Variable-load unmanned aerial vehicles (UAVs) are key tools in smart agriculture, particularly playing a vital role in the prevention and control of crop pests and diseases. Equipped with pesticide spraying equipment, these quadrotor UAVs offer advantages such as high operating speed, low risk of chemical drift, and improved crop coverage, making them widely used in agricultural plant protection.
Eggs and poultry provide important sources of protein globally, driving a major industry with large economic impacts. Challenges to hatchery operations include embryo mortality, fertility, sex determination, and eggshell characteristics. These features have a substantial impact on production, but they are difficult and time-consuming to estimate. A University of Illinois Urbana-Champaign research team has conducted multiple studies using near infrared (NIR) and hyperspectral imagery (HSI) to evaluate chicken eggs, potentially leading to more efficient, safe, and humane production methods. They discuss their findings in a series of publications.
Climate extremes are adversely affecting cacao production. A recent study by Hasanuddin University highlights the potential of multistrata shade structures in addressing these challenges. Researchers show how a mix of shade trees—such as coconut, banana, and Gliricidia sepium—can help cacao plants grow better and become more resilient. These trees can improve soil fertility and help cacao plants cope with environmental variability—offering a pathway toward more resilient and sustainable smallholder agriculture.
How food is shared inside ant colonies has long been invisible in real time. Researchers in Japan have now used a highly sensitive radioactive imaging technique to watch food move from ant to ant, minute by minute. The method reveals unexpected patterns in how resources spread through a group and could help scientists detect early warning signs of stress or imbalance in insect societies, crucial to ecosystems and agriculture.
Cotton genome editing, especially in elite varieties, has proven difficult. Now, in a study published in The Crop Journal, researchers from China have successfully demonstrated CRISPR/Cas genome editing in nonregenerative cotton via sexual hybridization. This work opens up a novel technical avenue for the genetic improvement of elite cotton varieties that are recalcitrant to tissue culture, advancing agriculture and biotechnology.
