The prices of wheat, rice, chicken and garlic are lower in Pakistan than in India, Bangladesh and Sri Lanka, authorities said.
The National Price Monitoring Committee said food prices in Pakistan were comparatively lower than other countries in the region, reported Dawn.
The panel has not ruled out the possibility of importing items of daily use from neighbouring countries due to the extensive damage to crops in rain- and flood-affected areas of Sindh province where over six million acres of land has been inundated and seven million people have been impacted.

New cacao types with unique flavors that are distinctly Peruvian have been identified by U.S. Department of Agriculture (USDA) scientists. These new flavors could one day be marketed like wine, by geographical provenance.
Agricultural Research Service (ARS) scientists at the agency's Sustainable Perennial Crops Laboratory (SPCL) and Systematic Mycology and Microbiology Laboratory (SMML), both in Beltsville, Md., and Peruvian collaborators found these new cacao plants during collection expeditions in 2008 and 2009 in the Amazon Basin of Peru.
ARS is USDA's principal intramural scientific research agency, and this research supports the USDA priority of promoting international food security.

Evolutionary traps, invasive yellow starthistle’s favorable response to carbon dioxide and plant breeding for harmony between agriculture and the environment Evolutionary traps in human-dominated landscapes
A study published in the September issue of Ecology looks at how human activities can diminish the usefulness of an ornamental trait, such as colorful feathers, as a signal of fitness. Cardinals, for example, need carotenoids in their diet to produce their red plumage; brilliant red plumage can signal an individual's health and fitness.

The biotech industry boosted farming across the globe to the tune of almost $65 billion during the period 1996 to 2009, according to the latest analysis published in the International Journal of Biotechnology. $65 billion is the increase in net farm income, the farm level benefit after paying for the seed and its biotech traits. The study's authors estimate that almost half of that was derived by farmers in the developing world.

Production of crop milk, a secretion from the crops of parent birds, is rare among birds and, apart from pigeons, is only found in flamingos and male emperor penguins. Essential for the growth and development of the young pigeon squab, pigeon 'milk' is produced by both parents from fluid-filled cells lining the crop that are rich in fat and protein.
Research published in BioMed Central's open access journal BMC Genomics uses new technology to study the genes and proteins involved in pigeon 'milk' production and shows that pigeon 'milk' contains antioxidants and immune-enhancing proteins.

A commercial enzyme could reduce overall costs linked with producing ethanol from grain, and also reduce associated emissions of greenhouse gases, according to a study by U.S. Department of Agriculture (USDA) scientists and colleagues.
The researchers found that the enzyme helps extract water from an ethanol byproduct used to make dried distillers grains with solubles (DDGS), which can be used as feed supplements for cattle, swine and poultry. This could significantly reduce the amount of electricity, natural gas, energy and water needed for production of grain ethanol and its marketable byproducts. Results from this study were published in the scientific journal Industrial Biotechnology.

Restoring and preserving dryland forests and planting more trees to provide food, fodder and fertilizer on small farms are critical steps toward preventing the recurrence of the famine now threatening millions of people in the Horn of Africa, according to forestry experts from the CGIAR Consortium.
Across the Horn, drought-induced famine has claimed tens of thousands of lives and swelled refugee camps in Kenya, Ethiopia and elsewhere, with millions of starving people -- many of them children. Bearing the brunt of the crisis is Somalia, which not coincidentally is also a country that has lost a significant amount of its forests.

Paddy arrivals at the Karnal grain market terminal have been low so far as the crop is not matured enough for harvest in all growing areas.
Arrivals may gather pace within next 10 days, while arrivals of all paddy varieties may start around mid-October, said Mr Satpal Singh, a commission agent. Quality of the stock is good and moisture level is also according to the norms, he added.
The market is moving range-bound but within a positive territory, said market sources. Demand for non-basmati varieties and brokens of both aromatic and non basmati varieties is good, supporting the market and prices may rule firm for next few days.

For decades, scientists have believed that a relationship exists between how much biomass plant species produce and how many species can coexist.
This idea comes from a 1970s study that showed as plant biomass produced - called plant productivity - in a system increased, so did the number of plant species - referred to as plant richness - to a point. After that point, the number of plant species is thought to decline.
When plotted on a graph, the resulting line forms a hump shape, with maximum species richness occurring at the point of intermediate productivity.

In an intriguing original look at the history of the first Americans, a new study finds evidence that the north-south orientation of the American continents slowed the spread of populations and technology, compared to the east-west axis of Eurasia. The research, published in the American Journal of Physical Anthropology, is part of a special section which explores who the first Americans were and how they were able to settle in the last great unexplored habitat.

In a new study, Chen-Yu Zhang's group at Nanjing University present a rather striking finding: that plant miRNAs could make into the host blood and tissues via the route of food intake. Moreover, once inside the host, they can elicit functions by regulating host "target" genes and thus regulate host physiology.

When wireworms feast on potatoes, the results aren't pretty: The spuds' surfaces are left punctured, pitted and unappealing. For the past few years, U.S. Department of Agriculture (USDA) scientists and their colleagues have sought a solution in the form of spuds with genetic resistance to the worms, with special attention focused on two wild potatoes from Chile and Bolivia: Solanum berthaultii and S. etuberosum.
Previous studies showed that the wild potatoes resisted Colorado potato beetles and green peach aphids, two very different pests. Given this broadspread resistance, the researchers decided to see how the spuds fared against wireworms, which are the click beetle's larval stage.

Durum wheat is a valuable cereal crop widely used for human consumption in the United States, Canada, and several European countries. Scab or Fusarium head blight is one of the crop’s most serious diseases, reducing its grain yield and quality. Current durum cultivars don’t have resistance to this widespread disease.
While working on the Durum Germplasm Enhancement Project (DGE), Dr. Prem Jauhar and staff at the USDA-ARS Northern Crop Research Laboratory, Fargo, ND discovered that a diploid wheatgrass contains the genes needed for scab resistance.

Modifying soybean seed to increase phosphorus content can improve animal nutrition and reduce feed costs and nutrient pollution. However, further research is needed to commercialize this valuable technology. Knowledge of soybean and other crops such as maize suggest that reducing phytate, the principle storage form of phosphorus in plant tissue, in seeds reduces seed germination and emergence of seedlings in the field. In soybean, however, researchers debate whether this problem exists, and suggest that other factors may be the cause.

Fungi found in the leaves and trunks of wild Peruvian cacao trees offer the potential for biological control of cacao diseases such as witches' broom disease, according to U.S. Department of Agriculture (USDA) scientists. Several of the fungal species were previously unknown to science.
Agricultural Research Service (ARS) researchers at the agency's Sustainable Perennial Crops Laboratory (SPCL) and Systematic Mycology and Microbiology Laboratory (SMML) in Beltsville, Md., and Peruvian collaborators conducted cacao collection expeditions in 2008 and 2009 through the Amazon Basin of Peru.
