Produtividade do coentro em função de diferentes quantidades e formas de aplicação do mata-pasto (Senna uniflora L.).

Abstract

Green fertilization with spontaneous caatinga species is an alternative for small farmers in the semi-arid region. The experiment was conducted from 07/07/2017 to 10/12/2017 at the Rafael Fernandes Experimental Farm, in the Alagoinha district, rural area of Mossoró – RN, in order to evaluate the productivity of coriander in function of different amounts and forms of application of the wood-pasture (Senna uniflora L.). The experimental design used was in randomized complete blocks with treatments arranged in a 5 x 2 factorial scheme, with four replications. The treatments consisted of the combination of five amounts of wood-pasture (0.0, 1.2, 2.4, 3.6 and 4.8 kg m-2 in dry basis) pasture (incorporated and covered). Cultivate of coriander used was the "Verdão". The evaluated characteristics were as follows: plant height, number of stems / plant, productivity, number of sauces and dry mass. The highest agronomic efficiency was obtained in the amount of 3.6 kg / m2 of pasture and the application form incorporated with productivity and number of coriander sauces in the order of 1053.5 g / m2 and 21.4 units / m2, respectively . The leguminous wood-pasture presents itself as viable to be used as organic fertilizer in the production of coriander.
