“…This eventually results in an imbalance of vegetative and reproductive growth. Besides, the carbon and nitrogen metabolism are affected by excessive nitrogen fertilization, and nitrogen content in boll shells, seeds, and physiological metabolism would rise [35], which would inhibit the photosynthetic products' transportation to the boll. This could cause a decrease in boll weight and fiber quality.…”

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.

“…In a similar pattern, low N-treated plants have poor photosynthesis and photosynthates translocation to the boll, which resulted in lesser number of bolls plant −1 , low boll weight, and hence low yield as compared to moderate and high N levels (Bondada and Oosterhuis, 2001). In addition, the N contents in the shells, seeds, and physiological metabolism will rise (Ferrari et al, 2011), which would inhibit the transportation of photoassimilates to the boll and eventually decrease the boll weight and cotton yield under low N level (Chen et al, 2019). Thus, the increase in boll number and weight under moderate to high N levels in CCRI-69 could be attributed to higher photosynthetic efficiency and more photosynthates translocation, which encourages the development of better reproductive organs and hence yield.…”

Nitrogen (N) plays an important role in various plant physiological processes, but studies on the photosynthetic efficiency and enzymatic activities in the cotton subtending leaves and their contribution to yield are still lacking. This study explored the influence of low, moderate, and high N levels on the growth, photosynthesis, carbon (C) and N metabolizing enzymes, and their contribution to yield in CCRI-69 (N-efficient) and XLZ-30 (N-inefficient). The results showed that moderate to high N levels had significantly improved growth, photosynthesis, and sucrose content of CCRI-69 as compared to XLZ-30. The seed cotton yield and lint yield of CCRI-69 were similar under moderate and high N levels but higher than XLZ-30. Similarly, moderate to high N levels improved the C/N metabolizing enzymatic activities in the subtending leaf of CCRI-69 than XLZ-30. A strong correlation was found between subtending leaf N concentration with C/N metabolizing enzymes, photosynthesis, sucrose contents, boll weight, and seed cotton yield of N-efficient cotton genotype. These findings suggest that subtending leaf N concentration regulates the enzymatic activities and has a key role in improving the yield. These parameters may be considered for breeding N-efficient cotton genotypes, which might help to reduce fertilizer loss and improve crop productivity.

“…Productivity of all crops especially cotton in Pakistan has remained below compared to other cotton growing countries namely, Australia, South Africa, and China. Poor agronomic practices including various inputs like weather, land, genetic resources and water (Deng et al 2004;Maqsood et al 2006;Mahavishnan and Rekha 2007), nitrogen fertilizers (Ferrari et al 2011), choice of the most promising cultivars (Killi et al 2005;Wilde et al 2008), and plant density (Kreig 1998) are of prime importance resources.…”

Response of cotton crop to exogenous application of glycinebetaine under sufficient and scarce water conditions

et al. 2014

Irrigation water is the basic resource to exploit the potential of cotton crop under an arid or a semi-arid environment. Under limited water conditions, various compatible solutes like glycinebetaine are being used to ameliorate the drought stress. Exogenous application of glycinebetaine (GB): GB 1 (100 mg L-1), GB 0 (no application) was done in adequate water (DS 0) and in drought stress condition (DS 1) at arid environment during the growing seasons of years 2009 and 2010. Results demonstrated that application of GB improved the physiological processes of crop leading to better crop performance. Exogenous application of GB increased the drought tolerance with remarkable improvement in photosynthetic process and exhibited higher growth and yield. It was further noted that this technique was economically sustained; predicted higher radiation and water-use-efficiency; and can be applied in limited water condition to avoid yield losses.
