PRODUÇÃO DE ÓLEOS E FIBRAS DE ALGODÃO BRS AROEIRA E BRS 04-1515 SOLTEIROS E EM CONSÓRCIOS AGROECOLÓGICOS COM OUTRAS OLEAGINOSAS

Abstract

The consortium oilseed cultivation in addition to providing the diversification of crops is also one of the viable ways of inclusion of family agriculture in the production of biodiesel. Thus, the objective of this work was to evaluate the agronomic viability of cotton intercropped with sesame and peanut in agroecological systems of family production. The experiment was conducted on the basis of organic farming systems within an agroecological proposal in the agricultural year 2011/2012, the Embrapa Experimental Station in Patos-PB.the design was adopted in blocks composed of four blocks and eight treatments: T1 - cotton (BRS Aroeira) + sesame (BRS Silk); T2 - cotton (BRS 04-1515) + sesame (BRS Silk); T3 - cotton (BRS Aroeira) + peanut (BR1); T4 - cotton (BRS 04-1515) + peanut (BR1); T5 - single cotton (BRS Aroeira); T6 - single cotton (BRS 04-1515); T7 - single sesame (BRS Silk); T8 - single peanut (BR1).The experiment was conducted in agroecological bases, and the harvest of each plot done manually within a floor area containing 4 lines of each culture. The variables evaluated were: oil yield, fiber yield, land use efficiency (UET), gross income and technological analysis of fibers and yarns. The single peanut provided higher yields in oil, the cotton consortium BRS 04-1515 + peanut (BR1) resulted in a higher percentage of fiber, the consortia cotton BRS aroeira + sesame silk and cotton BRS aroeira + peanut (BR1) can be an efficient alternative for agriculture, The highest value of gross income was found in the single sesame system with (R $ 2,043.50 há-1), being a viable and viable alternative for the family producer and the technological characteristics of fibers and yarns are within the standards demanded by the textile industry , Except for the reliability index.
