“…The water uptake which was equal to crop transpiration rate was also estimated by using continually measurements of the water volume supplied to the crop and the water collected by the drainage system in each treatment by means of a simplified water balance model (as cited in Tsirogiannis et al, 2010). Water use efficiency was calculated as the ratio of the total yield to the total applied irrigation solution (Meric et al, 2011).…”

Three irrigation frequencies were applied on a soilless cucumber crop, in a greenhouse located in the coastal area of southern Cyprus. Irrigation scheduling was based on solar radiation and performed whenever accumulated solar radiation energy outside the greenhouse reached 1.3 MJ m-2 [High Irrigation Frequency (HIF)], 1.9 MJ m-2 [Medium Irrigation Frequency (MIF)] and 3.0 MJ m-2 [Low Irrigation Frequency (LIF)]. The amount of water applied was 0.192 Kg m-2, 0.288 Kg m-2 and 0.448 Kg m-2 for high, medium and low irrigation frequencies, respectively. Appropriately, the total volume of water applied was identical in each of the three cases. In order to study the effects of irrigation frequency on cucumber crops, multiple measurements were taken; the fresh and dry weight of plant organs (i.e. leaves, stem and fruit), marketable fresh yield production, and microclimate variables for a 75 day period, beginning in April and ending in June. The results revealed that the irrigation frequency did not influence the cucumber crop’s growth and production. Plants at LIF were facing water stress conditions, as estimated from leaf temperature and stem micro variation measurements. However, HIF increased the transpiration rate of the plants, resulting in less water and nutrient losses.

“…Deficit irrigation management is possible when crop production function is estimated. When properly applied, the technique shows great potential to increase water use efficiency (Meric et al, 2011), especially in areas of low water availability (Lorite et al, 2007). The deficit irrigation could be used for tomato without reduction in yield and also with increase in fruit quality parameters, such as the content of sugar and antioxidants moieties (Favati et al, 2009).…”

The influence of irrigation depth was evaluated on tomato crop hybrid Debora plus for salad in a field experiment in split-block design with five treatments (irrigation depth of 40, 60, 80, 100 and 120% of crop evapotranspiration -ETc) and four replications. During the experiment, ten plant samples were collected to determine phytomass and leaf area to estimate plant growth parameters for different depths of irrigation. Results showed maximal growth between 70 and 80 days after transplanting in all treatments. Increase in irrigation depth above 80% of ETc increased crop growth rate (CGR), leaf area index (LAI) and total production of tomato fruits, although same commercial fruit yield was obtained with the lower depths. Therefore, an increase in depth of irrigation above 80% of ETc promotes higher water and energy consumption, without providing an increase in commercial yield of tomato fruits.

Para cada tratamento foram realizadas dez coletas de plantas visando à determinação da fitomassa e da área foliar. Foi possível constatar que o acúmulo máximo de fitomassa ocorreu entre 70 e 80 dias após o transplante, em todos os tratamentos. O aumento na quantidade de água aplicada acima de 80% da ETc resultou em maior crescimento vegetativo do tomateiro e causou incremento na produção total de frutos, porém com a mesma produção comercial de frutos obtida nos tratamentos com menores lâminas aplicadas. Conclui-se que o aumento na quantidade de água aplicada via irrigação, acima de 80% da ETc, promove maior consumo de água e energia sem, no entanto, proporcionar aumento na produção comercial de frutos do tomateiro.

“…Once again, it proved that the previously reported benefits of fertigation apply only for recirculating systems. Only in closed systems, it is possible to reduce water consumption by 15-35% and to limit losses of nutrient solution by 15-67% [35,36].…”

Soil Contamination - Current Consequences and Further Solutions

View full text Add to dashboard Cite

Contamination of the soil environment mostly is identified with industry, especially mining and road transport. Unfortunately, also in the commercial horticulture, there are numerous problems concerning the contamination of soils and substrates. Sources of contamination can be fertilizers and waste materials polluted by heavy metals, particularly by cadmium. In the greenhouses where traditional methods of cultivation are used, the soil pollution due to the application of excessively high doses of fertilizers constitutes an environmental hazard. Much faster similar effect occurs in greenhouses where an open system of fertigation is used. In addition to mineral impurities, organic compounds emitted by the plant or that are formed during decomposition of organic matter are the problem. This phenomenon is called allelopathy. In practice, it concerns the monoculture and perennial crops and especially is observed in nurseries, orchards, plantations of berries and asparagus. For this reason, in the later section, the soil sickness, replantation problem and toxicity of mulches in green areas are also discussed.
