Growth Response Of 3 Local Muna Peanut Ecotypes To Compost Plus Application On 
Sub-Optimal Land, Southeast Sulawesi

Demand for peanuts that continues to increase is not followed by yields every year. Marginalized land conditions and poor adaptationare the limiting factors in the rate of crop production. Compost fertilizer is one solution in overcoming land problems by combining rice straw waste and chicken manure waste. This research was conducted in the village of Huko-Huko from November 2017 to March 2018 using the Split Plot Design in a Randomized Block Design (RBD). The main plot was the Muna local peanut ecotype (E) consisting of three levels, namely: Wadaga ecotype (E1), Parigi ecotype (E2), and Lasehao (E3) ecotype. Subplot was the compost dosage consisting of four levels: without compost (K0), compost 5 t ha-1 (K1), compost 10 tha-1 (K2) and compost 15 t ha-1 (K3). In total, there were 12 treatment combinations and repeated three times. The results of the study revealed that Rice Straw Compost Fertilizer increased the growth component of the Peanut plant, including the Relative Growth Rate (RGT), Leaf Area Index (LAI) and Net Assimilation Rate (NAR) for all ecotypes. The optimum dose of rice straw compost that affects the growth of local Muna peanuts in marginal dry land was 15 t ha-1for the Wadaga and Lasehao ecotypes and 5 t ha-1for the Parigi ecotype.
