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.
