  • Seeds of change in sub-Saharan Africa

    In the late 1900s, as per-acre grain yields moved to 3 metric tons per hectare in South and Southeast Asia and Latin America, 5 metric tons per hectare in China, and 10 metric tons per hectare in North America, Europe and Japan, there’s one place where production stagnated big time: sub-Saharan Africa, where loss of soil fertility on small farms trapped grain production at an unsustainable ...

  • Seeding rate and planting arrangement effects on growth and weed suppression of a legume-oat cover crop for organic vegetable systems

    Winter cover crops can add soil organic matter, improve nutrient cycling, and suppress weeds in organic vegetable systems. A 2-yr study was conducted on organic farms in Salinas and Hollister, CA, to evaluate the effect of seeding rate (SR) and planting arrangement on cover crop density, ground cover, and cover crop and weed dry matter (DM) with a mixed cover crop. The mix contained legumes (35% ...

  • Getting seed to smallholders needs a business approach

    A locally owned, alternative model of supplying affordable seed is working for Africa’s framers, says Joe DeVries. Smallholder farmers in Africa — mostly women — wage silent battles against the elements and other forces beyond their control to feed ...

  • Farm digesters for small dairies in Vermont

    THROUGH its award-winning Cow Power program, Central Vermont Public Service (CVPS), a Vermont utility headquartered in the city of Rutland, is helping dairy farmers diversify their incomes by turning manure into electricity. The farmers process manure in anaerobic digesters to generate power, which CVPS customers voluntarily pay a premium to purchase. In addition to income from electricity sales, ...

  • Comparison of certified and farm-saved seed on yield and quality characteristics of Canola

    Relatively high seed prices and low canola (Brassica napus L.) grain prices created a controversy over using farm-saved seed from hybrids. Agronomic implications of saving seed from a canola crop were investigated by planting certified seed and saved-seed of an open-pollinated and a hybrid canola cultivar at eight site-years in Saskatchewan and Alberta, Canada. In one series of experiments ...

  • How three U.S. mini-farms are sowing the seeds of global food security

    Tiny, biointensive operations show smallholder farmers from around the world how they can grow far more food than conventional approaches. Her face shaded by a wide-brimmed straw hat, Olawumi Benedict is cheerfully tending to her “little babies” — kale seedlings growing in shallow wooden flats until they’re hardy enough for transplantation into soil beds. Three miles over ...

  • Sample size and heterogeneity effects on the analysis of whole soybean seed using near infrared spectroscopy

    Soybean [Glycine max (L.) Merr.] breeders and physiologists are commonly interested in evaluating single plants for seed protein and oil concentration. Moreover, breeders tend to prefer nondestructive techniques so that soybean seed may be retained for variety development. Near infrared spectroscopy (NIRS) technology can be an inexpensive and convenient method for nondestructive analysis of seed; ...

  • Saddle up, soybean seed pigments: argonaute5 in spatially regulated silencing of Chalcone Synthase genes

    Most soybean seeds you see, whether in bins at the store, or in train cars as a commodity crop, have a yellow seed coat that may have only a tiny fleck of dark pigment at the hilum, where the seed attaches to the pod. The predominant yellow color results from silencing of chalcone synthase (CHS) genes by RNA interference (RNAi) due to the presence of I or ii alleles. The ii allele has an inverted ...

  • Does skip-row planting configuration improve cotton net return?

    Cotton (Gossypium hirsutum L.) growers want information about alternative planting configurations to reduce seed, technology, and other production costs. We evaluated the impact of solid and 2 x 1 skip-row configurations on net returns for cotton grown in 25-, 76-, and 102-cm rows based on yield and fiber quality data from an experiment in adjacent nonirrigated and irrigated fields at Milan, TN. ...

