( Khurana et al., 1993 ). Properly timed straw mulch can suppress early germinating annual broadleaf and grass weeds and will be sustainable for a long period of time. Mulch, whether living or dead, inhibits the light necessary for weed shoot emergence and

Garlic (Allium sativum L.) has been cultivated in much of the world for millennia. Little scientific research, however, has focused on improving cultural conditions for production in the temperate regions of the northeastern United States, where garlic is gaining importance as a horticultural crop. To study the effectiveness of wheat straw (Triticum aestivum) mulch on garlic, experiments were conducted at the Cornell Univ. research facilities in East Ithaca, N.Y., during the 1993–94 (year 1) and 1994–95 (year 2) growing seasons and at the Homer C. Thompson Vegetable Research Farm, Freeville, N.Y., during the 1994–95 growing season. Two clones, one bolting and one nonbolting, were studied in year 1, and four varieties, three bolting and one non bolting, in year 2. All were fall-planted (mid-October), and mulch treatments were covered with wheat straw early in the following December. Control plots were not covered. The mulch either remained on the crop throughout the growing season or was removed early in the spring to expedite soil warming. This is the common practice among growers who use mulch only for winter protection. The presence of mulch during the winter increased the survival rate. Soil temperatures under the wheat straw were significantly lower during the summer than soil temperatures in unmulched plots, which could have contributed to the increase found in the yield and average bulb size of several of the cultivars. Maintaining the mulch through the entire growing season reduced weed pressure >30%. We found no significant increase in the amount of basal fungal infection. The results indicate that using straw mulch can improve garlic produced in the northeastern United States.

Annual yields of thornless blackberries may be inconsistent due to low winter or early spring temperatures. Under ideal conditions thornless blackberries can produce two or three times more berries per acre and ripen over a longer period of time than the erect, thorny type.

Yields of several thornless blackberry cultivars were improved by using straw mulch. In experiment one standard cultivars were compared to numbered clones. In experiment two Chester, Black Satin, Dirksen and C-65 were compared. Over a six year period, straw increased yields from 1670 to 8300 pounds per acre. Straw mulch appeared to be effective during years where low temperatures did not affect bearing surface.

This study compared shredded newspaper, wheat straw (Triticum aestivum L.) mulch, and bare soil as surface treatments under sweet corn [Zea mays L., var. Saccharata (Surt.)], field corn (Z. mays L.), soybean [Glycine max (L.) Merr.], and processing tomatoes (Lycopersicon esculentum Mill.). In a replicated study with limited mechanical weed control and no chemical weed control in 1990, and no weed control except for the mulch in 1991, the mulches provided a cooler, moister soil environment and effective suppression of most annual and some perennial weeds. The rank order of yields was the same for all three crops in 1990: newspaper mulch > wheat straw mulch > bare soil cover. In 1991 the rank order for yield was: soybeans/newspaper mulch > wheat straw > bare soil (P < 0.01); field corn/newspaper mulch > bare soil > wheat straw (P > 0.10). The straw and newspaper mulches had similar effects on yield, weed control, soil moisture, and soil temperature. They were significantly different from bare soil in many crop and mulch combinations studied. A brief evaluation of high rates of newspaper mulch showed no apparent growth problems for corn and soybeans and no heavy metal accumulation in the soil. Since shredded newspaper from community recycling programs in available at low cost ($40-50/ton vs. $90-100/ton for straw), this material is an attractive soil-management alternative in horticultural and agronomic production systems.

In September of 1991, 1.1 m × 20 cm raised beds were built near Lane, OK. The beds were covered with straw or woven plastic mulch, or were left uncovered. Heavy rains in October left the uncovered beds about 20 cm wide × 13 cm tall. A gully was formed at the end of this field, and soil was deposited across several beds. Strawberry plants were set into all beds in mid-February 1992. At this time, the straw-mulched beds, although settled into an inverted “V” shape, were still about 1 m wide and about 18 cm tall. A very intense hail and rain storm struck the fields on May 13. Most of the hail was about 1.3 cm in diameter. The hail fell for about 30 minutes in early afternoon. The hail was accompanied by about 12.7 cm of rain. The strawberry plants on the woven plastic mulch were almost completely destroyed. The strawberry plants on bare ground were severely damaged by the hail, and their roots were often washed out of the ground. About 85 to 90 percent of these plants died. Strawberry plants on the straw-mulched beds appeared to be less damaged by the hail than other plants, and were not washed out of the ground. About 95% of these plants survived.

Mulching with straw increase soil water content, air relative humidity and air temperature, but decreased soil temperature. Though mulching with straw didn't change light intensity, ginger growth and yield were the same as shading. The growth and yield under shading and mulching with straw were both higher than that of naked soil.
