Calculating on a weight basis: <br /> 30 PLS seeds/ft of row <br /> 470 feet/row <br /> 1 pound of Calamagrostis/ 669,650 seeds <br /> PLS factor of 0.15 <br /> 454 grams/pound <br /> 30 PLS seeds/ ft of row (470 feet/row) (1 pound of Calamagrostis/ 669,650 seeds) <br /> (454 grams/pound) divided by 0.15 PLS = 64 grams per row <br /> RESULTS <br /> As of today's date, May 20, 1999, there appears to be no emergence from any of the four <br /> plantings of the Calamagrostis. Considering the relatively good germination results which <br /> were obtained from greenhouse trials and from the Colorado Seed Lab (see attached <br /> report), actual field emergence results are very disappointing. <br /> CONCLUSIONS <br /> The size of Calamagrostis purpurascens seed and its fluffy characteristics make it a <br /> challenge to work with as far as mechanical application is concerned. The particular seed <br /> lot which was collected and cleaned had good germination in greenhouse trials performed <br /> by the UCEPC and from results provided by the Colorado Seed Lab. However, <br /> conventional planting and establishment methods appear to have had little or no success in <br /> seed emergence. Although the months of April and May have been cool, if no <br /> establishment success is identified by the second week of June, the project will be <br /> terminated. <br /> If an additional planting is done, I recommend a surface or near surface seeding <br /> application followed with light harrowing and possible mulching. This seed bed should <br /> then be watered almost continuously for 7-10 days such that no dry down occurs on the <br /> soil surface. This should promote emergence of any seed which is viable and has no <br /> dormancy. <br />
