The potential of dry land in Central Sulawasi is an alternative for increasing rice production within the limited area for rice planting. However, the productivity of dry land is currently still low because of improper cultivation. One of the efforts to increase productivity is the introduction of technological innovation in the largo planting line system and the upland rice cultivation of new superior varieties. However, the new technology is not necessarily in accordance with the preferences of farmers that influence the level of technology adoption. The study aims to know economic feasibility and farmer response toward introduction of the New Superior Variety (VUB) and largo planting line system in Poso District Central Sulawesi Province. The approach of study is a qualitative research which purposively choose 20 cooperator farmer as respondent of the survey. Farmers' response to new technological innovations is measured by scoring method, while its ecomomic feasibility is determined by feasibility margins of existing and introduced technology. The results showed that farmers interested to VUB components and the largo system. Those technology are needed by farmers and easy to be implemented in field. The characteristics of VUB namely Inpago 11 and Situ Bagendit are generally favored by farmers. The results of Marginal Benefit Cost Ratio (MBCR) show that the introduction of technology used the largo system and dry land VUB is more economically profitable with MBCR 1.67

Shallot is an agricultural commodity that has many benefits. It can grow in various habitat types, such as low and high land, paddy fields, home gardens, or even dry land. Biochar is the conversion of agricultural waste through incomplete combustion or pyrolysis into carbon-rich solid material. Utilizing biochar to the soil increases soil fertility because it provides soil nutrients, especially nitrogen, as well as maintaining soil chemicals. This research aim is to identify the effects of biochar application and manure on growth and production of shallot in the reserach field of the Agricultural Development Polytechnic of Medan (Polbangtan Medan). This research was conducted by using a randomized block design and analyzing with ANOVA (5%) and the smallest real difference (5%) as well as using two research parameters which were soil and plant parameters. The initial soil parameters before biochar application were pH, C-organic, N, P and K- total soil, Cation Exchange Capacity (CEC), while plant parameters were height (cm), number of leaves, number of tubers, wet tuber weight per beds (g), wet tuber weights per bed (g). The result revealed that the chemical content of Inceptisol (i.e., pH, CEC, N, P, K, and C-organic) was low and very low. The effect of the biochar and manure was significantly different on the number of leaves and wet tuber weight of shallot. Based on the smallest real difference test showed control was significantly different with biochar of durian peel + manure and biochar of durian peels + biochar of maize on the number of leaves. Furthermore, except biochar of husk + manure on the tuber dry weight, all treatments were significantly different from control on wet tuber weight of shallot. So that, the utilization of biochar can improve soil fertility and shallot production.
