Abstract :

A field experiment conducted in vertisols (black cotton soil ) during 2009–10 and 2010–11, to study the effect of Potassium, Sulphur and Zinc on number of Nodules ,seed yield and oil content in soybean (Glycine max.L) variety JS–95–60 at Ujjain, M.P. The experiment was laid out in split plot design with three replicates. Experimental plots were treated with various combinations comprising three doses each of potash and sulphur in the form of K2O and bentonite sulphur (Control, 20kg/ha and 40kg/ha) respectively, whereas two doses of zinc in the form of zinc oxide i.e. Control and 5kg/ha were taken in different combinations. It was observed that during both the years, number of nodules, seed yield and oil content, were highly significant at K20S20Zn5 combination dose among all other combination doses. Due to application of K 20kg/h, S 20kg/h and Zn 5kg/h in combination dose, number of nodules increased significantly as compared to control by 91% seed yield increased by 43.2% and 32.7% oil percentage increased by 1.3% and 1.1% in both the years respectively. It was also observed that when doses of potash and sulphur were increased from 20kg/h to 40kg/h each, nodule number, seed yield and oil content all decreased.
