Cerium oxide nanoparticles (CeO2 NPs) have been shown to have significant interactions in plants. Previous study reported the specific-species phytotoxicity of CeO2 NPs by lettuce (Lactuca sativa), but their physiological impacts and vivo biotransformation are not yet well understood, especially in relative realistic environment. Butterhead lettuce were germinated and grown in potting soil for 30 days cultivation with treatments of 0, 50, 100, 1000 mg CeO2 NPs per kg soil. Results showed that lettuce in 100 mg·kg-1 treated groups grew significantly faster than others, but significantly increased nitrate content. The lower concentrations treatment had no impact on plant growth, compared with the control. However, the higher concentration treatment significantly deterred plant growth and biomass production. The stress response of lettuce plants, such as Superoxide dismutase (SOD), Peroxidase (POD), Malondialdehyde(MDA) activity was disrupted by 1000 mg·kg-1 CeO2 NPs treatment. In addition, the presence of Ce (III) in the roots of butterhead lettuce explained the reason of CeO2 NPs phytotoxicity. These findings demonstrate CeO2 NPs modification of nutritional quality, antioxidant defense system, the possible transfer into the food chain and biotransformation in vivo.

“…The evaluation of RCI in function of soil boron application is justified by the fact that boron is related to the nitrogen assimilation process (N) by plants (Ouzounidou et al, 2013). This is because boron can optimize the synthesis of nucleic acids and proteins, increasing photosynthetic activity and carbohydrate metabolism (Malavolta, 2006).…”

The objective of this study is to evaluate the effects of sources and doses of boron on the physiological quality and production yield of Phaseolus vulgaris grown using a central pivot irrigated system on a tropical climate region. The experiment was a 4x5 factorial design representing four sources of boron (boric acid, borax, borogran and FTE BR 12) and five boron doses (0, 1, 2, 3 and 4 kg ha -1 ), with four replications. The following parameters were measured: relative chlorophyll index, transpiration, CO 2 internal concentration, stomatal conductance, net photosynthesis, B content, grain yield and economic analysis. The relative chlorophyll index (RCI) of plants showed no significant effects at both 28 and 46 days after emergence (DAE). The extraction order of boron was boric acid > borax > FTE BR12 > Borogran. The application of boron did not affect the physiological quality (stomatal conductance, transpiration and internal concentration of CO 2 ). However, the net photosynthetic rate was lower when boric acid was applied in relation to other sources. The maximum production (4,446 kg ha -1 ) was obtained using 1.35 kg ha -1 of B with the use of boric acid. However, according to an evaluation of economic viability, it is observed that there are economic differences among sources of boron and evaluated doses. The application of 4 kg ha -1 of borax provides the highest economic return.

In addition, the risk of leaching of nitrate nitrogen increases because application rate in many vegetable growing areas often exceed crop demand and it is accompanied with intensive soil washing (Candido et al, 2009).…”

“…This is especially important for environment protection from nitrogen pollution, especially in intensive agriculture, where water and nutrients are the most utilized resources for obtaining greater yields per unit area. A number of reports (Li et al, 2001;Zhu et al, 2005;Stagnari and Pisante 2012;Ouzounidou et al, 2013) indicated that nitrogen is one of the major potential environmental contaminant and, hence, increasing nitrogen use efficiency is central to environmental responsibility and agricultural sustainability (Fageria and Baligar, 2005). Therefore, proper fertilizer application in right time, right rate and right place (Roberts, 2008) will increase crop yields and nutrient efficiency, as well as farmer benefits and protection of environment.…”

The pepper producers in the Republic of Macedonia have used drip irrigation systems to increase yield in recent years, but more research is still needed, related to irrigation scheduling and precise requirement of nitrogen fertilizer to maximise pepper yield. Therefore, a two year experiment was conducted in a plastic house to determine the nitrogen fertilizer use efficiency (NFUE) and yield potential of pruned pepper as affected by irrigation and fertilization regime. Four experimental treatments were applied in this study. Three of the treatments were drip fertigated (DF 1 , DF 2 , DF 3 ), while the fourth treatment was furrow irrigated with conventional fertilization (Ø B ). The labelled urea with 1% concentration of a stable isotope of nitrogen ( 15 N) was applied for determination of NFUE. The results of this study clearly showed that increased NFUE and pepper yield depend on irrigation and fertilization regime. Namely, NFUE was significantly increased with the application of nitrogen fertilizer through drip irrigation system as compared to conventional fertilization with furrow irrigation. Also, drip fertigation frequency positively affects percentage increase of NFUE. Furthermore, our results showed that drip fertigation treatments resulted in significantly higher pepper yields in comparison to conventional fertilization. Also, drip fertigation frequency at four and two days (DF 2 and DF 1 ) resulted in higher yields when compared with drip fertigation scheduled by using tensiometers (DF 3 ). Generally, to reach acceptable pepper yield with high NFUE, we recommend drip fertigation with a frequency of two to four days combined with two main shoots of pruned pepper in order to increase farmer's income and to minimize the environmental impact.
