Growth and yield of five Indonesian new superior varieties of soybean in dry climate rainfed rice fields

Abstract

Indonesian new superior varieties of soybean are continually released as an effort to increase soybean productivity. Some new superior varieties such as Devon 1, Dena 1, and Dega 1 were not widely known by the stakeholders. This research aims were to investigated the growth and yield of five Indonesian new superior varieties of soybean in the dry climate rice field. The experiment was conducted from March to July 2018 in Segala Anyar Village of Central Lombok Regency, West Nusa Tenggara Province, Indonesia. The experimental design was used non-factorial randomized block design with the soybean varieties as treatments (Devon 1, Dena 1, Anjasmoro, Argomulyo, and Dega 1). Each treatment was repeated four times. The parameters observed included plant height, number of branches, number of leaves, number of sections, number of pods, and soybean production. Data were collected from 10 crop samples for each replication during vegetative phase 1 and 2. The results showed that the soybean varieties had a significant effect on plant height, number of branches, number of sections and production. The crop could not produce optimally during field experiment due to lack of water in the pod-filling phase. Generally, it could grow well and has ability to produce yield.
