, 2009). OxO was first isolated and characterized from wheat ( Triticum aestivum ) ( Lane et al., 1993 ). It catalyzes the oxidation of oxalic acid by molecular oxygen to form carbon dioxide and hydrogen peroxide (H 2 O 2 ). Researchers have found that

the yield of the next vegetable crop grown due to N immobilization. Although winter grass cover crops, such as wheat ( Triticum aestivum ) or winter rye ( Secale cereale ), are often used in vegetable NT production systems to reduce soil erosion and to
Various fall-planted cover crops were evaluated for their influence on weeds and yield of ‘Midway’ and ‘Guardian’ strawberries (Fragaria x ananassa Duch). Rye (Secale cereale L. ‘Wheeler’) and wheat (Triticum aestivum L. ‘Yorkstar’) provided greater early season weed suppression than barley (Hordeum vulgare L. ‘Barsoy’). A high cover crop seeding rate increased weed suppression. Fruit yields were not reduced significantly by any of the cover crops.
Potato (Solanum tuberosum L.) is one of the major food crops of the world and ranks fourth after rice (Oryza sativa L.), wheat (Triticum aestivum L.), and corn (Zea mays L.) in production. Potato production is concentrated in the temperate zone and in tropical areas, especially at higher elevations. It is of vital interest to study cultural practices associated with potato due to the global importance of this crop. In particular, emphasis will be placed on methods to propagate the potato.
`Yecora Rojo' Wheat (Triticum Aestivum L.) And `Florida Petite' Tomato (Lycoper-Sicon Esculentum Mill.) Plants Were Grown In Monocultured Or Intercropped Recirculating Hydroponic Systems To Determine Whether Plant Growth Or Yield Would Be Affected By Intercropping. Mean Fruit Weight Was Slightly Lower (12%) For Intercropped Than For Monocultured Tomato Plants. The Number Of Tillers Per Plant Was Slightly Lower (7%) For Wheat, And Grain Dry Weight Per Plant And Mean Seed Dry Weight Were Slightly Higher (14% And 15%, Respectively) For Intercropped Than For Monocultured Plants. A Lettuce Seedling Bioassay Showed No Evidence Of Allelopathic Compound Accumulation In Monocultured Or Intercropped Hydroponic Systems.
To test the usefulness of methanol treatments in enhancing yield and drought tolerance, we applied methanol with and without nutrients to a wide range of crops across California: lemon (Citrus limon L.), creeping bentgrass (Agrotis palustris Huds.), romaine lettuce (Lactuca sativa L.), carrot (Daucus carota L.), corn (Zea mays L.), wheat (Triticum aestivum L.), pea (Pisum sativum L.), and radish (Raphanus sativus L.). Environments included greenhouse and field tests in coastal, inland-valley, and desert locations. Methanol did not increase the yield or growth of any crop. In some cases, methanol caused significant injury and decreased yield.
Tomatoes (Lycopersicon esculentum Mill.) were grown in conventional tillage (CT), rye (Secale cereale L.) mulch no tillage (RNT), and wheat (Triticum aestivum L.) mulch no tillage (WNT). Either germinated seeds (GS) or raw seeds (RS) were fluid drilled on several dates in 1981 and 1982. Tomato stands in no tillage (NT) generally were equal to or higher than in CT, and stands improved with later plantings in each year. Plant stands were unaffected by GS and RS. Time to 50% emergence (T50) was up to 4 days less in NT than in CT and 2 to 3 days less from GS than RS. Yields with CT were twice as high as those with NT for early planting dates. Yields decreased in CT with successive planting dates to levels equal to NT plantings. Use of GS increased fruit yields as compared to RS, regardless of the planting date.
