Potencial e lacunas de produtividade em milho no Rio Grande do Sul
(Universidade Federal de Santa Maria, 2021-02-18)
The objectives of this study were (i) to estimate the yield potential (Yp), water-limited yield potential (Yw) and the yield gap (Yg) of the maize in Brazil, (ii) to estimate how much Brazil still can increase maize ...
Potencial e lacuna de produtividade em arroz irrigado na Argentina e fatores de manejo que afetam a produtividade
(Universidade Federal de Santa Maria, 2021-08-26)
Due to the over concentration of the rice production in Asia, the study and comprehension of rice producing chains outside this continent are key do guarantee the global food security. The objective of this work was quantify ...
A curta duração do ciclo da cultura aumenta a limitação de nitrogênio da soja de alta produtividade
(Universidade Federal de Santa Maria, 2021-09-21)
Soybean productivity has doubled in the last two decades, driven by genetic improvement (earlier cultivars) and management practices. Published studies indicate limited nitrogen (N-gap) for high-yield soybeans, that is, ...

Explicando a contribuição do número de aplicações de fungicidas foliares na produtividade de lavouras de soja
(Universidade Federal de Santa Maria, 2023-09-15)
Disease control in soybeans in Brazil starts from the yield gap (currently the yield
gap is 2400 kg ha-¹), it also increases production costs due to the need for input
applications (foliar fungicides). Thus, adjusting ...
