-USE = overseeding pasture 5-10Ibs
Devine Little Burr Medic - Answer- -blacklands ecoregion
-soil type : clay loam (well drained)
-soil pH = 6-8
-limited production (1500-4000)
-Use = OVERSEEDING 3-5Ib
Berseem Clover - Answer- -soil type = loam, clay loam
-soil pH = 6-8
-low bloat potential
-tolerates flooding and wet soils ; LOW DROUGHT tolerance
-lacks reseedind potential and cold tolerance
-best use south I-20
White Clover - Answer- -latest variety out of Overton "Neches"
-best adpated to bottomland sites
-generally a reseeding annual in east Texas
-late spring forage production
-economical establishment
Blackhawk (Apache) Arrowleaf Clover - Answer- -soil type = sandy loam
-soil pH = 6-7
-fungal and virus tolerance
-most productive and latest maturing of the clover varaties
-seeding rate = 8-10
bloat potential : LOW
, Crimson Clover - Answer- -best combination of cold tolerance and early spring forage
production for east Texas
-can be managed for reseeding but has less hard seed than arrowleaf, white or rose
-standard cultivars flower in mid-April and allow early grass production
Rose Clover - Answer- -overton R18 developed at Overton
-high hard seed percentage
-planting rate can be reduced from 16 to 18 Ib for more economical establishment
-early spring forage production not as good as crimson
-not adapted to wet, poorly drained sites
Ball Clover - Answer- -soil type = loam, clay loam
-soil pH = 6.5-8

-high bloat potential
-Use : overseeding pastures 2-3Ib
-excellent reseeding
Hairy Vetch - Answer- -broad soil adaption
-sandy loam to clay
-will tolerate high pH of blacklands ecoregion
-soil pH : 5.5-8
-USE = overseeding pastures 20-25Ib

-reseeding not reliable
Alfalfa - Answer- -well drained soil sites
-grows best at soil pH 6.5-7
-grazing initiated at bloom
-plan to replant 5-6yrs
-bloat potential : High
National Survey Attitudes Towards Clovers Results Concerns: - Answer- -seed cost
