RESPON PERTUMBUHAN DAN PRODUKSI BAWANG PUTIH (Allium sativum L.) TERHADAP PEMBERIAN BOKASHI JERAMI PADI DAN PGPR PADA MEDIA TANAM

Abstract

Response of growth and production of garlic (Allium sativum L.) to the application of rice straw bokashi and PGPR on planting media. The purpose of the study was to determine the effect of giving rice straw bokashi and PGPR on the growth and production of garlic. This research was carried out in the experimental garden of the Faculty. Agriculture Sisingamngaraja XII Tapanuli University at an altitude of ± 1,400 m above sea level. Using Factorial Randomized Block Design (RAK) as the environmental design with two factors and 3 replications, namely the first factor: treatment with rice straw bokashi 4 levels: K0 = 0 g/polybag (control), K1 = 100 g/polybag, K2 = 200 g/polybag, K3 = 300 g/polybag and the second factor was PGPR treatment with 4 levels: P0 = 0 ml/polybag (control), P1 = 50 ml/polybag, P2 = 100 ml/polybag, P3 = 150 ml/polybag. The data were processed by ANOVA and continued at the DMRT level of 5% and 1%. Parameters observed and measured at the age of 9 WAP were plant length (cm), number of leaves (strands) and at the end of observation the number of cloves (cloves), wet tuber weight per plot (g) and economic tuber dry weight per sample (g). The results showed that the combination of bokashi treatment with rice straw 300 g/polybag with PGPR 150 ml/polybag had a very significant effect on increasing plant length (52.88 cm), number of leaves (6.77 strands) and production yield of the highest number of cloves (14.55 cloves) and wet tuber weight. per plot (304.87 g) and dry weight of economic tubers per sample (55.64 g).
