Aplikasi Amelioran Jerami dan Sekam Padi pada Tanah Gambut terhadap Pertumbuhan dan Produksi Kedelai

Abstract

Research applications straw and rice husk as ameliorant on peat soil to improve the growth and production of
soybean in the peat soil was conducted from April to August 2012, at green house of the Faculty of Agriculture,
University of Islamic of Indragiri. The objective was to get the best composition application ameliorant straw and rice
husk on peat soil on the growth and production of soybean. The experiment was used the completely randomized design
with a single factor consisting of 8 treatments (control, 3 tons.ha -1 of AJP, 3 tons.ha-1 of ASP, 3 tons.ha-1 of KJP, 2 tons.ha-
1 of KJP + 1 tons.ha-1 of AJP, 2 tons.ha-1 of KJP + 1 tons.ha-1 of ASP, 1 tons.ha-1 of KJP + 1 tons.ha-1 of AJP and 1 tons.ha-
1 of KJP + 1 tons.ha-1 of ASP) with 3 replications. Observations of each parameter analysis of variance (F test) and the
difference in treatment was continued with DNMRT (Duncan’s New Multiple Range Test) at 5% level. The results showed
granting ameliorant 3 tons.ha-1 of AJP can improve plant growth in terms of height that 51.16% (145.75 cm), ratio of the
root crown (4.86 g) dry stover weight of 1232.59% (24.12 g) soybean crop production, including number of 272.72% of
pods per plant, number of seeds per plant and seed weight 335.87% 333.23% dry. compared with no treatment.
