Genetics not enough to increase wheat production
The deep gene pool that has allowed wheat to achieve ever increasing gains in yield may be draining. Crop scientists estimate that 50% of the gain in wheat production over the past century has been due to breeding. According to a new study, however, that improvement has been slowing since the late 1980s, with little chance that future increases in yield can be met by breeding efforts alone. The ...

Independent variety trials show productivity of wheat varieties continues to increase
Nowhere in the world is the average grain yield as high as in the Netherlands, where it is over ten tonnes per hectare. Research by Wageningen UR shows that the introduction of new varieties has caused yields to increase by approximately 8 to 10 per cent per decade. Converted to a hectare of winter wheat, this represents an increase of 800 to 1,000 kilograms; a huge achievement for breeders of ...

Can one-time tillage improve no-till?
A one-time tillage has no adverse effects on yield or soil properties on no-till land, according to field research conducted at the University of Nebraska-Lincoln. Although tillage is another expense for farmers and generally increases the risk of soil erosion, a one-time tillage may be performed to correct some problem, such as a perennial weed problem. The feasibility study was conducted for ...

Salt-tolerant wheat a breakthrough for better yields
Australian scientists have successfully carried out field trials of a salt-tolerant durum wheat, boosting grain yield by 25 per cent in salty soils. Durum is one of the most widely grown cereals in the world, but in saline soils it is vulnerable to salt build-up in the leaves, which can hinder growth and reduce yields, threatening food security. The researchers at the University of Adelaide and ...

Improving wheat yields for global food security
With the world’s population set to reach 8.9 billion by 2050, CSIRO scientists are hunting down and exploiting a number of wheat’s key genetic traits in a bid to substantially boost its grain yield. The rate of wheat-yield improvement achievable through conventional plant breeding and genetic engineering alone is not fast enough to compete with a rapidly growing global ...

In-crop nitrogen key to summer sorghum yields
With the summer cropping season on our doorstep, growers are weighing up their planting options against the market, seasonal conditions and gross margin calculations. For many the summer cropping rotation will include sorghum and maximising crop yield and profitability will be a key driver of all pre-plant and in-crop agronomic decisions. Recent research funded by the GRDC, Queensland Alliance ...

Late-Planted Corn Can Still Reap Strong Yields
Growers worried about delayed planting for corn, take heart – late-planted corn sometimes has reaped better yields than early planted corn, says an agronomist in the College of Food, Agricultural, and Environmental Sciences at The Ohio State University. It’s true that the optimal time to get corn planted in southern Ohio is between April 10 and May 10 and in northern Ohio between ...

Iron deficiency in soil threatens soybean production
An expansion of soybean production into areas where soybean has seldom, if ever, been grown can be problematic for some farmers. Soils having high pH values and large amounts of calcium and/or magnesium carbonate are notoriously iron deficient. Iron deficient soils in the North Central United States are estimated to reduce soy bean production by 12.5 million bushels every year. John Wiersma, a ...

A little nitrogen can go a long way
Varying the rate of crop production inputs such as fertilizer and seed makes intuitive sense, as farmers have long observed differences in crop yield in various areas of a single field. The availability of spatial yield information from combines equipped with yield monitors has provided a good resource for improved management. So, optimizing inputs to match yield potential of different areas ...

Crop performance matters when evaluating GHGs
Measuring the emission of greenhouse gases from croplands should take into account the crops themselves. That’s the conclusion of a study in the September-October issue of the Journal of Environmental Quality, which examined the impact of farm practices such as tillage on the greenhouse gas, nitrous oxide (N2O). Expressing emissions per unit of crop yield rather than on a more conventional ...

Straw covering on soil can increase crop yields and improve the efficiency of water use
Straw from previous harvests can be used to help increase crop yields and improve the efficiency of water use in arid regions, finds a new study from China. By testing different techniques to improve water efficiency, the researchers found that the most effective method involved using straw to cover the soil when growing maize and wheat together in the same growing season. In north-western ...

High-yield crops have curbed agricultural land expansion, but care needed to avoid negative biodiversity effects
The widespread use of higher-yielding improved varieties of crops as part of the Green Revolution’ has averted the conversion of between 18 to 27 million hectares of forests, woodlands and pastures in the period 1965 to 2004, according to a recent study. However, its authors caution that the relationship between these crops and land use change is complex, and good governance is needed to ...

Compost made by worms from livestock manure yields benefits when applied to maize
Vermicomposting livestock manure with maize can increase agricultural benefit by 304%, shows a new study. The combination of increased crop yield and the additional earthworms produced as a result of the process led to a substantial increase in output compared to a traditional composting system. As intensive agriculture and livestock production both increase, unique problems emerge. Heavy use of ...

Rice Farmers in China use Less Fertilizer, Increase Yield
“Rice farmers can decrease their nitrogen fertilizer and pesticide use by around 20%, and increase their yield by 10% by using the ‘three controls technology’ (3CT),” says Dr. Xuhua Zhong, crop physiologist at the Rice Research Institute of the Guangdong Academy of Agricultural Sciences (GDRRI). The meaning of “three controls” is controlling the amount of ...

Straw residue helps keep nitrogen on the farm
Scientists are exploring ways to reduce non-point pollution from agriculture. A new study finds that using straw residue in conjunction with legume cover crops reduces leaching of nitrogen into waterways, but may lower economic return. Agriculture is the largest source of nitrogen non-point pollution to waterways in the United States, flowing into streams and rivers via erosion from farmlands, ...
