“…Haile et al [46] reported that different rates of N fertilization significantly increased wheat grain yield, and its maximum was achieved by application of 120 kg N ha −1 (however, optimal yield was not achieved as the response apparently did not plateau out). Litke et al [47] observed a significant wheat grain yield increase up to the rate of 180 kg N ha −1 , and Duan et al [48] up to the rate of 150 kg N ha −1 . According to Ali et al [49], increasing N doses increase plant height as they stimulate the vegetative development, and thus grain yield is reduced.…”

Optimization of fertilization enables to obtain a yield of high quality and quantity, brings economic profits, and reduces environmental threats. The aim of the three-year field experiment was to determine the efficiency of fertilization with a new fertilizer available on the Polish market and containing nitrogen (N) and sulfur (S) in proportions designed for cereals cultivation (30% N and 6% S as ammonium nitrate and ammonium sulfate). Other treatments included no fertilization; fertilization with ammonium nitrate (34% N); fertilization with standard nitrogen and sulfur fertilizer with N supplementation with ammonium nitrate. Nitrogen doses were 150, 200, and 250 kg N ha−1. Sulfur was applied in doses of 30, 40, and 50 kg S ha−1. A beneficial effect of using fertilizer containing N and S in proportions designed for cereals cultivation was observed. The highest mean optimal nitrogen dose and maximum winter wheat yield were recorded for the new fertilizer (217 kg N ha−1 and 8251 kg ha−1, respectively). Sulfur supplementation with the new fertilizer significantly increased apparent nitrogen recovery (mean values 48.9%, 44.6%, and 40.6% for doses 150, 200, and 250 kg N ha−1, respectively), agronomic efficiency (11.1 and 8.6 kg kg−1 N for doses 200 and 250 kg N ha−1, respectively), and physiological efficiency (24.7 kg kg−1 N for dose 200 kg N ha−1).

“…Silva et al [7] did not prove that different N rates affect wheat yield. Duan et al [29] proved that the grain yield of winter wheat under 150 kg N ha -1 increased from 51.4 to 66.6% compared with controls. In the present experiment, intensive mineral fertilization, including the increase in the fertilizer rate by 100%, resulted in an increase in grain yield on average by 0.31 t ha -1 , i.e., by 6.4%.…”

“…Its lack may be an abiotic stress that reduces yield (Zhang et al, 2007). Higher nitrogen application rates increased the accumulation of dry matter (Duan et al, 2014). Aires et al (2006) stated that nitrogen is one of the most important factors affecting plant growth as well as the biosynthesis of secondary metabolites.…”

To evaluate the responses of canola seedlings to different levels of drought stress and nitrogen at different growth stages, a factorial experiment was conducted in a completely randomized design with three replications at the experimental greenhouse of Mohaghegh Ardabili University in 2013. Treatments included three levels of drought stress (30%, 50%, and 70% of FC) and five levels of nitrogen (control, based on soil test results; 25% less than the recommended level; 50% less than the recommended level; 25% more than the recommended level; and 50% more than the recommended level). The recommended level of nitrogen, based on soil test results, was 0.09 g of nitrogen per kilogram of soil. Results showed that drought stress, nitrogen, and their interaction significantly affected the enzymatic activity of antioxidant catalase (CAT), polyphenol oxidase (PPO), and peroxidase (PO) at various stages of growth. Proline was also affected by drought stress and nitrogen. Maximum CAT activity (794.04 OD mg protein min -1 ) was observed at the 4-6 leaf stage under mild drought stress conditions (50% of FC) and a nitrogen application rate 50% less than the recommended level. Increased rates of nitrogen enhanced the PPO activity at the 4-6 and 6-8 leaf stages. PO had a negative response to increased rates of nitrogen application. The highest rate of increase in proline was at the 8-10 leaf stage: 205% and 207% higher under mild drought stress (50% of FC) and severe drought stress (30% of FC) conditions, respectively, compared to favorable moisture conditions (70% of FC). Increased nitrogen application led to an increase in proline production at all stages of sampling (4-6, 6-8, and 8-10 leaf stages).
