PENGARUH JERAMI PADI DAN RASIO PUPUK UREA, TSP, KCl TERHADAP PERTUMBUHAN DAN PRODUKSI KEDELAI ( Glycine max (L) Merril. )
Abstract: This research was
conducted to find out the effect of rice straw and ratio of Urea, TSP, KCL on
the growth and production of soybean. This research has been conducted in the
experimental farm, Faculty of Agriculture University of Riau, from January to
April 2016. This study used randomized block design (RAK), arrange in a
factorial with 2 factors, factors of rice straw mulch with 3 levels doses of 0
kg/Ha, 5 kg/Ha, 10 kg/Ha and factor ratio of Urea, TSP, KCL with 4 levels doses
of 0 kg/Ha, 25, 50, 50 kg/Ha, 50, 100, 100 kg/Ha, 75, 150, 150 kg/Ha, two
factors combined to obtain 12 combined treatment, for each treatment consisted
of three replications, in order to get 36 experimental units. The data were
analyzed by analysis of variance and significantly different continued with
Duncan New Multiple Range Test (DNMRT) at 5% level. Each experimental unit
consisted of 52 plants, only seven plants become sample. The parameters
measured were the number of the effectiveness root nodules per plant, the
growth rate of plants, weeds, number of pods per plant, pods percentage pithy,
dry seed weight/m2, and the weight of 100 seeds. Research data show that rice
straw dose of 10 ton/Ha and ratio of Urea, TSP, KCl doses of 50, 100, 100 kg/Ha
produces a dry seed weight of 2,69 tons/Ha, higher than without treatments is
1,3 tons/Ha.
