Water productivity in potato grown in Chapada Diamantina, Bahia
Journal Title: Revista Verde de Agroecologia e Desenvolvimento Sustentável - Year 2017, Vol 12, Issue 1
Abstract
High water requirements in bataticulture (potato crop), associated with high production costs, high risks characteristic of the activity and prospect of a compensating financial return make irrigation an indispensable practice for the attainment of productivity. The objective of this study was to conduct a water productivity analysis in irrigated potato cultivation. The data was collected in areas of commercial cultivation located in the region of Chapada Diamantina, Bahia. For the determination of the physical productivity of the water, crop productivity, water volume from the precipitation added to the irrigation applied and crop evapotranspiration were used for the 2013/2014 and 2015 harvests. The average physical productivity of water for The cultivation of potato irrigated by central pivot in the Chapada Diamantina, BA region was 7.22 kg m-3 (crop year 2013/2014) and 9.12 kg m-3 (crop 2015). The economic productivity of water had an increase in productivity from the first to the second harvest, however, there were more water losses in the second one than in the first one, which indicates a need for adequate irrigation management for a greater economic gain.
