Utilizando Aprendizado de Máquina Explicável para Previsão de Severidade de Ferrugem Asiática da Soja
type: item
description: Asian rust is a disease caused by the fungus Phakopsora pachyrhizi; it has the soybean as one of its hosts, and its appearance depends on multiple enviromental variables. This paper proposes using state-of-the-art machine-learning models for predicting the severity of Asian rust on soybean crops. We combine geological and meteorological data with datasets on soybean crops to obtain a dataset that enables better exploring the capabilities of the models. In particular, we focus on explainable models. The extended dataset, in combination with the models, enabled achieving a good accuracy for prediction of Asian rust severity for several crops in several Brazilian cities.

Desenvolvimento de um aplicativo para o planejamento e estimativa das perdas na colheita de soja
type: item
description: Soybean harvesting is performed mechanically, and this stage has a high hourly operating cost. During harvesting, losses occur due to different factors ranging from poor harvester adjustment to the way it is operated. We propose the development of an application to assist in decision-making in the planning of mechanized soybean harvesting called ColheSoja, with features to perform the planning of mechanized harvesting, as well as to estimate losses and harvesting costs. The application becomes an important tool to assist in decision-making by farmers and field technicians, aiming at the planning and management of mechanized soybean harvesting.

Análise experimental da complexidade do problema da minimização da consanguinidade em sistemas de acasalamento
type: item
description: Animal breeding relies on mating systems to produce the best possible herd’s next generation. Besides expected genetic and economic gain, keeping low inbreeding levels is important to avoid problems related to inbreeding depression. This work aims to begin studying the complexity of that problem through an approach that combines linear programming with branch-and-bound to investigate the average execution time for obtaining the problem solution. The results indicate that the problem seems to be computationally intractable.

Data assimilation in crop models: old experiences in new contexts
type: item
description: Data assimilation has been widely used for improvement of crop models’ estimates, for example to incorporate the effects of external events or compensate calibration errors in large areas. There are then many well-established approaches for those who want to take advantage of satellite imagery and reduce uncertainty or model error. However, its use in different contexts requires exploring aspects of the pipeline that are not as well established, such as which variables to assimilate or how to ascribe uncertainty to observations or model estimates. In this study, we assess the impacts of different noise levels for performing data assimilation in a tomato growth model, with artificial observations of fruit and mature fruit biomass.

Sistema de recomendação de adubação com efluente de esgoto tratado em manejos multicondições para fertirrigação de milho
type: item
description: Sewage treatment from rural areas is precarious in Brazil, causing environmental and health impacts. The biodigester septic tank has shown itself as a solution, producing treated sewage effluent (TSE) that can be reused in fertilization. Some works with TSE in agriculture targets specific conditions, but they do not translate into a generic and algorithmic solution capable of dealing with multiple conditions of cultivation as well as TSE production and quality. In this article, we present a new multi-condition method to TSE reuse in recommendations for corn fertirrigation. The definition of a multicondition flow enabled the development of a responsive application (Web app). The simulations and comparisons carried out resulted in doses similar to the technical recommendations, a bit higher than the literature for nitrogen and slightly lower for potassium and phosphorus. The derived recommendation system constitutes a practical solution for EET reuse in small-scale agriculture.

Peanut Loss Predictions Using Random Forest and Soil Data
type: item
description: This work aimed to evaluate the Random Forest algorithm performance to predict mechanical digging loss of the peanut crop. Four approaches were tested: only soil texture data, soil texture + TPI, soil texture + TWI, and soil texture + TPI + TWI. The model's performance was evaluated regarding precision (coefficient of determination) and accuracy (mean absolute error). The results found in this work proved promising in predicting peanut digging losses. Our models achieve results with an approximate 100 kg ha-1 prediction error. In addition, incorporating one or more topographical indexes in conjunction with soil texture data as features notably improves the models' precision and accuracy.

