Abstract Applying fertilizer nitrogen (N) only when a crop response is predicted may enhance use efficiency and profitability while protecting the environment. The index at harvest (RI-harvest, ratio of maximum grain yield that plot in question) indicates actual to applied N, although it calculated after harvest. objective this study was predict RI-harvest wheat using normalized difference vege...

Pada daerah yang luas biasanya terdapat kesulitan dalam memantau fase tumbuh tanaman padi. Seiring dengan berkembangnya teknologi, salah satu alternatif dapat dilakukan untuk memperoleh data tersebut adalah menggunakan citra satelit. Fase padi diketahui menghitung indeks vegetasi berdasarkan tingkat kehijauan bantuan MODIS algoritma NDVI. Tujuan dari penelitian ini menentukan persamaan dan rent...
