1. Estimated productivity of sugarcane through the Agro-Ecological Zone method
ABSTRACT The estimate of the potential sugarcane productivity through agroclimatic models aids in the agricultural planning of the crops and the quantification of the yield for a given region. For these estimated values to be considered robust there is a need for validating the performance of such models in different areas and agricultural varieties. Hence,

2. Adaptation patterns of winter wheat cultivars in agro-ecological regions
ABSTRACT: Multi-environment trials are commonly used to assess cultivar adaptation patterns under different environmental conditions and to help make effective cultivar recommendations for growers. An example of a multi-environment trial system used for cultivar recommendations is the Polish Post-registration Variety Testing System. A common approach in cult

6. Índice de sustentabilidade do perímetro irrigado Baixo Acaraú-Ceará / Sustainability index in the irrigated Baixo Acaraú -Ceará
The aimed of this work was an integrated sustainability analysis of the Irrigated Perimeter of Baixo Acaraú (PIBAU) sited in Acaraú basin, Ceará, Brazil. The analysis was labeled by an agro ecological sustainability index (ASI). The approach was based on 22 cross-over form applied to small producers that live in the PIBAU. In the irrigated areas selected

7. Desempenho agronômico e alterações morfofisiológicas de hortaliças submetidas a sombreamento para o cultivo orgânico com faixas intercalares / Morphophysiological alterations and yeld of vegetables submitted at different irradiance levels fot the organic cultivation in alley cropping system
Shading effects on morphophisiological characteristics and performance under organic cultivation with sunnhemp (Crotalaria juncea L.) hedgerows were evaluated on rocket plant [Eruca sativa (Mill)], radish (Raphanus sativus L.) and butter head and crisp head lettuce (Lactuca sativa L.), cultivated in different seasons. The experiments were carried out in Sero

9. Fuzzy set in the evaluation of the conservation state of the land use systems in the Occidental Amazonia, using beetles (Scarabaeidae) as bioindicators. / Conjuntos Fuzzy na avaliaÃÃo do estado de conservaÃÃo de sistemas de uso da terra na AmazÃnia Ocidental, usando besouros (Scarabaeidae) como bioindicadores
Currently the land is losing species much more quickly than it was some decades ago, and the human being is the main causer of this extinguishing. Biodiversity is in the basis of all survival human being, therefore it is indispensable to keep the evolution processes of the alive world acting in the regulation of the great physico-chemical equilibrium of the
