Pengaruh Biochar Sekam Padi dan POC NASA Terhadap Pertumbuhan Dan Hasil Tanaman Lobak Merah (Raphanus sativus L.) Pada Tanah Alluvial di Polybag

Abstrak

This study aims to determine the effect of the interaction of rice husk biochar and NASA POC on the growth and yield of red radish (Raphanus sativus L.) on alluvial soil in polybags. This research was conducted at Our Lady of Jeruju Parish, Jalan KomYos Soedarso, Kec. West Pontianak, Pontianak City, West Kalimantan. The method used in this study was a completely randomized design (CRD) consisting of two factors. The first factor is Biochar rice husk with code (B) of 3 levels, namely: b1=20 gram/polybag, b2= 40 gram/polybag, b3=60 gram/polybag. The second factor is NASA Liquid Organic Fertilizer with code (N) in 3 levels with concentrations: n1 = 2ml/liter of water, n2= 4ml/liter of water, n3= 6ml/liter of water. Each treatment was repeated 3 times and each repetition consisted of 3 plants. The results showed that there was an interaction between rice husk biochar and NASA POC which had a very significant effect on plant height, tuber weight and had a significant effect on tuber diameter. However, it had no significant effect on the number of leaves and tuber length of red radish plants. The highest yield for the average plant height was found in b3n3 (60 gram rice husk biochar/polybag & NASA POC 6ml/liter of water), namely 36.83 cm. The highest yield on the average number of leaves was found in b2n1 (40 gram rice husk biochar/polybag & NASA POC 2ml/liter of water), namely 19.89 strands. The highest yield on the average tuber length was found in b1n2 (20 gram rice husk biochar/polybag & 4ml/liter of water) which was 14.27 cm. the highest yield on average tuber diameter was found in b1n3 (20 gram rice husk biochar/polybag & NASA POC 6ml/liter of water) which was 5.17 cm and the highest yield on average tuber weight was found in b1n3 (20 gram rice husk biochar /polybag & 6ml/liter of water) which is 177.00 grams
