Effect of Boron Fertilization on Alfalfa Production

Effect of Boron Fertilization on Alfalfa Production, 1998 This research in northwestern Montana is evaluating the potential benefits to boron (B) applied across different phosphorus (P) fertility levels for intensively managed irrigated alfalfa. It was initiated in 1997 and will continue through 1999. Annual rates of B at 0, 1, and 2 lb/A are being evaluated across P2O5 rates of 0, 40, and 80 lb/A.

1997 Annual Interpretive Summary

Effect of boron fertilization on alfalfa production, 1997

In a new project initiated in 1997 in northwestern Montana, three rates of boron fertilization are being evaluated across three rates of P for irrigated alfalfa production. First year yields (3 cuttings) averaged above 6 tons/A, but there was no response in this initial year to either nutrient applied. This research will be continued an additional two years to document potential long-term benefits to B and P fertilization for intensively managed irrigated alfalfa. MT-13F
