The triticale <br />will act as a companion cover crop whenever the planting of the alfalfa occurs in the fall. <br />Seed Mix #7 - Recommended Varieties <br />Alfalfa - Lahontan (Vernal, Ladak 65, Dawson or other recommended flemish varieties)* <br />The Morgans also would like to be able to use AV120 and SS 120 alfalfa (Medicago Sativa) from <br />Arkansas Valley Seed Company. <br />Other varieties may be used, upon approval with the landowner and the NRCS. New species <br />may be developed which are better suited to these site conditions and soils. <br />5.4 Irrigated Cropland Seeding Procedures <br />The optimum seeding season for establishment of Irrigated Cropland (alfalfa) is in the late <br />summer, around August 21, provided adequate irrigation water is available. This will allow for 6- <br />8 weeks of growth, which is enough time to establish an adequate stand capable of over- <br />wintering. During seeding of all Irrigated Croplands (IC) with the permanent seed mix, an annual <br />companion grain cover crop of Triticale will be used at the rate of 40 Ibs per acre. This will <br />provide rapid growth so little topsoil is lost to erosion while at the same time providing some <br />nitrogen and organic matter to the soil. This practice will help rejuvenate soils that have been in <br />stockpiles for long periods of time. <br />At times, the size or shape of the retopsoiled areas and shape of the reclaimed area in relation <br />to a management unit may be insufficient to warrant establishment of the perennial irrigated <br />pasture species initially. When this occurs, and the period before establishment of permanent
