1. Sensitivity analysis of the AquaCrop model for wheat crop in Campos Gerais region, Paraná
ABSTRACT The use of crop modeling can be useful to understand the interactions between the soil-plant-atmosphere system. The objective of this study was to evaluate sensitivity analysis of the AquaCrop model parameters for wheat crop in the Campos Gerais Region. The varietie tested was TBIO Sinuelo in Castro, Ponta Grossa and Itaberá cities. The analyzed pa

2. Growth and quality of Brazilian pine tree seedlings as affected by container type and volume
Resumo Araucaria angustifolia (Bert.) O. Kuntze (Araucariaceae), popularmente conhecida como araucária e pinheiro brasileiro, pode ser cultivada em função de suas sementes comestíveis (pinhões), propriedades medicinais e atributos ornamentais. O objetivo foi avaliar o crescimento de parte aérea e radicular e a qualidade geral de mudas de A. angustifoli

3. Estimating Above-Ground Biomass of Araucaria angustifolia (Bertol.) Kuntze Using LiDAR Data
ABSTRACT The objective of this study was to test the performance of canopy data obtained from Airborne Laser Scanner (ALS) in generating estimates of above-ground biomass (AGB) of Araucaria angustifolia (Bertol.) Kuntze individuals. A cloud of ALS points located in a fragment of native urban forest in Curitiba, Paraná was used. The procedures consisted of:

4. A GENERALIZED ABOVEGROUND BIOMASS MODEL FOR JUVENILE INDIVIDUALS OF Rhododendron arboreum (SM.) IN NEPAL
ABSTRACT Carbon in the juvenile plants contribute significant share to the total carbon stock in forests. A precise estimate of aboveground biomass of the juvenile stages of trees is therefore very important. We developed a generalized allometric biomass model for the prediction of aboveground biomass of the juvenile individuals of Rhododendron arboreum (Sm.

5. Anthropogenic Disturbances Affect the Relationship Between Spectral Indices and the Biometric Variables of Brazilian Savannas
ABSTRACT According to previous studies involving biometric variables modeling using remote sensing (RS), data did not consider the effects of anthropogenic disturbance as relevant factor. The main objective of this study was to model aboveground biomass (AGB) and total wood volume (TWV) of Brazilian Savanna biome using vegetation indices (VI) from LANDSAT 5

6. Biometric characteristics and canopy reflectance association for early-stage sugarcane biomass prediction
ABSTRACT: Knowing the spatial variability of sugarcane biomass in the early stages of development may help growers in their management decision-making. Proximal canopy sensing is a promising technology that can identify this variability but is limited to quantifying plant-specific parameters. In this study, we evaluated whether biometric variables integrated

7. Estructura, composición florística y almacenamiento de carbono en bosques nativos del páramo de Anaime, Tolima, Colombia
Abstract Páramos have a high environmental importance due to their high plant and animal endemism, water regulation and carbon storage. In this work, the structure and composition of the tree vegetation were characterized as well as carbon storage in aboveground biomass and the potential reduction of emissions by deforestation were estimated prioritizing th

8. Decomposition and Nutrient Release of Cover Crops in Mango Cultivation in Brazilian Semi-Arid Region
ABSTRACT Knowledge of the decomposition dynamics of aboveground phytomass and its release of nutrients in mixtures of cover crops as well as the impact on the soil tillage system is fundamental for the sustainable management of agroecosystems. This work aimed to evaluate whether soil tillage and the choice of cover crops cultivated in the interrows can be te

9. Response of vegetation to sheep dung addition in a degraded Cerrado area
RESUMO O Cerrado é o segundo maior bioma do Brasil, sendo este um ‘hotspot’ de biodiversidade. A construção de usinas hidrelétricas dá origem a áreas degradadas, muitas vezes desprovidas de vegetação, denominadas “áreas de empréstimo”. Ovinos excretam grande parte dos nutrientes que ingerem, entre eles fósforo, cálcio, potássio, nitrogê

10. Simultaneous Equations to Estimate Aboveground Biomass of Pinus caribaea var . hondurensis
ABSTRACT This study aimed to develop equations to predict the biomass of trunks, branches, needles and total individual biomass for Pinus caribaea var. hondurensis . A simultaneous equation system was also adjusted. Twenty (20) trees from the experimental area of the State University of Southwest Bahia (UESB), Vitória da Conquista, Bahia, Brazil, were meas

11. Resistance of sugarcane cultivars to Mahanarva fimbriolata
ABSTRACT The spittlebug Mahanarva fimbriolata (Stål) (Hemiptera: Cercopidae) is one of the most important pest of sugarcane in Brazil. Population control measures are currently restricted to the use of chemical insecticides and the fungus Metarhizium anisopliae, in part because very little information exists regarding the resistance of sugarcane cultivars.

12. Performance of Flooded Rice Grown in Succession to Winter Cover Crops
ABSTRACT: Mean grain yield of flooded rice in southern Brazil has increased in recent years due to the use of high-yield cultivars and improvement of crop management practices. Nevertheless, stagnation in grain yields has been observed in some rice-producing regions. Adoption of conservation tillage systems based on cover crops may be a strategy to increase