Desenvolvimento de um controlador de lógica fuzzy para irrigação por gotejamento
type: item
description: Drip irrigation is a technique that can contribute to food security by increasing crop productivity and reducing water consumption. One of the challenges faced by farmers is determining the optimal time and amount of irrigation for each crop and environmental conditions. Inadequate irrigation management can lead to water losses through evaporation or deep percolation, as well as water stress or excess water in plants. In this context, this work proposes a fuzzy logic algorithm for drip irrigation that can adjust the time and irrigation interval according to the crop development phase, soil texture, evapotranspiration and rainfall. The experiments demonstrate that the controller is capable of estimating the irrigation time and interval, considering the input variables defined in the model. The controller contributes to more efficient and sustainable drip irrigation, as it avoids water waste and water stress on plants. This also facilitates management, as it reduces the need for human intervention and provides intelligent feedback for decision making.

Peanut yield estimation models using Machine Learning techniques and Google Earth Engine
type: item
description: The estimation of the yield for the peanut crop can be performed by visual methods, traditional destructive methods, which are time consuming, laborious and with imprecise predictions. Thus, the objective was to use SR techniques and Artificial Neural Networks (ANN) in the development of an innovative method for yield prediction in the peanut crop. The experiments were conducted in the state of São Paulo in the 2021/2022 crop season, in 6 commercial farms in sandy and clayey areas. The RBF and MLP networks were able to estimate peanut yield with an accuracy below 1000 kg/ha. GNDVI was a better vegetation index with estimation accuracy of 238.7 and 296.54 for the RBF and MLP networks, respectively.

Sensoriamento proximal aplicado ao algoritmo SAFER para estimativa de massa de forragem em sistema silvipastoril
type: item
description: Forage mass availability directs herd sizing, based on this, the aim of this study was to evaluate a method to estimate pasture mass in a silvopastoral system, through proximal sensing applied to the Simple Algorithm for Evapotranspiration Retrieving (SAFER). For this, forage collections were carried out, as well as the collection of climatic data and reflectance data with a proximal sensor. The data served as input for SAFER and then regression models were generated between pasture variables and SAFER results. SAFER was able to express forage behavior in a promising way, and allowed the creation of an estimation model with high precision for silvopastoral system.

Aplicação de Internet das Coisas (IOT) e Inteligência Artificial (IA) para gestão de aviários e melhorias do desempenho produtivo: um estudo de caso em produtores de uma cooperativa agroindustrial
type: item
description: A Internet das Coisas (IoT) e a Inteligência Artificial (IA) compreendem inovações tecnológicas conhecidas como tecnologias 4.0 que permitem a fusão dos domínios físicos, digitais e biológicos e que se destacam pela velocidade, amplitude e profundidade de suas aplicações. A aplicação das tecnologias 4.0 se deu inicialmente para a indústria de transformação, mas, atualmente, já vêm sendo adotadas em diversos setores, como é o caso do setor agropecuário. Neste setor, estas tecnologias têm um alto potencial para permitir o desenvolvimento, remodelar significativamente as cadeias de valor e contribuir muito para sistemas alimentares mais produtivos, resilientes e transparentes. No Brasil, há um grande público que ainda não adota ou considera este tipo de tecnologia em seu processo produtivo. No que diz respeito à pecuária, especialmente à cadeia produtiva de frango de corte, identifica-se um desafio na padronização da produção, em especial, quanto à desuniformidade do peso das aves ao final de seu ciclo de engorda, que ocorre devido a fatores ambientais e de manejo. Este artigo tem o propósito de apresentar informações gerais sobre um projeto piloto de adoção de IoT e IA em 15 aviários de produtores rurais associados a uma cooperativa do sul do Brasil, para o monitoramento constante de aves, permitindo tomadas de decisões de manejo mais assertivas, tendo como foco o aumento da qualidade dos frangos produzidos, maior lucratividade, maior controle sanitário dos ambientes de produção e atendimento aos preceitos do bem-estar animal. Ao final do projeto, com a solução, foi possível identificar um aumento de produtividade de 7% e os desafios para a difusão.

