Response of Okra to Zinc and Boron Micronutrients

Results of the field experiment conducted at Research Farm, CCS Haryana Agricultural University, Hisar during rainy season of 2006 and 2007 revealed that the soil application of zinc sulphate and borax along with recommended dose of N PK as basal dose before sowing significantly influenced all the plant characters. Plant height, number of branches, fruit length, fruit diameter, average fruit weight and fruit yield were maximum with treatment combination of zinc sulphate 40 kg/ha and borax 15 kg/ha. Similarly, the protein content of okra [Abelmoschus esculentus (L.) Moench] fruits also increased with the increased level of zinc sulphate and borax being maximum with the highest level of zinc sulphate (40 kg/ha) and borax (15 kg/ha) applied in soil independently and in combination. Combination of zinc sulphate (30 kg/ha) and borax (15 kg/ha) increased the contents of chlorophyll ‘a ’, chlorophyll ‘b ’and total chlorophyll to their maximum.
