Influence of humic acid and fulvic acid on growth and yield of Okra

Abstract

A study was undertaken to identify the nutrient management practice and levels of humic and fulvic acids with appropriate concentration for better plant growth and yield of Okra. The experiment was laid out in split-split design with three nutrient management practices, three sub treatment of humic acid (0, 0.25 and 0.50%) and sub-sub treatment of fulvic acid (0, 0.10 and 0.25%) at college of Horticulture, Bagalkot. Observations on crop growth and yield parameters were recorded. It was found that among the nutrient management practices and foliar application of humic and fulvic acid significantly increases the growth and yield of okra. The maximum plant height (123.43 cm), number of leaves (35.38), number of branches per plant (2.55), drymatter production (485.43 kg ha-1), number of fruits per plant (24.27), fruit length (14.94 cm), fruit weight per plant (314.62 g / plant) and fruit yield (111.12 q ha-1) recorded under recommended nutrient practice and foliar application of humic acid @ 0.50 per cent and fulvic acid @0.25 per cent.