Imagens de Raios X e YOLOv8 para Avaliação Automatizada, Precisa e Não Destrutiva da Qualidade de Sementes Braquiária (Urochloa brizantha)
type: item
description: Seed quality is crucial in agriculture. Companies that produce seeds are concerned about finding rapid tests that accurately assess seed vigor, and the time it takes to conduct these tests is a limiting factor. Here we apply the YOLOv8 model to quickly, automatically, and non-destructively evaluate the physiological potential of seeds. The proposed method uses radiographic images of brachiaria seeds (Urochloa brizantha) to identify and classify them based on their physiological quality. The YOLOv8 network was trained with a dataset of seed images, and the results demonstrated high accuracy in identifying and classifying the seeds, with mAP50 and mAP50-95 metrics of 90.6% and 90.1%, respectively, for all classes.

Kernel Maps of the Bactrocera carambolae Occurrence in Amapá, Brazil
type: item
description: This work analyzes the spatial distribution of the Bactrocera carambolae occurrence between 2014 and 2019 in Amapá, Brazil. They monitored the quarantine pest present using traps distributed throughout the state. The technicians checked traps every fifteen days, recorded the occurrence, and sent the information to MAPA. To analyze the spatial distribution, we evaluated the degree of randomness of the traps using the non-homogeneous K function. Subsequently, we applied the quartic kernel function on the occurrences and the simulated occurrences, considering the non-homogeneous phenomenon and having the population per census tracts and highways as covariates. The results showed that we could use the method to monitor the pest on a regional scale.

Exploring conditional missing patterns for automated bacteria identification using MALDI-TOF MS data
type: item
description: Training classifiers for automated bacterial identification using MALDI-TOF fingerprints requires addressing class-conditional missingness patterns (CMPs). A CMP is a non-missing-at-random pattern that provides evidence for classification. One possible strategy to handle CMPs is feature stratification. This work evaluated the effectiveness of stratification in training naive Bayes classifiers for the proposed task through two experiments. The first experiment compared the predictive performance of categorical naive Bayes classifiers trained on stratified/discretized features with the performance of a Gaussian naive Bayes fitted on imputed data. The second experiment assessed the impact of class imbalance on the differences in the performance of Gaussian and categorical naive Bayes classifiers. The ANOVA results suggest that feature stratification can induce more accurate classifiers. Correlation analysis shows that class imbalance has a low influence on the difference in the performances of classifiers.

Uma arquitetura de rede neural convolucional para detecção de alvos de desmatamento na Amazônia através de imagens SAR ICEYE
type: item
description: In recent decades, solutions based on artificial satellites for observation of the earth's surface have emerged that help in the detection of deforested areas through predominantly optical technology. However, such an approach is hampered by the typical climatic conditions of the Amazon, where cloudiness makes it difficult to see some regions of interest. The use of satellites equipped with synthetic aperture radar (SAR) sensors is a viable option to overcome this inconvenience, since they are able to pass through obstacles, since they use microwaves to perform the imaging. Recently there has been an increase in the use of artificial intelligence in the task of analyzing these images in order to identify different types of land use and land cover. In this sense, the present work proposes the development of an convolucional neural network archtecture capable of contributing to the monitoring of large areas of the Amazon forest through the use of machine learning techniques in order to automatically detect deforestation patterns in orbital radar images.

Evaluating multiple regressors for the yield of orange orchards
type: item
description: Accurate fruit yield estimation is crucial for making informed decisions about harvesting, storage and marketing. However, estimating fruit yield can be challenging. Currently, yield estimation relies on labor-intensive manual counting combined with statistical methods. However, computer vision has emerged as a potential alternative by enabling automatic fruit counting, thus simplifying the process. In this paper, we assess the effectiveness of various machine learning regressors for yield forecasting based on fruit detection in images captured within the orchard. Our results indicate that deep forward neural networks outperform the other regressors examined, making them the most effective choice for yield prediction.

