  • What’s your potato storage strategy?

    With potato harvest nearing completion, the challenge will now be to maintain the condition of the crop, right up until supply to the customer. “It’s really worth stopping to consider that what you put into storage, is reflective of what you get out post-storage,” explains Morley Benson of Certis. “By this, I mean the quality of potatoes going into store, as well as the ...

  • Knowledge of Farm Practices – The Key for Successful Farming

    Agriculture plays an important part in the world economy. One-third of the economically active population obtains its livelihood from agriculture. In Asia and Africa, millions of small-scale farmers, fishermen, and indigenous people produce most of the food consumed worldwide, in most cases on very small plots of land. Agriculture is increasingly called upon to address a wide range of critical ...

  • China: agricultural production and groundwater

    As in many parts of the People’s Republic of China, Shanxi Province is experiencing reduced water security for the agriculture sector. Changing climate conditions, including reduced rainfall, are increasing reliance on groundwater resources in the province. Unsustainable groundwater use for food production intensifies the impacts of climate change, and cost-effective adaptation responses ...

  • Strategies to improve nitrogen use efficiency in winter cereal crops under rainfed conditions

    Developing fertilizer strategies that increase nitrogen use efficiency (NUE) could reduce unnecessary input costs to farmers and environmental impact of N losses. Two field experiments were performed in northern Spain to evaluate alternative N fertilization strategies to improve NUE in winter cereal crops (wheat [Triticum aestivum L.] and barley [Hordeum vulgare L.]). The strategies were: (i) ...

  • Effect of improved fallow on crop productivity, soil fertility and climate-forcing gas emissions in semi-arid conditions

    Abstract  The impacts of fallow on soil fertility, crop production and climate-forcing gas emissions were determined in two contrasting legumes, Gliricidia sepium and Acacia colei, in comparison with traditional unamended fallow and continuous cultivation systems. After 2 years, the amount of foliar material produced did not differ between the two improved fallow species; however, grain ...


  • Alternative crop rotations under mediterranean no-Tillage conditions: biomass, grain yield, and water-use efficiency

    In Mediterranean semiarid areas, barley (Hordeum vulgare L.) and wheat (Triticum aestivum L.) are major crops because they are well adapted to limited-water environments. In this study we tested the performance of alternative rotations to the typical barley and wheat monocultures in a rainfed Mediterranean semiarid area of northeastern Spain under a no-tillage (NT) system. Four rotations were ...

  • Crop response to rotation and tillage in peanut-based cropping systems

    Production of peanut (Arachis hypogaea L.) in reduced tillage systems has increased in the United States during the past decade. However, interactions of tillage system and crop rotation have not been thoroughly investigated for large-seeded, Virginia market type peanut. Research was conducted at two locations in North Carolina during 1999 to 2006 to compare yield of corn (Zea mays L.), cotton ...

  • Jojoba: A Potential Desert Oil Crop

    Jojoba (Simmondsia chinensis usually grows to a height of 1-2m and may reach heights of three meters or more under ideal growing conditions. S. chinensis has a normal life span of at least 100 years and may live more than 200 years. Pollination is via wind or insects. The fruit is a green capsule enclosing as many three seeds. When ripe (3-6 months after fertilization) the capsule splits and ...

  • The problems with the arguments against GM crops

    New evidence shows that arguments against GM crops are unfounded, says Margaret Karembu. The year 2013 marked the 18th consecutive year of commercial cultivation of genetically modified organisms (GMOs) or now commonly referred to as biotech crops. And in just under two decades, the volume of ...

  • Emissions from Crops - POST Note

    Agriculture contributes 9% of the UK’s greenhouse-gas (GHG) emissions burden and 10-12% globally. Although there is a long-term declining trend from UK agriculture, the sector may account for a larger share of overall emissions in the future as other sectors reduce emissions. This POSTnote focuses on reducing GHG emissions from growing and storing arable and horticultural crops. ...

  • Worms & Black Castings for an Abundance of Healthy Crops

    Earthworms are more than just good fishing buddies, they naturally incorporate organic material into the soil, increasing the amount of microbes, improving the health of the soil, and increasing plant productivity. Both worms and black castings from worms provide your garden or farm with a nutrient rich and robust environment, able to ...

  • Enriching African soils key to boosting crop yields

    In African countries where farmers have access and can afford to buy fertiliser, there is a profound difference in agricultural yields, a feature in Nature notes. The red soil found across much of the continent is low in organic matter and key nutrients, and intensive farming in ...

  • One crop, two ways, multiple benefits

    Nitrogen fixation is one of the best examples of cooperation in nature. Soil microbes – naturally occurring bacteria in the soil – work with plants to pull nitrogen from the air. They turn the nitrogen into a form the plant is able to use. In return, the plant lets the microbes eat some of the sugars it makes. Faba beans (also called fava beans) are one example of plants that work ...

  • Nitrogen fixation of Sulla under Mediterranean conditions

    Sulla coronaria (L.) B.H. Choi & H. Ohashi (=Hedysarum coronarium L.) is a Mediterranean forage legume grown extensively in rainfed Italian environments. Here we report the field quantification of its seasonal and annual N fixation, using the 15N isotopic dilution (ID) method, the influence of various nonfixing reference species on these estimates, and the allocation of fixed N between the ...

  • Can water use efficiency be modeled well enough to impact crop management?

    Crop water use efficiency (WUE, yield per unit of water use) is key for agricultural production with limited water resources. Policymakers and water resource managers working at all scales need to address the multitudinous scenarios in which cropping systems and amounts, timing and methods of irrigation, and fertilizer applications may be changed to improve WUE while meeting yield and harvest ...

  • Spectral Reflectance Properties of Winter Cover Crops in the Southeastern Coastal Plain

    Conservation tillage is a commonly adopted best management practice for reducing runoff and erosion, and increasing infiltration. Yet current methodologies in place to monitor conservation tillage adoption are largely inappropriate for regional or national assessments. A major goal of this study was to evaluate the spectral response properties of four alternative winter cover crops using remotely ...

  • Simulating switchgrass growth and development under potential and water-limiting conditions

    Anticipating a demand for switchgrass (Panicum virgatum L.) as a source for biofuel production, a crop simulation model of this crop can be a component of a biofuel decision support system. The objective of this effort was to develop and test a model for switchgrass, based on robust empirical relationships between plant behavior and the environment. The model simulates date of annual growth ...

  • Record Crops Predicted – Storing Chemicals in Suitable Vertical Storage Tanks

    The US is celebrating bumper crops this year, according to Farming UK. The publication states that the record-breaking corn harvest this year surpassed expectations of the US Department of Agriculture and it seems that because of the warm summer this year, that the UK could be following in its footsteps. Farming UK also reports on a trial that examines the good health ...

  • Spatial variability of Atrazine and Metolachlor dissipation on dryland no-tillage crop fields in Colorado

    An area of interest in precision farming is variable-rate application of herbicides to optimize herbicide use efficiency and minimize negative off-site and non-target effects. Site-specific weed management based on field scale management zones derived from soil characteristics known to affect soil-applied herbicide efficacy could alleviate challenges posed by post-emergence precision weed ...
