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. Grazing management under integrated crop-livestock system on physical soil attributes and grain yield soybean
ABSTRACT Integrated crop-livestock system (ICLS) can help improve the soil physical attributes, increasing the nutrients cycling and yield potential. We evaluated the effect of forage height management under ICLS on physical soil attributes and water infiltration. Field experiment was carried out for two consecutive years in a randomized complete block desig

3. Times and methods of black oat management on corn plantability
ABSTRACT The importance of maintaining straw on the soil surface is a subject widely discussed and proven in the literature. However, the effects of this straw on planting efficiency and quality still lack information. In this sense, both time and method of the black oat management influence the permanence of the straw on the soil and, thus, can interfere in

4. Water footprint of Arabica coffee from “Matas de Minas” under shade management
ABSTRACT Studies related to climate change and agricultural value chains have in common the growing concern on conserving water resources. Thus, the concept of the water footprint stands out, which measures the amount of water (in volume) necessary to produce a unit (in mass) of a given product. Among Brazilian agricultural activities, coffee farming emerges

5. 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

6. 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

7. Inoculation with Azospirillum combined with nitrogen fertilization in sorghum intercropped with Urochloa in off-season
ABSTRACT The objective of this work was to evaluate the management of nitrogen fertilization in grains of sorghum inoculated or not with Azospirillum brasilense in single crop or intercropped with Urochloa brizantha (cv. Paiaguás) in the off-season. The experimental design was a completely randomized block design with four replications, in a 2 x 2 x 3 facto

8. Tolerance of cerrado baru tree (Dipteryx alata) submitted to different doses of glyphosate
ABSTRACT Baru tree (Dipteryx alata Vogel.) is a been an alternative to establish an Integration Crop-Livestock-Forestry Systems (ICLFS), combining native species preservation with sustainable food production. However, the management procedure of herbicides for weed control is one of the major limiting factors to include tree components within ICLFS. Thus, th

9. MANAGEMENT ZONES DESIGN FOR SOYBEAN CROP USING PRINCIPAL COMPONENTS AND GEOSTATISTICS
RESUMO Na agricultura de precisão a determinação de zonas de manejo dos atributos de solo e planta, é um processo complexo que demanda o conhecimento de muitas variáveis, o que dificulta o processo de gestão e tomada de decisão. Este estudo avaliou a variabilidade espacial da produtividade da cultura da soja e de atributos químicos do solo por meio d

10. Production and post-harvest quality of mini-watermelon crop under irrigation management strategies and potassium fertilization
RESUMO A ocorrência de fontes hídricas com elevada concentração de sais se destaca como fator limitante para a produção no Nordeste brasileiro. Assim, é de fundamental importância a busca por estratégias que minimizem o efeito do estresse salino nas culturas. Neste contexto, desenvolveu-se esta pesquisa com o objetivo de avaliar a produção e a qua

11. Root morphology and kinetics of Zn absorption by roots of common bean influenced by Zn status of the root environment
ABSTRACT Understanding the kinetics of Zn absorption by roots and its effect on morphology of this organ is relevant for improving crop management, but still poorly studied for common beans. Therefore, an experiment was conducted in a hydroponic system with five initial concentrations of Zn (CZnI): 0.0; 1.0; 4.0; 16.0 and 48.0 µmol L-1. The experiment was i

12. Selectivity and residual weed control of pre-emergent herbicides in soybean crop
ABSTRACT The use of pre-emergent herbicides is important for the current agricultural production systems that present weeds resistant to herbicides. Considering the complexity of using these products, the objective of this work was to evaluate their selectivity and residual weed control in soybean crops and their effect on the weeds Amaranthus hybridus, Bide
