Abstract

ABSTRACT Combination between Rhizobium and sodium have been interacting effect to production of rice bean seed dry weight. Rhizobium 15 g/kg seeds are more suitable dose for rice been. The effect of sodium to rice bean by growth decline gradually beginning from 0.5 g/kg seed in the soil. Net assimilation rate, mean relative growth rate and seed production was suppressed if high sodium concentration applied in the soil. However under dose of 0.5 g/l sodium was precisely utilized for growth of rice bean, because in low sodium concentration in the soil could replace potassium ion. Application of rhizobium 15 g/kg seed and sodium 0.5 g/l could cause nitrogen necessity efficiency to 136 % and is recommended for optimal plant growth.
