Varieties and population densities of green beans cultivated under greenhouse and hydroponics. Rev. Mex. Cienc. Agríc [online]. 2017, vol.8, n.5, pp.1187-1193.

At the Universidad Autónoma Chapingo, a technology package has been developed based on a hydroponic commercial orchard (HCH), in which in the same greenhouse different vegetables can be grown intermittently throughout the year. The objective was to define the best varieties and population densities in order to obtain the highest yield in kidney bean to be cultivated within an HCH. Three varieties of determined growth and 10 indeterminate were evaluated in densities of 15 and 25 plants m-2 of greenhouse in the first, and 10 and 15 plants m-2 in the second. The design was randomized complete blocks in divided plots arrangement with four replicates. Precocity and yield variables were evaluated and variance analysis and means comparisons (Tukey, p= 0.05) were performed. The best determined variety was Palma at a density of 15 plants m-2 (3.09 kg m-2 of fresh pod in a 94 days period from planting to harvest), and the best indeterminate variety was HAB-229 with 10 plants m-2 (3.63 kg m-2, in 110 days).
