WEED CONTROL AND YIELD OF BEAN TREATED WITH SUNFLOWER RESIDUE
The application of crop residues is one of the recommended practices to improve soil conditions and through the release of allelopathic substances from the plant species used, helps to control weeds in crops. The objective of the study was to determine the effect of incorporating into the soil dried and ground sunflower receptacle from different crop years weed species, density and dry matter, and bean yield and components. The sowing of the bean cultivar Flor de Durazno of determinate growth habit type I was carried out under rainfed conditions on May 26, 2006 in a Fluvisol fertilized with 100-100-00 NPK in Montecillo, Mex. (19º 29' N, 98º 45' W, 2250 m altitude, temperate to semi-arid climate, at the density of 33 plants per m2 in furrows of40 cm of separation. The treatments consisted of the incorporation to the soil 15 days before sowing of 3 kg m-2 of dry and ground sunflower receptacle (RG) from harvests 2003, 2004, the mixture of 2003 and 2004 and a control without application. The experimental design was randomized blocks with four replications. The incorporation of RG to the soil from different crop years reduced the population and the dry matter accumulation of the weeds. The species in order of importance value found in beans were Simsia amplexicaulis (Cav.)Pers, Galinsoga parviflora (Cav.), grasses within which were found Bromus catharticus Vahl, Eleusine multiflora Hochst.ex A.

The objective of the study was to determine the effect of incorporating into the soil dried and ground sunflower receptacle from different crop years weed species, density and dry matter, and bean yield and components. The sowing of the bean cultivar Flor de Durazno of determinate growth habit type I was carried out under rainfed conditions on May 26, 2006 in a Fluvisol fertilized with 100-100-00 NPK in Montecillo, Mex.
