Effect of Potassium & Zinc on the Growth and Yield of Mustard (Brassica juncea L.)

A field experiment was carried out at an agricultural research farm in the Rabi season 2022, department of Agronomy Sam Higginbottom University Agriculture, Technology and Sciences, Prayagraj North Eastern plains Uttar Pradesh to study growth yield Mustard (Brassica juncea L.) Var. with effect potassium zinc, under Randomized block design comprising 10 treatments which treatment (T1-T9), Using three replications nitrogen, phosphorus, potassium, zinc different combinations T1 – 30 kg K/ha + 5 Zn/ha, T2 T3 15 T4 40 T5 T6 T7 50 T8- T9 Zn/ha T10 Control. The exploratory plot’s soil had a sandy loam texture, (pH 7.2) that natural EC - 0.26 (dS/m), low organic carbon (0.48 %), available N (225 kg/ha), P (13.60 kg/ha) K (215.4 kg/ha). experimental results revealed recorded Maximum plant height (193.45 cm), highest dry weight (35.25 gm), number siliqua/plant (302.20), seeds/siliqua (17.60), Seed (2685 Stover (6143 when compared other combinations.
