Effect of zinc on growth, yield and quality of okra [Abelmoschus esculentus (L.) Moench]

Abstract

A field experiment was conducted to study the “Effect of Zinc on Growth, Yield and Quality of okra [Abelmoschus esculentus (L.) Moench]” at Horticulture farm, S.K.N. College of Agriculture, Jobner. The experiment consisted of four zinc levels (control, 2.5 kg/ha, 5.0 kg/ha and 7.5 kg/ha) in Randomized Block Design with three replications. Results indicated that soil application of 7.5 kg zinc per ha. significantly enhanced the plant height (118.23 cm), number of branches per plant (2.58), leaf area (116.80 cm), chlorophyll content (1.60 mg/g), fruit length (11.70 cm), number of fruit per plant (22.33), fruit yield per plant (233.67 g), per plot (5.61 kg), per hectare (129.81 q), protein (1.40%) and crude fiber content in fruits (1.40 %), net return (252360 Rs) and B: C ratio (4.43) also proved at par However application of 5.0 kg zinc per ha also proved at par with all parameters.
