Abstract
ABSTRAK
Cara pemupukan dalam budidaya padi dilakukan sebagian besar petani di
Sragen dengan dosis seragam tanpa menghiraukan tingkat keragaman 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 April sampai Agustus 2015. Tahapan penelitian dikelompokan menjadi dua
kegiatan, yaitu pengumpulan data, 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 didominasi tinggi,
kemuadian 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 diatas dihasilkan rekomendasi pemupukan
yang sama, yaitu pemupukan N (Nitrogen) diberikan pada fase primordial saja,
dengan dosis 35 kg/ha. Sedangkan pupuk fospat (P) dan Kalium (K) tidak perlu
diberikan sama sekali selama pertumbuhan.
Kata kunci : padi, rekomendasi pemupukan, spesifik lokasi

ABSTRACT
THE MODIFICATION EFFECT OF “VRA” (Variable Rate Application)
FOR THE FIELD RICE FERTILIZATION USING “GLEDUR”
APPLICATOR
The fertilization method of rice cultivation was done by the majority of
farmers in Sragen with the equal variance of dose without considering the variety
levels in soil nutrient status which makes it not efficient. This study was aimed to
determine the dose recommendation and the N.P.K fertilizer application time for
each parcel of the fields. The study was conducted in Bener, Ngrampal, Sragen,
during the month of April to August 2015. The stage of this study was grouped
into two activities, there were data accumulation and VRA mapping. The result of
the study were (1) N-total content of laboratory test results for each 35 plots of the
location had the medium grade and 15 plots of the location had low grade. The
grade of P is high dominated. 31 plots of the location had K medium grade and 19
plots of the location had K high grade, (2) the results of the fertilizer
recommendation based on PUPS according to the eight status of nutrients above
had the same results of fertilizer recommendation, there were the N fertilizer was
applied only in pramodial phase with 35 kg/ha dose, while P and K did not need
to be applied at all over the growth.
Keywords: rice, fertilizer recommendation
