Temporal yield variability under conventional and alternative management systems
Year to year variation in yield is an inherent risk associated with crop production and many growers rely on intensive mechanical or chemical inputs to preserve crop yield in the face of fluctuating environmental conditions. However, as interest grows in alternative crop management systems which depend less on external inputs, determining the degree to which management systems can impact the ...

Wheat: Preparing the Root System for Tillering and Vegetative Growth
The number of tillers is the primary yield component of straw cereals, including wheat, the world’s most widely grown cereal. The number of tillers is fundamental to crop yield development. It will compensate for the loss of plants during sowing due to poor planting. It is directly related to the final number of ears. Three leaves constitute a tiller, and this tiller can be transformed ...

Impact assessment of pre- and post-sown irrigation with Post Methanation distillery Effluent on soil health and crop yield
Field experiments were conducted to assess the optimum dilution of Post Methanation distillery Effluent (PME) to utilise as an organic nutrient source for growing rice and wheat crops. Dilution levels of distillery effluent significantly affected the biomass production as well as grain yield of rice and wheat crops. Levels of organic carbon and NPK were significantly higher in effluent treated ...

Impact of fly–ash–amended soil on growth and yield of crop plants
Fly Ash (FA), a waste product of thermal power stations, has great potential for use in agriculture, because it contains almost all macro as well as micronutrients. In view of the potential disposal problem of FA, this investigation was carried out to search an economical and eco–friendly solution of its disposal by using it as nutrient source in agriculture for growth of crop plants. FA ...

Novel simulation-based algorithms for optimal open-loop and closed-loop scheduling of deficit irrigation systems
The scarcity of water compared with the abundance of land constitutes the main drawback within agricultural production. Besides the improvement of irrigation techniques a task of primary importance is solving the problem of intra-seasonal irrigation scheduling under limited seasonal water supply. An efficient scheduling algorithm has to take into account the crops' response to water stress at ...

The Role of Soil NPK Sensors
Agriculture is a crucial sector that provides food for the world's population. As the population continues to grow, the demand for food also increases. To meet this demand, farmers must produce more food with fewer resources. One of the ways to achieve this is by optimizing crop nutrition and maximizing yield. Soil NPK sensors have emerged as a useful tool for farmers to achieve these goals. Soil ...

Corn grain yields and yield stability in four long-term cropping systems
Most long-term studies evaluate only average crop yields and overlook year-to-year yield variability, which could be highly significant. Our objectives were to evaluate the impact of long-term cropping systems and fertility management on corn (Zea mays L.) yield and yield stability. Cropping systems were (i) CC, continuous corn; (ii) CS, corn-soybean [Glycine max (L) Merr.]; (iii) 4C4A, 4 yr ...

Reduced soil tilling helps both soils and yields
Agriculture degrades over 24 million acres of fertile soil every year, raising concerns about meeting the rising global demand for food. But a simple farming practice born from the 1930's Dust Bowl could provide a solution, according to new Stanford research. The study, published Dec. 6 in Environmental Research Letters, shows that Midwest farmers who reduced how much they overturned the soil -- ...

O3 sensitivity in a potential C4 bioenergy crop: Sugarcane in California
The C4 perennial grasses have many potential virtues as bioenergy crops—high productivity and water use efficiency, multiyear crop cycle that minimizes replanting costs, and wide environmental adaptation. In the productive San Joaquin Valley (SJV) of California, these species also confront high levels of ozone (O3) air pollution. It is often assumed that C4 species will exhibit tolerance to O3, ...

How to Help Grapevines Recover after a Difficult Frost Period
100% : this is the percentage of a vineyard that can be damaged by frost Cold snaps and frosts have hit many orchards and vineyards these last few weeks in France. High yield reduction will be expected due to these cold waves, occurring after weeks of heat and crop development. During dormancy, grapevines can support temperatures as low as -15°C. However, as soon as the vines bud, they ...

Call for Funding to Support Vertical Farming in Cameroon
An ambitious new project to redesign agricultural practices and food stability is currently underway in Cameroon. The project is managed by the CDVTA, Community Development Volunteers for Technical Assistance, in collaboration with the Association for Vertical Farming and aims to improve the lives of rural farmers in North West Cameroon by developing local skills and knowledge. Factors such as ...
