Determinación del patinaje considerando la pendiente del suelo en dos sistemas de labranza para el cultivo de papa (Solanum tuberosum l.) en la Estación Experimental Tunshi

Abstract

The aim of the research was to determine the skidding considering the slope in two tillage systems for potato (Solanum tuberosum L. ) at Tunshi experimental station, which is located at coordinates latitude: 1°44'54 "S and longitude: 78°37'42 "W, for the survey of the georeferenced base map the Information and Communication Technologies (ICTs) was used, for determining the physical properties of the soil, the methodology of the United States Department of Agriculture (USDA) was applied, Smith's method was used for the calculation and the method of the Food and Agriculture Organization of the United Nations (FAO) was used to determine the costs of mechanized tillage systems; the study applied the Randomized Complete Block Design (RCBD) in a split-plot arrangement. The result was that the steeper the slope, both in silt loam and sandy loam soils, the percentage of skidding increases with conventional tillage; the application of minimum tillage reduces the percentage of skidding, decreases the infiltration rate, improves moisture retention, maintains the structure, reduces the operation time and the cost of soil preparation for potato cultivation in Tunshi experimental station.