Machine Learning for Soil Attribute Prediction: An Effectiveness and Dimensionality Reduction Analysis
type: item
description: Traditional soil fertility analyzes are laborious, expensive, timeconsuming and produce hazardous waste. Although many works using machine learning (ML) has been done to address these issues, some algorithms and dimensionality reduction strategies require further investigation. Therefore, in this study we evaluated the potential of Support Vector Regression and Ridge regression in determining soil attributes, and compared principal components regression and partial least squares regression (PLSR). The results showed that Ridge was the most effective model. In addition, our experiments revealed that PLSR was able to achieve statistically equivalent results, and in some cases superior to the baseline, but using a much smaller average number of components.

Classificação de predadores de abelhas melíferas utilizando redes neurais convolucionais e transferência de conhecimento
type: item
description: The preservation of biodiversity is a crucial issue in a world increasingly threatened by environmental changes and the loss of natural habitats. In this context, beekeeping and bee conservation have proven to be essential for the pollination of various agricultural crops and for the maintenance of ecosystems. Bees are important pollinating insects for agriculture and the environment. However, they are also vulnerable to predators such as ants, wasps and flies. Identifying bee predators is important to protect hives and ensure successful pollination. In this article, we present a computational model based on artificial intelligence (AI) to differentiate bees from predators, where it is trained from a database of images of bees and predators. The model uses different feature extractors based on convolutional neural networks (CNNs) to extract features from the images, such features are then classified by different pattern classifiers, such as support vector machine (SVM), K-Nearest Neighbors (k-NN) and multilayer neural network (MLP). The analysis of the experimental results showed that the proposed model obtained a satisfactory accuracy in relation to the Acucária metric, obtaining a value of 86.94%.

Automatic Segmentation of the Self-organizing Map to Support Territorial Zoning
type: item
description: This paper proposes an algorithm for analyzing clusters of thematic maps with ordinal categorical classes to support territorial zoning. The proposed method combines the Self-Organizing Map with graph segmentation techniques for data clustering. The approach was evaluated with synthetic data and applied to the environmental zoning of the Alto Taquari basin, MS/MT. The results showed the ability of the algorithm to separate the data into unimodal differentiable groups.

Comparando a Eficiência de Redes Neurais Convolutivas para Detecção de Frutos em Pomares de Laranja
type: item
description: Given the importance of citrus farming in Brazil's economy, one of the global powers in this sector, it is essential to constantly renew cultivation techniques to make production more efficient. This study tests the efficiency of the YOLOv8 neural network for object detection, with the purpose of obtaining a more accurate orange crop estimate. The overall performance presented by the network was satisfactory, but it did not allow us to demonstrate that it is better than its previous version YOLOv5 in all metrics.

Sistema de baixo custo para determinação de umidade e massa específica aparente de grãos
type: item
description: This study aimed to develop an affordable hectoliter moisture and weight analyzer suitable for small-scale farmers. The equipment was calibrated for two grain types, namely corn and beans, enabling the determination of moisture content. The moisture levels ranged from 6.18 to 11.08% for corn and from 8.21 to 13.75% for beans, as compared to the oven method. In terms of hectoliter weight determination, the analysis yielded an r² value of 0.928 for beans and 0.926 for corn, when compared to the GEHAKA hectoliter weight kit. The production cost of approximately 595 reais ensures accessibility and feasibility for small-scale agricultural implementation.

Reconhecimento de padrões de produtividade de milho com a abordagem few-shot learning
type: item
description: Estimating yield is of particular interest in agriculture, and machine learning (ML) techniques have contributed to making it happen in a faster and more efficient way. Considering the frequent difficulty in acquiring large-scale agricultural data, few-shot learning (FSL) methods have emerged as an alternative. The goal of this work was to evaluate the use of different composition methods of images acquired by Remotely Piloted Aircraft (RPA), associated or not with plant height, for classifying maize yield, using classical ML techniques and FSL approach. The results of using FSL showed that the model with a siamese network can be viable without using the average height of the plant.
