. The potential of rainfed areas are quite large and productivity can be improved, among other things with a rational fertilization corresponding nutrient status of soil and crop needs for nutrients, and the use of high yielding varieties. The research aims to study the increase in the productivity of paddy fields with fertilization of N, P, K, and the use of high yielding varieties. The study was conducted in three locations, namely in Andong, Boyolali; Jakenan, Pati and Cibeber, Cianjur. Research using randomized complete block design with factorial pattern of incomplete treatment, 12 treatments and 3 replications. The treatment is a combination of fertilizer N, P, and K, plus a control treatment, and the treatments that are commonly used varieties of local farmers. The results showed that the limiting factors the growth of the rice plant rainfed areas in Jakenan, Pati, were organic-C, N, P, and K, Andong, Boyolali is organic-C, N and P, and Cibeber, Cianjur is N and K. The fertilization rational of N, P, and K for rainfed areas in Andong, Boyolali 300 kg urea, 75 kg and 50 kg KCl SP-36/ha, Jakenan, Pati 200 kg urea, 200 kg KCl and 50 kg of SP-36, Cibeber, Cianjur 250 kg urea, 50 kg of SP-36 and 50 kg KCl/ha. The use of high yielding varieties of rice have not been able to significantly increase the yield for rainfed areas compared with rice varieties that are commonly used by farmers.
