摘要：Sorghum is a commodity which is expected to be an alternative food source to reduce the need for national rice. This plant has great potential to be developed in Indonesia because it has a large area of adaptation, including on degraded dry land. This study aims to analyse the growth and production of sorghum plants and changes in chemical soil properties due to the treatment of mulch and organic fertilizer in the first planting period. The study design uses a Split Plot Design, which the Main-Plots is mulching, consist of M0: None mulch, and M1: Straw mulch; Sub-Plot (organic fertilizer) consisting of: B0: None organic fertilizer (0 ton ha-1), B1: Cow manure (25 ton ha-1), B2: Compost (25 ton ha-1), B3: Cow manure (12.5 tons ha-1) + compost (12.5 tons ha-1). This study finding that organic fertilizer significantly increased vegetative and yield of sorghum. In addition, cultivating sorghum either without mulching or by applying mulch and organic fertilizers can improve soil chemical properties in dry land.
