Effect of organic and chemical fertilizers on the growth and production of soybean (Glycine max) in dry land

Soybean is known for its high protein content, which the reason why it widely used as one of main food sources humans and animals. In order to optimize soybean growth, farmers tend add excessive dosage chemical fertilizer this crop. Furthermore, a continuous application without organic addition may cause rapid depletion nutrients in soil. This study aimed evaluate effectiveness treatment reduce amount urea needed cultivation. A complete randomized design was conducted using 21 treatments triplicate with 4x3 m plot size. Analysis variance carried out compare means measurement data Duncan multiple range test (DMRT 5%) applied. The 2,000 kg ha-1 compost + 50 (O2K2A1) resulted highest dry yield had significant differences urea-only treatment. mixture fertilizers no result over compared use only. Compost 1,000-2,000 50-100 (O2K2A1 O 2K1A2) showed an increase seed 35-38 % profit reaching 333-340 USD standard ha -1 SP-36 KCl (O0K0A1).
