Abstract

An experiment was conducted to find out the efficiency of foliar application of nitrogen and zinc on quality of cauliflower (Brassica Oleracea var. Botrytis L.) cv. Snowball-16 at Horticulture Farm (Vegetable Section) Rajasthan College of Agriculture, Udaipur in a clay loam soil having alkaline pH (8.0). The experiment was laid out in RBD with foliar application of four nitrogen levels (0, 1.0, 1.5, 2.0 %) and four levels of zinc (0, 20, 30, 40 ppm). Result show that Nitrogen 1.5 % significantly increased dry weight of curd, compactness of curd and colour of curd. Whereas, maximum total soluble solids in curds was recorded in nitrogen 2.0 %. Zinc had also significant effect on dry weight of curd, compactness of curd and colour of curd. The double foliar spray (30 and 45 DAT) of 1.5 per cent nitrogen and 40 ppm zinc individually found to be best for yield and growth parameter.
