“…Regarding the effect of DMPP on yield, our results show that its application did not produce neither a detrimental nor an enhancing effect, supporting the observation of an innocuous effect of DMPP on wheat grain yield, as previous reported by Carrasco and Villar (2001), Weiske et al (2001), Arregui and Quemada (2008) and Polychronaki et al (2012). In this respect, none of the yield components determined in the present study was affected by its application.…”

“…Concerning winter wheat yield, the use of DMPP has shown different responses. While several authors (Carrasco and Villar, 2001;Weiske et al, 2001;Arregui and Quemada, 2008;Polychronaki et al, 2012) did not find significant effects of DMPP application on grain yield in irrigated and rainfed areas, Pasda et al (2001) and Villar and Guillaumes (2010) described a yield increase of 3.1% and 10.2%, respectively. Furthermore, very little research has been conducted regarding the effect of the DMPP on wheat grain quality, which is mainly determined by its protein content.…”

“…N is a key factor in cotton production and high cotton yield can be acquired via the application of optimal fertilizer rates, which can present practical difficulties (Bondada and Oosterhuis, 2001;Ali et al, 2007;Rochester et al, 2009;Polychronaki et al, 2012;Devkota et al, 2013;Klikocka et al, 2016;Li et al, 2017). Insufficient N fertilizer application causes premature senescence, while excessive application causes late ripening and increases environmental pollution.…”

Nitrogen Fertilization Increases Root Growth and Coordinates the Root–Shoot Relationship in Cotton

The root system plays an important role in the growth and development of cotton, and root growth is closely related to shoot growth, both of which are affected by N availability in the soil. However, it is unknown how N affects root growth and the rootshoot relationship under various N rates in the Yellow River Basin, China. Thus, the aim of this study was to assess the impacts of the application rate of N on root growth and the root-shoot relationship, to provide insight into the N regulation of root and shoot growth and N efficiency from the perspective of the root system. A field experiment conducted in 2014 and 2015 was used to determine the effects of N rates (0, 120, 240, and 480 kg ha −1) on root morphology, root distribution, the root-shoot relationship, and cotton yield. A moderate N fertilization rate (240 kg ha −1) increased root length, root surface area, and root biomass in most soil layers and significantly increased total root growth and total root biomass by more than 36.06% compared to the 0 kg ha −1 treatment. In addition, roots in the surface soil layers were more strongly affected by N fertilization than roots distributed in the deeper soil layers. Total root length, total root surface area, and root biomass in the 0-15 cm layer were significantly correlated with shoot biomass and boll biomass. In the 60-75 cm layer, total root length, total root surface area, and root length were significantly positively correlated with seed cotton yield. The application of a moderate level of N markedly increased total shoot biomass, boll biomass, and seed cotton yield. Our results show that increased shoot and boll biomasses were correlated with a significant increase in the root system especially the shallow roots in the moderate N treatment (240 kg ha −1), leading to an increase in cotton seed yield.

“…Nitrogen fertilization has significant impacts on cotton growth, boll development, lint yield, and fiber quality [3][4][5]. In addition, nitrogen can also improve salinity tolerance, water productivity, and nitrogen use efficiency [6][7][8]. However, nitrogen management of cotton is especially difficult because of cotton's indeterminate growth characteristics.…”

Nitrogen Fertilization Effects on Physiology of the Cotton Boll–Leaf System

The objective of this study was to assess the impacts of nitrogen on the physiological characteristics of the source–sink system of upper fruiting branches under various amounts of nitrogen fertilization. A two-year field experiment was conducted with a Bt cotton cultivar in the Yellow River Basin of China. The growth and yield of cotton of the upper fruiting branches were compared under four nitrogen levels: Control (N0, 0 kg ha−1), low nitrogen (N1, 120 kg ha−1), moderate nitrogen (N2, 240 kg ha−1), and high nitrogen (N3, 480 kg ha−1). The results indicated that in the subtending leaves in upper fruiting branches, chlorophyll content, protein content, and peroxidase (POD) activity dramatically increased with nitrogen application, reaching the highest under the moderate nitrogen treatment. The physiological characters in the seeds had the same trends as in the subtending leaves. Furthermore, the moderate nitrogen rate (240 kg ha−1) had a favorable yield and quality. Our results supported that a moderate nitrogen rate (240 kg ha−1) could coordinate the source–sink growth of cotton in the late stage, enhance the yield and fiber quality, and decrease the cost of fertilizer in the Yellow River Basin of China and other similar ecological areas.
