EFFECTS OF SOIL-APPIED ORGANIC FERTILIZER COMBINED WITH FOLIAR ORGANIC FERTILIZER ON GROWTH AND YIELD OF OKRA

Abstract

This study was conducted to evaluate the effect of soil-applied organic fertilizer and foliar organic fertilizer on growth and yield of okra in Gia Lam district, Ha Noi city. The two-factor experiment was carried out in a randomized complete block design with three replications. The soil-applied organic fertilizer was microbial organic fertilizer (G1), chicken manure (G2) and vermicompost (G3). The foliar organic fertilizer was fish emulsion (L1) and seaweed (L2). The results showed that microbial organic fertilizer and vermicompost improved growth, physical traits, and consequentlly increased okra yield compared to chicken manure. Using foliar application of seaweed was higher growth and yield of okra than fish emulsion. The combined use of microbial organic fertilizer or vermicompost and seaweed showed the highest okra yield.
