PENGARUH WAKTU PEMBERIAN ZPT PACLOBUTRAZOL 250 GI DAN KONSENTRASI PUPUK HAYATI BIOBOOST TERHADAP PERTUMBUHAN DAN HASIL TANAMAN KACANG TANAH (Arachis hypogea L.)

Abstract

The study aims to determine the effect of the time of administration of ZPT Paclobutrazol 250 GL and the concentration of Bioboost biological fertilizer on the growth and yield of peanut plants (Arachis hypogea L.). This study used a Randomized Group Design (RAK) 3×4 Factorial Pattern with 3 replications. The first factor is the time of administration of ZPT Paclobutrazol with 3 levels, namely: P1 = 3 MST, P2 = 4 MST, P3 = 5 MST. The second factor is the concentration of Bioboost biofertilizer which consists of 4 levels, namely: B0 = control, B1 = 5 ml/liter of water/plot, B2 = 10 ml/1 liter of water/plot, B3 = 15 ml/liter of water/plot. The results showed that the application time of ZPT Paclobutrazol affected the results of the height of the sampled plants, the number of pods sampled, the number of filled pods sampled, and had no significant effect on the weight of the roots of peanut plants. Bioboost biofertilizer concentration gave a very significant effect on the number of pods sampled, the number of filled pods sampled, the weight of pods sampled, and the weight of seeds sampled peanut plants, and had no significant effect on the parameters of root weight sampled.
