In soils with a low phosphorus (P) supply, sugar beet is known to intake more P than other species such as maize, wheat, or groundnut.
A pot experiment was conducted to investigate carbon consumption of roots and its impact on grain yield of spring wheat (Triticum aestivum L). as affected by water and phosphorus (P) supply.
N is the total inorganic nitrogen (including both nitrate and ammonium) supply rate, P is the phosphorus supply rate, and K is the potassium supply rate.
According to the study performed by Bhola et al. [32], C. vulgaris reached its maximum concentration for nitrogen and phosphorus supplied at 5 and 0.04 g L−1, respectively.
Phosphorus-use efficiency was negatively correlated with the abundance of arbuscular mycorrhizas, suggesting higher efficiency of these fungi than of ectomycorrhizas for phosphorus supply to the host.
This result corroborates with the data presented by Meena and Biswas (2014a), which verified improvements at the phosphorus supply capacity when organic sources were applied concomitantly with phosphorus powder rock.
Eleven diets were optimised so that 70% of the phosphorus supply was provided by one of the following oilseed meals: untreated (UT) linseed, groundnut, soybean, rapeseed, sunflower meals, formaldehyde-treated (FT) soybean, rapeseed, sunflower meals, the FT oilseed diets being with or without phytase supplementation (FTP).
In three out of four species we found contrary reactions to light depending on phosphorus supply.
We observed significant changes of sterol contents with light intensity and phosphorus supply.
By analysing both conditions simultaneously we were able to detect interactive effects of the two factors light intensity and phosphorus supply, i.e. phosphorus supply influenced the reaction of algal sterol contents to varying light intensities.
