Impact of micronutrients spray on growth and yield of Brassica oleracea var. Capitata

Abstract

The experiment was conducted during rabi, 2016-2017 at Regional Horticultural Research Station, Navsari Agricultural University, Navsari, Gujarat, India to evaluate the impact of micronutrients spray on growth and yield of Brassica oleracea var. capitata. The experiment was arranged over 9 treatments 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 (28.54 cm), length of stalk (11.36cm), number of wrapper leaves per plant (42.26), number of non wrapper leaves per plant (21.93) and plant spread (N-S: 55.96 cm & E-W: 54.22 cm) at harvest. Highest yield of head per plot (31.42 kg) marketable head yield per hectare (24.24 t) and other yield attributes viz., polar diameter of head (15.46 cm), equatorial diameter of head (13.35 cm), gross weight of head (1.24 kg/plant) and net weight of head (748.00 g/plant) were recorded significantly highest in T8 (1% General grade-1 + T1) treatment. While days of first head initiation, days to first marketable head and head compactness did not show any significant differences.
