Effect of foliar spray of micronutrients on growth and 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. The experiment was arranged over 9 treatments comprising, micronutrient sources 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 growth parameters viz. plant height (74.93 cm), Length of stalk (16.59 cm), Number of leaves per plant (23.39) and Plant spread (N-S: 76.81 cm & E-W: 77.79 cm) at harvest. Highest marketable curd yield per plot (37.11 kg), marketable curd yield per hectare (28.64 t) and other yield attributes viz. curd diameter (19.16 cm), Gross weight of curd (2.65 kg/plant) and Net weight of curd (883.33 g/plant) were recorded significantly highest in T8 treatment. While days of first curd initiation and days to first marketable curd did not show any significant differences.
