Abstract

To study the effects of SOWING DEPTH along with sowing seeds with and without husk on soil SEED BANK as well as natural REGENERATION of ANNUAL MEDICs, this experiment was conducted during 2001 and 2002 growing seasons. The experimental treatments were arranged in factorial-split plots based on a complete randomized block design with 3 replications. Six ANNUAL MEDIC cultivars were assigned to the main plots were the SOWING DEPTHs of 2, 4, and 6cm along with sowing seeds with and without husk were randomly assigned to the sub plots. Sowing plants at 2cm depth without husk not only caused a better germination and a uniform establishment, but also resulted in a higher biological yield as well as a richer SEED BANK. Medicago rigidula cv. Rigidula produced the highest biological yield overall sowing treatments among ANNUAL MEDIC cultivars. In the same conditions the highest seed production as well as the richest SEED BANK belonged to Medicago truncatula cv. Caliph. As the seeds were sown deeper, plant density decreased due to a week germination and pasture establishment which led to a lower dry matter and seed production. When the seeds were sown with pods in the same situation the decrements of dry matter and seed were enhanced. Based on the results of this experiment it is suggested to achieve a good pasture establishment in the first year of ley-farming system, all the medic seeds must be scarified before sowing.
