Far red light interception increased, and transmission of photosynthetic photon flux (PPF) decreased as dye concentration increased. Light transmitted through photoselective panels reduced height of bell pepper and watermelon seedlings by ≈ 30%. The shoot dry weight of plants was also reduced with increasing dye concentration. Rigid panels with a higher dye concentration were slightly more effective in reducing plant height but the reduction in PPF with increasing dye concentration can adversely affect plant growth and development. Based on initial results, photoselective, polyethylene films were produced with a dye concentration that resulted in 75% light transmission (phytochrome photoequilibrium of 0.80) for further testing. The response of cucumber, tomato, and bell pepper seedlings was evaluated under photoselective films with two different types of dyes that reduced light transmission by 75%. Cucumber seedlings were more responsive to filtered light than tomato or pepper seedlings. Developmental rate, measured as the rate of node production, was not affected. Photoselective films reduced total shoot dry matter of cucumber and bell pepper. Smaller plants as opposed to a reduction in dry matter production primarily caused the shoot dry weight reduction under the photoselective filters. Significant reduction in stem elongation can be achieved by exclusion of FR light at the end of the day by covering west and south facing walls of the chambers or by exposing plants to photoselective films at the end of the day. However, continuous exposure of the plants to the photoselective films was most effective in reducing stem elongation.","PeriodicalId":169819,"journal":{"name":"Journal of Vegetable Crop Production","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126369001","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}

Optimal management of N and irrigation is important to improve N uptake efficiency, and minimize N losses while maintaining high yields and quality. Management of these inputs becomes a challenge in sandy soils, which are vulnerable for leaching of water and soluble nutrients. Real-time continuous monitoring of soil water within and below the rootzone is important to improve scheduling of irrigation to ensure adequate supply of water for plant growth and tuber production, without the risk of excessive leaching of water below the rootzone, which can contribute to leaching of soluble nutrients. Field studies conducted at various production regions show that a combination of pre-plant and in-season N application is necessary to increase N uptake efficiency, and produce high yields of high quality potatoes. The rates and timing of application of pre-plant and in-season N appeared to vary to some extent in different production regions. Excessive N applications contribute to excess vine growth at the expense of the tuber production. The production conditions must be favorable for translocation of N from vines to the tubers. Maintaining adequate supply of N availability in the soil is particularly important through the tuber bulking stage.","PeriodicalId":169819,"journal":{"name":"Journal of Vegetable Crop Production","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115339591","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}

Green peppers (Capsicum annuum L.), cv. Bellboy, were grown in field lysimeters filled with a sandy loam soil. The lysimeters were covered with plastic sheets to prevent rainfall/surface water entry. Water having salinities of 1, 3, 5, and 7.5 dS·m−1, was applied through the bottoms of the lysimeters, and steady-state water tables were maintained at 0.45 or 0.9 m from the surface. The soil solution salinity in the soil profile remained less than 3.5 dS·m−1 during the growing season, and there was no appreciable increase in soil solution salinity in the root zone. Five rates of fertilizers were applied on the soil surface. The highest yield was obtained when all three nutrients, N, P, and K were applied at the recommended rates. The highest rate of N decreased pepper yield due to vigorous vegetative growth. Although the rate of P did not significantly increase yield when applied with K only, the yield significantly increased (P ≤ 0.05) when P was applied with K and N. Average yield ranged from 706 to 1,229 g/plant. There was no interaction of fertilizer with water table depth or irrigation water salinity. It appears that water with salinities up to 7.5 dS·m−1 could be used to supplement the stored fresh water in the soil profile using a subirrigation system for growing moderately salt-sensitive crops such as green peppers.","PeriodicalId":169819,"journal":{"name":"Journal of Vegetable Crop Production","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126443715","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}

Therefore water saving practices will have to be adopted. This experiment was carried out to compare deficit irrigation (DI) with partial rootzone drying (PRD) for their effects on the processing tomato (Lycopersicon esculentum Mill.) cv. Petopride. The treatments were: full watering of both sides of the root system (RS) at each irrigation as control (C), half of irrigation water in C divided equally to both sides of the RS with each watering (DI), and half of irrigation water in C given only to one side of the RS with each irrigation (PRD). Photosynthetic rate, transpiration, stomatal conductance, and leaf water potential were measured on five occasions, and were found to be the same among treatments. Total fruit fresh mass was lower in DI and PRD than in C, but total fruit dry mass was the same among treatments. Irrigation use efficiency was higher in DI and PRD than in C. Vegetative fresh mass was not affected by treatment. However, compared with C plants, vegetative dry mass was higher in DI and PRD plants. Percentage of dry mass allocated into roots was the same among treatments, but a higher allocation was into stems and leaves in DI and PRD plants than in C plants. This was the opposite for the fruit. Total fruit fresh mass was affected by the quantity of irrigation water applied, but not by the volume of soil wetted. Both DI and PRD treatments were found to be feasible water-saving practices for ‘Petopride’.","PeriodicalId":169819,"journal":{"name":"Journal of Vegetable Crop Production","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130812761","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}
