13. Biochar in sugar beet production and nutrition
RESUMO: O processo de pirólise da biomassa pode ser uma alternativa para o uso agrícola de lodo de esgoto. Este trabalho objetivou avaliar o uso de biochar produzido a partir da mistura de lodo de esgoto e bagaço de cana (BB, 1:1 relação lodo de esgoto e e bagaço de cana) na produção e nutrição de beterraba (Beta vulgaris L.). Conduziu-se um exper

14. A MEASUREMENT SYSTEM BASED ON LiDAR TECHNOLOGY TO CHARACTERIZE THE CANOPY OF SUGARCANE PLANTS
ABSTRACT Laser sensor applications associated with LiDAR (Light Detection and Ranging) technology on platforms allow the evaluation of crop and forest biomass in a non-invasive way. This study presents the development of a measurement system based on LiDAR technology aimed at the proposed assessment of the height of sugarcane plants during the pre-harvest pe

15. Identifying agriculture land acquisitions for alleviating future food security concerns
Abstract The total available land for food, fuel, or forests is finite, while land demand is increasing and expected to increase further in the coming decades; resulting in deterioration of food security. Therefore, the corporate world adopted a solution of acquiring international agricultural land. Consequently, the global demand for land has progressively

16. THE TECHNOLOGICAL LEVEL OF AGRICULTURAL MECHANIZATION IN THE STATE OF CEARÁ, BRAZIL
ABSTRACT Agricultural mechanization is a significant factor of agricultural modernization, but there are few data on the technological levels of this mechanization in the State of Ceará, Brazil. To study this topic, we designed a structured questionnaire, and interviews were conducted across the state. The survey data made it possible to calculate an index

18. IPRDataCol - software for field labelling and data storage
Abstract The software IPRDataCol was developed in 2017 at the Instituto Agronômico do Paraná (IAPAR) by a research group (Nucleo1) studying information technology applied to agricultural research. Due to the software architecture, whether the label-generating nor the data capture module use any native database, i.e, the program can be used directly from po

19. Sequence-related amplified polymorphisms (SRAPs) reveal genetic diversity and variation regions in upland cotton (Gossypium hirsutum L.) in China
Abstract The lack of genetic diversity is an obstacle for genetic improvement of upland cotton in China; thus, new technologies must be developed to produce more polymorphic molecular markers associated with agricultural traits of the existing resources for breeding. A highly efficient and economical technology of sequence-related amplified polymorphism (SRA

20. USE OF USLE/ GIS TECHNOLOGY FOR IDENTIFYING CRITERIA FOR MONITORING SOIL EROSION LOSSES IN AGRICULTURAL AREAS
ABSTRACT The assessment of land use and occupation is essential for predicting soil loss due to water erosion. The objective of this study was to determine criteria for monitoring soil loss in agricultural areas using the Universal Soil Loss Equation (USLE). Soil loss data were intersected with USLE factors and slope using geoprocessing techniques for the Sa

21. ASSEMBLY OF A REMOTELY PILOTED AIRCRAFT OF LOW COST APPLIED TO AGRICULTURE
ABSTRACT: The remotely piloted aircraft (RPA) have great applicability in agriculture. Although it is a technology that has been developed for many years, in the field of agriculture it passed unnoticed for a long time. The high cost of acquisition is still a limiting factor for small and medium-sized farmers. In this way, this study had as objective to deve

23. CROP COEFFICIENT REGIONALIZATION FOR IRRIGATED AGRICULTURE PLANNING IN MARANHÃO STATE -BRAZIL
ABSTRACT: Irrigated agriculture has emerged as a necessary technology to achieve greater productivity, mainly by supplying the water requirements of agricultural crops in critical periods, especially for those regions where natural rainfall is insufficient to meet these requirements. The daily water consumption of crops is strongly influenced by local weathe

24. Sociomaterial Practices: Challenges in Developing a Virtual Business Community Platform in Agriculture
Abstract Virtual business communities (VBC) are virtual networks of people who share common interests and comprise online software platforms that enables the fast exchange of information, collaboration and business interactions. From 2011 to 2015, we developed a design science research to create a VBC platform for an agricultural cluster of flower growers in
