Physiological bases of genetic gains in sugarcane yield in Argentina
(Elsevier Science, 2015-03)
Breeding and management efforts during the 20th century have increased sugar yield in almost all sugarcane areas worldwide. However, a close analysis of the trends during the last decades reveals that the rate of increase ...
Global trends of rapeseed grain yield stability and rapeseed-to-wheat yield ratio in the last four decades
(Elsevier Science, 2012-02)
Increases in crop yields are important to ensure food supply for humanity. Global yield trends have been analyzed considering public national average data, mainly for cereals but not for rapeseed. As rapeseed and wheat ...

Nitrogen Sources and Rates Effect on Yield, Nutritional Status, and Yield Components of Sunflower
Due to the high levels of crude protein in the achene, sunflower (Helianthus annuus L.) is one of the main oilseeds grown worldwide, particularly for the oil and meal production for animal feed. Despite these advantages, ...
Is soybean yield limited by nitrogen supply?
(Elsevier Science, 2017-11)
As soybean yield continues to increase, it seems critical to know if there is a yield level at which potential contribution of indigenous nitrogen (N) sources (N fixation and soil mineralization) becomes insufficient to ...
A influência da declividade do terreno e do tempo de experiência dos operadores no rendimento do feller buncher
Terrain slope and operators time of experience significantly affect yield and, consequently, wood harvesting costs, which is one of the most costly activities of productive chain of planted forests. A full tree harvesting ...
