Arbuscular Mycorrhiza inoculation for Increasing the Tolerance Index and Productivity of Soybean on Marginal Soils

Abstract An efforts to increase soybean crop productivity are highly related of nutrients availability and crops management. This research was conducted investigate the plant tolerance index (TI) mycorrhizae role P in a dry land. Factorial randomized block design that consists mycorrhizal factors (0, 5, 10 15 g inoculant per plant) cultivars (Anjasmoro, Dering 1 Grobogan) repeated three times. The results showed inoculation with dose able root length, volume, weights, grain number weight 100 grains. highest grains obtained by_ cultivar. In addition higher weigh resulted by Grobogan anjasmoro cultivar adaptability increased_ on marginal soils Further more gave nonsignificant effect TI (1,97) _by dering cultivars. These confirmes usage −1 inoculants chould be applied for increasing growth
