Abstract
Fertilizing system of rice cultivation is done mostly big Farmers in Sragen with uniform dose, Regardless of the diversity of soil nutrient status, so that the process is not efficient. The study aims to determine recommended dose and time of fertilizer application of N, P, K to review every rice fields. Research was conducted in Bener, Ngrampal, Sragen Regency, On March until August 2014. Three Stages Being classified research activities, such as data collection,using a modified device of soil test (PUTS) Simulation Program, and Mapping VRA (Variable Rate Application). Produces Research (1) Search Google Articles Rice Soil Test Kit (PUTS).It was continued by analyzing of soil samples in the laboratory, it has been generated status of N, P and K in every sample point; (2) Article Search Google puppy simulation version 1.1. make a recommendation dose of fertilizer and time schedule each sample point; (3) By GPS and GIS were resulted VRA map, that is used to review determine by location right according to get fertilizer recommendation. Keywords: rice, fertilization recommendations PuTS Program, location specific ABSTRAK Sistem pemupukan dalam budidaya padi dilakukan sebagian besar petani di Sragen dengan dosis seragam tanpa menghiraukan tingkat keberagaman status hara tanah, sehingga tidak efisien. Penelitian bertujuan untuk menentukan rekomendasi takaran dan waktu aplikasi pupuk N, P, K untuk setiap persil lahan sawah petani. Penelitian lapangan dilakukan di Desa Bener, Ngrampal Kabupaten Sragen, pada bulan Maret sampai Agustus 2014. Tahapan penelitian dikelompokkan menjadi tiga kegiatan, yaitu pengumpulan data, simulasi dengan program PuPS, dan pemetaan VRA (Variable Rate Application). Penelitian menghasilkan (1) Kandungan N-total hasil uji laboratorium masing-masing 35 petak lokasi mempunyai harkat sedang dan 15 petak lokasi mempunyai harkat rendah. Harkat hara P di dominasi tinggi, kemudian 31 petak lokasi mempunyai harkat K sedang dan 19 petak lokasi mempunyai harkat K tinggi; (2) Rekomendasi pemupukan berdasarkan PuPS dari kedelapan status hara tersebut di atas dihasilkan rekomendasi pemupukan yang sama, yaitu pemupukan N (Nitrogen) diberikan pada fase primordia saja, dengan dosis 35 kg/ha apabila nilai BWD = 3,23 kg/ha apabila nilai BWD = 3,5 atau tidak perlu dipupuk N bila BWD = 4. Sedangkan pupuk fosfat (P) dan kalium (K) tidak perlu diberikan sama sekali selama masa pertumbuhan. Kata kunci: padi, rekomendasi pemupukan, program PuPS, spesifik lokasi
