Abstract

Soybean (Glycine max (L.) Merr.) is one of the best protein sources for Indonesians. However, the national soybean production does not meet the demand due to the low crop productivity, which causes major pests and poor soil nutrients. The best rate of N and P in promoting crop growth was investigated to get maximum yield, and minimize pod borer attacked by Etiela zinchenella on soybean c.v. Detam 1. The results showed that the interaction of N and P significantly affected the number of leaves, the number of pods produced, and the percentage of pod attached by pod borer. We concluded that the interaction between 25 kg.ha-1 Urea + 100 kg.ha-1 TSP showed the best growth, the highest yield, and the lowest percentage of pod attacked by pod borer
