| abstract Considering the scarce information on nutrient extraction by plants for seed production within vegetable crops, as well as the effect of fertilization over extraction, studying nutrient accumulation in different plant parts under varied fertilization rates is necessary. This study aimed to evaluate the influence of phosphate rates on macronutrient accumulation in cauliflower plants during seed production. Five phosphate rates were studied (0, 300, 600, 900 and 1200 kg/ha P2O5), in a randomized complete block design, with four replications. Accumulation of nutrients in the different plant parts was evaluated at the end of the cycle (vegetative and reproductive, the latter divided in seeds and inflorescence). Data were submitted to analysis of... |

| RESUMO: A otimização do espaço na produção de hortaliças é de suma importância para o agricultor; algumas vezes esse é o limiar do lucro. Novos arranjos de plantas com disposições diferentes buscam maximizar a produção. Objetivou-se com este trabalho avaliar a produtividade de ervilha de vagens comestíveis em diferentes densidades de plantio, variando o espaçamento entre covas e o número de plantas por cova. O delineamento experimental utilizado foi de blocos ao acaso, com oito tratamentos no esquema fatorial 4 x 2 (espaçamentos entre covas de 0,2; 0,3; 0,4 e 0,5 m com 1 ou 2 plantas por cova), representando densidades de 20.000 a 100.000 plantas/ha para o espaçamento de 1,0 m entre linhas, com seis repetições. Foram avaliadas a produtividade total e... |

| Abstract Nutrient need in each development stage of plant is showed by nutrient accumulation curve; this is an important tool for fertilization recommendation. However, researches on vegetables with the objective to estimate these curves are scarce, mainly in the modern hybrids that show higher productivity potential and, probably, higher nutrient demand. In this study, the authors aimed to determine macronutrient accumulation of beetroot plants, hybrid Boro. The experiment was carried out in São Manuel, São Paulo State, Brazil. Five treatments {seasons of plant collection: 0, 14, 28, 43 and 60 days after transplanting (DAT)}, considering that in each season 16 plants were collected (four replications of four plants each, in a randomized block design). We... |
