Land Suitability and Upland Rice Productivity with Integrated Crop Management in Sorong Regency

Abstract

With Integrated Crop Management, the study is aimed at improving the production of upland rice in West Papua (ICM). On-farm research and land surveys were used to conduct this study. We looked at the following factors: 1) the suitability of the rice field in Sorong Regency, 2) the growth and production of rice plants, and 3) the social and economic factors affecting farmers. The findings indicate that upland rice development is feasible on dry land, over an area of 317,831 ha, which is made up of three types of suitable land: very suitable land (S1), which covers an area of 61,684 ha; quite a suitable land (S2), which covers an area of 59.021 ha with land constraints in the form of nutrient retention (nr); and suitable marginal land (S3), which covers an area of 197.126 ha with constraints in the form of (eh). Dry-milled grain yields in the ICM pattern with the Situ Bagendit and Batutegi varieties were 4.48 t/ha and 4.16 t/ha, respectively, greater than those in the farmer pattern. The ICM pattern has a higher profit of IDR 5,360 compared to the farmer pattern of IDR 2,400 with a B/C value of 1.6 and 1.2.
