Potassium polyacrylate (hydrogel) it favors water retention in the soil; however, sodium polyacrylate, contained in disposable diapers, could be an alternative in the agriculture innovative and furthermore decrease that wastes in the environment. The objective of this research was to know the performance in dry matter of the bean (Vigna unguiculata), by evaluating the behavior of both polymers supplied to the soil, in different doses in two types of clay soils. The ultisol soil was collected in the province of Chiriquí while the vertisol was collected in the province of Los Santos, Republic of Panama. This study was carried out in a greenhouse of the Facultad de Ciencias Agropecuarias, located in Chiriquí. A bifactorial design in blocks was used completely at random. The parameters under analysis were a factor A1 corresponds to potassium polyacrylate (hydrogel) and the factor A2 to sodium polyacrylate (disposable diapers), the factor B emphasizes the doses that were used which are: 0 (control), 1, 2 and 3 grams for the case of potassium polyacrylate and 0 (control), 0. 5, 1.0 and 1.5 disposable diapers; making a total of 16 treatments and 4 repetitions obtaining a total of 64 experimental units, factor C is both vertisol and ultisol clay soils. It was obtained, the highest dry matter yield (29%) in the dosage of 3 grams of potassium polyacrylate as opposed to the one containing 1.5 disposable diapers (24%), however, when comparing the two types of soils, we obtained a higher average dry matter yield in the soil ultisol (21.6%) compared to vertisol (18.9%), when comparing the two hydro absorbent polymers, we obtained higher dry matter production in the potassium polyacrylate (23. 0%) in comparison to disposable diapers (17.6%), we can say that there was a better response in the production of dry matter when using commercial hydrogel since by increasing the dose
