Penelitian dilakukan di rumah kaca bertujuan untuk mengetahui pengaruh pemberian pupuk NPK compaction DGW terhadap pertumbuhan dan produksi padi sawah. Penelitian menggunakan rancangan percobaan Rancangan Acak Lengkap (RAL) pola Faktorial AxB di mana faktor A adalah dosis pupuk NPK Compaction DGW yang terdiri dari 4 taraf dosis (A1= 0 kg/ha; A2 = 100 kg/ha; A3 = 200 kg/ha; A4 = 300 kg/ha) dan faktor B adalah ukuran butir pupuk yang terdiri atas 2 taraf (B1 = > 1 mm; B2 = < 1 mm). Diulang tiga kali, sehingga terdapat 24 pot percobaan. Variabel yang diamati adalah: tinggi dan produksi tanaman padi. Hasil analisis statistik dari delapan kombinasi perlakuan yang diteliti menunjukkan bahwa tidak terdapat perbedaan yang nyata dari semua perlakuan. Tetapi terdapat kecenderungan perbedaan tinggi tanaman dan produksi tanaman padi pada perlakuan yang diujikan. Dosis dan ukuran butir pupuk yang sesuai terdapat pada pelakuan A2B2. Hasil penelitian juga memberikan petunjuk bahwa pemberian pupuk NPK Compaction DGW yang dihaluskan memberikan hasil yang lebih tinggi dibandingkan tidak dihaluskan sebesar 33,48 %.
The research was conducted in a greenhouse with the aim of determining the effect of NPK compaction DGW fertilizer on the growth and production of paddy fields. The research used a Completely Randomized Design (CRD) experimental design with the AxB Factorial pattern where factor A is the fertilizer dose of NPK Compaction DGW fertilizer consisting of 4 dose levels (A1 = 0 kg / ha; A2 = 100 kg / ha; A3 = 200 kg / ha; A4 = 300 kg / ha) and factor B is the size of the fertilizer grains consisting of 2 levels (B1 = > 1 mm; B2 = < 1 mm). Repeated three times, so there were 24 experimental pots. The variables observed were: height and production of rice plants. The results of statistical analysis of the eight treatment combinations studied showed that there were no significant differences between all treatments. However, there was a tendency for differences in plant height and rice production in the treatments tested. The appropriate dose and size of fertilizer grains can be found in the A2B2 implementation. The results of the research also provide indications that applying finely ground NPK Compaction DGW fertilizer gives higher results than not grinding it by 33.48%.
