Effect of NPK and sulphur on yield of cauliflower (Brassica oleracea var. botrytis L.)

Abstract

A field experiment was conducted at the Horticulture Farm of the Rajasthan Agricultural Research Institute in Durgapura, Jaipur, during the Rabi season of 2019-20. The study included four levels of NPK (0%, 60%, 100%, and 120% of the recommended dose) and four doses of sulphur (0, 20, 40, and 50 kg/ha), result ing in a total of 16 treatment combinations. These treatments were tested using a randomized block design with three replications. The results indicated that the application of 100% of the recommended dose of NPK, along with sulphur @ 40 kg/ha, was the most effective treatment combination for the cauliflower crop. This combination resulted in an average curd weight of 431.81 g, a total curd yield per plot of 122.68 kg, and a total curd yield of 213.24 q/ha.
