Effect of Moringa Leaf Extract and its Solution Application Forms on Growth and Yield of Okra

Abstract

An experiment “Effect of Moringa leaf extract and its solution application forms on growth and yield of okra” was carried out at Agriculture Research Institute North Mingora, Khyber Pakhtunkhwa, Pakistan in the year 2019. Current study was consisted of two factors and was carried out in Randomized Complete Block Design (RCBD) with three replications. Factor ‘A’ was solution application forms i.e. fresh Moringa leaf extract solution and dry Moringa leaf powder solution, while Factor B was Moringa leaf extract levels (0, 2, 4, 6, and 8%). Different forms of Moringa leaf extract solution and levels positively affected growth and yield of okra. The maximum plant height (226.1cm), flowers plant-1 (34.5), number of fruit pickings (28.3), pod length (9.5 cm), pod diameter (14.6 mm), individual pod weight (11.3 g), pods plant-1 (34.5), yield ha-1 (14.6 tons) were noted with dry Moringa powder extract solution. Among different levels of Moringa leaf extract solution, the maximum flowers plant-1 (36.3), pods plant-1 (36.3), pod length (11.0 cm), pod diameter (15.8 mm), individual pod weight (12.0 g) and yield ha-1 (16.4 tons) were recorded with 6% of Moringa leaf extract solution, while increased plant height (242.0 cm), number of pods pickings (29.8), and days to first pod picking (50.0) were recorded with 8% of Moringa leaf extract solution. It is recommended that dry Moringa leaf powder solution at 6% may be used to improve the growth and yield of okra crop under Swat climate.
