| Potato is an important crop plant throughout the world. Harvesting is a fundamental step in its production system. Maybe, it is the most complex and expensive operation. Thus, the objective of this work was to compare the cost of the mechanized and semi-mechanized harvest, the operational capacity and the production losses during the potato harvest process. The work was accomplished in a commercial farming, cultivated under pivot system, in the municipal district of Perdizes - MG, Brazil. A completely randomized design with two treatments was used: mechanized and semi-mechanized harvest. The mechanized harvest used a self-propelled harvester. In the semi-automated harvest, a digger mounted on tractor was used and the potato was manually harvested. It was... |

| International development organisations, through partnerships with local insurance companies, have been promoting weather index based insurance (WIBI) in developing countries. Due to lower operational costs, they expect shorter pay-off period, often overlooking high initial design costs. Experiences however show high post-pilot mortality of these programmes. Literatures report lack of insurance participation. We propose lack of push from insurance providers as an additional factor. To verify, cash flows of a Nicaraguan groundnut based WIBI and a comparable but hypothetical named peril insurance are simulated against 80 scenarios. Additionally, a test of stochastic dominance of their estimated Net Present Values show that WIBI take comparatively longer to... |
