In a leased alfalfa field, which hay harvested at an early bloom stage will be highest in crude protein?

Hay harvested in June
Hay harvested in July
Both will be the same
I cannot determine without more information

The correct answer is: Hay harvested in June

Harvesting alfalfa hay at the early bloom stage typically yields higher crude protein levels when done earlier in the growing season, such as in June. During this time, the plant is still in its vegetative growth phase before the energy and nutrients start to be directed towards seed production as it matures. As the summer progresses and the plants continue to develop, particularly when harvested in July, the foliage will often lose some of its protein content as more energy is allocated to seed formation and the plant matures. This is because the protein concentration in forages generally decreases as the plant matures past the early bloom stage. Therefore, early harvesting in June is more beneficial for maximally retaining crude protein levels.
