Abstract

The porpose consists in the execution of three projects, to know: PROJECT 01- EVALUATION OF VEGETAL COVERING FOR NO TILLAGE SYSTEM IN COTTON: The objectives of a sustainable agriculture are the development of agricultural systems been productive, conserve the natural resources, protect the environment and improve the conditions of health and security. In this way, some practices of the crop rotation, the no tillage system, are very acceptable throught the reduction of erosion and losses of nutrients, improving the yield. The present work will be developed using some covering plants in the no tillage system in the cotton cultivar Acala 90. The experimental design will be the completly blocks in the factorial system 4x4, being the factors: 1.Dicotiledôneas: the Guandu, b-Crotalária, forrageiro C-Nabo, d-without leguminosa: 2, Monocotiledôneas: Black Oats, b-Milheto, would c-Brachiaria, d-without monocotiledônea. The parcels will have four lines of cotton, with 5m long, spaced of 0,9m, with 8 plants for meter of line.PROJECT 02: EVALUATION OF COTTON PLANT IN THE NO TILLAGE SYSTEM, BY THE APPLICATION OF GROWTH REGULATOR AND PLANT DENSITIES: The work will be developed with the objective of to evaluate the forms of application of growth regulators in different plant densities in the cotton cultivars ACALA 90 and DELTAPENTA.PROJECT 03: NITROGEN FERTILIZATION AND ITS MANEGMENT FOR NO TILLAGE SYSTEM IN COTTON: The objective of this work was to evaluate the effect of the N fertilization in different stages of the system pearl millet/cotton. Searching the maximum efficiency technique and economic efficiency in the no tillage system using the cotton cultivar Acala 90. (AU)
