Several technical, economic and/or social factors contribute to good or bad performance of irrigated public perimeters. One of the key aspects in the analysis of these factors is the ability to monitor them through calculation of measurable parameters. Thus, the objective of this study was to analyze technical and socioeconomic indicators of irrigated public perimeters of the region of Baixo Jaguaribe, in the s...
The present work evaluated the productivity and efficiency of the use of the water in the culture of sorghum forager (BRS Black Tip) under different blades of irrigation (50; 75; 100; 125 and 150% of the evapotranspiration of the culture, ETc) associates the different levels of covering deceased (mulch) (0.00; 2.50; 3.75; 5.00 and 6.25 cm). The experimental delineation was made use in subdivided parcels, 5 x 5 ...
The viability index of forage sorghum (BRS Ponta Negra) implantation is evaluated at different irrigation laminas (50; 75; 100; 125; 150% of evapotranspiration of culture, ETC), associated to different levels of the dead coverage with carnauba palm straw (0.00; 2.50; 3.75; 5.00; 6.25 cm). Research was undertaken at the Instituto Federal de Educação, Ciência e Tecnologia do Ceará (IFCE), campus Umirim (CE), betw...
This study aimed to identify cultivation techniques with biofertilizer in greenhouse and open field with fig culture in Limoeiro do Norte-CE, including three production cycles, from October 2010 to December 2011. The experimental design was a randomized block with split plot with four replications. Treatments included a combination of 3 cultivation environments: greenhouse (EST), trellis (LT) and open field (CA...
Para o sucesso do diagnóstico nutricional é interessante que a avaliação nutricional das plantas seja fundamentada em dados locais e como alternativa tem sido utilizado o Sistema Integrado de Diagnose e Recomendação (DRIS). Objetivou-se com este trabalho estabelecer normas DRIS preliminares para a cultura da banana na região do Baixo Jaguaribe, CE, com base em banco de dados com resultados de análise foliar. Fo...
