Com base em um novo princípio de se igualar as diferenças de pressão nas laterais de cada lado, a equação final do método apresentada num formato padrão e adimensional também facilitou o processamento de outros métodos já consagrados na literatura, bastando substituir a constante que caracteriza cada método. Um teste comparativo foi realizado com outros dois modelos com princípios de que se igualem as pressões mínimas ou pressões médias das laterais pareadas. A aplicação em um exemplo de projeto cobrindo várias condições indicaram resultados mais precisos para as linhas laterais pareadas, com menor diferença de desempenho entre os trechos em aclive e declive.

METHOD FOR DESIGNING PAIRED MICROIRRIGATION LATERALS WITH VARIABLE COMMERCIAL DIAMETERS 2 ABSTRACT This study aims to evaluate a more comprehensive, simple, and highly accurate method for designing paired microirrigation sides with constant or mixed diameters on uniformly sloped terrains. On the basis of a new principle of equalizing pressure differences between the sides on each side, the final equation of the method, which is presented in a standard and dimensionless format, also facilitates the processing of other well-established methods in the literature by simply replacing the constant that characterizes each comparative method. tests were performed with two other models based on the principles of equalizing either the minimum or average pressures of the paired sides. Application to a design example covering various conditions indicated more accurate results for paired sides, with reduced performance differences between upslope and downslope segments. Keywords: Pressure rate, distribution uniformity, energy gradient line.

    Sesame irrigation is essential in drought‐prone regions. However, information about the water needs of sesame is scarce. Therefore, the objective of this study was to determine crop evapotranspiration (ETc) and the sesame crop coefficient (Kc) during the rainy (S1) and dry (S2) seasons in the coastal tablelands of Alagoas, Brazil. The BRS Seda cultivar was grown in Rio Largo, Alagoas, Brazil, between 2021 and 2022. A system with 25 drainage lysimeters was installed to estimate the daily and cumulative ETc and the Kc for the entire crop cycle. The ETc was partitioned into transpiration (T) and evaporation (E), and the basal crop coefficients (Kcb) and soil evaporation coefficients (Ke) were subsequently estimated. The daily and cumulative ETc were 3.04 mm day−1 and 450.4 mm cycle−1, respectively, in S1 and 3.52 mm day−1 and 440.1 mm cycle−1, respectively, in S2. Regardless of the season, T was the main water flux (74%–80% of the ETc). The mean values of Kc were similar for S1 (0.79) and S2 (0.75), and Kcb and Ke followed the same trend as T and E, respectively. The accumulated ETc and Kc of sesame cultivated in the coastal tablelands of Alagoas, Northeast Brazil, are similar for the rainy and dry seasons.

    Revista Brasileira De Engenharia Agricola E Ambiental, 2025
    The water status of crops is directly affected by soil water availability. As such, this study aimed to analyze water relations in maize (double-cross hybrid AG 1051) under different soil moisture contents (80, 90, 100, 110, and 120% of field capacity - FC) and fertilization systems (conventional and fertigation). The experiment was carried out in a greenhouse at the Agricultural Engineering Department of Universidade Federal Rural de Pernambuco, in the municipality of Recife, Pernambuco state, Brazil, from August to October 2019. The experimental design was randomized blocks with a 5 × 2 factorial scheme, four replicates and a total of forty experimental units. At soil moisture levels below 100% of field capacity (100% FC), fertigation increased the relative water content, leaf succulence, leaf water potential, and osmotic adjustment of maize plants. When compared to conventional fertilization, fertigation resulted in higher transpiration rates and better water use efficiency in crops irrigated at 95% of field capacity (95% FC). In plants submitted to soil moisture levels below 100% FC, the fertilization system influenced water, osmotic, and pressure potential, and osmotic adjustment occurred.
  • Validation of Double Constant and Falling Head Permeameter for Determination of Hydraulic Conductivity of Soils in the Laboratory

    Revista Brasileira De Geografia Fisica, 2024
    The objective of this research was to validate alternative equipment for determining the hydraulic conductivity of saturated soil (Ksat) in laboratory settings. The aim was to develop a single piece of equipment that could be used to carry out tests using both the constant-head permeameter (CHP) and the falling-head permeameter (FHP) methods with minimal disturbance to the samples. To this end, undisturbed soil samples were collected (in volumetric cylinders with 100 and 250 cm3) from three soil profiles with different textures to evaluate the sensitivity of the double permeameter (DP) in determining Ksat, considering the method, the sample size, and the textural class of the soils. To assess the efficacy of the DP in estimating Ksat, the coefficient of variation (CV) was determined for the two methods (CHP and FHP), the sample size (100 and 250 cm3), and the applied hydraulic head (cwc) (constant: 1.5 and 2.5 cwc; falling: Δhi, upper limit, h1 = 67.6 and h2 = 57.6 cwc; Δhii, medium limit, h1 = 49.3 and h2 = 39.3 cwc; and Δhiii, lower limit, h1 = 31.3 and h2 = 21.3 cwc). The results indicate that the DP may be employed as an alternative permeameter for Ksat tests employing the CHP and FHP methods. The most favorable statistical coefficients were observed in tests conducted with samples of a sandy texture (Profile 3, Ap horizon), particularly those with a larger volume (250 cm3), for both the CHP and FHP methods, irrespective of the applied hydraulic head. The equipment can be utilized within the full range of methodological limits employed in this study, and the appropriate limit must be selected according to the physical properties of the soil to be employed in the tests.

