The application of machine learning techniques to determine bioparameters, such as the leaf area index (LAI) and chlorophyll content, has shown significant potential, particularly with use unmanned aerial vehicles (UAVs). This study evaluated RGB images obtained from UAVs estimate bioparameters in sesame crops, utilizing data selection methods. experiment was conducted at Federal Rural University Pernambuco involved using a portable AccuPAR ceptometer measure LAI spectrophotometry...
Underground water reserves in the semi-arid region of Brazil are stored crystal formations that large part have high concentrations salt. However, scarcity this resource makes use necessary for various activities, including agriculture. The aim study was to evaluate brackish on electrical conductivity and pH nutrient solution, production, consumption uptake nutrients Chinese cabbage (Brassica pekinensis L.) under a hydroponic system. experimental design completely randomised, with four...
ABSTRACT The tolerance of crops to salinity is greater in hydroponic systems due the low contribution matric potential total water. objective this study was evaluate use brackish water, prepare nutrient solution and replace evapotranspired volume, rates application on water stress index, potential, leaf succulence consumption cauliflower cv. ‘Piracicaba Precoce’. experimental design completely randomized a 6 x 2 factorial scheme, with six levels used solutions (0.2, 1.5, 2.5, 3.5, 4.5 5.5 dS...
ABSTRACT Water availability in the Brazilian semiarid is restricted and often only water source available has high salt concentrations. Hydroponics allows using these waters for production of various crops, including vegetables, however, salinity can cause nutritional disorders. Thus, two experiments were conducted a greenhouse at Department Agricultural Engineering Federal Rural University Pernambuco, to evaluate effects on mineral nutrition crisphead lettuce, cultivar Taina, hydroponic...
ABSTRACT The underground water reserves in the semi-arid region present high salinity levels. However, scarcity of resource compels use this for several human activities, including agriculture. aim work was to evaluate brackish watercress cultivation (Nasturtium officinale) a hydroponic NFT system (laminar flow nutrients) and effects on consumption, growth, yield nutrient extraction by plant. We studied six levels (0.2; 1.2; 2.2; 3.2; 4.2 5.2 dS m-1), completely randomized experimental...
ABSTRACT The objective was to evaluate the growth and yield of sugarcane irrigated with brackish water leaching fractions. A completely randomized experimental design used, in a 5 x 2 factorial scheme, four replicates. treatments consisted five irrigation salinity levels (0.5, 2.0, 3.5, 5.0 6.5 dS m-1) two fractions (0 0.17), corresponding 100 120% crop evapotranspiration. management performed daily. Irrigation were obtained by adding NaCl CaCl2 public-supply water, order obtain molar ratio...
ABSTRACT Groundwater with high salt concentrations is common in the semiarid region of Brazil. It often makes them inappropriate to conventional agricultural production vegetables. Therefore, objective this work was evaluate watercress and Chinese cabbage crops under a nutrient film technique (NFT) hydroponic system using brackish groundwater. The experiment carried out Poço do Boi region, Ibimirim, Pernambuco, Brazil (8º32'15"S, 37º41'30"W, altitude 431 m). treatments used were: public...
ABSTRACT In Pernambuco, state in the northeastern region of Brazil, coastal areas, due to intrusion seawater, waters used for sugarcane irrigation can have high salt contents and cause serious problems soil plant. The present study aimed evaluate effects with saline water on physiology sugarcane, variety RB867515, irrigated under five salinity levels 0.5; 2.0; 3.5; 5.0 6.5 dS m-1 a completely randomized design, four replicates drainage lysimeters. was conducted period from December 2014 June...
ABSTRACT The objective of this study was to evaluate the contents macronutrients and also chlorine sodium in diagnostic leaf, extraction export sugarcane irrigated with saline water leaching fractions. experiment conducted a complete randomized design 5 x 2 factorial scheme four replications, corresponding five levels salinity (0.5, 2.0, 3.5, 5.0 6.5 dS m-1) two fractions (L1 = 0 L2 0.17). treatments were applied 60 days after planting. At 280 planting, leaves collected used nutritional...
ABSTRACT The objective of this study was to evaluate the concentration cations in leachate soil cultivated with sugarcane irrigated brackish water. An experiment carried out drainage lysimeters at Federal Rural University Pernambuco, Recife campus. experimental design completely randomized a 5 x 2 factorial scheme, four replicates, corresponding five levels electrical conductivity irrigation water (ECw) (0.5, 2.0, 3.5, 5.0 and 6.5 dS m-1) two leaching fractions (LF1 = 0 LF2 0.17) depths...
ABSTRACT This study aimed to evaluate production components of sunflower (Helianthus annuus L.) plants irrigated with domestic wastewaters treated by different processes, two irrigation depths. The experiment was carried out in Ibimirim, state Pernambuco, Brazil, using a randomized block design 4×2 factorial arrangement, four replications. treatments consisted water types (domestic wastewater UASB reactor - DW1; digestion decanter and anaerobic filtration DW2; DW3; public PW4) depths (equal...
Objetivou-se com esse trabalho avaliar a influência da aplicação de diferentes doses biofertilizante via fertirrigação, sobre as trocas gasosas do inhame. O delineamento experimental utilizado foi em blocos casualizados, 5 tratamentos e três repetições. Os foram compostos por cinco (D1 = 0 ml planta-1; D2 30 D3 60 D4 90 D5 120 planta-1). Para verificar dos nas das plantas, analisadas aos 180 dias após o plantio analisador gás infravermelho (IRGA LI-6200), condutância estomática (gs),...
A cana-de-açúcar quando chega à indústria, passa por uma análise tecnológica de rotina para caracterizar sua qualidade. Sabendo que a salinidade pode afetar as culturas diversas maneiras objetivou com o presente trabalho avaliar efeito da água irrigação e duas frações lixiviação nos parâmetros tecnológicos cana-de-açúcar. Realizou-se um experimento em lisímetros drenagem na UFRPE, campus Recife, delineamento inteiramente casualizado esquema fatorial 5x2 4 repetições, sendo cinco níveis...
ABSTRACT Technologies that improve water use efficiency (WUE) and increase crop yields are essential for the development of a responsible productive agriculture. Therefore, objective this study was to evaluate economical planting beds with mulching application different irrigation depths as water-saving technology, determine depth promote optimal plant fruit yield quality two cherry tomato cultivars. The experiment conducted at Federal Rural University Pernambuco, Serra Talhada, PE, Brazil....
