The influences of different N fertilization rates and soil salinity levels on the growth and nitrogen uptake of cotton was evaluated with a pot experiment under greenhouse conditions. Results showed that cotton growth measured as plant height was significantly affected by the soil salinity and Nsalinity interaction, but not by N alone. Cotton was more sensitive to salinity during the emergence and early growth stages than the later developmental stages. At low to moderate soil salinity, the growth inhibition could be alleviated by fertilizer application. Soil salinity was a dominated factor affecting cotton's above-ground dry mass and root development. Dry mass of seed was reduced by 22%, 52%, and 84% respectively, when the soil salinity level increased from control level of 2.4 dS m −1 to 7.7 dS m −1 , 12.5 dS m −1 and to 17.1 dS m −1 , respectively. N uptake increased with N fertilization at adequate rates at both low and medium soil salinities but was not influenced by over N fertilization. At higher salinities, N uptake was independent of N rates and mainly influenced by soil salinity. The uptake of K decreased with soil salinity. The concentration of Na, Cl and Ca in plant tissues increased with soil salinity with highest concentrations in the cotton leaf.

“…Fageria and Baligar (2005) described five definitions of calculating NUE in crops, which are grouped or classified as agronomic efficiency (AE), physiological efficiency (PE), agro-physiological efficiency (APE), apparent recovery efficiency (ARE) and utilization efficiency (UE). The increase in NUE and grain yield mainly depend on timely planting, proper tillage and optimum nitrogen rate and management (Zemenchik and Albrecht, 2002). The main goal in improving nitrogen utilization, optimizing the fertilization and reducing the risk of surface and belowground water resources contamination is to better understand the plant nitrogen response (Mahler et al, 1994).…”

In recent years, quinoa (Chenopodium quinoa Willd.) has attached the interest as a multi-purpose crop. A 3-year field experiment was conducted to determine the effects of tillage systems and fertilization on nitrogen uptake and use efficiency of quinoa crop. The experiment was laid out in a split-plot design with two replicates, two ) were found in N2. Nitrogen harvest index and nitrogen utilization efficiency were up to 60% lower and 40% lower, respectively, in inorganic treatments than in the control. Rates of nitrogen higher than 100 kg N ha -1 (N1) did not increase the nitrogen agronomic efficiency. Regarding apparent nitrogen recovery efficiency, the higher values observed under inorganic fertilization and being greater than 100%. The highest rates of change of nitrate reduction in soil (-0.108 to -0.188 N% day -1 ) and nitrogen increase in plant (0.025 to 0.027 N% day -1 ) were observed under N2 treatment. As a conclusion, quinoa has a high capacity to take up nitrate from the soil, but presents lower nitrogen remobilization from the vegetative parts into the seeds under high nitrogen supply.

Ideal nitrogen (N) management for turfgrass supplies sufficient N for high‐quality turf without increasing N leaching losses. A greenhouse study was conducted during two 27‐wk periods to determine if in situ anion exchange membranes (AEMs) could predict nitrate (NO3–N) leaching from a Kentucky bluegrass (Poa pratensis L.) turf grown on intact soil columns. Treatments consisted of 16 rates of N fertilization, from 0 to 98 kg N ha−1 mo−1 Percolate water was collected weekly and analyzed for NO3–N. Mean flow‐weighted NO3–N concentration and cumulative mass in percolate were exponentially related (pseudo‐R2 = 0.995 and 0.994, respectively) to AEM desorbed soil NO3–N, with a percolate concentration below 10 mg NO3–N L−1 corresponding to an AEM soil NO3–N value of 2.9 μg cm−2 d−1 Apparent N recovery by turf ranged from 28 to 40% of applied N, with a maximum corresponding to 4.7 μg cm−2 d−1 AEM soil NO3–N. Turf color, growth, and chlorophyll index increased with increasing AEM soil NO3–N, but these increases occurred at the expense of increases in NO3–N leaching losses. These results suggest that AEMs might serve as a tool for predicting NO3–N leaching losses from turf.
