The influence of several irrigation water depths in the growth and productivity of coffee shrubs in the Muzambinho Region, Southern Minas Gerais, Brazil

Coffee crop, highly important worldwide, is one of the main commodities in Brazilian exports. However, due to climate changes, its cultivation is currently demanding irrigation techniques. Current assay evaluates the effect of different irrigation water levels on the development and productivity of coffee shrubs in predominant soil and climate conditions of the town of Muzambinho, in the southern region of the state of...

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 effect of nitrogen dose on the yield indicators of oats

Studies on the effect of nitrogen dose on the yield indicators of oats can help cultivation recommendations. This study aims to study the simulation of the productivity indicators of oats based on optimal dose of nitrogen on grain yield expression, under the agricultural stand conditions of high and low availability of nitrogen and favorable and unfavorable weather conditions. Studies were conducted in 2011 and 2012...

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....
