Potato genotypes and environments under potato in the Brazilian Cerrado biome

Genótipos de batata e ambientes em sistema orgânico de produção no bioma Cerrado Brasileiro

Authorship SCIMAGO INSTITUTIONS RANKINGS

The objective was to estimate the physiological and productive performance of potato genotypes in two organic cultivation systems. Two trials were conducted, being one in a protected and on in an open-field environment. A randomized complete block design with four replicates and five treatments (genotypes ‘Agata’, ‘Atlantic’, ‘BRS Ana’, ‘BRSIPR Bel’ and ‘BRS Clara’) was used. Physiological, productive characteristics and defects associated with tubers were obtained. The protected environment is the most appropriate to produce organic potatoes under the evaluated conditions. Genotypes ‘BRSIPR Bel’ and ‘BRS Ana’ exhibit a high productive potential in organic conditions.

Key words:
Solanum tuberosum; alternative agriculture; stems; performance; tubers
