indicated that delaying pearl millet planting 10-14 days after seedbed

preparation and killing the existing vegetation at planting would be feasible.

 In 1992, a field demonstration plot of pearl millet was planted in 18 and

 36 inch row spacing and then treated with paraquat at 0.5 lb/A within 48 hours

 of planting. Weed control observations, 14-21 days after planting, showed

 overall weed control at 95%, which included weeds such as Texas panicum,

 crabgrass, Smallflower morningglory, and Palmer amaranth.

 At approximately 21 days after planting, canopy closure (overlapping the row

 middles) of pearl millet planted in 18 inch rows occurred and provided shade and

 competition for weeds for the remainder of the growing season. Pearl millet

 planted in 36 inch rows required about 4 weeks after planting for canopy closure,

 which provided an opportunity for some weeds to emerge and grow in the row

 middles. The use of stale seedbed techniques utilizing Gramoxone Extra was very

 effective and economical as a weed management program in pearl millet. A second

 demonstration plot, in 1992, indicated that pearl millet planted in a stale

 seedbed and treated with Gramoxone Extra at 0.25 lb/A at planting, followed by

 Atrazine at 0.75 lb/A as an early post-emergence treatment was also very

 effective in controlling a broad spectrum of annual weeds and that 18 inch row

 spacing provided more shade and competition to weeds than 36 inch row spacing.

 In 1993 and 1994, experiments evaluated selected post-emergence herbicide

treatments on pearl millet grown in conventional and stale seedbed (Tables 7, 8,

9 and 10). In 1993, the control of all weeds generally ranged from good to

excellent. Some treatments caused slight to moderate injury to pearl millet, but

pearl millet recovered by maturity. A direct comparison between conventional and

stale seedbed results could not be made because these were separate experiments,

but the data in Tables 7 and 8 indicate very little difference in the level of

weed control between seedbed preparation and specific herbicide treatments.

Yield data were not collected in 1993 because of severe bird damage.

 In 1994, data in Tables 9 and 10 indicate a much higher level of weed

control in stale seedbed than in the conventional seedbed. Again, statistical

comparison could not be made because these are separate experiments. But, the
