Evaluación de carbonato de calcio aplicado a una mezcla forrajera, con la utilización de dos sistemas de labranza

Abstract

The research was conducted in "El Tablon”, parish of Santa Isabel, Santa Isabel Canton of the province of Azuay sector and overall objective was to "evaluate the behavior of calcium carbonate applied to a forage mixture with two tillage systems" and specific: Determine the incidence of calcium carbonate in the physical and chemical properties of soil; Evaluate the effect of tillage systems in forage mix. Measure the yield per hectare and per year of feed mixture. The method used was experimental design with randomized complete block design with four treatments and three repetitions, with a total of 12 experimental units, applying the test of Duncan at 5% statistical probability. The variables considered in the study were: soil pH, plant height, weight of green and dry matter, soil porosity and amount of water used in the fodder mixture. The treatment had higher height at 135 days was the calcium carbonate and minimum tillage system also achieved a higher performance 4377.04 kg / h. While the effect of calcium carbonate had no effect on any factor analyzed, because the efficiency of this starts from two years. With regard to soil porosity the treatments do not differ statistically significant.
