The increase in water demand regions with limited good-quality resources makes it necessary to study the effect of low-quality on plant metabolism. Therefore, objective this was evaluate and salt stress levels mineral elements accumulation toxic Na+ Cl− leaves their consequences production variables sorghum cultivar IPA SF-15. design adopted randomized blocks a factorial scheme (4 × 4), four concentrations (1.5; 3.0; 4.5, 6.0 dS m−1) irrigation depths (51.3; 70.6; 90.0, 118.4% crop...
Agriculture in semiarid regions commonly face problems because of salt and availability irrigation water. Considering this, studies on cultures resistant to water stresses involving sweet sorghum are required. Therefore, the aim was evaluate growth other mechanisms tolerance salinity deficit BRS 506 sorghum. The experimental design conducted Upanema-RN, Brazil, randomized blocks, where isolated interactive effect 3 levels, expressed as electrical conductivity (1.5, 3.8, 6.0 dS m−1), depths...
Abstract Salinity reduces feijão-caupi production, and the search for tolerant varieties becomes important within agricultural context, as, in addition to being used field, they can be genetic improvement. The objective was a identify variety that is salinity considering physiological quality of seeds seedling growth. A 2 × 4 factorial scheme used, referring Pingo-de-ouro Coruja, four electrical conductivities water (0; 3.3; 6.6 9.9 dS m-1). growth seedlings were analyzed, cumulative...
Sweet sorghum (Sorghum bicolor [L.] Moench) is a plant that can be an alternative for the production of bioethanol in semi-arid regions. The objective this work was to evaluate sweet 'BRS 506' under salt and water stress. experimental design randomized blocks, factorial scheme (4x4), with first factor referring electrical conductivities irrigation (1.5; 3.0; 4.5; 6.0 dS m-1) second refers depths (53, 67, 85 95% crop evapotranspiration). Gas exchange, leaf status, sugars growth were...
The production of yellow passion fruit seedlings is common among producers. Low cost techniques to maximize and reduce the with application cattle manure make feasible. objective experiment was evaluate different concentrations in substrate without liquid biofertilizer seedlings. carried out at Universidade Estadual da Paraíba, Catolé do Rocha county, Paraíba state. experimental design completely randomized, a 5 × 2 factorial scheme, repetitions end 3 plants per plot. treatments consisted...
Saline soils can limit seedling germination and growth of the crops. This research sought to identify whether cowpea varieties Pingo-de-ouro Coruja are tolerant salinity in terms biomass partitioning. A completely randomized design a 2 x 4 factorial arrangement, totaling eight treatments with four replications was used. The consisted two addition NaCl levels electric conductivity (0.0, 3.3, 6.6 9.9 dS∙m-1). variables analyzed were percentage (PG), first count (FGC), speed index (GSI),...
O presente trabalho teve como objetivo investigar a percepção de pequenos agricultores em relação às consequências do desmatamento facilitador da degradação solo, adotando áreas estudo três comunidades rurais localizadas no município Patu, estado Rio Grande Norte. A escolha das deu-se função estarem uma área com declividade acentuada, possibilitando ocorrência terras pelo uso inadequado solo. Como instrumento coleta dados foi utilizado à aplicação formulários aos agricultores. Os...
Abstract: The objective of this study was to evaluate the production castor bean seedlings due different volumes containers and substrates. work conducted from May June 2014, in nursery State University Paraiba, Campus IV, Catole do Rocha, PB. experimental design a completely randomized design, adopting 4 x 2 factorial scheme, with 6 replicates, four container volumes: (polyethylene plastic bags capacity 1000 dm³; polyethylene 500 tubes 300 dm³ disposable cups 270 dm³) two types substrates...
