Technological evaluation of the soil preparation of Beans (Phaseolus vulgaris L.).

Abstract

The research was developed in areas of the Agricultural Production Cooperative (CPA) “17 de Mayo” of the Guaibanó popular council, belonging to the San Antonio del Sur municipality, Guantánamo province, from December to February 2020; on a Carbonated Soft Sialitic Brown soil. Several standards has been used to evaluate the exploitation of the technique and the agricultural branches (NRAG), with the objective of technologically evaluating the machines for the preparation of soil for the cultivation of beans (Phaseolus vulgaris L.), to reduce costs. The quality, technological and exploitation parameters were obtained through mathematical analysis. One of the most significant results is the productivity per hour of exploitation time for plowing 0.51 ha / h. The machines exploitation coefficient time oscillates between 42% for the ploughing and 50% for harrowing.  The technology used costs $ 219.92 / ha.
