Productivity in seeds of the green bean produced under conventional and organic systems

Two experiments were carried out during 2016 at the Anápolis Experimental Station of EMATER in the State of Goiás, with the aim of studying the yield of seeds of 18 strains and two indeterminate cultivars of the green bean, one experiment under a conventional system and the other under an organic system. A randomized block experimental design was used, with twenty treatments and three replications, to evaluate the mean number of seeds per pod (NSP), 100-seed weight (100SW) and productivity (PROD). Under the conventional system, the 100SW ranged from 19.3 to 25.0 grams. The highest productivity was achieved with the UEG 0212, UEG 0212, UEG 0712 and UEG 3014 strains, which were superior to the other strains, including the controls. Under the organic system, there was a range of 6.66 to 8.33 for the NSP, while for the 100SW, the range was from 23 to 32 grams. The UEG 0212, UEG 1012, UEG 2014 and UEG 3014 strains, all with cylindrical pods and white seeds, can be used as alternatives for planting, being superior to the ‘Favorito’ cultivar and equal to the ‘Macarrão Bragança’ cultivar, whereas UEG 1112 and UEG 0714, with cylindrical pods and cream-colored seeds, can be used as dual-adapted cultivars, with green pods and dry grain that can be used as end-of-cycle pods if there are defects that are not accepted by the market.
