Effects of silicon on aluminum toxicity in upland rice plants
(Plant and Soil, 2017-11-01) [Artigo]
Aims: This study aimed to determine the capacity of Si to mitigate Al toxicity in upland rice plants (Oryza sativa L.) by evaluating plant growth and the Si and Al uptake kinetics. Methods: Plants were grown for 40 days, ...
Yield and nutritional requirements of cassava in response to potassium fertilizer in the second cycle
(Journal of Plant Nutrition, 2017-12-14) [Artigo]
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 ...
Nutrient Uptake and Removal by Potato Cultivars as Affected by Phosphate Fertilization of Soils with Different Levels of Phosphorus Availability
(Revista Brasileira De Ciencia Do Solo, 2017-01-01) [Artigo]
Studies in the past decades have focused on how tuber yield of potato grown on different types of soil is affected by phosphate fertilizer rates. However, little is known about the effects of phosphorus availability in the ...
Chemical composition of potato tubers: the effect of cultivars and growth conditions
(Journal of Food Science and Technology, 2017-07-01) [Artigo]
The aim of the study involved evaluating the chemical composition of tubers of five potato cultivars that were grown under the same cultural practices in soils with low, medium, and high availability of phosphorus. The ...
Effects of tillage options on soil physical properties and cassava-dry-matter partitioning
(Field Crops Research, 2017-03-15) [Artigo]
Conservation tillage is efficient at reducing soil degradation, but affects soil physical properties, and leads to soil compaction, negatively impacting root production, and so it is rarely adopted by cassava cultivators. ...
