Abstract

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