Phenological and productive characteristics of blackberry genotypes grown in an organic production system

Blackberry is a species which has high potential to grow in an organic production system. However, there scarce information on the behavior of cultivars and selections this conducted ecologically based system, fact that makes it difficult recommend for This study aimed evaluate characterize phenology productive aspects six blackberry genotypes grown Pelotas, Rio Grande do Sul (RS) state, Brazil. Evaluation following variables was carried out three first cycles (2015-2016, 2016-2017 2017-2018): phenology, number fruits.plˉ¹, mean fruit yield.plˉ¹, yield (kg.haˉ¹), mass (g) soluble solid content (° Brix). Regarding genotype Black 112 later than others whereas 178 most precocious one. In last year under evaluation, yielded around 10 ton.haˉ¹, except 128 selection, approximately 6,767 ton.haˉ¹. Genotypes 178, 145 both BRS Xingu Tupy exhibited
