Analysis of prospects application of integrated farming system models for lowland rice with beef cattle to strengthen farmers’ economy in West Sumatera

Abstract. Crop-Livestock-System (CLS) is an agricultural system approach that can improve business efficiency, maintain land fertility and realize sustainable agriculture, especially on small-scale agriculture. This research was conducted in Gunung Talang Subdistrict, Solok Regency, West Sumatra, aimed to find out the habits of farmers and the potential to integrate and calculate farmers' income if they only do one commodity farming, namely rice, or rice and cattle. Data collection was conducted from June to August 2018 using survey methods. Data collection was carried out through interviews with 30 lowland rice farmers as respondents, randomly selected. Data collected includes crop and livestock farming data such as: farmer characteristics, average rice field area, average productivity and production value, average number and value of inputs (seeds, inorganic fertilizers and organic fertilizers, and organic and inorganic pesticides, the average supply of laboratory in an integrated farming system between plants and cattle. The results showed that average rice yield was 5.74 tons/ha of dried ground rice. The use of inorganic fertilizer urea 100 kg/ha (N 71.43%), SP-36 50 kg/ha (50%), KCl 50 kg/ha (50%).The income of farmers with only rice IDR 11,816,807 for ones hectare land. Total income from paddy (1 ha) and livestock (2 heads) integrated farming system about IDR 17, 612,405/season and provide R/C value about 1.44, meanwhile R/C value of non integrated farming system about 1.33. It means, paddy and livestock integrated farming system could increase farmer’s income about 49,45% per season compared to non integrated farming.
