CSU Extension Service-Las Animas <br />County. Trinidad Office (719) 846-6881. <br />SUMMARY AND RESOLUTION OF INTERACTION:Mike returned my call regarding the <br />expected production of an irrigated smooth brome/alfalfa/vetch pasture vs. the same field <br />under dryland conditions. After describing the general location, elevation, and irrigation <br />system of the field he provided the following numbers: Dryland 1-2 T/acre 2T/acre would <br />be under deal conditions- well managed, adequate moisture, stand in good vigor, high % of <br />alfalfa to grass. Irrigated 2-3 T/acre. 3 T/acre would reflect very good conditions- good <br />fertility, good stand vigor, adequate water at proper time of demand, well managed. <br />Translating this into 60 lb. bales on the 10 acres of Chavez's fields would equate to dryland: <br />333-666 bales/10 acres Irrigated: 666-1000 bales/ 10 acres. [Mr. Chavez said he'd been <br />getting 850-950 bales when irrigated (2.5-2.85 T/acre assume 60 Ib. bale)] <br />I asked about reseeding alfalfa into a pasture. Mike said if you aren't managing for a high <br />alfalfa production then you'd likely reseed to alfalfa in the pasture on an 8-9 year basis. He <br />also pointed out that if you don't have a drought resilient variety of alfalfa you may loose <br />quite a bit of the alfalfa stand from not irrigating for a year. Also dryland production was <br />down overall in 1995 due to the late timing of the moisture, dry early late rains. <br />c:\jhb\CSIOI3CT.rsu <br />
