Soybean seed yield and composition response to stand reduction at vegetative and reproductive stages

Soybean [Glycine max (L.) Merr.] producers across the United States are confronted with significant economic losses annually from hail. Plant injury and yield loss are associated with defoliation and node or stand loss due to bruising and breaking of plant stems from the hail. The correlation of yield loss and leaf defoliation is well defined; however, limited information exists relative to whole ...

No persistent changes in pasture vegetation or seed bank composition after fallowing

The practice of fallowing pastures during the growing season is intended to increase plant diversity and allow natural reseeding of forage grasses. Fallowing delivers these benefits in New Zealand, but has been adopted on rotationally stocked farms in the northeastern United States with little or no quantitative assessment. Allowing the pasture to remain ungrazed may allow weedy species to ...

Plant growth regulator effects on balancing vegetative and reproductive phases in alfalfa seed yield

The use of plant growth regulators (PGRs) has opened new prospects for increased seed production in grasses and legumes, but little information is available on the effects of PGRs on alfalfa (Medicago sativa L.) seed production. This study was conducted to evaluate the effects of applying chlormequat chloride (CCC) (2-chloroethyl-trimethyl-ammonium chloride) in combination with five PGRs ...

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% ...

FLAX SEED LEAFLET

Flaxseed (Linum usitatissiumum) also known as linseed, is thought to be one of the world’s oldest cultivated crops with evidence of cultivation dating back thousands of years. The crop is prized for its fibre and oil. The fibre, obtained from the stocks of the plant, is used to make fine linen and paper. The oil is used primarily for industrial purposes. The oil is probably best ...

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 ...

Soil seed bank composition in pastures of diverse mixtures of temperate forages

Seed banks may contribute useful or weedy species that fill gaps in pastures. In a previous study, pastures planted to complex mixtures of forages had a lesser proportion of weedy species in the aboveground vegetation. In this study, we relate changes in the species composition of the seed bank to changes in the aboveground vegetation. In August 2001, four mixtures [two, three, six, and nine ...

Main-stem node removal effect on soybean seed yield and composition

Hail injury to soybean [Glycine max L. (Merr.)] is common across the United States. Currently, U.S. hail adjusters use procedures that assume that yield reductions caused by stem cutoff and defoliation or defoliation without stem loss is similar during the vegetative development period. Our hypothesis was that seed yield will be affected by timing of node removal in vegetative soybean and that ...

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 ...

How `open source` seed producers from the U.S. to India are changing global food production

Around the world, plant breeders are resisting what they see as corporate control of the food supply by making seeds available for other breeders to use. Frank Morton has been breeding lettuce since the 1980s. His company offers 114 varieties, among them Outredgeous, which last year became the first plant that ...

Screening of coagulant proteins from plant material in southern India

Access to fresh water is limited due to the growing population and to provide safe drinking water is a global challenge. In this initial study, about a hundred different samples were screened for coagulation activity. Amongst the plants tested were fruits and vegetable pulps, leaves and seeds (like jackfruit, tamarind, papaya, orange, watermelon, pineapple, cucumber, green gram, peas, black ...

Impact of plant assemblages on nutrient removal in constructed wetlands

Four different mesocosm scale constructed wetlands - monoculture (Carexstipata), self–designed (passive) community, mixed planted monoculture–passive community and a non–vegetated control - were compared to assess the effects of plant community composition on the removal of inorganic nutrients from agricultural runoff (synthetic tile water). The mixed and self–designed systems consistently ...

Environmental analysis of the energy use of hemp – analysis of the comparative life cycle: diesel oil vs. hemp–diesel

Hemp (Cannabis Sativa L.) is a herbaceous crop with a potential production of 12 tons of dry matter per hectare and a seed output of 0.5–2 tons per hectare, depending on its handling. The agro-ecological aspects and the high yield of vegetable biomass from hemp farming are the factors that indicate a possible interest in this plant from the point of view of energy use, but in order to validate ...

Aboveground to root biomass ratios in pea and vetch after treatment with organic fertilizer

Some growth parameters of pea (cv. Pleven 4) and vetch (cv. Obrazets 666) after treatment with organic fertilizer were studied in a field trial carried out at the Institute of Forage Crops, Pleven, Bulgaria. Humustim as organic fertilizer was applied through presowing treatment of seeds, treatment during vegetation and combination between both, at different doses. Ratios of aboveground weight to ...

Economic Feasibility of Sustainable Non-Food Feedstock Based Biodiesel Production: Moringa

Development of Moringa as a biofuel crop has largely been underway in India, at CJP where scientists have been assessing new crops to support sustainable rural development. CJP is dedicated to the development of oil seed bearing trees - non-food multiple vegetable oil plantation and technologies in order to reduce dependence on fossil fuels, bring greater control and security of fuel supply and ...

Spatial pattern of variation in populations of Acacia nilotica in semi-arid environment

Variability among populations was analyzed in five provenances of Acacia nilotica from spatially variable habitats. Populations of A. nilotica developed in response to their habitat conditions. The level of variability was significantly high among the populations. Phenotypic variability was extremely high for leaf and stipular spine characteristics. The nature of morphological variability for ...

Increased inbreeding and inter-species gene flow in remnant populations of the rare Eucalyptus benthamii

Eucalyptus benthamii Maiden & Cambage is a forest tree of interest for conservation and plantation forestry. It is vulnerable to extinction, occurring on the alluvial floodplains of the Nepean River and its tributaries, south-west of Sydney, Australia. These floodplains were largely cleared of native vegetation for agriculture by the mid-1800s. Flooding of the Cox Valley for Sydneys water supply ...
