Effect of foliar spray of micronutrients on yield of cauliflower (Brassica oleracea L. var. Botrytis)

Abstract

The experiment was conducted during rabi, 2016-2017 at Regional Horticultural Research Station, Navsari Agricultural University, Navsari, Gujarat, India to evaluate the Effect of foliar spray of Micronutrients on Yield of Cauliflower (Brassica oleracea L. var. Botrytis). The experiment was arranged over 9 treatments comprising, micronutrient sources T1: Ammonium molybdate (0.1%), T2: Boric acid (0.2%), T3: Zinc sulphate (0.5%), T4: Copper sulphate (0.5%), T5: Ferrous sulphate (0.5%), T6: Manganese sulphate (0.5%), T7: 1% General grade-1 (Fe-2.0, Mn-0.5, Zn-4.0, Cu-0.3, B-0.5), T8: 1% General grade-1 + T1 and T9: control which was laid out in a Randomized Block Design with three replications. The application of 1% General grade-1 + T1 had shown significant impact on yield parameters viz. marketable curd yield per plot (37.11 kg), marketable curd yield per hectare (28.64 t), curd diameter (19.16 cm), Gross weight of curd (2.65 kg/plant) and Net weight of curd (883.33 g/plant).
