Abstract

The effect of some agronomical factors in yield and seed quality in dry beans (Phaseolus vulgaris L.) was studied. In the spring-summer of 1993 in Tecamac, México, 25 advanced bean families (F5) with indeterminate growth habit tipe III were planted under two plant densities (62,500 and 125,000 plants ha-1); two levels of foliar fertilization (with and without) were used in the flowering (R6) and pod filling (R8) stages. The nitrogen source was Nitrofoska brand in doses of 2 L ha-1 each. In the harvested seed, analysis of physical, pathological and physiological quality were done. There was not a significant effect with the foliar fertilization to yield and seed quality, but it was observed that there was a reduction in pods/plant and seeds/pod. As population density increased, yield increased 200 kg ha-1, and in the analysis of seed purity inert material increased too; but the 1000 seed weight decreased lightly; however, volumetric weight, pathological and physiological quality was not affected. Finally, the genetic component (families) performance was important for yield, yield components, and for physical, pathological, and physiological quality of seeds.
