“…Bezerra et al (2008) also verified an increase in the seed cotton's yield with the increase of irrigation depth, being the highest one found with the depth of 120% ETc. Rajak et al (2006) found an increase of 33% in the yield when a 120% ETc irrigation depth was used -compared with 80% ETc irrigation -, results that are similar to those obtained by this research.…”

A B S T R A C TThe objective of this study was to evaluate the effect of irrigation depths on seed cotton yield and water-use efficiency of cotton cultivars in the Brazilian semi-arid region. Field experiment was conducted during two consecutive years in the Apodi region, RN, using sprinkler irrigation. The experiment consisted of factorial combination in split-plots, composed of four irrigation depths (130; 100; 70 and 40% ETc and four cotton cultivars -FiberMax 993, BRS 286, BRS 336 and BRS 335), in randomized block design with 4 replicates. Data were evaluated by mean test (Tukey) and regression analysis. Considering the irrigation depths of 40% ETc, cotton yield was 48% lower compared to the higher irrigation depth (130% ETc). The higher water-use efficiency (0.69 kg m -3 ) was obtained with 70% ETc irrigation depth. The highest seed cotton yield was achieved with the higher water depth for all evaluated cultivars. Yield response factor (Ky) was equal to 0.632, 0.711, 0.784 and 0.858, for FiberMax 993, BRS 286, BRS 335 and BRS 336 cultivars, respectively. FiberMax 993 and BRS 286 cultivars presented the best performance, showing that they are more suitable for irrigated farming in the semi-arid region.Produtividade de cultivares de algodoeiro herbáceo sob diferentes lâminas de irrigação no semiárido brasileiro R E S U M O O objetivo deste trabalho foi avaliar o efeito de lâminas de irrigação sobre o rendimento e eficiência no uso da água de cultivares de algodoeiro no semiárido brasileiro. Foi conduzido um experimento de campo por dois anos consecutivos, na região de Apodi, RN, com irrigação por aspersão. O experimento consistiu de uma combinação fatorial em parcelas subdivididas, sendo quatro lâminas de irrigação (130; 100; 70 e 40%ETc) e quatro cultivares de algodoeiro (FiberMax 993, BRS 286, BRS 336 e BRS 335), em delineamento de blocos casualizados, com quatro repetições. Os dados foram avaliados através de teste de médias (Tukey) e análise de regressão. A produtividade com a menor lâmina aplicada (40% ETc) foi 48% menor se comparada a maior lâmina (130% ETc). A maior eficiência no uso da água foi encontrada com a lâmina de 70% ETc (0,69 kg m -3 ) e a maior produtividade de algodão em caroço foi alcançada com a lâmina de irrigação igual a 130%ETc para todas as cultivares avaliadas. O fator de resposta do rendimento (Ky) foi igual a 0,632; 0,711; 0,784 e 0,858 para as cultivares FiberMarx 993, BRS 286, BRS 335 e BRS 336, respectivamente. As cultivares FiberMax 993 e BRS 286, no geral, apresentaram os melhores resultados, demonstrando serem mais indicadas para o cultivo irrigado na região semiárida.

“…In all of the cropping systems, the estimated EC values were less than 3 dS m −1 , but were significantly different between the crop types. The salt amounts were the highest in the planted cotton fields, consistent with other studies that indicated higher salt accumulation due to the effect of tillage and irrigation in the annual cropping systems [38]. This is especially noticeable with the increase in the use of the local saline well ground water for irrigation in southwestern New Mexico [39].…”

