In an era of environmental sensitivity, enrichment of soils with green manures and cover crops may reduce the dependence on these fertilizers while maintaining and enhancing crop yields. The objectives of this research were to determine (1) if supplemental nitrogen (N) at 60 or 120 kg · ha−1 following winter cover crops of wheat (Triticum aestivum L.) or crimson clover (Trifolium incarnatum L.) affect yield of tomato (Lycopersicon esculentum Mill.) and snap bean (Phaseolus vulgaris L.) grown in rotation; and (2) the distribution and retention of soil nitrates in the soil profile as affected by N fertilization and cover cropping. ‘Mountain Pride’ fresh market tomato and ‘Strike’ snap bean were grown in rotation for four years. Clover and wheat cover crops increased total marketable yield of ‘Mountain Pride’ tomato in one out of four years. Total marketable tomato yield increased as fertilizer N increased to 60 kg · ha−1 in two out of four years and with 120 kg · ha−1 in one out of four years. N did not interact with cover crops to affect yield. ‘Strike’ snap bean marketable yield summed over all years was 60% lower in clover plots compared with fallow. Total marketable snap bean yield increased with 60 kg N · ha−1 in one out of three years but was unresponsive to N in two out of three years. Soil nitrates to 1.2 m depth were higher after clover and wheat than after fallow. Nitrate level was highest in soil with clover and 120 kg N · ha−1. In all cover crop or fallow plots, as fertilizer N application levels increased, the soil nitrates also increased. Cover crops or fertilizer N application did not increase the retention of residual nitrates in the 1.2 m soil profile depth after four years of cropping.","PeriodicalId":169819,"journal":{"name":"Journal of Vegetable Crop Production","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128204648","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Overall, total yield was not affected by seeding rate or seeder; however, plant population produced a shift in yield among grades. Generally, yield of extra-large roots was greatest on plots with lower plant populations. Medium and cull yields were greater on plots with the higher plant populations (bulk seeder with 100% viable seed and precision seeder with 56-mm spacing or 2-row configuration).

Soil content of plant nutrients is low, with high content of calcareous materials, particularly calcium carbonate. The soils are moderate to shallow in depth, are sandy, derived from sedimentary rocks, and transported by sandstorm. Two production methods were developed for vegetable crop cultivation in Kuwait; indoor and outdoor systems. The productivity of the indoor system is very low (between 1 to 3 T/ha) and the production cost is high due to gaps in technology transfer, inefficient management, and widespread damage by insects and diseases. All vegetable crops grown in outdoor field cultivation are exposed to harsh climatic conditions and consequently their productivity is even lower (between 0.10 to 0.55 T/ha) and the quality is inferior. The research activities and scientific findings in Kuwait have not been able to generate or adapt any technology locally for appropriate crop species/varieties, efficient and significant use of soil and water research, crop nutrition, pest management and marketing of produce.","PeriodicalId":169819,"journal":{"name":"Journal of Vegetable Crop Production","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125035419","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Double drills offer higher yields in some cases, but may be difficult to maintain because of erosion of the sides of the beds from heavy rainfall. A series of 18 plantings was made to compare stands of cabbage and broccoli, expressed as percent of viable seed planted, from single and double drills over a total of six months. Stand counts were taken approximately 10–20 days after planting. The crops were not taken to yield. Heavy rainfall did not occur after any of the 18 plantings, so serious bed erosion did not occur.

Concentrations of CO2 inside the vessels were monitored until equilibrium was reached. Light compensation point was reached at $2.0 μmol · m−2 · s−1 for photoautotrophic seedlings and at $4.0 μmol · m−2 · s−1 for photomixotrophic seedlings. Therefore, in the long-term storage experiment, seedlings were stored for 4, 8, or 12 weeks at 1 ± 0.35°C in darkness or under 3 μmol · m−2 · s−1 constant PPF (average light compensation point) of white, red, or blue light. Variable to maximal chlorophyll fluorescence (Fv/Fm) of leaves decreased as storage time increased, regardless of media composition. Illumination during storage was necessary to maintain dry weight and regrowth potentials of in vitro seedlings. All photo-autotrophic seedlings stored in darkness were of poor quality and died when transferred to the greenhouse. Seventy-five percent of dark-stored photomixotrophic seedlings survived storage for 12 weeks but declined in appearance, dry weight, total soluble sugars (TSS), and chlorophyll fluorescence. Red light during storage increased seedling dry weight, TSS, and regrowth potential. Supplying 2% sucrose in the culture medium increased dry weight and maintained overall seedling quality during irradiated storage.","PeriodicalId":169819,"journal":{"name":"Journal of Vegetable Crop Production","volume":"214 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132617072","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