These phases can be directly affected by soil management and cultivation, where mechanized raw sugarcane harvesting can improve them. Thus, this research aimed to evaluate soil porosity (P) and its pore size distribution (PSD) in classes, as well as the soil water content at field capacity (qfc), cultivated with sugarcane under two harvest methods: raw and burnt sugarcane. Thus, three areas were compared: two under different ways of harvesting sugarcane (with and without burning); and one in a native forest as a reference. P, PSD (macro, meso, and microporosity), and qfc were determined in soil samples collected in volumetric cylinders, by the saturation and tension table methods, respectively. The results point out that the soil under native forest presented the highest values for the evaluated attributes, indicating that sugarcane cultivation, with or without burning, reduces them. Burning promoted negative changes in the soil concerning water conduction and soil aeration, even in a recent cultivation area (five years), promoted by the reduction of qfc (-62.09%), mainly reflecting the decrease in macroporosity (-31.73%) and microporosity (-24.48%).

RETENÇÃO DE ÁGUA E DISTRIBUIÇÃO DE TAMANHO DE POROS EM SOLOS CULTIVADOS COM CANA-DE-AÇÚCAR EM COMPARAÇÃO COM ÁREA DE PRESERVAÇÃO PERMANENTE 2 RESUMO A condição estrutural do solo, cultivado com cana-de-açúcar, está relacionada com o tipo de colheita adotado, o qual influencia a porosidade do solo, uma importante variável de circulação das fases líquida e gasosa do solo. Estas fases podem ser afetadas diretamente pelo manejo e cultivo do solo, onde a colheita mecanizada da cana-de-açúcar crua pode melhorá-las. Assim, esta pesquisa objetivou avaliar a porosidade do solo (P) e sua distribuição de tamanho de poros (PSD), bem como o conteúdo de água na capacidade de campo (qfc) do solo cultivado com cana-de-açúcar sob dois métodos de colheita: crua e queimada. Desse modo, foram comparadas três áreas: duas sob diferentes formas de colheita de cana (com e sem queima); e uma em mata nativa, como referência. A P, PSD (macro, meso e microporosidade) e qfc foram determinadas nas amostras coletadas em cilindros volumétricos, utilizando-se os métodos da saturação e da mesa de tensão, respectivamente. Os resultados comprovam que o solo sob mata nativa apresentou os maiores valores para os atributos avaliados, comprovando que o cultivo da cana-de-açúcar, com ou sem queima, reduz os valores desses atributos. A queima promoveu mudanças negativas no solo em relação à condução hídrica e aeração do solo, mesmo em área de cultivo recente (cinco anos), promovidas pela redução da qfc (-62,09%), refletindo, principalmente na diminuição da macroporosidade (-31,73%) e microporosidade (-24,48%).

Os tratamentos consistiram em quatro lâminas de irrigação (0, 50, 100 e 150% da ETC) e 5 doses de N (0, 40, 80, 120 e 160 kg ha-1). Foi utilizado um delineamento de 5x4x2 com 3 repetições em blocos inteiramente casualizados. A produtividade foi obtida por meio da pesagem dos colmos. A partir da função de produção foram determinadas a região de produção máxima, a taxa marginal de substituição e a região de produção racional. Através da produtividade foram calculados os rendimentos de açúcar e álcool. As lâminas, doses de N e produtividades máximas encontradas foram, de 2033 mm, 131 Mg ha-1 e 125 Mg ha-1 no solo sem subsolagem e de 1729 mm, 137 Mg ha-1 e 127 Mg ha-1 no solo com subsolagem.

FUNCTION OF PRODUCTION AND YIELD IN SUGAR CANE CULTIVATED UNDER DIFFERENT MANAGEMENT NUTRITIONAL AND WATER AND SUBSOLATION 2 ABSTRACT With the objective of identifying the production function that estimates the maximum yield of sugar and alcohol in sugarcane cultivated with different doses of nitrogen, irrigation depths in soil with and without subsoiling, an experiment was carried out in the field with ratoon cane. Treatments consisted of four irrigation depths (0, 50, 100 and 150% of ETC) and 5 N doses (0, 40, 80, 120 and 160 kg ha-1). A 5x4x2 design with 3 replications in completely randomized blocks was used. Productivity was obtained by weighing the stalks. From the production function, the region of maximum production, the marginal rate of substitution and the region of rational production were determined. Through productivity, the yields of sugar and alcohol were calculated. The depths, N doses and maximum productivity found were 2033 mm, 131 Mg ha-1 and 125 Mg ha-1 in the soil without subsoiling and 1729 mm, 137 Mg ha-1 and 127 Mg ha-1 in the soil with subsoiling. For the highest yield of sugar and alcohol, the application of inputs should remain at doses of N between 80 and 160 kg ha-1 and depths between 1456 and 1731 mm. Keywords: yield function, isoproduct curve, Saccharum officinarum, marginal rate, alcohol.

    Different soil management systems can change the sugarcane yield and quality parameters for sugar/ethanol production. The objective of this study was to evaluate the effects of subsoiling on the inter-row of sugarcane ratoons after the second harvest on productivity and technological quality. Productivity was estimated in tonnes of sugarcane per hectare (TSH), and technological quality parameters were apparent sucrose percentage (Pol) and total sugar recoverable per hectare (TRS). The apparent sucrose percentage and total recoverable sugar were measured in tonnes per hectare, corresponding to the parameters TSH and total recoverable sugar in tonnes per hectare (TTRSH), respectively. This research was carried out at the Experimental Sugarcane Station at the Federal Rural University of Pernambuco in the northeast region of Brazil. A randomized complete block design was used, with two treatments: conventional tillage and inter-row subsoiling. Subsoiling provided a significant gain of stalk yield of 5.53 tonnes per hectare. The other parameters evaluated did not differ significantly.