Abstract:Improving the soil quality in arid agro-ecosystems requires a greater understanding of how the time-of-sampling and management affect the soil measurements. We evaluated the selected soil quality indicators on samples collected at a 0-0.15 m depth, and at various sampling dates of the year, corresponding to the fall of 2015, winter of 2015/2016, spring of 2016, and the summer of 2016. The three crop management systems sampled included alfalfa (Medicago sativa), upland cotton (Gossypium hirsutum), and pecan (Carya illinoinensis). The soil properties measured included the wet aggregate stability (WAS), mean weight diameter of dry aggregates (MWD), dry aggregates greater than 2 mm (AGG >2 mm), dry aggregates less than 0.25 mm (AGG <0.25 mm), available water capacity (AWC), soil organic matter (SOM), permanganate oxidizable carbon (POXC), soil bulk density (BD), soil electrical conductivity (EC), pH, nitrate-nitrogen (NO3-N), extractable potassium (K), extractable phosphorus (P), calcium (Ca), magnesium (Mg), sodium adsorption ratio (SAR), and micronutrients (zinc, iron, copper, and manganese). Out of the 21 soil measurements, 15 varied significantly with the time-of-sampling within a year, although there were no consistent trends in variability. However, only a few measurements differed significantly with the crop management practices tested. Wet aggregate stability, MWD, AWC, and BD were significantly higher in the summer, while POXC and SOM were significantly higher in the fall and winter, respectively. Soil quality indicators such as NO3-N, K, and P decreased significantly during the spring. This study shows that the seasonal variability of the soil measurements can be significant in the arid agro-ecosystems, with the magnitude of variation depending on the measurement type. The soil managers in the region need to account for this variability, in order to be able to assess the changes in the soil quality. Also, because of the variability that can occur across the different sampling dates within a year, it is advisable to sample during the same period every year, for a consistent interpretation of the directional changes of the soil quality indicators.

“…Limitações para expansão de áreas produtoras de cana-de-açúcar têm levado à necessidade de pesquisas que contemplem o aumento de produtividade e, principalmente, a otimização do uso da água, seja pela aplicação de volumes mais adequados (IGBADUN et al, 2006), seja pela utilização de sistemas de irrigação mais eficientes (RAJAK et al, 2006) e aprimoramento do manejo de irrigação (JALOTA et al, 2006). Sob condições de cultivo em sequeiro, estudos sobre o consumo de água da cana-de-açúcar tornam-se importantes em razão de existir uma variação genotípica de resposta ao estresse hídrico por diferentes variedades (SMIT & SINGELS, 2006;TEJERA et al, 2007).…”

RESUMO:Medições do fluxo de seiva são importantes não somente no campo da agrometeorologia, mas também em estudos de natureza fisiológica para identificação de doenças vasculares e pesquisas destinadas à quantificação do movimento de água no sistema solo-planta--atmosfera. Este trabalho foi realizado com o objetivo de avaliar o desempenho do método do balanço de energia, a partir da inserção de um minirresistor no centro do colmo de plantas de cana--de-açúcar, visando à determinação do fluxo de seiva sob condições ambientais distintas, utilizando--se de medições gravimétricas como padrão comparativo. O experimento foi conduzido em uma casa de vegetação não climatizada, localizada na área experimental da Universidade Federal de Viçosa, Viçosa -MG. Com base no erro médio de estimativa (MBE), verificou-se que o método do balanço de energia apresentou desempenho satisfatório para a determinação da transpiração da cana-de-açúcar, tanto em condições de céu nublado como parcialmente nublado, tendo subestimado os valores gravimétricos em apenas 3,0 e 6,5 g planta -1 h -1 , respectivamente. Em termos percentuais, esses valores correspondem a 4 e 5% da transpiração máxima da cana-de-açúcar. PALAVRAS-CHAVE:transpiração, Saccharum officinarum, eficiência do uso de água, disponibilidade hídrica, irrigação. SUGARCANE SAP FLOW DETERMINATION BY THE ENERGY BALANCE METHODABSTRACT: Sap flow measurements are important not only in the agrometeorology field, but also in studies of physiological nature to identify vascular diseases and researches concerned with quantification of water movement in soil-plant-atmosphere system. This study was carried out to evaluate the performance of the energy balance method, implemented by insertion of a miniresistor in the stem center of sugarcane plants, in order to determine the sap flow under distinct environment conditions, utilizing gravimetric measurements as comparative standard. The experiment was conducted in a non-environment controlled greenhouse, located at the Federal University of Viçosa, Viçosa-MG. Based on the mean bias error (MBE), it was verified that the energy balance method presented satisfactory results to determine sugarcane transpiration, both in cloudy and partly cloudy sky conditions, underestimating gravimetric values by only 3.0 and 6.5 g plant -1 h -1 , respectively. In percentage terms, these values correspond to 4 and 5% of the maximum sugarcane transpiration.