  • Hit the Spring Planting Target with Hydraulic Down Force

    Will Hutchinson enjoys a good challenge, especially when it comes to improving production on his row crop, wheat and alfalfa farm near Murfreesboro, Tennessee. So when he saw the opportunity to leverage Ag Leader’s Hydraulic Down Force system to prevent a common problem and improve his planting operations on acres where he plants cover crops, he jumped at the chance. Two years later, ...

  • Jojoba: A Potential Desert Oil Crop

    Jojoba (Simmondsia chinensis usually grows to a height of 1-2m and may reach heights of three meters or more under ideal growing conditions. S. chinensis has a normal life span of at least 100 years and may live more than 200 years. Pollination is via wind or insects. The fruit is a green capsule enclosing as many three seeds. When ripe (3-6 months after fertilization) the capsule splits and ...

  • Endosperm size diversity in domesticated, wild, and semiwild soybean

    Past literature documents that domesticated soybean, Glycine max (L.) Merr., has trivial to almost nonexistent galactomannan-containing endosperm in mature dormant seeds. Current preliminary observations confirm limited endosperm for many domesticated soybean accessions, but show that many others have markedly larger endosperm, as do all wild (G. soja Sieb. & Zucc.) and semiwild (G. gracilis ...

  • Cheap chemicals entice caterpillar-eating wasps to crops

    It may be a win-win situation: treating seeds with commercially available growth promoters before planting could have the added benefit of attracting parasitic wasps that feed on caterpillar pests, suggests a study. The protective effect of these cheap, commercially available chemicals, known as ‘plant strengtheners’, can help protect young ...

  • Variation in Adzuki Bean (vigna angularis) germplasm grown in China

    Adzuki bean [Vigna angularis (Willd.) Ohwi & Ohashi] is cultivated in a wide range of agroecological environments from north to south China. An understanding of the genetic variation for crop adaptation facilitates plant breeding. A core germplasm of 231 accessions (selected from a representative collection of 3908 Chinese landraces) was evaluated at diverse locations in China in 1998 to (i) ...

  • Local advice on managing blackgrass

    Blackgrass is a weed that troubles many, and controlling it is an increasing challenge, particularly with the small armoury of products available, and the growing issue with resistance. Paul Drinkwater, Crop Production Manager for Abbots Ripton Farming Company, explains how, in his 40 years of being in the Cambridgeshire area, the blackgrass problem has evolved. “My role sees me manage ...

  • Cost efficiency of cryopreservation as a long-term conservation method for coffee genetic resources

    Coffee (Coffea spp.) is one of the world's most valuable agricultural export commodities produced by small-scale farmers. Its germplasm, which holds useful traits for crop improvement, has traditionally been conserved in field genebanks, which presents many challenges for conservation. New techniques of in vitro and cryopreservation have been developed to improve the long-term conservation of ...

  • Sustainable Farm Practices for Rice Farming

    Rice is the third-largest crop production, after sugarcane and maize. The main producers of rice are the nations of China, India, Indonesia, Bangladesh, and Vietnam. Rice is a staple crop. More than half the people in the world, about 3.5 billion people, rely on its production. Not only is rice a key source of food but it is also good source of income for many smallholder farmers. The Challenges ...

  • Family farms can be competitive by focusing on conservation and stewardship

    While the U.S. Department of Agriculture (USDA) reports a 40 percent decline in U.S. cropland soil erosion rates from 1982 to 2007, recent trends appear to challenge this progress. Record prices for corn and soybeans have diverted acres out of conservation programs and encouraged intensive production on a wide scale. Tree lines are cleared and wet areas drained, turning 120-acre farms into ...

  • Drought Hits the Heartland of USA

    Worldwide, 2012 has been the year of drought. From the Midwest of the USA to the granaries of the Black Sea, from South Asia to the Sahel region of Africa, producers the world over have had to find ways to farm their land in the face of ravaging droughts or feeble monsoons. Both largeholders in food exporting regions and small-holders in poor countries have been hit by these droughts, which have ...
