Penerapan budidaya basah tanaman kedelai (Glycine max (L.) Merr) pada tanah sulfat masam

Abstract

Budidaya basah merupakan teknik agronomik yang dikehendaki untuk mencegah proses pemasaman pada tanah sulfat masam. Dengan latar belakang potensi dan peranan kedelai di masa mendatang dalam rangka meningkatkan gizi masyarakat serta untuk mengatasi sebagian dari kendala pertumbuhan dan hasil tanaman kedelai pada tanah sulfat masam maka dilakukan serangkaian percobaan di rumah kaca dan lapangan.

Wet cultivation is an agronomic technique applied to prevent acidification processes in acid sulfate soils. Considering the future potential and role of soybean in improving community nutrition, as well as to address constraints in growth and yield of soybean on acid sulfate soils, a series of greenhouse and field experiments were conducted. The greenhouse experiment employed a factorial design using a Completely Randomized Design (CRD). The first factor was cropping pattern, consisting of wet soybean–wet soybean (P1), lowland rice–wet soybean (P2), wet soybean–dry soybean (P3), and lowland rice–dry soybean (P4). The second factor was the level of lime application, consisting of four levels: 1/8 Potential Total Acidity (PTA) (K1), 2/8 PTA (K2), 3/8 PTA (K3), and 4/8 PTA (K4). The field experiment also used a factorial arrangement, structured in a Split Plot Design within a Randomized Block Design (RBD). These experiments aimed to evaluate the effectiveness of wet cultivation and liming levels in improving soybean growth and yield under acid sulfate soil conditions.
