Wake up and sell more coffee

Wake up and sell more coffee | Agronomic articles | Scoop.it
ON A hillside about an hour’s drive north of Nairobi, Kenya’s capital, is a visible demonstration of the difference between the miserable reality of smallholder farming in Africa and what it could be. On one side of the steep terraces stand verdant bushes, their stems heavy with plump coffee beans. A few feet away are sickly ones, their sparse leaves spotted with disease and streaked with yellow because of a lack of fertiliser.

International Year of Soils: Nutrients and soil biology | Ag Professional | Agronomic articles | Scoop.it
It is a tendency of some people to only think of plant nutrition in terms of how much fertilizer to add. This simplification may be understandable since a healthy crop reveals only the above ground plant; the roots that support the visible plant are seldom seen without further exploration.

Boosting global corn yields depends on improving nutrient balance -

Boosting global corn yields depends on improving nutrient balance - | Agronomic articles | Scoop.it

WEST LAFAYETTE, Ind. — Ensuring that corn absorbs the right balance of nitrogen, phosphorus and potassium is crucial to increasing global yields, a Purdue and Kansas State University study finds.

A review of data from more than 150 studies from the U.S. and other regions showed that high yields were linked to production systems in which corn plants took up key nutrients at specific ratios — nitrogen and phosphorus at a ratio of 5-to-1 and nitrogen and potassium at a ratio of 1-to-1. These nutrient uptake ratios were associated with high yields regardless of the region where the corn was grown

The use of biostimulants to reduce the impact of stress has been a valuable tool used by groundsmen and greenkeepers for many years. Stress can be biotic (e.g. disease, pest attack) or abiotic (e.g. cold, heat, drought) and, in most cases, the mode of action of biostimulants (such as seaweed extracts, humic acid, triazole fungicides, amino acids, potassium silicate) has remained elusive.

Understanding the historical probability of drought

Droughts can severely limit crop growth, causing yearly losses of around $8 billion in the United States. But it may be possible to minimize those losses if farmers can synchronize the growth of crops with periods of time when drought is less likely to occur. Researchers from Oklahoma State University are working to create a reliable “calendar” of seasonal drought patterns that could help farmers optimize crop production by avoiding days prone to drought.

2012 Crop Nutrient Deficiency Photo Contest Winners

2012 Crop Nutrient Deficiency Photo Contest Winners | Agronomic articles | Scoop.it

IPNI has announced the winners of the 2012 Crop Nutrient Deficiency Photo Contest. We are pleased to note that photo submissions were once again strong across all categories and many excellent photos were received from around the globe. Our judges were faced with many tough choices on deciding which entries would gain top honors. In the majority of cases, preference was given to those well-photographed entries that provided a good representation of the impact of the deficiency to the plant, adequate soil and/or plant tissue nutrient analyses information, and some details concerning current or historical fertilization at the site.

The Impact of Corn in 2013 | Corn content from Corn and Soybean Digest

Corn is more profitable per acre than soybeans, and more profitable than most cropping rotations would average. However, agronomic problems with continuous corn have pushed many farmers to consider a periodic change of crop.

Nitrogen Use Efficient Rice Demonstrates an Average Yield Increase of 30 Percent in Four Years of Field Trials

DAVIS, Calif. & PALMIRA, Colombia & NAIROBI, Kenya, Sep 09, 2015 (BUSINESS WIRE) -- Four years of field trials with a leading line of Nitrogen Use Efficient (NUE) rice have demonstrated an average 30 percent yield increase over conventional controls. These results were reported jointly today by Arcadia Biosciences, Inc., an agricultural technology company, the International Center for Tropical Agriculture (CIAT) and the African Agricultural Technology Foundation (AATF). CIAT has been testing the novel rice lines using Arcadia’s NUE trait at the center’s research fields in Colombia.

Around three-fourths of the world’s poorest people live in rural areas. The rural poor, and their very specific needs, must therefore be at the centre of any attempt to tackle global poverty and the issue of food security. But what are these very specific needs? Often they’re things that people in urban areas take for granted […]

Phosphorus starvation linked to symptoms of citrus disease Huanglongbing in new study

Phosphorus starvation linked to symptoms of citrus disease Huanglongbing in new study | Agronomic articles | Scoop.it

The citrus disease Huanglongbing (HLB), meaning “yellow shoot disease” in Chinese and also called citrus greening in English-speaking countries, is the most destructive disease threatening the citrus industry worldwide.  Powerful diagnostic tools and management strategies are desired to control it. A new study, ‘Small RNA profiling reveals phosphorus deficiency as a contributing factor in symptom expression for citrus Huanglongbing disease’,  published online today (Friday) in the journal Molecular Plant profiled small Ribonucleic Acids (sRNAs) from both diseased and healthy plants and found that some of these tiny molecules could potentially be developed into early diagnosis markers for HLB. More importantly, the study demonstrates that the diseased trees suffered from severe phosphorus (P) deficiency and that application of phosphorus solutions to the diseased trees significantly alleviated HLB symptoms and thus improved fruit yield in a three-year field trial in southwest Florida.

Breakthrough: How salt stops plant growth | Carnegie Institution for Science

Breakthrough: How salt stops plant growth | Carnegie Institution for Science | Agronomic articles | Scoop.it

Washington, D.C. —Until now it has not been clear how salt, a scourge to agriculture, halts the growth of the plant-root system. A team of researchers, led by the Carnegie Institution’s José Dinneny and Lina Duan, found that not all types of roots are equally inhibited. They discovered that an inner layer of tissue in the branching roots that anchor the plant is sensitive to salt and activates a stress hormone, which stops root growth. The study, published in the current issue of The Plant Cell, is a boon for understanding the stress response and for developing salt-resistant crops.
