“…) cannot be ignored, which indicates that excessive or insufficient N application rates reduce NUE. Similar results were also observed by Zhang et al () who reported that the NUE at low N rates was higher than that at high N rates, but comparable to that at moderate N rate. In this study, CRU increased NUE by 25–124% and increased lint yield by 7–30% compared to urea treatments.…”

Excessive nitrogen (N) fertilizer input leads to higher N loss via ammonia (NH3) volatilization. Controlled‐release urea (CRU) was expected to reduce emission losses of N. An incubation and a plant growth experiment with Gossypium hirsutum L. were conducted with urea and CRU (a fertilizer mixture of polymer‐coating sulfur‐coated urea and polymer‐coated urea with N ratios of 5 : 5) under six levels of N fertilization rates, which were 0% (0 mg N kg−1 soil), 50% (110 mg N kg−1 soil), 75% (165 mg N kg−1 soil), 100% (220 mg N kg−1 soil), 125% (275 mg N kg−1 soil), and 150% (330 mg N kg−1 soil) of the recommended N fertilizer rate. For each type of N fertilizer, the NH3 volatilization, cotton yield, and N uptake increased with the rate of N application, while N use efficiency reached a threshold and decreased when N application rates of urea and CRU exceeded 238.7 and 209.3 mg N kg−1 soil, respectively. Ammonia volatilization was reduced by 65–105% with CRU in comparison to urea treatments. The N release characteristic of CRU corresponded well to the N requirements of cotton growth. Soil inorganic N contents, leaf SPAD values, and net photosynthetic rates were increased by CRU application, particularly from the full bloom stage to the initial boll‐opening stage. As a result, CRU treatments achieved significantly higher lint yield by 7–30%, and the N use efficiency of CRU treatments was increased by 25–124% relative to that of urea treatments. These results suggest that the application of CRU could be widely used for cotton production with higher N use efficiency and lower NH3 volatilization.

“…O manejo criterioso da água residuária na fertirrigação permite fornecer nutrientes e suprir parcialmente as necessidades hídricas das plantas, o que reduz os problemas ambientais, devido ao menor lançamento de poluentes em cursos hídricos, e a demanda por outras fontes de água de melhor qualidade. Entretanto, apesar dessas vantagens, pode ocorrer a contaminação do solo e de águas subterrâneas, devido à lixiviação no período chuvoso em regiões semiáridas, quando utilizado o critério de irrigação (ERTHAL et al, 2010;SILVA et al, 2011;ZHANG et al, 2012).…”

Além disso, a maioria das comunidades rurais não é atendida com sistemas de tratamento de esgoto, gerando efluentes com potencial uso agrícola. Assim, avaliou-se o crescimento e a produtividade do algodoeiro, fertirrigado com diferentes doses de água residuária sanitária bruta (ARB) e efluente de tratamento terciário (ART), visando o fornecimento de potássio em cobertura, na dose referência de 40 kg ha-1 de K2O. O experimento de campo seguiu o esquema de parcelas subdivididas no tempo, tendo nas parcelas cinco tratamentos (Testemunha: Água limpa e adubação mineral; 100% e 150% da dose referência de potássio em cobertura tanto via ART quanto via ARB) e nas subparcelas quatro épocas de avaliação, no delineamento em blocos casualizados, com quatro repetições. Os tratamentos com ambas as águas residuárias suprem a necessidade de potássio em cobertura da cultura sem prejudicar o diâmetro caulinar, número de folhas, diâmetro de copa e altura, bem como a produtividade da cultura. A água residuária bruta na dose de 150% da adubação potássica em cobertura proporciona maior produtividade no algodoeiro. Palavras-chave: Reúso de esgoto bruto. Reúso de esgoto. Gossypium hirsutum.

R.GROWTH AND YIELD OF COTTON FERTIGATED WITH SANITARY WASTEWATER IN THE SEMI-ARID REGION OF MINAS GERAIS 2 ABSTRACT Most Brazilian municipalities do not have appropriate wastewater treatment systems, with discharge into rivers, degrading quality of surface water. Furthermore, most rural communities do not have sewage treatment systems, generating effluents with potential agricultural use. Thus, we assessed growth and yield of cotton fertigated with different doses of raw sanitary wastewater (ARB) and effluent of tertiary treatment (ART), to supply potassium topdressing according to reference dose of 40 kg K2O ha-1. The field experiment in randomized blocks and split-plot in time design with four replications was used with five treatments (control: Clean water and mineral fertilizer; 100% and 150% of potassium reference dose in topdressing by ARB or ART application) and four evaluation times in subplots. The two wastewater sources meet the potassium topdressing requirements without any effect on stem diameter, leaf number, crown diameter and cotton height, or yield. The highest cotton yield was promoted by 150% of the potassium reference dose in topdressing with raw wastewater. Keywords: Raw sewage reuse. Sewage reuse. Gossypium hirsutum. Potassium topdressing.

“…Dong et al (2012) suggested that N fertilizer can be used at a moderately lower rate and more efficiently than have been traditionally used. Zhang et al (2012) showed that the use of moderate N rate would produce more lint than other N rates; therefore, it may be more cost-effective and desirable to apply not more than 120 kg N ha −1 . Thus, N nutrition, unequivocally, is one of the most pivotal facets of cotton production (Bondada & Oosterhuis 2001).…”

Wheat (Triticum aestivum L.) residues and nitrogen (N) management are the major problems in the southern part of Iran where irrigated wheat-cotton (Gossypium hirsutum L.)-wheat rotation is a common practice. A 2-year (2009-2011) field experiment was conducted as a split plot design with four replications at a cotton field (Darab), Fars Province, Iran, to determine the influence of different rates of wheat residue (0%, 25%, 50%, and 75%) incorporation and N rates (150, 200, 300, and 400 kg ha −1 ) on weed suppression, yield, and yield components of cotton. Results showed that a higher residue incorporation and a lower N rate improved weed suppression in both years. For treatments receiving 150 kg N ha −1 and 75% of wheat residues (2250 kg ha −1 ), weed biomass and density were significantly lower compared to treatments receiving 400 kg N ha −1 . The highest cotton lint yield (about 2400-2700 kg ha −1 ) was obtained by 300 kg N ha −1 in the absence of residue application, in both years. Incorporation of 25% of wheat residue (750 kg ha −1 ) and application of 300 kg N ha −1 are recommended to guarantee an optimum level of cotton lint yield and weed suppression in a wheat-cotton-wheat rotation in this region.
