INFLUENCE OF SULPHUR AND ZINC FERTILIZATION ON GROWTH AND YIELD OF INDIAN MUSTARD (BRASSICA JUNCEA L.) IN A VERTISOL

Field experiment was conducted during two successive Rabi seasons of 2022-23 and 2023-24 at research field of Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur to assess the effects of sulphur and zinc levels on the growth and yield of Indian mustard (Brassica juncea L.) grown in under maizemustard cropping in a medium black soil characterized by high clay content and possess 12.78 mg kg -1 and 0.65 mg kg -1 available sulphur and zinc, respectively.The experiment was laid in split-plot design consisting of three levels of sulphur (0, 20, and 40 kg ha -1 ) as main plot treatments and five levels of zinc (0, 2.5, 5, 7.5, and 10 kg ha -1 ) as sub-plot treatments which had been replicated thrice.The results indicated that growth plant height and SPAD value), yield attributes (number of siliquae per plant and seed test weight) and yield (seed and stover) parameters of mustard were significantly affected by levels of sulphur and zinc application.Present study concluded that application of Sulphur (40 Kg ha -1 ) and Zinc (10 Kg ha -1 ) with recommended doses of fertilizers can increase the growth and yield of mustard.
