ABSTRACT
Sorghum (Sorghum bicolor L. Moench), is a strategic commodity as a staple food, feed and industrial raw materials. Even with good nutritional content, sorghum can replace rice. However, in Timor-Leste, planting has not been as intensive as staple food crops such as rice, corn and other popular food sources. Many technological innovations to produce high sorghum crop productivity have been produced such as using fertilizer and planting distance set. The research aims to investigate production potency of sorghum which cultivated with vary of level fermented organic fertilizer (FOF) and planting distance. The research was conducted at Titilari Lospalos Village, Lautem, East-Timor, starting from June to October 2022. The study was designed with a completely randomized design (CRD) factorial with 2 factors: Factor A was FOF consisting of 0 (A0), 6000(A1), 7000(A2), 9000(A3) kg/ha. The second factor was distance planting consisting of B1 (50x25), B2 (60x25), B3 (70x25), B4 (80x25) cm; there was 3 replications. The observed variables were: total leaves, height plant, biomass and seed production of sorghum. The results showed that the highest total leaves at A3 (72,87 leaves/plant) and significantly different (P<0,05) to A0, A1 A2. The highest height was at A3 (94,72 cm) significantly different with A0, A1, and A2. The highest biomass production was A3 (1,70 kg/plant) not different (P>0,05) with A2 but significantly different with A0 and A1. The highest seed production was A3 (0,60 kg/plant) no different to A2 but had significantly different to A0 and A1. Effect of planting distance showed that all variables had no significantly different. To conclude that effect of A3 had the highest values on total leaves, height plant, biomass and seed production. The biomass and seed production, was equivalent to 23,78 and 8,37 tons/ha therefore, sorghum has potency as staple food in East Timor.
