Efektivitas Pemberian Arang Sekam Padi dan POC Kotoran Sapi terhadap Pertumbuhan dan Produksi Tanaman Bawang Merah (Allium ascalonicum L.)

ABSTRACT
This research method uses a factorial randomized block design (RBD) consisting of 2 factors with 16 treatment combinations. The first factor is the provision of rice husk charcoal (O) which consists of 4 levels, namely.O0 = 0 g/planting hole, O1 = 50 g/planting hole, O2 = 100 g/planting hole, O3 = 150 g/planting hole. The second factor is the provision of cow dung POC (M) which consists of 4 levels, namely.M0 = 0 ml/planting hole, M1 = 50 ml/planting hole, M2 = 100 ml/planting hole, M3 = 150 ml/planting hole. Parameters observed were number of leaves (strands), number of tillers (saplings), tuber diameter (mm), dry tuber production per sample (g) and dry tuber production per plot (g). The results showed that the administration of rice husk charcoal had a very significant effect on the parameters of the number of leaves (strands), number of tillers (saplings), tuber diameter (mm), dry tuber production per sample (g) and dry tuber production per plot (g). Where is the best treatment at O3 = (150 g/planting hole). Giving cow dung POC had no significant effect on the parameters of number of leaves (strands), number of tillers (saplings), tuber diameter (mm), dry tuber production per sample (g) and dry tuber production per plot (g). The interaction between giving rice husk charcoal and cow dung POC had no significant effect on the parameters, namely the number of leaves (strands), number of tillers (tillers), tuber diameter (mm), dry tuber production per sample (g) and dry tuber production per plot (g).
