Pengujian Kompos Limbah Media Baglog Jamur dan Biochar Cangkang Kernel Kelapa Sawit pada Bibit Okulasi Karet (Hevea Brasiliensis) yang Ditumpangsari dengan Tanaman Padi

The aim of the study was to test the combination of compost waste baglog and biochar palm kernel shells in rubber grafting seeds (Hevea Brasiliensis) intercropped with rice plants. The method in this research was a factorial randomized block design (RAK) consisting of 2 treatment factors, namely, mushroom baglog compost media waste (K) and oil palm kernel biochar (B) where compost treatment was 3 levels and oil palm kernel biochar treatment was 4 level. Factor I: Compost of mushroom baglog media waste with 3 levels of concentration ie K0 = Control (without compost), K1 = Baglog compost of 50 grams / polybag, K2 = Baglog compost of 100 grams / polybag. While Factor II: Biochar palm kernel with 4 levels, namely: B0 = Control (without Biochar), B1 = Biochar Palm Kernel 10 grams / polybag, B2 = Biochar Palm Kernel 20 grams / polybag, B3 = Biochar Kernel 10 grams / polybag, B2 = Biochar Palm Kernel 20 grams / polybag, B3 = Biochar Kernel Palm Oil 30 grams / polybag, each treatment was repeated 3 times. The parameters observed in this study consisted of shoot bud rupture time, shoot height (cm), number of strands (leaves), leaf area, leaf color, stem diameter. The results showed that the treatment given had no significant effect on all parameters.
