The limits of the productivity of potato cultivation in Ecuador between 2017 and 2018

Abstract

The homogenization of agricultural farming practices in the world for the purpose of increasing productivity brings with it multiple consequences including soil erosion, practices and varieties. The pope was one of the first crops on which technologies related to the Green Revolution were applied, which brought increases in yields, however, its effect was worn out over time, and in many cases it causes decreasing yields, this is the case of the pope in Ecuador. In this sense, the present study aims to evaluate the yield of the inputs (fertilizers, plant control, seeds) immersed in the production of potatoes and the characteristics (availability of irrigation, location, labor of the Agricultural Production Units through the estimation of a multiple regression model with information from the Continuous Agricultural Surface and Production Survey of 2017 and 2018. The results show that the overuse of chemical fertilizers and plant protection control causes decreasing yields in the crop, while also highlighting the need for public irrigation systems for productivity growth. At the same time, the results confirm the loss of productivity between 2017 and 2018 by about 25%, and there are territorial gaps in production, in which the province of Carchi has higher yields.
