One of analytical techniques that enables precise chemical analyzes with speed, low cost and little sample manipulation is near-infrared spectroscopy - NIRS. The interest in NIR spectroscopy has grown remarkably and this technique has been recognized as a powerful tool for quantitative and qualitative analysis of chemical and physical parameters. Besides these features, the methodologies based on NIR spectroscopy have the following inherent properties: 1) allows simultaneous analysis of multi

A few years ago the carmine cochineal was introduced in the Northeast of Brazil, and its population slowly expanded across the forage cactus plantations of that region. With the occurrence of suitable growth conditions during the drought of 2012, such scale insect reached the condition of pest, and decimated or compromised the productivity of thousands of hectares of forage cactus. It is interesting to note that the long period without drought influenced farmers to neglect the renovation of thei

Sugarcane is one of the most economical alternatives for off-season roughage feeding, which, whenever corrected, can become a feeding solution for animals with average production, even with the managerial difficulties of daily harvesting, regrowth handling, need for extra labor or specialized machinery, need to complete harvest within the same cycle, in addition to the risk of fire in the crop fields, all of which can be corrected. A correction alternative is sugarcane ensiling and nutritional e

Spittlebug, Mahanarva spectabilis (Hemiptera: Cercopidae) is capable to cause drastic losses in production and quality of pastures established with grasses. Currently, the use a grass resistant cultivar, to be obtained by means of constitutive antibiosis, is the best spittlebug controlling method. However, the time required for releasing a cultivar after detecting a spittlebug-resistant strain is relatively long. Allied to this, one should take into consideration that the adaptations of

The Cerrado is the second largest Brazilian biome and is considered one of the main biodiversity reserves on the planet that need to be conserved. For a rational and sustainable exploitation of this natural wealth, it is necessary to get to know it beforehand. A possible approach, from the point of view of the elaboration of products from Cerrado plants, is the use of aromatic species to obtain essential oils and extracts for application in the perfume and cosmetic industries. The main goal of t

From an economic point of view, Brazilian agribusiness has been recognized as modern, prosperous, profitable and competitive activity whose magnitude has established Brazil as a world agricultural power. The activity accounts for 26% of the gross domestic product, 42% of the volume of Brazilian exports, and 37% of the total number of jobs in the country. The finding from this scenario is that development in the country is strongly dependent on an increasing production of agricultural products
