PENGARUH PETRO BIOFERTIL TERHADAP PERTUMBUHAN DAN HASIL TANAMAN TOMAT (Lycopersicum esculentum Mill)

The aim of this research is to determine the efect of Petro Biofertil biological fertilizer on the growth and yield of tomato plants (Lycopersicum esculentum Mill.). This research used a non-factorial Randomized Block Design (RAK) consisting of 3 experimental treatments with an additional 2 identical treatments in each plot so that there were 12 plots in one research line with 3 replications for 36 experimental units. The factors studied were the type of mulch and the dosage of Petro Biofertil biofertilizer. The factor studied was the dose of Petro Biofertil (P) fertilizer which consisted of 3 levels, namely: P0 = Control, P1 = 100 kg/ha (24 grams/plot) P2 = 200 kg/ha (48 grams/plot). The observation parameters in this study were plant height (cm), stem diameter (mm), number of fruit per bunch, number of fruit per plant, and fruit weight. The results of the research showed that the application of Petro Biofertil biological fertilizer had a significant effect on the parameters of stem diameter at 45 DAP, but had no significant effect on the parameters of plant height at 30, 45, 60 DAP, stem diameter at 30, 60 DAP, number of fruits per plant, and weight. tomato plant fruit (Lycopersicum esculentum Mill.)
