| الوصف: | The present work summarises the results of the agronomic evaluation of 42 accessions of Paspalum sp. aff. P. plicatulum, with 2 levels of fertiliser (low=pasture establishment and high=crop production) on a red-yellow latosol. Dry matter DM yield in the first 10 months from establishment ranged from 350 to 4400 kg/ha. 47 days from the start of the rainy season, estimated DMY ranged from 400 to 3700 kg/ha. DM yield accumulated during the whole wet season (October-May) ranged from 1 to 18 t/ha. The proportions of dead and green material were variable, with big differences (P<0.001) between accessions. At the end of the rainy period (122 days regrowth), the ratio ranged from 0.3:1 to 25:1 (BRA009652 and 009687 respectively). The mean Crude protein content was 10.3%:tl.21 and the mean intro DM digestibility was 49%±3.7 with a range of 16 units between accessions (40% • 56%). The germplasm tested was free of foliar diseases and insect pests, including spittlebug. Seed yield was variable, ranging from very little to 1200 kg/ha pure seed yield for the most promising accessions. |
