    Photosynthesis is the basis of plant growth, and improving photosynthesis can contribute toward greater food security in the coming decades as world population increases. Multiple targets have been identified that could be manipulated to increase crop photosynthesis. The most important target is Rubisco because it catalyses both carboxylation and oxygenation reactions and the .   Goals / Objectives The project has three main objectives: 1: Develop alternative cover crop and tillage systems that decrease production costs, increase productivity, and enhance productivity of cotton production for the Southeast. 2: Evaluate three management factors (i.e., tillage, time of grain cropping, and cover crop management) for their impacts on plant and .

    Minimum soil disturbance: Zero tillage is ideal, but the system may involve controlled tillage in which no more than 20 to 25% of the soil surface is disturbed. Retention of crop residues or other soil surface cover: Many definitions of CA use 30% permanent organic soil cover as the minimum, but the ideal level of soil cover is site-specific. The Crop and Soil Science sequence emphasizes the scientific aspects of scientific agriculture together with rising plant production, quality, and profit by utilizing plant biological science and breeding and rising the soil physical, chemical and microbic characteristics to boost crop production. Sub Tracks: 1. Seed Science 2. Weed cultureStart Date:

    farmers’ perception of climate change and conservation agriculture in western ethiopia: the case of guto gida and sasiga districts Climate is a primary determinant of agricultural productivity. Ethiopia, one of the developing countries, is facing serious natural .   The realization of the contribution of peasant agriculture to food security in the midst of scenarios of climate change, economic and energy crisis, led to the concepts of food sovereignty and agroecologically based production systems to gain much attention in the developing world in the last two decades.

Crop management begins with the sowing of seeds, continues with crop maintenance during growth and development, and ends with crop harvest, storage, and distribution (Tivy, ).During seed sowing, a mechanized planter often opens a furrow in the prepared soil seed bed, places the.

Differences in marketable yields were even greater. Tunnels increased marketable fruit over uncovered plants by %, depending on the type of plastic used. The potential for protected culture to increase yields, protect crops from insects and disease, and decrease the need for pesticide use is significant, and selection of the correct type.

Nitrous oxide (N 2 O) is a potent greenhouse gas that can result in nitrogen loss from the soil. The scientific literature is deficient in studies that measure N 2 O emissions, NO 3 leaching, and crop performance across multiple sources of nitrogen fertilizer and changes in field practices.

However, there are tools and strategies available to consultants and producers to improve nitrogen use. West Tennessee’s supplemental irrigation management at a field level is profoundly affected by the spatial heterogeneity of soil moisture and the temporal variability of weather. The introduction of precision farming techniques has enabled farmers to collect site-specific data that provide valuable quantitative information for effective irrigation management.

Selection of Important Features for Optimizing Crop Yield Prediction Article in International Journal of Agricultural and Environmental Information Systems 10(3). Organic farming systems utilize carbon-based amendments, diverse crop rotations, and cover crops to build soil fertility.

These practices increase biologically available soil organic matter and beneficial soil microbe and invertebrate activities, improve soil physical properties, reduce disease potential, and increase plant by: Soil is a mixture of organic matter, minerals, gases, liquids, and organisms that together support life.

Earth's body of soil, called the pedosphere, has four important functions. as a medium for plant growth; as a means of water storage, supply and purification; as a modifier of Earth's atmosphere; as a habitat for organisms; All of these functions, in their turn, modify the soil and.

It’s called regenerative farming and it presents the startling proposition that agriculture is one of our best bets against climate change and a suite of other social and ecological challenges.

The history of agriculture can be seen as a long process of intensification, as society sought to meet its ever-growing needs for food, feed and fiber by raising crop productivity [].Coupled with socio-economic development, population growth and growing global food demand, the pressure originated from the resource supply becomes greater, for example, increasingly fierce Cited by: 1.

The objective of the Site-Specific Management Guidelines series is to provide a mechanism to assemble expert knowledge in a timely fashion on site-specific management in a form useful to farmers and their advisers.

Each Guideline addresses a specific issue related to site-specific soil and crop management.

Hydrologic models focusing on the unsaturated zone of soil are geared more toward simulating physical processes associated with water movement and are better suited for this study where the goal is not to predict yield but to simulate and compare soil water dynamics and water leaching losses between different bed geom etries in a plasticulture.The main body of the report is presented in Sections V to VII under four categories: (1) physical effects of man-made and natural factors on agricultural crop yield; (2) farm structure, profit- ability and risk changes due to agricultural crop yield changes; (3) secondary economic impacts due to agricultural crop yield changes (4) overall.Beneficial and Effective Microorganisms ® for a Sustainable Agriculture is not a substitute for other management practices.

It is, however, an added dimension for optimizing our best soil and crop management practices such as crop rotations, use of organic amendments, conservation tillage, crop residue recycling, and biocontrol of pests.
