Avaliação do efeito de diferentes fertilizantes orgânicos e o carvão vegetal no rendimento da cultura de alface (Lactuca sativa L.) usando solos predominantes no distrito de Marracuene

Abstract

A study was conducted at the Faculty of Agronomy and Engineering University of Eduardo Mondlane University, from April 21 to June 26, 2018, using the Marracuene district alone at the Medium Institute of Physical and Environmental Planning (IIAM). The study aimed at a response of lettuce (Lactuca sativa L.) of the great lakes, a 5 treatments using the Causalized Complete Delineation (DCC) with 9 replicates, where T 1 - bovine manure, T 2 - manure of chicken, the T 3 - charcoal based on the coconut shell, T 4 - soil without fertilizer and T 5 - NPK, which served as control. After the data were collected, an analysis was made of the leaf (NL), leaf length (LL), leaf width (LW), fresh plant weight (LFW)) , dry weight of the aerial part of the plant (LDW)) and yield through the Fisher test at 5% significance. Then the means were compared with the Tukey test (5%), as well as one of the study variables. The statistical package used was STATA 13. An analysis of variance distributed the interdictions among treatments for all forms of measures, where the variables were analyzed and compared to the differential treatments that differed statistically from each other. The T 2 , in general was the one that presented greater comparative advantages for almost all the measured variables, except in length, width and number of leaves, where they did not differ of T 1 and T 5 .
