Fine root distributions in oilseed and pulse crops
Fine roots are of great importance in the uptake of water and nutrients from, and input of, carbon to the soil. This study determined the proportion of extra fine (0.4 mm contributed a small proportion to the total. For pulses (Cicer arietinum L. chickpea, Pisum sativum L. dry pea, and Lens culinaris Medik. lentil), the proportion of roots in the 0- to 0.2-mm diameter was much smaller than that ...

Inheritance of susceptibility to ethametsulfuron herbicide muster in summer turnip rape (Brassica rapa L.)
The Brassica oilseed crops, Brassica rapa L., B. napus L., and B. juncea (L.) Czern. & Coss., carry the inherent property of tolerance to the acetolactate synthase–inhibiting herbicide ethametsulfuron. However, a self-compatible line of B. rapa subsp. oleifera (DC.) Metzg. susceptible to this herbicide was isolated through single-plant selection in a Canadian cultivar. The objective of the ...

Development of drought-tolerant canola (Brassica napus L.) Through genetic modulation of ABA-mediated stomatal responses
Canola is one of the most important oilseed crops, and its seed yield and quality are significantly affected by environmental stresses such as drought. The phytohormone abscisic acid (ABA) is induced by drought and triggers stomatal closure to reduce transpiration, which accounts for >90% of water loss in plants. The ABA-mediated stomatal response is a dosage-dependent process that can be ...

Analysis of price volatility of mineral fertilisers: possible issues for European farmers
European farmers are currently affected by an increase in the price of fertilisers (from an index of 100 in 2005 to 150 in 2012 after it peaked at almost 200 at the end of 2008) that calls into question the future availability of these kinds of inputs. Since 2007, the strong demand from emerging countries, geopolitical tensions over natural resources, and the rise in the price of energy have been ...

Hexane Detection in Oilseed Operations - Case Study
Optical Gas Imaging (OGI) is a proven technology for locating Hexane and other Volatile Organic Compound (VOC) leaks in oilseed operations. OGI inspections can improve plant safety during routine operations, and reduce revenue lost to downtime during major overhauls. ROI payback in less than one year has been reported by major oilseed crush operations. A new Hexane and VOC leak detection ...

Seasonal slug pressure warning – crops at greater risk
Crops face a greater risk of slug damage and if left untreated, this can become extremely expensive for farmers, and is estimated to cost the potato industry up to £53 million per year*, as any slug damage reduces saleability and ultimately profitability of a crop. Slugs are most damaging to potatoes during the early stages of tuber bulking, which is starting to happen now. So make sure ...

Drones and scissors help decide fertilizer rate
Both Swedish and European field trials show that winter oilseed rape that has taken up a lot of nitrogen in autumn needs less nitrogen in the spring. A thinner crop, which has not assimilated so much nitrogen in the autumn, needs more N fertilizer in the spring. In order to determine the autumn’s nitrogen uptake, the so-called “cutting method” is often used in Sweden. Drones ...

Hexane Detection in Oil Seed Operation
A new Hexane and VOC leak detection technique using OGI is gaining favor among oilseed producers worldwide. This technique uses passive infrared imaging to make normally invisible gas plumes visible to the camera operator. The EyeCGas OGI camera has a minimum detectable leak rate for Hexane of approximately 0.3 grams/hour (1 gallon/year liquid Hexane). Hexane, a ...
