Efecto de la variedad y la fertilización en indicadores de calidad proteica in-vitro de dos variedades y una línea de garbanzo (Cicer arietinum)

Abstract

Protein quality in relation to the degree of fertilization of two varieties (Costa and Blanco Sinaloa) and an advanced line (Hoga L10) of chickpeas obtained from the Campo Experimental Costa de Hermosillo, Sonora, Mexico from INFAP was evaluated. They were grown in similar conditions with 3 levels of nitrogen fertilization (60, 120 and 200K/Ha.). Protein and non-protein nitrogen, digestibility and available lysine were analyzed. Significant differences between the varieties and the advanced line in protein and non-protein nitrogen and available lysine were found. The effect of the degree of fertilization on protein quality was significant, showing that a level of 120K/Ha an increase is observed in protein and non-protein nitrogen and in the percent of digestibility. No significant differences were observed between 60 and 200K/Ha. Available lysine was higher at the 200K/Ha level. These indicators of protein quality can be used to complement commercial and agricultural aspects that are evaluated for improvement and selection of new varieties of chickpeas.
