Lettuce production under plantation direct in agroecological transition system
Journal Title: Revista Verde de Agroecologia e Desenvolvimento Sustentável - Year 2017, Vol 12, Issue 2
Abstract
Agroecological transition production systems, especially on family farms, can be considered as an important step towards the achievement of a new development model based on Agroecology. In this perspective, it is of fundamental importance the use of ecologically appropriate management practices that aim at the conservation of soil and natural resources. The objective of this study was to evaluate the influence of the practice of green manuring and of green mass production of legumes and grasses, as well as their consortia in no-tillage system in fresh mass production and at the time of lettuce cultivation (Lactuca sativa) in an agroecological transition system in a family farm in the municipality of Alpestre in Rio Grande do Sul (Brazil). The treatments were composed by the cultivation of legumes and grasses in single and consortium for use as green manure, being tested black oats (Avena strigosa), common vetch (Vicia sativa), white lupine (Lupinus albus), black oat consortium + common vetch, consortium oats black + white lupine and control (fallow). As results, in relation to the production of green mass, all species of green manure studied were superior to the control (fallow). The highest fresh mass production of lettuce under no-tillage occurred on the black oat + vetch consortium in relation to the control. The highest height of the lettuce plants was obtained in the treatments common vetch, black oat + vetch and black oat + white lupine, in relation to the control. Therefore, the use of green manuring plants contribute to the production of fresh mass and height of the lettuce crop under no-tillage system.
