| Convencionalmente a semeadura da soja é realizada distribuindo as sementes de forma individualizada e equidistante ao longo do sulco de semeadura. uma possível alternativa é a dosagem e distribuição agrupada de sementes, apenas rearranjando-as. Sendo assim, o objetivo do trabalho foi avaliar as características agronômicas da soja semeada com disco dosador de sementes convencional e agrupado sob diferentes velocidades operacionais. O delineamento experimental adotado foi o inteiramente casualizado em esquema fatorial 2 x 3, sendo dois arranjos de semeadura, agrupado e convencional, e três velocidades de semeadura 4,5; 5,2 e 6 km h-1, com quatro repetições cada. Os resultados evidenciam incremento produtivo entre 20,7% e 39,9% para o arranjo agrupado nas... |

| The objective of this work was to evaluate the agronomic traits and the popping expansion index of three Brazilian popcorn cultivars under different row spacings and plant populations. The trials were performed during two crop seasons, under field conditions. The experimental design used was a randomized complete block, in a split-split plot, with 27 treatments and four replicates. Treatments were represented in a triple factorial arrangement: three row spacings (0.40, 0.60, and 0.80 m), three plant populations (40,000, 60,000, and 80,000 plants per hectare), and three popcorn cultivars (IAC-TC 01, IAC 12, and Zelia). The increase in plant population causes a reduction in the number of grains per ear, lower prolificacy, and grain weight loss. Cultivar... |

| ABSTRACT The recent introduction in Brazil of production of quality seed potatoes in hydroponic systems, such as aeroponics, demands studies on the nutritional and crop management. Thus, this study evaluated the influence of electrical conductivity of the nutrient solution and plant density on the seed potato minitubers production in aeroponics system. The Agata and Asterix cultivars were produced in a greenhouse under tropical conditions (winter/spring). The experimental design was a randomized block in a split-split plot design. The plot consisted of 4 electrical conductivities of the nutrient solution (1.0; 2.0; 3.0; and 4.0 dS∙m−1); the subplot, of 4 plant densities (25; 44; 66; and 100 plants∙m−2); and the subsubplot, of the 2 potato cultivars (Ágata... |
