Rice is the main food needs for the community in Indonesian. Fertilization is one of the activities is
very important in increasing the production of rice plant. This research aims to study the influence of
granting demand fertilizer plant and soil nutrient indexes against the growth of vegetative rice plant.
This research was carried out in lawland district Medan Baru at the points of coordinates 3.331810 LU
and 98.385300 BT from August until December 2016. The experimental design used completely
randomized design with two factor. The first factor was the provision of urea, sp36, kcl, and dolomit.
P1= 121,36 gram/plot, P2= 161,82 gram/plot, P3=202,27 gram/plot, P4= 242,73 gram/plot and the
second factor was based on soil nutrient index B1= 0,8 (dose less 20), B2= 0,9 (dose less 10%) B3= 1
(100% standart nutrient index), B4= 1,1 (dose plus 10%), B5= 1,2 (dose plus 20) were repeaed twice.
The result of experiment showed that P2B1 =129,45 gram/plot the best combination of the application
of fertilizers and soil nutrient index P4= 242, 72 gram/plot was the best fertilizer dose treatment
B2=0,9 (dose less 10%) was treatment of soil nutrient index.
Beras merupakan kebutuhan pangan yang utama bagi masyarakat di Indonesia. Pemupukan merupakan salah satu kegiatan yang sangat penting dalam meningkatkan produksi tanaman padi.Penelitian ini bertujuan untuk mempelajari pengaruh pemberian pupuk sesuai kebutuhan tanaman dan indeks hara tanah terhadap pertumbuhan vegetatif tanaman padi. Penelitian ini dilaksanakan di lahan sawah kecamatan medan baru pada titik koordinat 3.331810 LU dan 98.385300 BT dan dimulai pada bulan Agustus sampai dengan Desember 2016.Penelitian ini menggunakan rancangan acak lengkap dua faktor dengan faktor pertama berdasarkan pemberian pupuk Urea, SP36, KCl, dan DolomitP1 =121,36 gram/Plot, P2 =161,82 gram/Plot, P3 =202,27 gram/Plot, P4 =242,73 gram/plot dan faktor dua berdasarkan Indeks Hara Tanah B 1 =0,8 (dosis dikurang 20%), B2 =0,9 (dosisdikurang10%), B3 =1 (100% indeks hara standar), B4 =1,1 ( dosis ditambah 10%), B 5 =1,2(dosis di tambah 20%) yang diulang sebanyak 2 kali.Hasilpenelitian menunjukkan penerapan penerapan dosis pupuk dan indeks hara tanahkombinasi terbaik terdapat pada perlakuan P2B1, perlakuan dosis pupuk terbaik pada P4 =242,73 gram/plot dan perlakuan indeks hara tanah terdapat pada B2 =0,9(dosis dikurang10%).
