Alfalfa is well known for enhancing yield of grass crops like corn that follow it in rotation. Alfalfa benefits are due not only to the addition of biologically fixed nitrogen (N), but also to rotation effects including reduced disease and weed pressure and increased soil organic matter and aggregation of soil particles. Taking advantage of alfalfa's rotational benefits reduces fertilizer and pesticide costs and boosts yields.

The cold and wet growing season for Minnesota delayed the growth and development of corn such that growers may consider selecting earlier maturing hybrids for 2005 compared with maturities that they have normally been growing. The subject of this newsletter is to evaluate the yield and drying cost tradeoffs of planting earlier maturing corn hybrids.
Normal Corn Development Compared With 2004
Calendar dates for developmental events for corn in Minnesota for the past five years compared with this past year are given in Table 1.
