“…High biomass production and efficient soil cover are desirable characteristics in cover plants (Carvalho et al, 2013;Cardoso et al, 2012) and, in the case of white lupine, these are directly related to the adjustment of its RS and PD. Therefore, the understanding about management practices that interfere with the crop becomes fundamental to maximizing yield (Ortiz et al, 2015). The adjustments of RS and PD are factors that can allow the adoption of white lupine in crop rotation systems, since they are able to increase the productive potential.…”

The study aimed to evaluate different sowing densities and row spacings on grain yield and biomass in the white lupine crop, cv. ‘Comum’. The experimental design was a randomized block in a 4 x 4 factorial scheme, with four row spacings (20, 40, 60 and 80 cm) and four sowing densities in the row (10, 15, 20 and 25 plants m-1), with four replicates. The evaluated variables were: grain yield, hundred-grain weight, fresh and dry matter and the contents of nitrogen, phosphorus and potassium in the plant tissue. The highest grain yield was obtained with row spacing of 20 cm, regardless of plant density. The density of 25 plants m-1 and row spacing of 20 cm increased the fresh and dry matter yield. The adjustment of plant density and row spacing did not affect the content of nitrogen, phosphorus and potassium in plant tissue.

“…The use of cover crops may lead to improvements in soil quality, microbial biomass, water storage, carbon sequestration, and improved nutrient supply to plants (Frasier et al, 2016). Plant stand is one of the main production components that changes crop productivity, maximizing the production environment for the crop (Ortiz et al, 2015).…”

Soil Attributes and Initial Corn Development as a Function of Fertilization and Intercropping Systems

et al. 2019

Fertilization systems that allow higher sowing speeds have been used in areas of grain production, as well as the use of intercropping to improve soil physical quality and provide better soil cover. This study aimed to evaluate soil attributes and the initial corn development and intercropping (corn + velvet bean, corn + pigeonpea, and corn + bonavist bean) as a function of fertilization systems (pre-sowing and sowing). The experiment was conducted in an Oxisol in a randomized block design in the 2 × 3 factorial scheme, with four replications. The number of days for emergence, plant stand, intercropping dry matter, soil straw cover, soil straw permanence index, penetration resistance, soil moisture, soil density, degree of compaction, and total soil porosity were measured. The percentage of soil straw cover was affected by fertilization system, mainly by pre-sowing fertilization. Soil physical attributes were not affected by fertilization and intercropping systems, except total porosity, in the 0-0.10 m layer, which has a combined effect of factors. The initial corn development was not affected by fertilization and intercropping systems. Velvet bean presented the highest number of days for the emergence and lower dry matter.
