ABSTRACT The precocity of cowpea is important because it indicates the possibility increasing and/or stabilizing production in regions with long periods drought. aim this study was to evaluate genetic variability and select extra-early progenies. Fifteen F3:6 progenies were evaluated 2014 while sixty-two F7 2015. Two commercial cultivars used experiments performed irrigated perimeter Baixo Acaraú, Marco, CE. following characteristics evaluated: number days for flowering (NDF), maturity...

A utilização de espécies oleaginosas constitui uma alternativa à busca crescente por biocombustíveis, fazendo com que o pinhão manso venha ganhando destaque pela qualidade do seu óleo e rusticidade. Surge assim demanda pelo desenvolvimento cultivares desta espécie para isso conhecimento sua variabilidade genética é fundamental. Objetivou-se presente estudo avaliar a diversidade 23 acessos coletados em diferentes regiões Brasil. Os DNAs dos foram extraídos analisados meio 12 iniciadores ISSR....

Moisture correction of fresh pods cowpea genotypes has been used to correct weight differences from the same harvest. Correction is made by method soaking and grains in water. This study verifies need for moisture estimate yield production green grains. Sixteen were evaluated pod mass, grain hundred index, yield, two municipalities, Pentecoste Marco, Ceara State, Brazil. For correction, a sample ten was collected, weighed, soaked Samples weighed until constant wet mass. Subsequently, samples...

The eggplant, a major vegetable crops in cultivation Brazil the world has presented significant increase both consumption and consequently their area.Knowledge of phenology culture, as well knowledge

A agricultura, especialmente o setor de fruticultura, possui considerável importância na economia cearense e do Nordeste como um todo, apontando para a necessidade conhecimento características relacionadas à comercialização frutas assim estudos sobre comportamento dos preços destes produtos.O padrão sazonalidade tendência produtos originários deste significativa no contexto planejamento agrícola.Assim, este trabalho teve objetivo analisar das principais hortaliças-fruto comercializados...

The evaluation of segregating populations in plant breeding programs is an onerous and time-consuming process. Early identification with genetic potential can be done by m + a methodology. However, the possibility modification traditional methodology order to make it more efficient, that is, faster cheaper, was envisaged. Thus, objective this study compare gains obtained both methodologies, one proposed modification. For this, ten bean-cowpea were evaluated at two distinct levels homozygous...

The protein content of the cowpea has proved to be very variable, especially green grain. aim this study, therefore, was obtain information on influence environment and genetic variability total (TPC) grain, as well evaluate effects production components variable. Sixteen genotypes were evaluated in two environments (Pentecoste Acaraú) state Ceará, a simple factorial scheme (16 x 2) for eight content. grain collected while still (after filling complete - stage R5) quantification carried out...

The banana cultivation is an activity of great importance worldwide.The the most produced fruit in world, representing 19% total production and has largest planted area, with more than 10 million hectares.Potassium chloride was chosen input to exchange ratio, as it important significance crop production, its use fundamental product quality.In period 2009-2013 there a reduction amount hundreds required take ton potassium chloride.The ratio between price Pacova potash registered improvement...
