    Abstract

    The aims of this research were to (1) know correlation between kind and dosage of fertilizier which applied by farmer with the achieved rice productivity (2) know status soil availability of N total, P available, and K available (3) know correlation between kind and dosage of fertilizier applied with the content of N total, P available, and K available (4) know correlation between soil availability of N total, P available, and K available with the achieved rice productivity. This is the explorative and correlative research, the approach of this research was by direct observation on the location and supported with laboratory analyze to determine the content of N total, P available, and K available on soil then connected kind and dosage of fertilizer with rice productivity and the content of N total, P available, and K available on soil. The act of determining sample point based on variation of fertilizing (kind and dosage of fertilizer) at each Map Soil Unit (SPT). Fertilizing and rice productivity data was obtained from the result of interview with farmer. While data content of N total, P available, and K available obtained from the result of laboratory analyze. Kind of fertilizer applied by Jatisrono farmer were urea, SP-36, KCl, ZA, phonska and organic fertilizer. The result of this research showed that kind and dosage of fertilizer which see applied by Jatisrono farmer were non significant correlated with rice productivity although the content of N total, P available, and K available on soil. Rice productivity in District Jatisrono revolve from 4.000 kg/ha to 6.667 kg/ha with average productivity in the amount of 5.500 kg/ha. The content of N total ranges from low (0,029 %) to medium (0,412 %). The content of P available ranges from very low (9,33 ppm) to very high (70,75 ppm). The content of P available on soil ranges from very low (0,08 me/100g) to medium (0,26 me/100g). Keys word : Correlation, Kind and Dosage of Fertilizer, Rice Productivity, Content of N total, P available, and K available
