The worst drought in five years has pushed 900,000 people in Sri Lanka into "acute food insecurity", the World Food Programme (WFP) says.

Crop management practices have a significant impact on greenhouse gas (GHG) emission rates, where methane (CH4) and nitrous oxide (N2O) emissions from rice paddy fields are in trade-off association. A field study for two consecutive years (2013 and 2014) was conducted to continuously measure CH4 and N2O emissions from rice paddies under various agricultural management schedules like water regimes (irrigated and rainfed), transplanting dates and nutritional amendments (synthetic fertilizer with N as ammonium sulphate, P and K according to recommended dose, and vermicompost).

Scientists at the University of Ilorin and their counterparts at Afe Babalola University, Ado-Ekiti (ABUAD), are finalising arrangements to develop an improved rice variety with medicinal potential

The Federal government has stated that because of the conscientious efforts of the President Muhammdu Buhari-led administration, the country has just achieved the record of being the second largest

Recent comparative product testing by city-based Consumer Education and Research Centre (CERC), found traces of pesticides and heavy metals in six supposedly-organic brands of rice.

The current drought will cut rice production by half piling more pressure on the already worsening food crisis in the country.

While outlining strategies to increase availability of pulses at affordable prices, it is argued that increasing domestic production of pulses is the only option. Access to one or two protective irrigation sources during the growing season can lead to sizeable increases in pulse production. The har khet ko paani initiative should give priority to pulse-producing areas. The minimum support price, without procurement, helps traders more than farmers because it acts as a focal point for tacit collusion among traders.

Attempts to measure the impacts of climate change on agriculture must invariably rely on models that translate changes in climate to changes in agricultural outcomes. This need for models exists even when assessing the impacts of climate trends that have already occurred, since simultaneous changes in other factors that affect agriculture, such as technologies and government policies, preclude direct observations of impacts. Over several decades, many approaches to developing these models have evolved, with most falling into one of two camps.

Existing theory, empirical, clinical and field research all predict that reducing the virulence of individuals within a pathogen population will reduce the overall virulence, rendering disease less severe. Here, we show that this seemingly successful disease management strategy can fail with devastating consequences for infected hosts. We deploy cooperation theory and a novel synthetic system involving the rice blast fungus Magnaporthe oryzae. In vivo infections of rice demonstrate that M.

As the effects of climate change set in, and population and income growth exert increasing pressure on natural resources, food security is becoming a pressing challenge for countries worldwide.
