RDF (120:60:40:40) (N₂), RDF + Zn + B (N₃) 75% RDF + 6 tonne (FYM) 25% (N₄), 75% RDF + 6 tonne (FYM) + Zn + B (N₅) were tested in Split Plot Design (SPD) with three replications. The mustard variety Pusa Vijay was grown. The growth and yield, nutrient uptake as influenced by different treatments were assessed. The yield attributing characters like length of siliqua^-1, number of siliquae plant^-1, seed siliqua^-1, and 1000- seed weight exhibited variations due to different irrigation scheduling and nutrient management the highest mean length of siliqua, number of siliqua plant^-1, seed siliqua^-1, and 1000- seed weight was recorded under the treatment of Growth + Pre- flowering + siliqua (I₅) and 75% RDF + 6 tonne (FYM) + Zn + B (N₅). The highest seed yield, stover yield and biological yield was recorded in Growth + Pre- flowering + siliqua (I₅) and 75% RDF + 6 tonne (FYM) + Zn + B (N₅) and the lowest seed yield, stover yield and biological yield was recorded in Growth stage (I₁) and Control (N₁). Gross income and net profit were found significantly higher with the combine application of Growth + Pre- flowering + siliqua (I₅) and 75% RDF + 6 tonne (FYM) + Zn + B (N₅) (Rs. 108318 and Rs. 82688), respectively over rest of treatment and benefit: cost ratio was significantly affected by application of Growth + Pre- flowering + siliqua (I₅) and 75% RDF + 6 tonne (FYM) + Zn + B (N₅) alone with mean value 2.53 followed by remaining treatments. Thus, it may be concluded that application of Growth + Pre-flowering + siliqua (I₅) and 75% RDF + 6 tonne (FYM) + Zn + B (N₅) treatment, seems to be best option for achieving higher yield and net returns by mustard crop.
