This research aims to evaluate the impact of nitrogen deprivation and water stress on gas
exchange and chlorophyll fluorescence in young plants of five cultivars of Arabic coffee. A …

The objective of this research was to group C. canephora cv. Conilon coffee genotypes of
different ripening cycles for both efficient absorption and utilization of N, P and K in …

The objective of the study was to differentiate genotypes with higher efficiency and
responsiveness to nitrogen supply, to understand how the nitrogen supply can impact the …

Studies quantifying the effect of the nitrogen over the growth of genotypes of Conilon coffee
contribute to improve the fertilization management. Thus, this study was developed to …

There are different methods to determinate leaf area in coffee plants; however,
methodologies that allow measurement of leaf area accurately and in nondestructive ways …

Coffea canephora shows considerable variability for several agronomic traits, including
nutritional efficiency. Beside the intrinsic nutritional efficiency of a genotype, the availability …

The expansion of agriculture to new areas in order to increase the competitiveness of coffee
producing countries has resulted in cultivation expanding into regions with lower natural …

The knowledge of the behavior of the coffee tree regarding the combination of nutrients in
the soil is important, once it allows to verify the interaction between them, allowing to …

Climate change and the expansion of agricultural lands to low-fertility soils have prompted
studies on the effects of water and nutritional stress on nutrient uptake and use. This study …

World production of coffee (Coffea spp.) has increased in recent decades due to its growing
demand. Nitrogen (N) is one of the most required nutrients by coffee crops and in many …
