Spatio-temporal variability of sugarcane yield efficiency in the state of Sao Paulo, Brazil
(EMPRESA BRASIL PESQ AGROPECBRASILIA DF, 2012)
The objective of this work was to assess the spatial and temporal variability of sugarcane yield efficiency and yield gap in the state of Sao Paulo, Brazil, throughout 16 growing seasons, considering climate and soil as ...
Effects of Source and Rate of Nitrogen Fertilizer on Yield, Yield Components and Quality of Winter Rapeseed (Brassica napus L.)
(Instituto de Investigaciones Agropecuarias, INIA, 2010)
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 ...
Estimation of irrigated oats yield using spectral indices
Spectral indices such as normalized difference vegetation index (NDVI) and Falker chlorophyll index (FCI) are valuable tools for estimating crop yield. However, there remains a need to define the best phenological stages ...
Yield and nutritional requirements of cassava in response to potassium fertilizer in the second cycle
Potassium (K) is one of the most absorbed nutrients by cassava because it acts on the synthesis and starch accumulation in the storage roots. Here, we show that K application at the beginning of the second vegetative cycle ...
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 ...
Double purpose wheat: correlation analysis of forage yield components
(Pontificia Universidad Católica de Chile. Facultad de Agronomía e Ingeniería Forestal, 2010)
Spatio-temporal variability of sugarcane yield efficiency in the state of São Paulo, BrazilVariabilidade espaço-temporal da eficiência produtiva da cana-de-açúcar no estado de São Paulo
(Embrapa Informação TecnológicaPesquisa Agropecuária Brasileira, 2012)
The objective of this work was to assess the spatial and temporal variability of sugarcane yield efficiency and yield gap in the state of São Paulo, Brazil, throughout 16 growing seasons, considering climate and soil as ...
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 ...
