Effect of Integrated Nutrient Managementon Growth and Yield of Okra

Abstract

This study was carried out at Subarna Agro-Based Initiative’s (SABI) field, Noakhali, Bangladesh during the period of Rabi Season, 2018. The objectives of this study were to evaluate the growth and yield performances of okra in different types of organic fertilizers and to identify the possible fertilizer treatment which enhances both growth and yield of okra [Abelmoschus esculentus (L.) Monech] .BARI Okra-1 was taken for the study. A Randomized Complete Block Design (RCBD) was used and there were 4 treatments namely; Farm Yard Manure (T1), Vermi-Compost (T2), FYM + Vermi-Compost (T3) and Integrated Nutrient Management (T4) were replicated three times. Plant height (cm), number of leaves, total flower, total number of fruits, fruit length (cm) and fruit weight (g) data were taken as parameters on the growth and yield of the plant. Though fruit weight was observed higher for the effect of T3 (72.78 g) but in case of Integrated Nutrient Management (T4) the other characters such as plant height, number of leaves, total flowers, total number of fruits, fruit length were observed higher. The T4 showed a comparatively better result of growth and yield than other treatments. This study clearly indicated that Integrated Nutrient Management which contains the micronutrients with minimum inorganic and organic manure may be a potential source for better growth and high yield in okra.

Dynamics of nutrient availability in okra production with organic and inorganic fertilizers

“…The maximum fruit weight was achieved by the application of FYM and vermicompost because of the increased nutrient uptake. Similar results were found by Mal et al (2013) [16] , Sachan et al (2017) [27] , Miah et al (2020) [20] and Narwariya et al (2023) [21] . The length and diameter of fruit were also influenced by application of organic manures with inorganic fertilizers.…”

Effect of Integrated Nutrient Management on Okra Production in Acid Soil

“…Organic matter incorporation has also been shown to have a substantial impact on carbon sequestration and retain mineral nutrients in soil [9]. Thus, in the tropics organic amendment plays a vital role on restoration degraded soil by enhancing sustainable soil health and forming complex with toxic substances [18].…”
