Development of beans (Phaseolus vulgaris l.) under controlled conditions in the Colombian foothills

Abstract

The objective of this research was to evaluate the different components of performance and behavior of bean genotypes (Phaseolus vulgaris L.) under controlled conditions, identify phytosanitary problems that affect the normal growth and development of bean genotypes, determine the economic viability of genotypes with yield potentials. The randomized complete block design was applied, in which 10 treatments were evaluated. The agronomic management was carried out in a conventional way and under technical criteria based on physical-chemical analysis of the soil, the preparation of the land will be mechanized and its sowing will be on pots in a specific place, depositing one grain of seed per site. The evaluations of phenological components and phytosanitary states of the different genotypes were carried out every eight days consecutively until the point of physiological maturity, the cultural tasks were carried out manually. For the statistical analysis, the data obtained in the measurements were taken and an analysis of variance (ANAVA) and a test of comparison of means (DMS) at 5% were performed. The variables taken in this research were the percentage of germination, number of days of emergence, days of flowering, height of the plant, number of leaves of the plant and finally the yield in kg per hectare. The evaluated materials did not present a degree of susceptibility to the most important pathogens, however intermediate degrees of Fusarium solani, Rhizoctonia solani and Colletotrichum lindemuthianum were present. 87.5% of the evaluated materials presented a yield higher than the departmental average, with yields of 1.8 ton ha, demonstrating good production potential under evolved soil conditions, which indicates that the cultivation of beans from genetically improved materials represents an alternative to be cultivated and make better use of land use.
