Ancient Maize Discovery in Brazil Offers New Clues About Crop Domestication
Publicado em 12 de dezembro de 2024
Scientists have unearthed a groundbreaking discovery in the Peruaçu Valley caves of Minas Gerais, Brazil: ancient specimens of partially domesticated maize (Zea mays) with traits resembling its ancestral form, suggesting South America had a pivotal role in shaping one of the world’s most important crops.
These findings challenge the long-held belief that maize domestication occurred exclusively in Mexico. According to a press release, this breakthrough adds a new dimension to [...]

Water overuse in Brazil's MATOPIBA region could mean failure to meet up to 40% of local demand for crop irrigation
Publicado em 05 novembro 2024Considered one of the fastest-growing agricultural frontiers in Brazil, and the area with the highest greenhouse gas emissions in the Cerrado, Brazil's savanna-type biome, the region known as MATOPIBA, risks facing water shortages in the years ahead. Water overuse may mean that between 30% and 40% of demand for crop irrigation cannot be met in the period 2025-40. MATOPIBA is a portmanteau of the names of four states—Maranhão, Tocantins, Piauí, and Bahia (all but [...]ver notícia -
Digital technologies help increase productivity and reduce agricultural impacts
Publicado em 12 fevereiro 2024Growers of peanuts (Arachis hypogaea L.), potatoes (Solanum tuberosum) and sweet potatoes (Ipomoea batatas) face the challenge of estimating the best time to harvest and the quality and yield of their crops. This is because these crops are subterranean, meaning the fruit develops below ground and is not visible until harvest time. "To harvest peanuts, 70% of the pods must be ripe, and to check this, you have to pull the plants out of the ground and make a visual assessment. This [...]ver notícia -
UK - Growers need fresh approach to tackle increasing insect resistant to biopesticides
Publicado emInsect pests that attack crops have extraordinary powers to develop resistance to greener pesticides, and a new way to manage resistance risks is needed, according to an analysis by the University of Stirling academics. For more than 70 years, agriculture’s response to pesticide resistance has been to seek new pesticides in an endless race to keep up with evolving pests. Researchers now propose a new way to step off this treadmill as farmers embrace the ongoing green revolution in [...]ver notícia
