The importance of Leaf Area Index (LAI) in environmental and crop research
Leaf Area Index (LAI), which is used as a measure in hundreds of studies on forests, crops, climate and the environment, is calculated as half the area of all leaves per unit area of ground. It is measured as the leaf area (m2 ) per ground area (m–2) and is unit-less. So, a plant with a LAI of 2 has an amount of leaves that can cover a given area two times. LAI is calculated for a plant or ...

The Ins and Outs of Cattle Nutrition
They say, “You are what you eat.” What goes in and out of our bodies is obviously important for our general health and maintenance. Well, the same holds true for our cattle as well, but with one main difference: Where we only have one stomach to worry about, they have four! Cattle are animals technically classified as ruminants, a distinction that includes sheep, goats, and deer. ...

Biofuel, Corn, And Sorghum Farmers Challenge Lowered RFS Volumes
On January 8, 2016, seven biofuel and agriculture groups requested the U.S. Court of Appeals for the D.C. Circuit to review the Renewable Fuel Standards (RFS) for 2014, 2015, and 2016. The Petition was filed by Biotechnology Innovation Organization, Americans for Clean Energy, American Coalition for Ethanol, Growth Energy, National Corn Growers Association, National Sorghum Producers, and the ...

Can genetic engineering help quench crops’ thirst?
Researchers around the world are exploring how GMO technology might boost food production under hot, dry conditions. Roger Deal is trying to figure out how plants remember drought. An assistant professor of biochemistry and genetics at Emory University, Deal says most plants have a kind of memory for stress. When experiencing water shortage, for example, plants close the holes in their leaves, ...

A win for farmers and the environment
Is it possible to reduce pesticide use without compromising crop yields? Yes — and then some, according to a new study published in the journal Insects. Researchers at the University of Essex in the United Kingdom measured pesticide use and crop yield at 85 project sites in 24 Asian and African countries practicing integrated pest management — an agronomic approach that taps ...

Better photosynthesis for a better world?
There’s no question that plants are better than most other life forms at converting carbon dioxide and sunlight into the sugars that form the basis of our global food web — and eventually, humans’ entire food supply. But fact of the matter is, with conversion rates hovering around 2 percent for our best crop fields, they’re by no means great. Even a slight increase in the ...

Could traditional plants hold the secret to saving crops from pests?
Researchers build on age-old practices to reduce food loss in Africa Without any effort at all, Hawa Saidi Ibura crushes dried beans, one at a time, between her fingers outside her home in Endagaw, a village in northern Tanzania. She’s holding a basket of a type of red bean eaten all over East Africa, but these beans are skeletons of what they once were. She harvested them from her farm ...

Comparative attributional LCA of annual and perennial ligno‐cellulosic feedstocks production, under Mediterranean climate, for bio‐refinery framework
Annual fiber sorghum (FS) and perennial giant reed (GR) cultivated in the Mediterranean area, appear of interest due to their high productivity under drought conditions and the potential use as lignocellulosic feedstock for biorefinery purpose. This study compares the environmental constraints related to FS and GR produced in an experimental farms (Campania region), by means of an ...

Estimation of possible energy contributions of crop residues in Nigeria
This study applied a simple methodology to evaluate energy contribution of selected crop residues to the possible replacement of conventional sources of energy and their specific technologies based on Nigerian situations. Using this methodology, energy content, replacement energy value, energy cost and energy return of crop residue (kJ per kg dry matter) were considered. The cost estimates of ...

Biofuel scenarios in a water perspective: The global blue and green water footprint of road transport in 2030
Concerns over energy security and climate change stimulate developments towards renewable energy. Transport is expected to switch from fossil fuel use to the use of fuel mixtures with a larger fraction of biofuels, e.g. bio-ethanol and biodiesel. Growing biomass for biofuels requires water, a scarce resource. Existing scenarios on freshwater use usually consider changes in food and livestock ...

How to create resilient agriculture
Durable food security and agricultural growth depend on development strategies with resilience built in from the start, says Gordon Conway. Economic growth with resilience to environmental threats will be central to the agenda of the UN Conference on Sustainable Development (Rio+20) in June this year, which aims to map out a pathway of sustainable development for the planet. The 'zero draft', ...

Solid-state fermentation for production of gibberellic acid using agricultural residues
Solid-State Fermentation (SSF) was employed using agricultural residues, viz. pigeon pea pod (Cajanus cajan), corncobs (Zea mays), sorghum straw (Sorghum vulgare) and pea pod (Pisum sativum) for the production of gibberellic acid (GA3) using Fusarium proliferatum NCIM1105. Studies revealed that these agricultural residues have supported excellent growth of the fungi in modified medium and gave ...

Economic partnership agreements, common external tariff and prospects for staple food items in Nigeria
This paper looks into the potential impacts of the proposed Economic Partnership Agreement (EPA) between African, Caribbean and Pacific countries and the European Union (EU) on agriculture and food production in Nigeria. Using a partial equilibrium analysis, it assesses possible changes in production arising from the implementation of a Common External Tariff (CET) and/or EPA on three crops ...

Skip-row and plant population effects on sorghum grain yield
In environments with limited rainfall, skip-row configuration (planting one or a group of rows alternated with rows not planted) under rainfed conditions may increase yield of grain sorghum [Sorghum bicolor (L.) Moench] due to conservation of soil water between widely-spaced crop rows that is not accessed until late in the growing season. A field study was conducted over 10 site-years in Nebraska ...

Irrigation frequency effects on growth and ethanol yield in sweet Sorghum
With the increasing costs of fossil fuels, new methods of generating renewable fuels need to be researched and developed. This study was undertaken to assess the effects of irrigation frequency on crop growth and ethanol yield of sweet sorghum [Sorghum bicolor (L.) Moench]. Nine combinations of pre- and postanthesis irrigation frequencies triggered by 35, 50, or 65% depletion of plant-available ...

Dryland performance of sweet sorghum and grain crops for biofuel in Nebraska
Sweet sorghum [SS; Sorghum bicolor (L.) Moench] is a potential biofuel crop for the Great Plains. Sweet sorghum was compared with corn [Zea mays (L.)] and grain sorghum for potential ethanol yield, energy use efficiency, and greenhouse gas (GHG) emissions at seven dryland site-years in Nebraska. Seasonal rainfall ranged from approximately 340 to 660 mm. Soils were deep with medium texture at all ...

Wheat and sorghum residue removal for expanded uses increases sediment and nutrient loss in runoff
Received for publication January 16, 2009. Crop residue removal for expanded uses such as feedstocks for cellulosic ethanol production may increase loss of sediment and nutrients in runoff. We assessed on-farm impacts of variable rates of residue removal from no-till winter wheat (Triticum aestivum L.) and plow till grain sorghum [Sorghum bicolor (L.) Moench] on sediment, soil organic carbon ...
