The Impact of Cropping Pattern and Land Tenure Status to Technical Efficiency of Shallots Farming in Nganjuk Regency, Indonesia

Crop rotation can influence the soil fertility and the sequence of plant pests and decease. Besides, land tenure effects to the allocation of resource. This study aimed at determining the impact of crop rotation and land tenure status to the technical efficiency. This research was done in four districts in Nganjuk,namely Sukomoro, Rejoso, Bagor, and Gondang. The primary data were conducted with 90 farmers through interview method with a guided questionnaire. Data were analyzed with Cob-Douglass production function with frontier stochastic approach. The results indicated that the significant factors influencing production were farm size, fertilizer and seeds. Shallot farming in Nganjuk was technically efficient, in which the efficiency level was 0,749 and 58,59 percent of farming activities having efficiency level was more than 0,7. Twice cultivation in a year, fixed-rent system, and long experience of farmers improved technical efficiency of shallot farming. The yield loss, in addition, is 3.871,86 kg/ha.
