“…Drip fertigation is an alternative, which improves water and nutrient use efficiency and crop production and minimizes the adverse effect of groundwater quality (Ajdary et al, 2007). It was proven that fertigation strategy is one of the factors that has significant effect on nitrogen use efficiency (Hou et al, 2007) and nitrate leaching (Cote et al, 2003;Li et al, 2004;Gardenas et al, 2005;Hanson et al, 2006). This study shows that fertigation strategy has significant effects on seed cotton yield and nitrogen fertilizer use efficiency.…”

“…The intensity of green color in plant leaves directly exhibits the N status of the plant as it is an important component of chlorophyll and responsible for the vegetative growth (Wiedenfeld et al 2009). N is required in larger amounts than other nutrients for cotton production systems (Hou et al 2007). Enhancing agricultural Fig.…”

This review outlines nitrogen (N) responses in crop production and potential management decisions to ameliorate abiotic stresses for better crop production. N is a primary constituent of the nucleotides and proteins that are essential for life. Production and application of N fertilizers consume huge amounts of energy, and excess is detrimental to the environment. Therefore, increasing plant N use efficiency (NUE) is important for the development of sustainable agriculture. NUE has a key role in crop yield and can be enhanced by controlling loss of fertilizers by application of humic acid and natural polymers (hydrogels), having high water-holding capacity which can improve plant performance under field conditions. Abiotic stresses such as waterlogging, drought, heat, and salinity are the major limitations for successful crop production. Therefore, integrated management approaches such as addition of aminoethoxyvinylglycine (AVG), the film antitranspirant (di-1-p-menthene and pinolene) nutrients, hydrogels, and phytohormones may provide novel approaches to improve plant tolerance against abiotic stress-induced damage. Moreover, for plant breeders and molecular biologists, it is a challenge to develop cotton cultivars that can tolerate plant abiotic stresses while having high potential NUE for the future.

“…The cultivation of cotton with its high N requirements (50-412 kg N ha −1 ) and the need for irrigation water (177-463 mm yr −1 , Aneja et al 1996;Navarro et al 1997;Hou et al 2007;Mahmood et al 2008;Janat 2008;Scheer et al 2008a, b;Zhang et al 2008) creates potentially favorable conditions for especially denitrifying microbial activity in the agricultural soil that can result in high emissions of N 2 O and NO. Indeed, significant emissions of these N gases have been observed from cotton fields across the globe (Aneja et al 1996;Mahmood et al 2008;Scheer et al 2008a, b) and the N recoveries from the crop are usually low (e.g.…”

“…Indeed, significant emissions of these N gases have been observed from cotton fields across the globe (Aneja et al 1996;Mahmood et al 2008;Scheer et al 2008a, b) and the N recoveries from the crop are usually low (e.g. less than 60% of the fertilizer-N, Freney et al 1993;Hou et al 2007;Norton and Silvertooth 2007). In China, 5.9 million ha of cropland is cultivated with cotton, corresponding to approximately 4% of the total sowing area, and the ongoing economic development has resulted in a sharp rise of inorganic N fertilizer consumption between 1980 and 2007 (from 9.3 to 23.0 million tons N, China Statistical Yearbook 2008).…”

Nitrous oxide and nitric oxide emissions from an irrigated cotton field in Northern China

Cotton is one of the major crops worldwide and delivers fibers to textile industries across the globe. Its cultivation requires high nitrogen (N) input and additionally irrigation, and the combination of both has the potential to trigger high emissions of nitrous oxide (N 2 O) and nitric oxide (NO), thereby contributing to rising levels of greenhouse gases in the atmosphere. Using an automated static chamber measuring system, we monitored in high temporal resolution N 2 O and NO fluxes in an irrigated cotton field in Northern China, between January 1st and December 31st 2008. Mean daily fluxes varied between 5.8 to 373.0 µg N 2 O-N m −2 h −1 and −3.7 to 135.7 µg NO-N m −2 h −1 , corresponding to an annual emission of 2.6 and 0.8 kg N ha −1 yr −1 for N 2 O and NO, respectively. The highest emissions of both gases were observed directly after the N fertilization and lasted approximately 1 month. During this time period, the emission was 0.85 and 0.22 kg N ha −1 for N 2 O and NO, respectively, and was responsible for 32.3% and 29.0% of the annual total N 2 O and NO loss. Soil temperature, moisture and mineral N content significantly affected the emissions of both gases (p<0.01). Direct emission factors were estimated to be 0.95% (N 2 O) and 0.24% (NO). We also analyzed the effects of sampling time and frequency on the estimations of annual cumulative N 2 O and NO emissions and found that low frequency measurements produced annual estimates which differed widely from those that were based on continuous measurements.
