Abstract

Agriculture, IGKV, Raipur (C.G)” to find out the possible effect of foliar application of micronutrients with different concentration levels on growth and yield of broccoli. Three replications of the experiment were set up using a completely randomized design (CRD). It was consisted of ten treatments including T0: Control (without spray of micronutrients), T1: Cu @ 0.20%, T2: Cu @ 0.40%, T3: Cu @ 0.60%, T4: Bo @ 0.20%, T5: Bo @ 0.40%, T6: Bo @ 0.60%, T7: Zn @ 0.20%, T8: Zn @ 0.40% and T9: Zn @ 0.60%,”. Three foliar applications were performed at 15, 30 and 45 days after transplanting. The experiment's findings revealed a considerable difference between different treatment combinations. Treatments T9 -zinc sulphate @ 0.60% found highly effective for growth parameters as it showed greatest plant height (66.81cm), no. of leaves (26.47), stalk length (18.22 cm), root length (16.06 cm) while T5- boric acid @ 0.40% was found superior to days to first curd induction, 50% maturity and harvest of curd. Foliar application of micronutrients has become a farm management practices which increases the overall characters of various crops. The aim of this experiment was to evaluate the effect of foliar application of individual nutrients on growth and yield of broccoli. It may be concluded that foliar application of zinc sulphate @ 0.60% showed a positive response and gives highest effect for growth parameters and boric acid @ 0.40% resulted in increased yield attributing parameters. Therefore, foliar micronutrient the absorption may be a potential strategy to maximize broccoli growth and output.

Conclusion

The current experimental findings suggest that sprays of different micronutrients (Cu, B, Zn) give effective response in growth, yield and quality in broccoli. The finding revealed that T9- zinc sulphate @ 0.60% was found better for increasing vegetative parameters whereas T5- Boric acid @ 0.40% were found better performance in yield parameters.
