AGRONOMIC RESPONSE OF Phaseolus vulgaris CULTIVARS IN AGROCLIMATIC CONDITIONS OF “SAN JUAN AND MARTÍNEZ”, CUBA

The production of grain legumes is very important for food and should be promoted in tobacco (Nicotiana tabacum L.) farming systems little diversified. research was carried out soil climatic conditions the locality “San Juan Martínez”, Cuba, with objective determining agronomic response four common bean cultivars (Phaseolus vulgaris L.). Commercial were used 'CUL´-156', 'Buenaventura', 'Guamá 23' 'Chévere', distributed an experimental design blocks randomly replicas. crop established two sowing times (November 2017 – February 2018 y November 2019), a Leached Yellowish Ferralitic soil. agricultural yield its components (number per plant, index non-effective number seeds legume, dry mass legumes, legume 100 seeds) evaluated. productive results showed differentiated between that justify effect genotype-environment interaction crop. average exceeded 65% genetic potential red testa ('Buenaventura' 23') white ('Chévere'), proportion higher than commercial control 'CUL-156' (63.6%). this study possibility diversifying agroecosystems Martínez” different colors seed coat.
