ANALISIS PERTUMBUHAN KEDELAI DI LAHAN KERING DENGAN APLIKASI Bradyrhizobium japonicum YANG DIINDUKSI GENISTEIN DAN PUPUK ORGANIK

Abstract: This study aimed to get the information of soybean growth response on inoculation of B. japonicum induced genistein under dry land. The experiment was conducted in farmer fields at Desa Sambirejo, Langkat on June-September 2012. The study used a factorial randomized block design with two factors and three replications. The first factor is genistein induction treatment consisting of without and genistein (50 μM). The second factor is the treatment of B. japonicum and organic fertilizer consisted of without B. japonicum; B. japonicum; B. japonicum + manure 10 t/ha; B. japonicum straw compost + 10 t/ha; B. japonicum + manure 5 t/ha + straw compost 5 t /ha. The variables observed are plant growth rate, plant growth relative and nett assimilation rate. The results showed that treatment of genistein (50 μM) decreased the plant growth rate 5-6 WAP, plant growth relative 5-6 WAP and nett assimilation rate . Treatment of B. japonicum + manure 5 t/ ha + straw compost 5 t/ ha tent to increase plant growth rate, plant growth relative and nett assimilation rate. The interaction between genistein induction and treatment B. japonicum + organic fertilizer tended to decrease plant growth rate, plant growth relative and nett assimilation rate.
