Soybean is one of the main species of cultivated plants in the world, having an important role in the food sector and as raw material. Several types of stressors cause losses in soybean, such as nematodes. Using drones, the study determined the best spectral band for the detection of two types of nematodes. Read More →

Evaluation of 42 rootstocks behavior in Citriculture

Citrus culture is the cultivation of citrus fruits, especially orange and lime. This practice is one of the most important sectors of agribusiness in Brazil and generally utilizes the rootstock technique. The analysis evaluates the behavior of 42 rootstocks of “Valência Late” orange trees during the seedling. The results point to some possible alternatives for new rootstocks that will be field tested.

Dairy production is one of the most important sectors of the Uruguayan economy. The genetic disorders of the “Holstein” breed cause production problems, compromising the sustainability of the milk production. The genomic monitoring of carrier animals is necessary to avoid the spread of lethal and semi-lethal alleles and to reduce the economic losses to dairy farming. Read More →

Latitude and seasons influence the tick count in cattle

Being one of the main parasites of cattle, ticks cause losses to livestock farmers. It has been shown that latitude and season interfere with tick counts: higher latitudes tend to have less tick infestation, as well as in winter, while in spring there is a higher infestation. Read More →

Electrical stunning in Jundiá fish keeps meat quality and allows humane slaughter

The parameters for electrical stunning in Jundiá fish and its effects on muscle pH and rigor mortis indicates no significant differences in the parameters of meat quality – it allows for discussion and refinement of current practices in the slaughter of fish, also considering their well-being.

Study points out microorganisms activating in the remediation of soil degraded by agrochemistics

Herbicides such as hexazinone are widely used in crops around the world. With the objective of selecting hexazinone-tolerant microorganisms that have the capacity to solubilize phosphate and prepare inoculants associated with the plant in the remediation of soil contaminated with hexazinone, researchers carried out a research based on 20 soil samples. The results present an alternative to help improve soil quality. Read More →

Research monitoring waste levels of the Glyphosate Herbicide

Used in agriculture, glyphosate is an herbicide capable of controlling a wide range of weeds. However, its use can lead to the occurrence of residues, whether in conventional or genetically modified crops. Researchers analyzed samples of soybeans and corn and cotton seeds, in commercial areas in the harvests of 2012/2013 to 2017/2018, in different Brazilian agricultural regions in order to monitor the levels of residues of glyphosate and its metabolite, after different managements. The results showed undetected or minimal residue rates, confirming that the safety profiles determined by Brazilian regulatory agencies are followed. Read More →

Research analysis the viability of crop-livestock integration system

Agricultural production systems such as integrating farming and livestock are being presented as an alternative to traditional planting. Seeking to analyze the economic viability and financial risk of applying this system, researchers developed a research that analyzed a crop-livestock integration project focused on the production of beef animals. Using the Monte Carlo simulation, the results demonstrated the viability of the system, compared to others. Read More →

Research analyzes honey production by stingless bees in the peruvian amazonia

Meliponiculture is the rational breeding of stingless bees. Being a common practice in Latin America, the research sought to analyze the production and collect data on the physical-chemical and microbiological characteristics of the honey produced by these techniques, generating greater knowledge about the honey produced.
