  • Soybean seed yield response to planting date and seeding rate in the upper Midwest

    Planting date and seeding rate are agronomic decisions that producers can use to maximize soybean [Glycine max (L) Merr.] seed yield and economic return. Current information on the response to planting date and seeding rate may underestimate the yield penalty for delayed planting in northern climates and overestimate the seeding rate required to optimize yield. The objective was to determine the ...

  • Salinity effects on seed germination and plant growth of guar

    The potential of guar [Cyamopsis tetragonoloba (L.) Taub.] as a feasible crop for saline soils was tested in this study by evaluating seed germination of 42 accessions of guar in sodium chloride (NaCl) solution. The seeds were germinated in 200 mM NaCl or double-distilled water (control). There were significant differences in salt tolerance among the accessions tested. Percentages of seeds ...

  • Grow to Order and Seed Collection

    Local provenance planting is important to help restore our natural habitats and retain the genetic integrity of plant populations and is strongly recommended for projects within or near environmentally sensitive areas. Forward planning is essential when undertaking local provenance seed collection as there are seasonal constraints such as seed maturation time, finding seed donor sites and gaining ...

  • Effect of seeding rate and planting arrangement on rye cover crop and weed growth

    Weed growth in winter cover crops in warm climates may contribute to weed management costs in subsequent crops. A 2-yr experiment was conducted on an organic vegetable farm in Salinas, California, to determine the impact of seeding rate and planting arrangement on rye (Secale cereale L. ‘Merced’) cover crop growth and weed suppression. Each year, rye was planted in October at three rates (90, ...

  • Planting date and seed treatment effects on soybean in the northeastern United States

    Soybean [Glycine max (L.) Merr.] production is limited in the northeastern United States so research on optimum planting date is scarce. Soybean production in this region may increase because of biodiesel demand so we initiated a 2-yr study in New York that compared soybean planting dates with and without seed-applied fungicide/insecticide treatments. Soybean planted in mid- compared with late ...

  • 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 ...

  • Sowing the seeds of smarter transport policy

    Did we miss something? Last year, the European Commission didn’t propose a single new legislative measure to clean up transport. To be fair, it has been spending most of its time worrying about the future of the Eurozone. As a result, for T&E this was the sort of year where seeds for smarter transport policy were sown. We’re optimistic that next year could bring a decent crop of ...

  • How biotechnology is changing the structure of the seed industry

    The seed industry has been in a state of restructuring for many years now. New firms have entered the industry and old players have merged. Firms from various backgrounds now compete in supplying seed to agriculture and horticulture traditional seed companies, new biotechnology firms, agrochemical companies, food processors and wholesalers/retailers. As biotechnology enables the enhancement of ...

  • Feasibility of seed production from nonflowering orchardgrass

    Nonflowering or sparse flowering orchardgrass (Dactylis glomerata L.) would greatly simplify management of intensive rotational grazing systems. Our objective was to quantify seed production on nonflowering orchardgrass clones selected in cold-winter climates, but grown for seed in mild-winter climates. We evaluated 98 orchardgrass clones for seed production traits at four locations. Most plants ...

  • Effect of row spacing and seeding rate on soybean yield

    Soybean [Glycine max (L.) Merr.] yield response to narrow row spacing has been consistently positive in the upper Midwest and new split-row planters have made narrow row soybean production feasible, yet adoption has been slow in Iowa. Wide (76-cm) and narrow (38-cm) row spacing and four seeding rates (185,000; 309,000; 432 000; and 556,000 seeds ha–1) were evaluated at three locations during ...

  • The value of seed harboured in Mediterranean temporary ponds

    Temporary ponds and their varying water levels provide the conditions for valuable wildlife habitat. A study in Crete, conducted under the LIFE-Nature project1 Actions for the Conservation of Mediterranean Temporary Ponds in Crete, has demonstrated these ponds contain varied collections of seeds and that these ‘seed banks’ could play an important role in vegetation recovery after ...

  • Predicting outcrossing in maize hybrid seed production

    Controlling pollination of the female inbred is critical to achieve maximum kernel set and high levels of genetic purity in maize (Zea mays L.) hybrid seed production. Although kernel set associated with inbred flowering dynamics is fairly predictable, it has not been possible to predict the level of outcrossing resulting from adventitious pollen entering the seed field. Our objective was to ...

  • 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 ...

  • Bumble bee pollinators in red clover seed production

    Bumble bees pollinate red clover (Trifolium pratense L.) but impact on seed production depends on the species, abundance, and synchrony with bloom. The objectives of the current study were to examine pollination by a native bumble bee, Bombus vosnesenskii (Radoszkowski), determine the bumble bee fauna associated with red clover in Oregon, and assess if seed set is limiting. In a cage study, ...
