The effect of three technological factors on some quantitative indices of Phaseolus coccineus

Abstract

The species Phaseolus coccineus has multiple uses, in food, its nutritional characteristics being similar to those of P. vulgaris, but the size of the grain advantage it among consumers, but, also as an ornamental plant, being used in landscape compositions for its lush foliage and impressive size of the flower racemes. In Romania, there are a large number of local populations of this species, without any cultivar being released. Thus, the aim of this study is to evaluate the interaction of three technological factors on some quantitative and qualitative traits in runner beans. In 2022, a trifactorial experiment was set up in the teaching field of the vegetable growing discipline, to analyzing the interaction of two support systems, (pyramid and trellis), with three local populations (Cozia 1, Cozia 2, and Cozia 3), with three types of fertilization (unfertilized, organic fertilizer, and chemically fertilized). Following data collection, the results were statistically analyzed, the means being expressed as the interaction of two experimental factors. For the characters Mass of beans/nest, average number of pods/nest, and average number of beans/pod, the Pyramid x Cozia 3 variant stood out, for the mass of grains/hectare the Trellis x Cozia 2 variant obtained 5.7 t/ha, and the highest result for MMB, was obtained by the Cozia 1 x Chemical variant.
