1. CROP MODELING WITH LESS DATA: THE FAO MODEL FOR SOYBEAN YIELD ESTIMATION
ABSTRACT Crop growth simulation models such as WOFOST and DSSAT are useful, but require several inputs that sometimes are not available, especially in developing areas. In addition, measured data is usually time and labor-intensive. In search of faster and easier methods for soybean estimates, this study presents a lower input requiring methodology for yield

2. Crop coefficients of tropical forage crops, single cropped and overseeded with black oat and ryegrass
ABSTRACT: Crop coefficient (Kc) is the ratio between crop evapotranspiration (ETc) and reference evapotranspiration (ETo), representing the phenological effects on crop water consumption. Kc is fundamental to estimating ETc by agrometeorological methods. This research study aimed to determine Kc and ETc values for Guinea grass (Megathyrsus maximus cv. Momba�

3. Estimativa de perda potencial de soja no Paraná através de métodos agrometeorológicos para fins de seguro agrícola / Estimated potential loss of soybean in Paraná through agrometeorological methods for crop insurance
Uma das formas utilizadas em todo o mundo para minimizar os impactos financeiros ao produtor causados por eventos climáticos é o seguro rural. No Brasil, existe a necessidade de um maior investimento na análise dos riscos climáticos para a precificação do seguro agrícola, para que seja mais amplo e de melhor acesso por parte dos produtores. O objetivo

4. Integrating time series mining and fractals to discover patterns and extreme events in climate and remote sensing databases.
This thesis presents new methods based on fractal theory and data mining techniques to support agricultural monitoring in regional scale, specifically regions with sugar cane fields. This commodity greatly contributes to the Brazilian economy since it is a viable alternative to replace fossil fuels. Since climate influences the national agricultural producti

5. Computational framework to analyze agrometeorological, climate and remote sensing data: challenges and perspectives.
In the past few years, improvements in the data acquisition technology have decreased the time interval of data gathering. Consequently, institutions have stored huge amounts of data such as climate time series and remote sensing images. Computational models to filter, transform, merge and analyze data from many different areas are complex and challenging. T

6. AvaliaÃÃo da EvapotranspiraÃÃo de ReferÃncia (Eto) na Bacia Experimental do Riacho Gameleira â PE, utilizando LisÃmetro de Pesagem HidrÃulica e MÃtodos Indiretos
Evapotranspiration is very important to the water balance, originating increasing demands for quantitative information aiming the sustainable water resources planning. This work evaluates the reference evapotranspiration (ETo) in the experimental basin of the Gameleira rivulet â PE, using an hydraulic weighing lysimeter and indirect methods. The experimenta

8. Utilização de perfis multi-temporais do NDVI/AVHRR no acompanhamento da safra de soja no oeste do Parana / Use of NDVI/AVHRR time-series profiles for soybean crop monitoring in the west of Parana, Brazil
Crop yield forecasting systems are important sources of information for helping Governrnent and private institutions in agricultural trade matters. The traditional methods of crop yield forecasting norma1ly do not provide precise estimations, due to its subjectivity. The use of Geothecnology has been studied for the development of more efficient crop yield f

9. Lisímetro de pesagem hidráulica e evapotranspiração de referência por diferentes métodos no agreste pernambucano
O objetivo deste trabalho foi a construção e testar o funcionamento de um lisímetro de pesagem hidráulica com arranjo de pistão de mercúrio, e relacionar a evapotranspiração de referência (ETo) determinada pelo lisímetro com aquela estimada por modelos agrometeorológicos e por tanques de evaporação. A pesquisa foi conduzida na Fazenda Nossa Senh
