  • Tiller contribution to spring wheat yield under varying seeding and nitrogen management

    Hard red spring wheat (HRSW) (Triticum aestivum L.) grain yield is comprised of the combined production of the main stem and tiller spikes. Experiments were conducted under dryland (Casselton, ND) and irrigated (Carrington, ND) conditions from 2003 to 2005 to determine tiller development and the relative contribution of main and tiller wheat spikes to final grain yield under varying cultivar, ...

  • Effect of defoliation severity on regrowth and nutritive value of perennial ryegrass dominant swards

    The height or mass to which swards are defoliated can potentially affect regrowth. A field study was undertaken to determine the response of perennial ryegrass (Lolium perenne L.) dominant swards to defoliation severity over repeated defoliations during a period of low water-soluble carbohydrate (WSC) accumulation (late spring to mid-autumn due to active leaf growth and relatively high ...

  • Genetic improvement of Sorghum as a biofuel feedstock: II. QTL for stem and leaf structural carbohydrates

    Digestion and fermentation of lignocellulosic biomass (i.e., structural carbohydrates) are predicted to deliver higher yields of energy per hectare than sugar and starch (nonstructural carbohydrates), yet little research on genetic variation in crop feedstock biomass traits has been conducted. We investigated the genetic basis of leaf and stem biomass yield and composition in a population derived ...

  • Nutrient acquisition and yield response of Barley exposed to salt stress under different levels of potassium nutrition

    Abstract: A greenhouse experiment was carried out in 2002 at Jordan University of Science and Technology, Agricultural Experiment Station to examine the effect of potassium fertilization on the response of barley (Hordeum vullgare L.) to different soil salinity levels. Five levels of potassium (0, 0.2, 0.4, 0.6, and 0.8 g K per pot as KCl) and two salt levels (0.75 and 13 ds/m) were ...

  • 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 ...

  • Giant black-grass requires lock stock approach

    Nigel Riches, Arable Technical Specialist for Certis, explains what he’s been seeing in the field. “Black-grass is a problem that in the past has generally been confined to the main arable areas, in the east of the country. “But increasingly we’re seeing this pernicious weed spreading further west each season. Where previously black-grass has not been a big issue in the ...

  • Seeding rate and nitrogen management effects on spring wheat yield and yield components

    Seeding rate, N level, and N application timing are key management factors for spring wheat (Triticum aestivum L.) production in North Dakota. Experiments were conducted under dryland (Casselton, ND) and irrigated (Carrington, ND) conditions in 2003 to 2005 to determine the optimum combination of seeding rate and N management to maximize yield of hard red spring wheat (HRSW). Treatments consisted ...

  • Winter wheat and maize response to urea ammonium nitrate and a new urea formaldehyde polymer fertilizer

    Slow release N fertilizers have potential to improve yield and nitrogen use efficiency (NUE) in winter wheat (Triticum aestivum L.) and maize (Zea mays L.). A slow release urea formaldehyde polymer (UFP) was compared with aqueous urea ammonium nitrate (UAN) [(NH2)2CO, NH4NO3] during a 2-yr field experiment in North Carolina. Crops were grown on Candor (sandy, siliceous, thermic Grossarenic ...

  • Conservation: It’s the right thing to do

    A fable of six blind men and an elephant originated centuries ago somewhere on the Indian continent. In it the blind men try to identify an elephant by touching only one part. According to the fable each man came to a different conclusion as to what the elephant was. The parable illustrates that though opinions may vary, there’s some truth to be found in all of them. That’s the way it ...
