(Accuracy 2012 - Proceedings of the 10th International Symposium on Spatial Accuracy Assessment in Natural Resources and Environmental Sciences, 2012) [Trabalho apresentado em evento]This work presents an uncertainty analysis applied to the results of an ecological model. This model describes the development of submerged macrophytes colonization in a brazilian reservoir, between Sao Paulo and Parana ... -
Improving soil fertility with lime and phosphogypsum enhances soybean yield and physiological characteristics
(Agronomy for Sustainable Development, 2022) [Artigo]In tropical no-till systems, applying lime (L) and phosphogypsum (PG) on the soil surface may be a potential strategy for reducing soil acidification and improving soybean root growth, thereby enhancing plant nutrition and ... -
Weed interference in Marandu palisade grass pastures under renewal or maintenance conditions
(Revista Brasileira de Engenharia Agricola e Ambiental, 2022) [Artigo]The presence of weeds as a consequence of pasture degradation is one of the main problems facing livestock worldwide. Thus, knowing the interference aspects and the appropriate time for weed management is essential for ... -
Soil—Plant Relationships in Soybean Cultivated under Conventional Tillage and Long-Term No-Tillage
(Agronomy, 2022) [Artigo]Soybeans [Glycine max (L.) Merrill] have great economic prominence in the world, and soil management systems can directly interfere with their yield through changes in soil physical-hydric properties. Thus, the aim of this ... -
Deep Soil Water Content and Forage Production in a Tropical Agroforestry System
(Agriculture (Switzerland), 2022) [Artigo]Agroforestry systems integrating tree and forage growth are important for maintaining soil health but may change the soil’s physical-hydric properties. Our goal was to investigate the impact of introducing Eucalyptus trees ... -
Close-spaced plant arrangement optimizes castor biomass and seed yields in tropical fall–winter conditions
(Crop Science, 2022) [Artigo]The high seed yield and optimum harvesting of short-height castor (Ricinus communis L.) genotypes have enabled its large-scale cultivation and introduction in the Brazilian cropping systems. Thus, studies to optimize plant ... -
Adaptability and Stability of Safflower Genotypes for Oil Production
(Plants, 2022) [Artigo]The study aimed to analyze the agronomic performance of 11 safflower genotypes using adaptability and stability methods, while identifying safflower genotypes with stable behavior and a high grain yield in different ... -
Feasibility of early fertilization of maize with 15 N application to preceding cover crop
(European Journal of Agronomy, 2022) [Artigo]Early nitrogen (N) application on live cover crops or their residues is a potential alternative for supplying N demand while enhancing the yield of subsequent cash crops in tropical regions. The objective of applying N on ... -
Exploring the synergism between surface liming and nitrogen fertilization in no-till system
(Agronomy Journal, 2021) [Artigo]Surface liming to correct soil acidity may have limited effectiveness in subsurface layers in no-till systems (NTS). The possibility of downward movement may be increased when liming is combined with fertilization with ... -
Turning biennial into biannual harvest: Long-term assessment of Arabica coffee–macadamia intercropping and irrigation synergism by biological and economic indices
(Food and Energy Security, 2022) [Artigo]Intercropping that involves coffee (Coffee arabica L.) and macadamia (Macadamia integrifolia Maiden & Betche) can achieve the complementarity between component crops aiming at better use of natural resources, hence resulting ... -
Leaching potential of S-metolachlor in a medium-textured Oxisol soil with bioindicator plants
(Revista Brasileira de Engenharia Agricola e Ambiental, 2022) [Artigo]Information about the impact of herbicides in the soil based on the growth of bioindicator species is extremely useful in developing crop management strategies. Therefore, this study aims to evaluate the leaching potential ... -
Effect of intercropping between tropical fodder plants with corn and nitrogen fertilization on soil physical properties
(Revista de Agricultura Neotropical, 2021) [Artigo]The use of diversified crop systems within the same area has received attention as an alternative to monoculture and benefits soil and yield. This study evaluates the effect ofnitrogen fertilization and tropicalfodder ... -
Potassium-magnesium imbalance causes detrimental effects on growth, starch allocation and Rubisco activity in sugarcane plants
(Plant and Soil, 2022) [Artigo]Background and aims: While there is abundant literature on the antagonistic interaction between potassium (K) and magnesium (Mg) during root uptake and transport, there is, however, little published data on the interaction ... -
Soil application of silicon enhances initial growth and nitrogen use efficiency of Arabica coffee plants
(Journal of Plant Nutrition, 2022) [Artigo]Nitrogen (N) plays a fundamental role in the initial growth of the Arabica coffee plant whereas silicon (Si) is key in enhancing performance of the plant through promoting N-use efficiency (NUE). This study evaluated the ... -
Maize and sorghum root growth and yield when intercropped with forage grasses
(Agronomy Journal, 2021) [Artigo]Integrated crop–livestock systems that intercrop forage crops with grain crops are effective for increasing forage production and improving nutrient cycling and soil health. However, the potential for root competition when ... -
Hormesis effect of 2,4-d choline salt on soybean biometric variables
(Chilean Journal of Agricultural Research, 2021) [Artigo]Auxin-based herbicides, such as 2,4-dichlorophenoxyacetic acid (2,4-D), are lethal to plants at higher doses, but can enhance plant growth at nontoxic concentrations. The stimulating effect of low doses of a substance ... -
Potassium bioavailability in a tropical kaolinitic soil
(Agronomy, 2021) [Artigo]Some plant species are able to acquire non-exchangeable forms of K, which improve K availability and cycling in cropping systems, and which may explain the lack of response to K. However, this would not be expected in soils ... -
Cover crop and early nitrogen management for common bean in a tropical no-till system
