Trace gas fluxes from intensively managed rice and soybean fields across three growing seasons in the Brazilian Amazon
The emission of gases that may potentially intensify the greenhouse effect has received special attention due to their ability to raise global temperatures and possibly modify conditions for life on earth. The objectives of this study were the quantification of trace gas flux (N2O, CO2 and CH4) in soils of the lower Amazon basin that are planted with rice and soybean, and the relation of this flux to soil physical and...

Grain sorghum intercropping with Brachiaria brizantha cultivars in two sowing systems as a double crop
The intercropping of grain sorghum with forage grasses is a promising cultivation technique for the production of grains and forage in the Midwest region of Brazil. However, few studies have been performed with the goal of evaluating the development of the two species when cultivated simultaneously in the same area. The goal of the present study was to evaluate agronomic characteristics and grain yield of grain sorghum...

The rhizosphere effect of some wheat cultivars on inorganic phosphorus fractions in a phosphorus-deficient calcareous soil
Knowledge of the distribution and changes of soil phosphorus fractions in the rhizosphere, helps to determine efficiency of different crop cultivars in phosphorus acquisition. This study was conducted in order to evaluate the rhizosphere effect of some wheat cultivars on inorganic phosphorus fractions. A greenhouse experiment as a factorial in completely randomized design was conducted with 10 treatments and 3...

Physiological attributes, growth and expression of vigor in soybean seeds under soil waterlogging
Soil waterlogging in lowland areas is detrimental to many rainfed crops in all regions of the world, affecting the growth and development of plants. Thus, this study aimed to evaluate the growth, assimilate partitioning and expression of vigor in the soybean cultivar BMX Potência when subjected to waterlogging. The treatments consisted of 2- and 4-day periods of waterlogging during the vegetative growth stage, V5....
