1. FERTILIZER RECOMMENDATION METHODS FOR PRECISION AGRICULTURE – A SYSTEMATIC LITERATURE STUDY
ABSTRACT Spatial variability management of soil chemical attributes is one of the approaches to be employed in the face of the constant challenge of increasing agricultural yield to meet world demand. In this sense, precision agriculture has as one of its tools the application of inputs at varying rates, which seeks to determine the ideal amount of fertilize

2. Micronutrient content and accumulation in leaves and bunches of black pepper during two crop cycles
ABSTRACT A comprehensive knowledge about micronutrient dynamics in leaves and bunches of black pepper is needed in order to proper diagnose nutrient needs, and thus facilitate fertilization management. This study aimed to evaluate micronutrient concentration and accumulation in leaves and bunches of black pepper bunches to understand the crop nutritional dem

3. Síntese de nanopartículas de prata (AgNPs) por Fusarium concolor e a inibição de fitopatógenos
RESUMO The use of nanoparticles (NPs) in agriculture represents an important technological innovation, which can be employed in the production of nanofertilizers, nanocides or pesticides encapsulated in nanoparticles for controlled release. Silver NPs are recognized for their applications in agriculture, biotechnology and medicine. The objective of this pape

4. DESIGN AND IMPLEMENTATION OF FLC APPLIED TO A SMART GREENHOUSE
ABSTRACT Greenhouse cultivation needs an accurate modelling and an optimised control system to ensure an adequate microclimatic condition for plants. It represents a complex task due to the high number of input factors. For this reason, an improved intermediate modelling was established under the platform of the MATLAB/Simulink environment to simulate the en

5. CHANGES IN PHYSICAL QUALITY OF OXISOLS UNDER DIFFERENT MANAGEMENT SYSTEMS IN THE BRAZILIAN CERRADO
ABSTRACT Soil compaction in agricultural areas has greatly increased in recent decades due to intensive farming practices, including short-cycle crops and machinery intensification. This study aimed to evaluate the impacts of management systems on the physical quality of a dystrophic Yellow Oxisol, in the Cerrado region of Brazil. Treatments consisted of fiv

7. IMPORTANCE OF CROP PRODUCTIVITY AND EQUIPMENT LIFETIME IN THE STRATEGIC AND TACTICAL MANAGEMENT OF SUGARCANE HARVESTERS
ABSTRACT Recently, Brazilian agriculture and the mechanization process have been improved and developed, particularly in sugarcane cultivation. The developed processes should adopt suitable management practices in terms of the technical, economic, and operational logistical aspects. As a management tool, the present study aimed to measure the impact of the a

8. Resistance of maize landraces from Brazil to fall armyworm (Lepidoptera: Noctuidae) in the winter and summer seasons
ABSTRACT The fall armyworm (Spodoptera frugiperda) is a major maize (Zea mays L.) pest in Brazil, whose larvae cause losses from plant emergence to harvesting stage. This pest has been controlled almost exclusively with chemical insecticides and Bt plants (transgenics); however, resistance evolution has been detected to these two control tactics. Therefore,

9. DEFICIT IRRIGATION OF SUBSURFACE DRIP-IRRIGATED GRAPE TOMATO
ABSTRACT Agriculture is one of the segments that most uses water and developments have been made to save irrigation water. Deficit irrigation is a technique that can contribute to production and water saving in agriculture. This study aimed to evaluate the viability of deficit irrigation in tomato production irrigated by subsurface drip in a greenhouse and e

10. Maize yield in an integrated crop-livestock-forestry system in south Goiás, Brazil
ABSTRACT Cerrado biome is responsible for part of Brazilian food production. However, due to inadequate soil management practices, large areas of crop and forage are degraded, leading to environmental and economic losses. A crop-livestock-forest system (CLFS) is a sustainable production strategy that integrates different cultivations. This objective of this

11. Agronomic performance of white oats cultivated under fertigation with treated sewage effluent and definition of critical limits of Normalized Difference Vegetation Index
ABSTRACT One of the benefits of irrigation with wastewater in agriculture is the reduction in the use of mineral fertilizers and the increase in crop yield. For wastewater application, the use of remote sensing can help to define specific management areas. The aim of this study was to evaluate the yield and the growth of irrigated white oats (Avena sativa L.
