The researchers studied how different amounts of seeds, nitrogen, and zinc affect the quality and yield of fodder maize. They tested various combinations of seed rates, nitrogen levels, and zinc amounts in a field experiment. The results showed that using 75 kg of seeds per hectare produced the highest green fodder yield, crude protein yield, and crude fiber yield. Applying 150 kg of nitrogen per hectare resulted in the highest green fodder yield and better protein content. Adding 10 kg of zinc per hectare also increased green fodder yield and improved protein content.
