Rice production in North Aceh Regency based on N, P, K and C-organic studies

Abstract

Rice is the staple food for most of Indonesia’s population. Efforts to increase rice production and productivity are really carried out with agricultural intensification and extensification. However, rice production and productivity did not increase significantly. This research was conducted to find out the nutrient content of N, P, K and C-organic in some irrigation area in North Aceh. The study was conducted in four irrigation areas in North Aceh, namely Krueng Sawang irrigation, Krueng Pase Irrigation and Krueng Langkahan Irrigation. The method used in this research survey method. Determination of respondents is using purposive sampling method. Observations made on observed soil chemical properties include N-Total, P-available, K-exchangeable, and C-organic soils. The farm business data is only the yield per harvest. The results showed that the soil C-organic content ranged from 1.61 to 5.18%, with low to very high criteria. N-total levels ranged from 0.17 to 0.55% with low to high criteria. P-available levels ranged from 1.87 to 6.85 ppm with very low to low criteria, Then, K-exchangeable content ranged from 0.29 – 0.96 ppm with low to high criteria. The yield per harvest ranges from 4.45 to 6.00 t/ha.
