Production and quality of some edamame varietiesas affected by residual effect of worm compost application

Abstract

Edamame is a kind of soybean which is consumed as green vegetable. It is harvested when its pod is still fresh green colour at 58-65 days after cropping. This research aimed to evaluate production and quality of some edamame varieties as affected by residual effect of worm compost application. The research carried out at Mangli Village, Kaliwates, Jember, East Java on an irrigated field that has been used previously for research concerning utilizing of worm compost (Treatment-I). The research was designed factorial in complete randomized block consisted of two factors of treatment with three replications. The first factor was variety of edamame (V), includes: R75 (V1), R75/F2 (V2) and R76 (V3). The second factor was combination between worm compost and inorganic fertilizer, includes 100% N inorganic (C0), 50% N inorganic + 50% N worm compost (C1), 25% N inorganic +75 N worm compost (C2), and 100% N worm compost. (C3). The observed variables were crops growth components (crops height, number of productive branch and internodes), yield components (the weight of raw matter and export matter grades, pod size, fibre content, vitamin C and sugar content). The result indicated that there was interaction effect between varieties and worms compost on to weight of raw matter yield. Variety of R75 fertilized with doses of 75% worm compost and variety of R76 fertilized with 100% worm compost gave the best result for raw matter grade weight.
