The global regulation of products of biotechnology is increasingly divided. Regulatory decisions for genetically modified (GM) crops in North America are predictable and efficient, with numerous countries in Latin and South America, Australia and Asia following this lead. While it might have been possible to argue that Europe's regulations were at one time based on real concerns about minimizin...

When processing grain and leguminous crops, it is necessary to carry out preparatory operations consisting in washing, moistening extraction. Existing technologies for crops small enterprises do not allow cleaning the surface hard-to-reach places, also have a long process of humidification The article presents design parameters plant which significantly speed up humidification, washing

∗ Corresponding author: WU Quan, senior engineer, CAAE, mobile phone:+8613621043045 Abstract: Grain production is of great importance to any country, especially to China. It is very important for local and central governments to get accurate main crops acreage information in time. One noticeable problem is that the estimated accuracy for crops acreage in a certain year is not high, so that Remo...

Bio-fortification of food crops is a cost-effective and sustainable agricultural strategy to decrease malnutrition arising from micronutrients deficiencies. Accordingly, the pot experiments have been conducted to investigate the effectiveness of various foliar-applied iron (Fe) fertilizers in increasing agro-morphological traits and grain micronutrients concentrations of bread wheat plants unde...

Several methods have been proposed to simulate yield in crop simulation models. In this work, we present a simple method to estimate harvest index (HI) of grain crops based on fractional post-anthesis phase growth ( fG = fraction of biomass accumulation that occurred in the post-anthesis phase). We propose that HI increases in a linear or curvilinear fashion in response to fG. The linear model ...

Canada ranks sixth in the world in wheat production with 27 million tonnes per year. (Canadian farmers also produce 22 million tonnes of other grain crops such as barley, corn, oats and rye.) Canada is the world’s second largest exporter of wheat with 70% of its production exported annually. The herbicide era began in the 1940s with the introduction of 2,4-D, a phenoxy herbicide that was adopte...

628 Abstract: Sorghum (Sorghum bicolor (L.) Moench) and pearl millet (Pennisetum glaucum (L.) R. Br.), ranking fifth and sixth in global cereal hectarage, respectively, are the most important coarse-grain cereals in the semi-arid tropical regions of Asia and Africa. Pearl millet displays better adaptation to and is grown in relatively more marginal environments than sorghum. Under subsistence f...
