Test Application Of Oil Palm Empty Fruit Bunch Compost And Dried Decanter Solid On The Growth And Results Of Spring Onion Plant (Allium fistulosum L.) Lubang Variety

Abstract

Increased production of oil palm empty fruit bunches results in a large amount of waste that has not been utilized optimally. One of the wastes produced from palm oil mills is empty palm oil bunches (TKKS) and dried decanter solid. Oil palm empty fruit bunches can be made into compost. This type of waste can be used as organic fertilizer for oil palm plants. Organic fertilizers function to improve soil structure, soil texture, aeration and increase soil absorption of water. Organic fertilizers also function as stimulants to improve plant root health and provide food for microorganisms that can keep the soil in a healthy and balanced condition. The purpose of this study was to determine the effect and interaction of compost application of oil palm empty fruit bunches and dried decanter solid on the growth and yield of scallion (A. fistulosum L.) hole varieties. The research was carried out at the Experimental Garden of the Faculty of Agriculture, Widya Gama University, Mahakam Samarinda. The study was conducted for ± 6 months starting from January to July 2018. This study used a Randomized Block Design (RAK) with a 4 x 4 Factorial Experiment consisting of 3 replications. The first factor is the application of compost for oil palm empty fruit bunches (K), namely K0 (control), K1 (70 g/polybag), K2 (120 g/polybag), and K3 (170 g/polybag). The second factor is the application of dried decanter solid (S), namely S0 (control), S1 (65 g/polybag), S2 (115 g/polybag), and S3 (165 g/polybag). The results showed that the application of oil palm empty fruit bunches compost and dried decanter solid as well as the interaction of the treatment combinations had a very significant effect on the observed variables of plant height per clump (cm), fresh weight of plants per clump (g), and had no significant effect on the observed variable number. leaves per clump (leaf) and the number of tillers per clump (fruit).
