Effect of different micronutrients on growth and yield of cauliflower (Brassica oleracea var. botrytis L.) cv. Pusa Sharad

Abstract

A Field experiment was conducted to evaluate the effect of different micronutrients on growth and yield of cauliflower. The whole research experiment was carried out for two years (i.e., rabi season 2017-18 and 2018-19 at Research cum Instructional farm of Horticulture, Department of Vegetable Science, IGKV, Raipur. The experiment was laid down under randomized block design in three replication, and consisting of fifteen treatments. The important growth parameters and curd yield encompassed in the study were plant height (cm), number of leaves plant-1, width of leaves (cm), length of leaves (cm),length of root (cm), stem length (cm), stem diameter (cm), days to first curd initiation, days of 50% curd maturity and curd yield (q ha-1). The experimental findings revealed that almost all the treatments showed a positive effect on growth and yield, however treatment T5 (100% RDF + Borax @ 20 kg ha-1 + Ammonium molybdate @ 2 kg ha-1 + ZnSO4 @ 25 kg ha-1) exhibited most significant influence on all above mentioned parameters when compared to T1- Control (100% RDF). Therefore, on the basis of experimental it can be concluded that the application of micronutrients is an effective approach in cauliflower to enhance the growth, curd maturity and curd yield.
