Nitrogen use efficiency and nitrogen uptake of juncea canola under diverse environments
Nitrogen accounts for the largest energy input in oilseed production. Understanding N use characteristics of oilseed crops will help improve N use efficiency and minimize production costs. This study determined nitrogen use efficiency (NUE, defined as seed yield produced per unit of N supply), nitrogen fertilizer use efficiency (NFUE, defined as seed yield produced per unit of fertilizer N), and ...

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 ...

Rotational effects of cuphea on corn, spring wheat, and soybean
Diversifying crop rotations can give economic and environmental benefits. Cuphea (Cuphea viscosissima Jacq. x C. lanceolata W.T. Aiton) is a new oilseed crop that grows well in the Corn Belt. However, little is known about its rotational effect on corn (Zea mays L.), soybean [Glycine max (L.) Merr.], and spring wheat (Triticum aestivum L.), which are predominant crops in this region. A 4-yr study ...

Cuphea nitrogen uptake and seed yield response to nitrogen fertilization
Cuphea (Cuphea viscosissima Jacq. x C. lanceolata W.T. Aiton, PSR23) is an oilseed crop that is a rich source of medium-chain fatty acids. Progress has been made on improving cuphea agronomically, but little is known about N fertility requirements for optimum cuphea production. The objective of this study was to determine the N necessary for maximizing seed yield and oil content. Experiment 1 was ...

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 ...

Yield and water use response of cuphea to irrigation in the Northern Corn belt
Cuphea (Cuphea viscosissima Jacq. x C. lanceolata W.T. Aiton) may be prone to drought stress, yet little is known about the yield response of this new oilseed crop to irrigation. A field study was conducted in western Minnesota on a Barnes loam soil (fine-loamy, mixed, superactive, frigid Calcic Hapludolls) in 2002 and 2003 to compare yield and water use of irrigated and nonirrigated cuphea. ...

Things You Need To Know Feed Ingredients
Feed ingredients are broadly classified into cereal grains, protein meals, fats and oils, minerals, feed additives, and miscellaneous raw materials, such as roots and tubers. These will be discussed in separate headings below. More information on measuring the nutrient composition of ingredients and the process of formulating poultry feeds is available in the section on feed formulation. ...

5 ways drones can help farmers in spring
Throughout the whole growing season, drone images can be a good tool for farmers to make their work more effective. Already in spring, drones can be used in the field to help answer important questions: How was the establishment of winter crops and how has the winter affected the crops? Where do I need to reduce or increase the seed rate next time? Should I change the time of fertilization? Where ...

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 ...

Farmonaut For Crop Area and Yield Estimation
INTRODUCTION: CROP AREA ESTIMATION The two components of agricultural production estimation are crop area and yield estimation. In order to estimate yield, Producers generally measure the amount of a particular crop harvested in a sample area to estimate crop yield. The harvested crop is then weighed, and the entire crop production of the area is approximated from the sample. A method for ...

Rethinking food production for a world of eight billion
The World Food Programme and the Chinese government jointlyannounced that food aid shipments to China would stop at the end of theyear. For a country where a generation ago hundreds of millions of peoplewere chronically hungry, this was a landmark achievement. Not only hasChina ended its dependence on food aid, but almost overnight it has becomethe world’s third largest food aid donor. The key ...

Seedbed preparation
Timing and weather, as well as kit, are key parts of seedbed preparation on the min-till system. The search for lower establishment costs has led one Warwickshire grower to ditch the plough and opt for a min-till approach that offers the capability to direct drill too. Geoff Ashcroft looks at the system in use. The ability to direct drill cereals does hold a certain appeal, particularly when ...

Behavioural and chemical ecology underlying the success of turnip rape (Brassica rapa) trap crops in protecting oilseed rape (Brassica napus) from the pollen beetle (Meligethes aeneus)
There is increasing interest in the use of trap crops as components of integrated pest management (IPM) strategies. Understanding the mechanisms underlying host plant preferences of herbivorous pests can lead to improved effectiveness and reliability of the trap crop. We investigated the behavioural and chemical ecology underlying the success of turnip rape, Brassica rapa, trap crops in ...

AminoA+ Update and Autumn Recommendations 2016
AminoA+ Update With harvest 2016 coming to a close and also the first year of our commercial sales of AminoA+ we thought we should review the results and also make some recommendations based on this years’ experience. Yields OSR and Winter Barley yields were reportedly generally 30% down on 2015 levels this is undoubtedly a results of lack of sunlight in the early summer. (Two ...

Drill decision proves right one for suffolk farmer
When Peter Norman of B E Norman & Sons, Hall Farm, Wisset, Nr Halesworth, ordered his new 4 metre DP400A Moore drill in May 2004, he had never even seen one in the flesh. “I liked the look of the coulter system” he said “and knew that because it was in effect, a similar principle of depth control to a sugar beet drill, but much more heavy duty, it would easily cope with our ...

Growth and yield response of rice varieties to foliar application of Boron | JBES 2020 @environmentalxpart
Abstract A field experiment was conducted during the Kharif season of 2018-19 at Rice Research Station Bahawalnagar on the calcareous sandy loam soil to assess the effect of foliar application of boron on growth & yield components of rice varieties (Kissan & Punjab Basmati 2016).The foliar application of boron aqueous solution was used as treatments comprised of control, 0.5kg/ha, ...
