Effect of Sulphur and zinc with combination of FYM on yield and uptake of nutrients in Mustard (Brassica Juncea (L.) under Alfisols of Odisha

A pot culture experiment was conducted in Alfisols to study the effect of sulphur and zinc fertilization, separately and their combination with Farm Yard manure on the yield and nutrient uptake by rabi mustard (Var. Andhra Keveri) with a design of CRD. The treatments were four levels of sulphur (0, 20,40 and 60 kgha-1), two levels of Zinc (0 and 2.5 kgha-1) and two levels of FYM (0 and 10 tha-1) with three replications and recommended doses of Nitrogen, Phosphorus and Potash. The results revealed that highest seed yield (1.71 g/pot) of mustard was found in the treatment of sulphur @60kg ha-1 + zinc @ 2.5kg ha-1 along with FYM @ 10t ha-1. The application of only sulphur @ 60 kgha-1 yielded 1.03g/pot over control whereas application of only Zinc @2.5 kgha-1 yielded 59.7% over control. Similar trend were observed in case of stover also. Higher uptake of Nitrogen, Phosphorus, Potassium, Sulphur and zinc were found by the application of Sulphur @60 kgha-1 + Zinc @2.5 kgha-1 and FYM @10 tha-1. The positive interaction effect of Zinc with Nitrogen, Potash and sulphur were found whereas antagonistic effect with Phosphorous was observed.
