Impact statement

Based on yellow pea samples and associated management details from farms in Montana and North Dakota, water limitation may be the most important growing condition that increases pea protein in dryland pulse crop production. The use of granular rather than seed-coat inoculant correlated with higher pea protein under severe drought conditions. Other than a boost in protein with sulfur fertilization in moderate drought condition, starter phosphorus, potassium, and sulfur applications were not correlated with pea protein.
