Sowing Guide for Different kind of Crops

Sowing Guide for Different kind of Crops

A crop is a plant or plant product that can be grown and harvested for profit or subsistence. By use, crops fall into six categories: food crops, feed crops, fiber crops, oil crops, ornamental crops, and industrial crops. Every crop farmer must be aware of the specie he/she wants to cultivate, the average number of seeds, the quantity for sowing per hectare and the crop density (Number of plants per hectare). This will help the farmer understand what his or her expectations are from the crops to be planted. Below…

Converting waste water from dairies to animal feed and aviation fuel

Microbes help turn Greek yogurt waste into fuel

Scientists have developed a bioprocess that enables conversion of acid whey, a dairy by-product, without the use of additional chemicals. Professor Lars Angenent from the Center of Applied Geosciences at the University of Tübingen and international colleagues used microbiome cultures similar to those in the human gut. The new bio-oil can be used in animal feed or, after further refinement, as a fuel for airplanes. The results of the study were published in Joule, a new premier journal from CellPress. Every liter of milk that goes into milk products, such…

Getting a better handle on methane emissions from livestock

Cattle, swine and poultry contribute a hefty portion to the average American’s diet, but raising all this livestock comes at a cost to the environment: The industry produces a lot of methane, a potent greenhouse gas. Just how much gas the animals release, however, is the subject of debate. Now, one group reports in ACS’ journal Environmental Science & Technology that a new approach could shed light on how accurate current data are. According to the U.S. Environmental Protection Agency, the livestock industry is the second-biggest methane emitter in the…

New Stress-Tolerant Rice Varieties Rolled Out for Africa by Rice Experts

The Africa-wide Rice Breeding Task Force, convened by the Africa Rice Center (AfricaRice), has recently nominated six varieties with improved tolerance to environmental stresses as ARICA, which stands for Africa Rice Varieties for Africa. “This is the second series of nominations since the ARICA brand was launched in 2013 to offer farmers a new generation of high-performing rice varieties for Africa,” said Dr. Moussa Sie, AfricaRice Senior Breeder and Breeding Task Force Coordinator. The ARICA varieties are selected through a rigorous multi-environment testing process including regional and national trials as…

BREADFRUIT’S ABILITY TO REPEL INSECTS – Study Confirms

BREADFRUIT’S ABILITY TO REPEL INSECTS – Study Confirms

Breadfruit, used as a folk remedy in pacific regions to control insects, is an effective mosquito repellent, U.S. Department of Agriculture (USDA) scientists have found. Agricultural Research Service (ARS) scientists and their collaborators at the University of British Columbia in Okanagan, Canada, identified three breadfruit compounds Capric, Undecanoic and Lauric acids that act as insect repellents. ARS is the chief intramural scientific research agency of USDA. In the study, chemist Charles Cantrell and his colleagues at the ARS Natural Products Utilization Research Unit (NPURU) in Oxford and the University of…

Fisheries given a solution to overharvesting

Fisheries given a solution to overharvesting

Consumer demand and inadequate scientific information has led to overharvesting, reducing fish species and fish stocks around the world. But University of Guelph researchers have identified a possible solution. They have developed a model that allows fisheries to net enough to meet rising consumer demand while ensuring adequate income and replenishment of natural stocks. The research was published in Proceedings of the National Academy of Sciences. “We know fish are getting rarer,” said John Fryxell, a U of G integrative biology professor and lead author of the paper. Many commercial…
