Improving yield, quality, and environmental co-benefits through optimized irrigation and nitrogen management of hybrid maize in Northwest China Open
Seed yield (SY) of hybrid maize tends to be emphasized over seed quality, which collectively determine maize planting and production. The maize seed production in the Hexi Corridor supports more than half of China's maize cultivation, but …
View article: Production and nutrient composition of forage legume fractions produced by juicing and leaf stripping
Production and nutrient composition of forage legume fractions produced by juicing and leaf stripping Open
The large-scale import of soybean products into the EU decreases the self-sufficiency of livestock production. The fractionation of grassland forage crops presents an opportunity to locally produce protein-rich feed for monogastrics. Two p…
