Assessment of the effect of planting date and seed rate on red clover forage yield in Shahrekord region
Journal Title: International Journal of Farming and Allied Sciences - Year 2016, Vol 5, Issue 4
Abstract
Red clover (Trifolium pretense) is a short- lived perennial legume forage plant which is grown in rangeland and field conditions. This study was conducted to assay the effects of planting date and seed rate on red clover forage production in Shahrekord region, in 2007-2008. The experiment was laid out in split plot design with three replications. Main and sub plots included planting dates (27 Aug, 11 and 26 Sep) and seed rates (15, 20 and 25 kg ha-1) respectively. Sowing dates were carried out in 2006 and no remove of forage was taken in the establishment year. Forage was harvested three times in each year. Results showed that the most total dry matter yield belonged to first planting date with 12243.2 kg ha-1 in 2007. It was mainly due to improved production in first cut in compared with others planting dates. In 2008 no significant difference was observed in planting dates, although, the first planting date was the superior with 9926.1 kg ha-1 in two years average. The most and least of total dry matter were 11090.0 and 9003.9 kg ha-1 for 15 and 25 kg ha-1 seed rates respectively in 2007. The decline in production in higher seed rates was appeared in second year as well as two year mean. Mean yield of first year was higher than second with 10354.7 kg ha. In overall, data of this experiment showed that sowing of red clover in 27 Aug to 11 Sep with 15 to 20 kg ha-1 seed rates had higher forage production in this region and the results may be recommendable in similar climatic area.
