Abstract

Penelitian dilaksanakan di lahan sawah Desa Tanjung Mulia, Kecamatan Tanjung Morawa, Kabupaten Deli Serdang, dimulai dari bulan Mei hingga September 2017 dengan menggunakan metode rancangan acak lengkap faktorial dengan 2 faktor, yaitu faktor pertama jumlah bibit (1 bibit, 2 bibit, 3 bibit) dan faktor kedua populasi tanaman berdasarkan modifikasi sistem tanam jajar legowo (sistem tanam konvensional dengan jarak tanam 30cm x 30cm populasi 35 rumpun per plot, sistem tanam jajar legowo 4:1 dengan jarak tanam 20cm x 20cm populasi 60 rumpun per plot, sistem tanam jajar legowo dengan jarak tanam 10cm x 20cm populasi 114 rumpun per plot, sistem tanam jajar legowo dengan jarak tanam 10cm x 20cm dan disisipi tanaman setiap 10 cm populasi 154 rumpun per plot, sistem tanam jajar legowo dengan jarak tanam 10cm x 10cm populasi 190 rumpun per plot). Luas lahan yang digunakan sebesar 15915,2cm, dengan total plot sebanyak 45 plot, masing-masing plot berukuran 2cm x 1,5cm. Hasil penelitian menunjukkan bahwa penggunaan 1 bibit per rumpun dengan sistem tanam jajar legowo dengan jarak tanam 20cm x 20cm populasi 60 rumpun per plot memberikan pengaruh nyata dalam peningkatan produksi padi sawah. Interaksi antara faktor jumlah bibit dan populasi tanaman secara nyata meningkatkan tinggi tanaman tetapi tidak meningkatkan produksi padi sawah (Oryza sativa L.).

Abstract

Inceptisol is a widely enough soil and has many obstacles to use as agricultural field, some of the constraints are; Low level of the organic content, soil acidity, high level of Al saturation and low CEC hance this land cause a lower productivity. increasing its productivity by giving organic material compost which is durian skin compost and SP36 fertilizer.This research is aimed to know the change of some chemical properties of Inceptisol soil and growth of corn plant (Zea mays L.) due to composting of durian skin and SP36 fertilizer. This study was conducted by using Randomized Block Design (RBDs) method with two replications consisting of thirty two treatments. The treatments divided in two addition fertilizer durian skin compost (B) and SP36 (P) fertilizer consisting of; 0 g / polybag (B0), 12.5 g / polybag (B1), 25 g / polybag (B2), 37.5 g / polybag (B3), 0 g / polybag (P0), 0,25 g / polybag (P1), 0,50 g / polybag (P2), 0.75 g / polybag (P3), and their interactions. The results showed that durian skin compost significantly affected the carbon content on soil, and SP36 fertilizer had significant effect on soil P level, and both interaction had significant effect on the height of plant.
