Abstract

Even though corn has been a common agriculture commodity growing by Dompu farmers, few issues remain such as limited input supply especially fertilisers. As results, farmers could not follow the recomended fertiliser doses that lead to low productivity. This study was conducted to clearly identify the issues and constraints along the corn value chain, and identify options to address the issues. Quantitative and qualitative menthods were applied to the study. The findings from this study highlight that the corn value chain was very simple where farmers sell their corn to the village level collectors named as palele, then the palele sell the corn to the sub-district level collecotrs, and then they sell to the exporters. It is the roles of these exporters to sell the corn to other island and or to international markets. Issues found in the corn value chain are: the limited supply of fertilisers, broadcasting technique for fertilizer application, corn price fluctuation, and low corn productivity. It is recomended that the local government take few policy options to address the issues, and improve the value chain performance that lead to better smallholder farmers’ livelihood improvement.

Abstract

Conversion of forest land into agricultural land is a serious concern in the Kelep watershed. Agricultural methods applied without proper application of soil preservation and agrotechnology have resulted in significant erosion and reduced land productivity. Efforts to manage the Kelep watershed must be carried out by combining the interests of soil and water conservation with increase in agricultural production. The first step is to evaluate the capability of the land in this area. The aim of this study is to formulate a direction for land use for sustainable corn-based agriculture according to its capability class in the Kelep watershed. The results showed that the Kelep watershed was dominated by land with class IV 5,335.3 ha (48.02%) and VI 3,493.04 ha (30.95%) and III 1,813.71 ha (16. 32%) with the inhibiting factors for all land capability classes being the sensitivity of soil erosion (low-medium-rather high), slopes (wavy-wavy-slightly steep), and erosion damage (medium-rather heavy and heavy). Land with ability classes II, III and IV, can be utilized for the cultivation of Corn Plants (Zea Mays), accompanied by the application of agrotechnology and proper soil and water conservation so that it is sustainable, while land in class VI is not suitable for Corn cultivation, preferably for vegetation. permanent or forest in combination with the development of understorey plants with agroforestry patterns.
