The effect combination of organic and inorganic fertilizer on okra (Abelmoschus esculentus) growth

Abstract

Okra (Abelmoschus esculentus) is the most commonly and popular vegetables. The application of inorganic fertilizer is very important to increase the productivity of the crop, but overuse of inorganic fertilizer can lead to soil acidification that can affect the plant growth. The purpose of these study is to determine the effectiveness combination rate of organic and inorganic fertilizer toward okra growth and yield performance. This study was conducted in a greenhouse by using Randomized Complete Block Design (RCBD) with four replicates. The study was used chicken dung as organic fertilizer. The treatments applied were T0 (NPK), T1 (NPK + 20 g chicken dung), T2 (NPK + 40 g chicken dung), and T3 (NPK + 60 g chicken dung). NPK green was applied only one-time during 14 days after sowing (DAS) and was continued with NPK blue. T3 showed an increasing in fresh pod yield. Thus, combination of organic fertilizer and inorganic fertilizer was showed the positive effect to the crop production. The combination of organic and inorganic fertilizer was proven to be the most effective in okra production.
