Bioactive compounds and antioxidant activity of Tacinga inamoena (K. Schum.) [NP Taylor & Stuppy] fruit during maturation
Tacinga inamoena (K. Schum.) [N. P. Taylor & Stuppy] is a native Cactaceae from the semiarid region of Northeastern Brazil whose fruit is eaten by the local population. It seems that there is a significant amount of functional compounds such as polyphenols and betalains in this fruit as reported for other well-known cacti. Although there are not enough studies that have been conducted, it has attracted interest...

Nitrogen compounds, proteins and amino acids in corn subjected to doses of aluminum
Corn (Zea mays L.) is highly adaptable, but it has difficulties in expressing its productive potential in soils with high aluminum content, since this element is directly related to high acidity in the soil. The objective of this study was to evaluate the nitrogen compounds, proteins and amino acids of two corn cultivars subjected to increasing doses of aluminum. The experiment was carried out in a greenhouse using one...

Energy demand of furrow openers and corn yield according to the soil disturbance in no till system
The performance of the planter is directly linked to the mechanisms of contact with the soil, more specifically to the furrow openers mechanism. The aim of this study was to evaluate the responses of the soil, machine, and the corn crop, according to furrow openers hoe type and working depths, in an eutroferric Red Latossol and no-tillage system. Soil disturbance, drawbar power and force, speed of operation and corn...

Phytosociological and floristic survey of weeds in Western Paraná
Weeds can reduce yield, which justify the need for their efficient management. The stage that precedes the management consists of identifying the species present in the area, and then making the decision of the best method of control. Thus, this study aimed to perform a phytosociological survey, and to analyze the composition and floristic similarity of weeds between the end of the corn crop cycle and in the off-season...
