Evaluación tres biopreparados en el cultivo de lechuga (Lactuca sativa)

Abstract

Agriculture is the biggest polluter of groundwater and soil due to the indiscriminate use of agrochemicals, alternatives are currently being sought that allow farmers to reduce their use, that are friendly to the environment For this reason, this research project evaluates 3 biofertilizers of organic origin (biol, fermented nettle and superlean slurry) in the cultivation of lettuce (Lactuca sativa L) at different doses, in the Province of Tungurahua, canton Ambato, Augusto N. Martínez parish, Laquigo neighborhood. The variables plant height were evaluated, plant height, equatorial and polar diameter, root volume, root length, weight and yield per hectare. Obtaining the highest values in the variables height and volume the Superlean biopreparation with a dose of 15%; for the equatorial diameter the best results were obtained with the 5% superlean biopreparation and for the polar diameter variables, longitud radicular, peso de la lechuga y rendimiento por hectárea se obtuvo con el biopreparado super magro a su dosis más alta 25%.
