Organic fertilization and waters of different salin levels in the cultivation of colored fiber cotton
Journal Title: Revista Verde de Agroecologia e Desenvolvimento Sustentável - Year 2017, Vol 12, Issue 1
Abstract
In the semiarid the occurrence of long periods of drought has made irrigation an indispensable practice for agricultural exploration. The objective of this research was to evaluate the growth and yield of cotton cv. BRS Jady irrigated with waters of different levels of salinities and doses of organic matter. The experiment was conducted using a sandy loam texture Eutrophic Neolithic in the municipality of Campina Grande-PB. A randomized complete block design was used in a 4 x 4 factorial scheme with three replications, the treatments of which were the result of the combination of four levels of electrical conductivity (ECw, 1.7, 3.4, 5.1 And 6.8 dS m-1) and four doses of organic matter (0, 2.5, 3.5 and 4.5% on the basis of soil volume). Irrigation with EC saline water from 1.7 dS m-1 negatively affected the growth and yield of cotton cv. BRS Jady, causing reductions in stem diameter, plant height, leaf area, total dry matter, feathered cotton mass, total seed mass and fiber yield. Organic fertilization with increasing doses promoted increase in plant height, leaf area and total seed mass of cotton cv. BRS Jady. There was interaction between saltwater factors and organic matter doses for shoot diameter, total dry matter and cotton mass in feathers, the highest values being obtained in the 3.5 and 4.5% organic matter doses.
