“…Similar An/Ci response under different N supplies was described by Chen et al (2013) using CO 2 response curves corroborating that stomatal limitation is not the main reason of reduced mineral by V8 to V14: (i) maize plants partially compensated for low N availability reducing leaf area, and (ii) the leaf N concentrations were able to maintain leaf photosynthetic rates only 10 to 11% lower compared with the middle or high N level classes. These results in are contrast with results by Vos et al (2005) with maize grown in a glasshouse environment, where the primary strategy in maize under N limiting conditions was a reduction of leaf N content and photosynthetic capacity and not a decrease in leaf area expansion. The weak relationship obtained between instantaneous An and CMR readings also suggests that other environmental factors are affecting assimilation rates in addition to leaf N content.…”

“…The N fertilizer was applied as ammonium nitrate (33.5% N) and split in three applications: at pre-planting (April 12th 2011 andApril 11th 2012) (2012) by collecting all ears in the two central rows of each experimental plot (12 period due to a reduction in active leaf area (limited resource capture), and/or (ii) a reduced daily rate of photosynthesis or radiation use efficiency. In maize, Vos et al (2005) discussed that leaf photosynthesis is a more limiting mechanism compared to leaf area growth. In their study, the N concentration of expanding leaves from maize plants at different N supply was well related to light-saturated photosynthetic capacity with a hyperbolic function.…”

There are limited studies about the effect of nitrogen (N) deficiency on leaf growth, N status, and photosynthetic capacity of maize grown under field conditions in a Mediterranean climate. The objective of this work was to evaluate the effect of different levels of mineral N availability on leaf gas exchange parameters of sprinkler irrigated maize. The experiment was conducted in a conventional maize field located in the central part of the Ebro valley (Spain) during two seasons. Using a portable LICOR-6400 equipment, instantaneous measurements and light response curves to gas exchange were conducted in plots with different levels of N supply ranging from deficient (no fertilized) to over-fertilized (300 kg N/ha). In addition to gas exchange measurements, mineral soil N content, chlorophyll meter readings (CMR), leaf N content, and grain yield were measured in the different plots. Results showed that grain yield reached a plateau (14.5 Mg/ha) when the mineral N available was about 179 kg/ha. CMR were linearly and highly related to total N in ear leaves. The relationship between light-saturated leaf photosynthesis measurements and CMR was significant but very weak (R2=0.13) at V8 and V14 stages but increased later in the growing season (R2=0.52). Plants with intermediate levels of N supply (48<CMR<54) tended to have slightly higher assimilation rates than plants with higher CMR readings. As the available N increased, the saturation point, the light compensation point and significant increases of dark respiration rate were observed. Under the conditions of the study, leaf N contents of 1.9% in the ear leaf were enough to maximize leaf assimilation rates with no need to over-fertilize the maize crop.

“…The seed deteriorations caused increased nitrogen content of the seeds, the highest nitrogen percentage was in the 45 hours of deterioration in the second year (1.99%) and the lowest mean was in the non-deterioration treatment in the first year (1.16%) (Table 10). Increasing the amount of nitrogen available to the plant increases the vegetative growth rate in the plant, resulting in a higher percentage of nitrogen in the plant (Vos et al, 2005). The fact that nitrogen is one of the most important elements in increasing the nitrogen content of seed, it seems that increased application of nitrogen fertilizer caused increases in the accumulation of this element in grain.…”

In order to study the effect of seed deterioration, plant density and nitrogen fertilizer application on yield, yield components and somequalitative traits of wheat, a field experiment was conducted in Golestan province of Iran, as split factorial in the randomized completeblock design, with four replications in two growing seasons, 2014-2015 and 2015-2016. The experimental treatments included seedquality at 4 levels (control, 15, 30, and 45 hours of accelerated deterioration), plant density at two levels (350 and 420 plants/m) and nitrogen consumption at 3 levels (recommended rate, 15 and 30 percentages higher than the recommended rate, i.e., 125, 143.75, and162.5 kg N fertilizer ha, respectively). All quantitative traits (plant height, spike length, number of seeds per spike, number of spikeletsper spike, weight of 1000 seed, grain yield, straw yield, biological yield and harvest index) and quality traits (yield and protein content,nitrogen content, yield and starch content) were significantly different in different years. Application of recommended rate of nitrogenfertilizer in the first and the second year resulted in the highest average of number of seeds per spike and spike length. The highestgrain yield was achieved in the recommended and 30% higher than the recommended application rate of nitrogen fertilizer (4061.9 and4166.3 kg/ha, respectively) in the second year. Seed deterioration caused a significant reduction in yield and the yield components, sothe highest level of seed deteriorations in the first and the second years decreased 34.11 and 22.63% of the grain yield compared tothe control treatment. The highest protein content was achieved in the second year with the application of nitrogen 30% higher than therecommended rate (with a mean of 623.6 kg/ha), which increased by about 23% compared to the overall average. Seed deteriorationreduced the starch content, so that the highest mean was in non-deterioration in the second year (68.13%), which increased by 10%compared with that of the overall average. The lowest starch content was achieved at the highest level of deterioration (45 hours) in thefirst year (55.63%). In general, the results indicated that seed deterioration had negative effects on quantitative and some qualitativetraits, but the application of more nitrogen fertilizer and higher plant density reduced the negative effects of deterioration and improvedgrain yield and quality.

Abstract. The nitrogen compound concentration in water is increased by atmospheric-pressure plasma discharge treatment. A rod-to-water electrode discharge treatment system using plasma discharge has been developed by our group to obtain water with a high concentration of nitrogen compounds, and this plasma-treated water improves the growth of chrysanthemum roots. However, it is difficult to apply the system to the agriculture because the amount of treated water obtained by using the system too small. In this study, a multi-spark discharge system (MSDS) equipped multiple spark plugs is presented to obtain a large amount of plasma-treated water. The MSDS consisted of inexpensive parts in order to reduce the system introduction cost for agriculture. To suppress the temperature increase of the spark plugs, the 9 spark plugs were divided into 3 groups, which were discharged in order. The plasma-treated water with a NO 3 -concentration of 50 mg/L was prepared using the MSDS for 90 min, and the treatment efficiency was about 6 times higher than that of our previous system. It was confirmed that the NO 2 -, O 3 , and H 2 O 2 concentrations in the water were also increased by treating the water using the MSDS.
