Pengaruh Pemberian Biochar dari Berbagai Sumber dan Pupuk Kandang Sapi Terhadap Pertumbuhan dan Produksi Tanaman Padi Sawah (Oryza sativa L)

Abstract

This research was conducted in XXV Hamlet, Sampali, Percut Sei Tuan, Deli Serdang Regency with a height of 6 meters above sea level (asl), from September to January 2019.The study used Factorial Randomized Block Design (RBD) consisting of 2 treatment factors, namely: 1) Factors giving various biochar sources (notation B) consisting of 4 levels of treatment, namely: B0 = control (not using biochar); B1 = rice husk biochar dose of 10 tons/ ha (4 kg/ plot); B2 = jyringa skin biochar dose of 10 tons/ ha (4 kg/ plot); B3 = control of rubber seed shell biochar dosage of 10 tons/ ha (4 kg/ plot), 2) Factor for giving cow manure (P notation) which consists of 4 levels of treatment, namely: P0 = control (not using cow manure); P1 = cow manure dose of 5 tons/ ha (2 kg/ plot); P2 = cow manure dose of 10 tons/ ha (4 kg/ plot); P3 = cow manure dose of 15 tons/ ha (6 kg/ plot); each treatment was repeated 2 (two) times.The parameters observed consisted of plant height, number of tillers, panicle number per sample plant, weight of grain production per sample, weight of grain production per plot and weight of 1000 grain per plot. The results obtained from this study are: 1) Giving biochar from various sources significantly affected plant height, number of tillers, number of panicles per plant sample, weight of grain production per sample, weight of grain production per plot and weight of 1000 grains of grain. In this case it was found that the administration of biochar from rice husk was the best type of biochar in supporting the growth and production of rice plants; 2) Provision of cow manure does not affect the growth and production of rice plants; and 3) The combination of giving biochar from various sources and cow manure does not affect the growth and production of rice plants.
