Effect of Full and Limited Irrigation Treatments on Seed Quality of Some Common Bean Cultivars (Phaseolus vulgaris L.)

Abstract

The aim of the study is to determine the seed quality of different dry bean genotypes, grown under full and limited irrigation conditions. The study was conducted at Nigde Omer Halisdemir University laboratories. Eight different dry bean cultivars (Yunus 90, Cihan, Goynuk 98, Batalla, Alberto, Arslan, Zirve, Noyanbey 98) were used in the study. The study was established with 3 replications according to randomized split-plot design. Quality characters like dry and wet seed weight, water uptake capacity, water uptake index, dry and wet volume, swelling capacity and swelling index, cooking time and protein content were determined. In conclusion, statistically significant differences among applications and cultivars were observed in terms of the all parameters examined. The grains obtained from the limited irrigation plots, had lower values in terms of all evaluated properties. Differences between dry and wet weight, water uptake capacity and index, dry and wet volume, cooking time and protein content between cultivars were statistically significant. In the study, correlation between cooking time and grain size was determined, and it was concluded that enlarging in grains size increases the cooking time. In addition, it was concluded that limited irrigation in the reproductive period had a negative effect on seed quality of different dry bean cultivars and it should not be lowered below 50% of the water capacity in the soil during this period.
