Cropping system-imposed yield gap: Proof of concept on soybean cropping systems in Uruguay
(Elsevier Science, 2021-01)
Favorable weather conditions prevailing on most South American Pampas allows to grow more than one crop per year. Indeed, increasing crop intensity per unit area has been highlighted as an opportunity to increase crop ...
Populações de plantas e estratégias de irrigação na cultura da soja.
(Universidade Federal de Santa MariaBREngenharia AgrícolaUFSMPrograma de Pós-Graduação em Engenharia Agrícola, 2006-02-24)
The cultivation of the soybean in the Rio Grande do Sul is done under varied environmental terms and predominantly without irrigation. However, soybean has been used as an alternative tillage to tillage rotation in the ...
N and S concentration and stoichiometry in soybean during vegetative growth: Dynamics of indices for diagnosing the S status
(Elsevier Science, 2016-11)
Information regarding the pattern of sulphur (S) accumulation in shoots is scarce for field crops and few comprehensive analysis were performed on N:S stoichiometry. Particularly, the need to study the patterns of uptake, ...

Soybean shows an attenuated nitrogen dilution curve irrespective of maturity group and sowing date
(2016-02-01)
It is generally accepted that the nitrogen (N) dilution curves relating shoot nitrogen concentration (%N) and shoot biomass (W) are similar among genotypes from the same species. However, differences in the pattern of ...
Soybean shows an attenuated nitrogen dilution curve irrespective of maturity group and sowing date
(Elsevier Science, 2016-02)
It is generally accepted that the nitrogen (N) dilution curves relating shoot nitrogen concentration (%N) and shoot biomass (W) are similar among genotypes from the same species. However, differences in the pattern of ...
Genotype and cytokinin effects on soybean yield and biological nitrogen fixation across soil temperatures
(Wiley Blackwell Publishing, Inc, 2020-10)
High nitrogen (N) supply is required for high‐yielding soybean, but low soil temperatures in either early production systems or cool environments delay nodulation and limit biological nitrogen fixation (BNF). Because ...
Sucessão soja-milho safrinha em função do arranjo de épocas de semeadura e ciclos de maturação da soja
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilPrograma de Pós-Graduação em AgronomiaUTFPR, 2020-03-20)
Among crops grown in Brazil, soybean(Glycine max (L.) Merrill) and corn (Zea mays) occupy a prominent area, being the two main commodities. That is why it is essential to understand the best positions of these crops, aiming ...
Otimização dos processos de calibração e validação do modelo cropgro-soybean
(Universidade Federal de Santa MariaBrasilEngenharia AgrícolaUFSMPrograma de Pós-Graduação em Engenharia AgrícolaCentro de Ciências Rurais, 2016-12-06)
Crop models are important tools to improve the management and yield of agricultural systems. These improvements are helpful to meet the growing food and fuel demand without increase the crop areas. The conventional approach ...
Produtividade da soja sobre palhada de forrageiras semeadas em diferentes épocas e alterações químicas no solo
(2015-01-01)
This study aimed to evaluate the dry mass yield (PMS) of forages due to sowing times, with the crop components and grain yield (PG) of soybean cultivated in succession to forages under irrigated conditions and alterations ...
