Sodicity in Vertosols used for agricultural production can adversely affect the growth and nutrition of cotton (Gossypium hirsutum L.) plants. Cotton produced in sodic soils has reduced dry matter and lint yield and can develop toxic plant tissue concentrations of sodium (Na) but limited tissue concentrations of phosphorus (P,) potassium (K), and micronutrients. Crops produced on sodic soils frequently suffer from aeration stress after an irrigation or rainfall event, and it was hypothesised that the adverse physical and/or chemical conditions of sodic soils may exacerbate the effects of waterlogging. We measured the impacts of sodicity on the growth, nutrition, and root recovery time of cotton during and after waterlogging in two experiments. In the first, cotton plants were subjected to a 7-day period of inundation in Grey Vertosols with a range of exchangeable sodium percentage (ESP) values from 2 to 25%; 32P was placed in the pots and its accumulation in the plant was used to indicate root activity and recovery after the waterlogging event. In a second experiment, agar was dissolved in nutrient solutions with a range of Na concentrations (9, 30, and 52 mm) matching soil solution Na concentrations in sodic soils, in order to simulate a waterlogging event. Following the waterlogging event, the solutions were labelled with 32P, in order to determine the effect of sodic soil solution chemistry on the rate of recovery of cotton root function after the event. Plant nutrient analysis was used to determine the effects of sodicity and waterlogging on cotton nutrition. In both experiments, waterlogging reduced root activity and reduced the uptake and transport of labelled P by the cotton plants, decreased plant P and K concentrations, and increased the plant Na concentrations. Sodicity exacerbated the effects of waterlogging on root function and cotton nutrition in the soil experiment but not in the nutrient solution experiment, suggesting that any contribution of waterlogging to the patterns of nutrient accumulation in cotton crops produced in sodic fields occurs due to soil physical factors rather than soil solution chemistry.

SummaryIn a greenhouse experiment, the effect of soil sodicity (exchangeable Na percentage 3, 10, 20, 40 and 60) and Zn (0 and 10 mg Zn/kg soil) on soil solution chemistry of Mn was investigated under submerged conditions. Calculated amounts of NaHCO3 were added to Typic Ustifluvent sandy loam soil to obtain required sodicity levels. The soil solutions collected under the atmosphere of N2 gas by gravity were analysed for pH, pE, EC and Mn. Soil submergence decreased pH and pE, and increased Mn concentrations in all the treatments. Maximum Mn concentration was obtained at 14-day submergence. Increasing sodicity levels increased soil solution pH and decreased Mn concentrations. A significant negative correlation (r = -0·74**) was observed between soil solution Mn and pH. Despite large variations in pH, pE, ionic strength and Mn concentration in soil solution, the values of expressions: pH+½log Mn2+ + ½log Pco2 and pMn+2pOH were fairly constant and close to the theoretical values of 4·4 and 17·2 respectively, indicating that the MnCO3-Mn2+ system regulated the solubility of Mn2+ in the sodic soils. Addition of ZnSO4 did not have appreciable effects on the soil solution pH, Mn and solid phases of Mn.

Nesse contexto, o objetivo deste trabalho foi avaliar os impactos da irrigação suplementar do algodoeiro, sem e com adubação química com NPK, e simulando-se as condições de umidade do solo baseada em uma série histórica de dados de precipitação dos últimos 30 anos para a região do Baixo Jaguaribe-CE, considerando-se cenários normais, seca e seca severa. A pesquisa foi desenvolvida no município de Russas – CE, em uma área vizinha à lagoa de estabilização da CAGECE. O ensaio foi instalado em delineamento em blocos ao acaso, com arranjo dos tratamentos em parcelas subsubdivididas, com quatro repetições. Os resultados mostram impactos de cenários hídricos e da suplementação sobre a maioria das variáveis de crescimento das plantas de algodoeiro. A irrigação suplementar com águas residuárias incrementa a produção de biomassa e o vigor das plantas de algodão durante a fase inicial de desenvolvimento, independente da presença ou ausência da adubação com NPK. Esses efeitos foram significativos especialmente nos cenários de seca e seca severa.   Palavras-chave: Gossypium hirsutum L, reuso de água, Irrigação.     ARAUJO, A. F. B.; LACERDA, C.

SUPPLEMENTAL IRRIGATION OF COTTON WITH TREATED WASTEWATER: BIOMETRIC ANALYSIS AND BIOMASS PRODUCTION     2 ABSTRACT   The use of treated wastewater in stabilization ponds for supplementary irrigation emerges as a strategy to increase agricultural production sustainably during the rainy season, eliminating, at least partially, the losses associated with summer. In this context, this work evaluated the impacts of supplementary cotton irrigation, without and with chemical fertilization with NPK, on soil moisture conditions based on a historical series of precipitation data for the last 30 years for the region of Baixo Jaguaribe-CE, considering normal scenarios, drought and severe drought. The research was conducted in the municipality of Russas - CE, in an area adjacent to the CAGECE stabilization pond. The trial was installed in a randomized block design, with the treatments arranged in sub-divided plots, with four replications. The results show impacts of water scenarios and supplementation on most growth variables of cotton plants. Supplementary irrigation with wastewater increases the production of biomass and the vigor of cotton plants during the initial stage of development, regardless of the presence or absence of NPK fertilization. These effects were significant, especially in drought and severe drought scenarios.   Keywords: Gossypium hirsutum L, wastewater, irrigation.

The effects of growth retardants on infestation by Potyphagotarsonemus tatus (broad mite) on cotton (Gossypium hirsutum L. cv. IAC-17) plants was studied. Cotton plants were sprayed with (2-ch1oroethy1) trimethylammonium chloride (CCC) 250, 350 and 450 ppm, and with 1,1-dimethyl-piperidinium chloride (Pix) at concentrations of 84, 167 and 250 ppm. Growth retardants did not give effective control of Potyphagotarsone mus tatus but application of Pix 167 ppm showed a tendency to reduce mite attack.
