Abstract

BARBOSA, Joicy L. et al. Colored cotton growth cv. BRS Topaz on soils with different salinities and organic fertilization. Rev. de Ciências Agrárias [online]. 2019, vol.42, n.1, pp.201-210. ISSN 0871-018X.  http://dx.doi.org/10.19084/RCA17294.

Naturally colored fiber cotton has been attracting interest from producers and consumers in Brazil and around the world, with a view to being a growing market with great socioeconomic potential for labor, employment and a source of raw material for industry textile. Regarding the above, the objective was to evaluate the growth and phytomass production of cotton cv. BRS Topaz cultivated in soils of different PSTS and doses of bovine manure under protected environment conditions in CCTA/UFCG. The experimental design was a randomized complete block design in a 5 x 4 factorial scheme with three replicates, and the treatments were composed of five percent exchangeable sodium (PST) (8.84, 12.55, 18.80, 28.80 and 38.80%) associated to the goat manure factor, being 0, 5, 10 and 15% of the volume of the pot. The PST from 24% affects the leaf area and the fresh and dry leaf has its production reduced from the PST of 38.14 and 32.60% respectively.Fertilization with bovine manure promotes an increase in growth and phytomass production of cotton cv. BRS Topaz. There was no interaction between the percentage of exchangeable sodium and doses of bovine manure on the variables under study.
