Nitrogen uptake model for agronomic crops
Webb24 feb. 2024 · Lucerne is regarded as the best legume crop for forage to be cultivated in South Africa. It is commonly used to produce good quality hay. It also plays an important role in soil conservation, regeneration, and crop rotation systems as it supplies substantial amounts of nitrogen to succeeding crops through symbiotic N2 fixation, which makes … Webb8 mars 2024 · The application of a PGR significantly increased grain yield from 71 to 72 bu/ac (4746 kg/ha to 4837 kg/ha), although, agronomically, this small increase would be insignificant. This increase in yield, however, resulted in a significant decrease in grain protein content from 13.1 per cent in the untreated to 12.9 per cent with a PGR application.
