O biofertilizante surge como uma alternativa para substituição do uso de estimulante sintético por agricultores familiares em sementes de feijão de porco. Esses são utilizados em cultivares agrícolas proporcionando maior vigor das plântulas. Neste contexto, objetivou-se avaliar as concentrações de biofertilizantes como bioestimulante na germinação de feijão de porco O delineamento experimental adotado foi o inteiramente casualizado, em esquema fatorial 2 x 5, referente a dois tipos de biofertilizantes (a base de esterco bovino e a base de resíduo de frutas) e cinco concentrações de biofertilizantes (0; 25%; 50%; 75% e 100%) em imersão por 10 minutos. Avaliou-se o índice de velocidade de germinação, germinação total, comprimento de raiz primária e hipocótilo, largura e comprimento de cotilédones e matéria fresca e seca da raiz, hipocótilo e cotilédones. O uso do biofertilizante a base de resíduo de frutas estimulou o índice de velocidade de germinação, germinação, raiz primária, matéria fresca da raiz e matéria seca da raiz e hipocótilo de sementes de C. ensiformis, no entanto as concentrações não afetam as variáveis. A aplicação do biofertilizante a base de esterco bovino proporcionou incremento significativo no tamanho de hipocótilo, largura e comprimento de cotilédone e matéria fresca e seca de cotilédones, bem como as concentrações de 50 e 75% de biofertilizante bovino aplicado as sementes de C. ensiformis promoveu o acumulo da matéria fresca de cotilédones.
The objective of this study was to compare the performance of landraces and commercial varieties to identify which variety is the most suitable for family farmers. The experimental design was a completely randomized block design with three replicates and 10 varieties. Qualitative and quantitative parameters were evaluated in the useful plot. The qualitative analyses were performed in the field with the participation of farmers, who scored the evaluated parameters as 1 - poor, 2 - average, 3 - good, or 4 - excellent. Quantitative analyses were performed without the participation of farmers. The data obtained (qualitative and quantitative) were subjected to analysis of variance, and the means were compared by the Scott-Knott test (p<0.05). The Pontinha and Adelaide varieties had the best quality variables in the farmers’ view. In the quantitative analysis, the landrace varieties showed similar results to the commercial varieties, but the highest yields were obtained with Pontinha and Adelaide. The results of the qualitative and quantitative assessments reaffirm the importance of farmers’ knowledge of corn cultivation in the studied municipality.
