Objetivou-se, neste trabalho, avaliar a interação entre salinidade e o uso de bioestimulante (Stimulate®) sobre desenvolvimento do feijão caupi. A semeadura foi feita em vasos utilizando-se, como substrato, um Argissolo Vermelho Amarelo. O experimento obedeceu delineamento inteiramente casualizado esquema fatorial 2 x 7. Os tratamentos se constituíram da combinação dois níveis sais água irrigação seis formas aplicação (Ausência, Tratamento sementes, Foliar aos 20 dias após (DAS), 40 DAS,...
Abstract: Rapid tests have been essential to evaluate the physiological potential of seeds and tetrazolium test is one those which used by seed companies. The objective study was establish procedure for in Libidibia ferrea (Mart. Ex Tul.) L.P. Queiroz var. seeds. For this, three solution concentrations (0.05, 0.075 0.1%) staining periods (1, 3 6 hours) at temperatures 35 40 °C were tested. also evaluated germination test, whose result compared with viability test. experimental design...
Objetivou-se com este trabalho avaliar o efeito da salinidade na solução nutritiva sobre a produção de rúcula, cultivada em diferentes substratos. O ensaio foi desenvolvido ambiente protegido do Departamento Ciências Ambientais e Tecnológicas Universidade Federal Rural Semi-Árido Mossoró-RN, instalado delineamento experimental inteiramente casualizado, esquema fatorial 5 x 3, três repetições. Foram utilizados cinco níveis nutritiva, obtidos ou sem uso água residuária piscicultura (S1-0,5;...
The objective of this study was to evaluate the effects a biostimulant on gherkin seeds, cultivar Liso de Calcutá, under conditions salt stress. A split-plot experimental design with five replications used; main plot represented by two levels irrigation water salinity (0.5 and 3.5 dS m-1), subplot composed doses applied as seed treatment (0, 5, 10, 15, 20 mL kg-1). following variables were evaluated: number leaves; branches; length largest branch; leaf, stem, fruit total dry matter; fruits;...
Abstract: The physiological quality of seeds used in agricultural production is one the main factors that should be considered when implanting culture. This study aimed at evaluating bur gherkin seeds, cv. Liso de Calcutá, coming from plants grown were previously treated with biostimulant (0, 5, 10, 15 and 20 mL. kg-1 seeds) cultivated two irrigation water salinities (0.5 3.5 dS. m-1). Initially, content was determined following tests performed: germination, accelerated aging, greenhouse...
Salt stress stands out as one of the main limiting factors in agricultural production arid and semi-arid regions, due to its osmotic ionic effects on plants. In this context, objective was evaluate physiological responses sugar-apple seedlings irrigated with saline wastewater under different doses NPK. The experiment carried a greenhouse, randomized block design, 3 x 5 factorial scheme, four replicates. Three irrigation waters were tested: local-supply water (control), reject brine fish...
O uso de água salina na produção hortaliças é um dos principais desafios pesquisadores e produtores rurais. cultivo em substrato inerte pode ser uma alternativa, vez que o reduzido potencial matricial reduzir efeito da salinidade sobre as plantas. trabalho foi desenvolvido ambiente protegido no Departamento Ciências Ambientais Tecnológicas Universidade Federal Rural do Semi-Árido, Mossoró-RN, objetivou-se avaliar desempenho duas cultivares rúcula cultivadas fertirrigadas com soluções...
Este trabalho foi desenvolvido com o objetivo de avaliar desempenho duas cultivares rúcula irrigadas águas salinas. Utilizou-se delineamento em blocos inteiramente casualizados, os tratamentos arranjados no esquema fatorial 2 x 5, quatro repetições. Os foram compostos pelas combinações (C1-Folha Larga e C2-Cultivada), níveis salinidade (S1=0,5; S2=2,0; S3=3,5 S4=5,0 dS m-1). O cultivo realizado recipientes plásticos capacidade para 10 litros, tendo como substrato Latossolo vermelho-amarelo...
1024x768 Objetivou-se com este trabalho identificar o perfil dos consumidores de hortalicas do municipio Apodi- RN, quanto as preferencias, principal local aquisicao, comportamento no momento das compras, dentre outros aspectos. Foram realizadas entrevistas 100 hortalicas, sendo que 50% foram durante suas compras na feira-livre e os feitas em residencias escolhidas aleatoriamente. Dentre entrevistados pode-se perceber a maioria era sexo feminino, entre 20 40 anos, casado, provenientes da...
ABSTRACT The objective of this study was to evaluate the use saline water grow cucumbers cultivated in substrate composed coconut fiber and washed fine sand (1:1) submitted split-root system. experimental design completely randomized, with eight treatments four replicates. Treatments consisted different fertigation managements, comprising two nutrient solutions electrical conductivities (1.65 6.25 dS m-1), applied a continuous or alternated way, splitting not root system (S/S). Growth yield...
ABSTRACT This study aimed to establish an adequate tetrazolium test procedure estimate okra seed viability. Initially, seeds from four lots were immersed in alcohol (98%) for 60 minutes, followed by 18-h soak distilled water at 25 °C. Then, the longitudinally sectioned, 0.025, 0.050 and 0.075% solutions 60, 90 120 minutes maintained oven 35 40 Subsequently, evaluated viability, based on tissue color (bright red, pink or dark Carmine red). Simultaneously, a germination was conducted, its...
A Leucaena leucocephala), originária da América Central, produz grandes quantidades de sementes viáveis, o que permite sua propagação em larga escala, e possui crescimento rápido, podendo chegar a 7 metros altura. O uso fertirrigação favorece absorção nutrientes maior das mudas leucena, devido à aplicação solução nutritiva menos concentrada e, consequentemente, com menor condutividade elétrica. Nesse sentido, objetivou-se este trabalho avaliar viabilidade por capilaridade utilizando...
Soursop (Annona muricata L.) is a tropical fruit grown in the semi-arid region of Brazil, where problems quantitative and qualitative scarcity water for irrigation are frequent. Using alternative sources, such as fish farming effluents, can increase availability; however, it presents risks due to its high salinity levels. We aimed evaluate effect with saline effluent NPK doses on soursop seedlings’ ecophysiology. conducted greenhouse experiment using randomized complete block design 2 × 5...
ABSTRACT Custard apple (Annona squamosa L.) is a sensitive fruit crop to salinity. One of the alternatives minimize deleterious effects salt stress adopting mineral fertilization management practices, promoting increased tolerance salts. Therefore, objective present study was evaluate NPK doses mitigate in custard seedlings irrigated with saline wastewater. The experiment performed greenhouse, randomized block design 3 × 5 factorial scheme, corresponding three irrigation waters (local-supply...
