  • New drying systems for crops

    Drying of agricultural products is an energy intensive operation. High prices and shortages in fossil fuels increase the emphasis on using solar energy as an alternative energy source, especially in developing countries. This paper deals with the construction of four different solar powered drying systems consisting of solar air heaters and drying chambers for small scale, natural convection, ...

  • Can genetic engineering help quench crops’ thirst?

    Researchers around the world are exploring how GMO technology might boost food production under hot, dry conditions. Roger Deal is trying to figure out how plants remember drought. An assistant professor of biochemistry and genetics at Emory University, Deal says most plants have a kind of memory for stress. When experiencing water shortage, for example, plants close ...

  • Reuse of constructed wetland effluents for irrigation of energy crops

    The aim of this study was to evaluate biomass production of promising ‘no-food’ energy crops, Vetiveria zizanoides (L.) Nash, Miscanthus × giganteus Greef et Deu. and Arundo donax (L.), irrigated with low quality water at different evapotranspiration restitutions. Two horizontal subsurface flow (H-SSF) constructed ...

  • Optimal crop planning using a chance constrained linear programming model

    A monthly time-stepped chance constrained linear programming (CCLP) model was developed to derive optimal cropping patterns and optimal operational strategies for the Sri Ram Sagar Project, with stochastic inflows. The stochastic nature of the inflows was incorporated into the model in its equivalent deterministic form. These equivalent deterministic inflow values were estimated from the annual ...

  • Commercial greenhouse water demand sensitivity analysis: single crop case study

    Today water distribution utilities are trying to improve operational efficiency through increased demand intelligence from their largest customers. Moving to prognostic operations allows utilities to optimally schedule and scale resources to meet demand more reliably and economically. Commercial greenhouses are large water consumers. In order to produce effective forecasting models for ...

  • Reuse of dairy lagoon wastewater through SDI in forage crops

    Abstract California has become the leading dairy products producing state in the USA. This has resulted in farms commonly milking several thousand cows per day. The care and feeding of the animals has produced large waste streams commonly collected and stored in lagoons. Environmentally safe handling and reuse of the lagooned wastewater is the objective of this study. A system of ...

  • Macroalgal standing crop estimate – fast method using ultralight aircraft

    A simple and low-cost method for monitoring macroalgal standing crops in shallow water consists of flying over and photographing the areas in an ultralight aircraft to determine the surface area of macroalgal mats. In the proposed method, photos are analysed by AUTOCAD software and mat density is then estimated in the field. Using mat density and bottom surface covered by mats, a rough estimate ...

  • Crop gene banks are preserving the future of agriculture. But who’s preserving them?

    As climate change makes crop diversity even more important, gene banks struggle to stay afloat. During the past few years of civil war in Syria, rebel fighters have destroyed Shia mosques and Christian graves, and burned and looted Christian churches while the Islamic State group has demolished priceless artifacts in the region. Nothing seemed sacred to the disparate ...

  • Unsound science? Transatlantic regulatory disputes over GM crops

    In the risk debate over genetically modified (GM) crops, Europe's regulatory delays have often been branded as "political", i.e. not based on science. Yet the US slogan "sound science" tends to conceal value-laden features of safety claims, their weak scientific basis, their normative framing and their socio-political influences. By contrast a "precautionary ...

  • Could traditional plants hold the secret to saving crops from pests?

    Researchers build on age-old practices to reduce food loss in Africa Without any effort at all, Hawa Saidi Ibura crushes dried beans, one at a time, between her fingers outside her home in Endagaw, a village in northern Tanzania. She’s holding a basket of a type of red bean eaten all over East Africa, but these beans ...

  • Advancements in chemistry are providing growers with flexibility when managing slug pressures in potato crops.

    Flexibility in slug control The mild and wet weather and lack of ground frosts seen this winter, means that being vigilant to slug activity will be key as we move into the potato planting season. Andrew Sprunt, Agrii’s Northern region potato technical agronomist, explains what growers can expect from the season ahead, and how to manage the potential impact at farm level, ...

  • Stevens Water and US Farm Bill Helps Farmers Optimize Crop Irrigation & Fertilization

    Agriculture is a major element for survival of the human race and of the economic system. 42 percent of the world’s laborers are employed in agriculture, making it by far the most common occupation. With agriculture using approximately 60 percent of available fresh water withdrawals, concerns continue to grow over farmers implementing water conservation practices. Also, increasing contamination ...

  • Intellectual property and Freedom To Operate in the flax breeding world: Canada in the global context

    Through one-on-one in-depth interviews of Canadian public sector flax breeders, this study explores issues around Intellectual Property (IP) and Freedom To Operate (FTP) in flax breeding from a Canadian perspective. The results are supported by a scan of flax breeding efforts worldwide, an in-depth patent analysis (using Patent Lens and the US Patent and Trademark Office (USPTO) databases) and a ...

  • Evaluation of an operational method for the estimation of emissions of nitrogen compounds for a group of farms

    The aim of this article is to evaluate a practical method for estimating nitrogen emissions on the scale of a group of farms, to be used in Life Cycle Assessment (LCA). The method rests on the estimation of nitrogen inputs and outputs to calculate the surplus of the annual nitrogen balance on the scale of a farm. The different gaseous nitrogen losses (NH3, NO, N2O, ...

  • A weekly operational planning model for a run-off-the-river system: some simulation results from the Tambiraparani river, Tamil Nadu, India

    In the present study, a weekly operational planning model has been developed using a simulation technique for the Tambiraparani river system in Tamil Nadu, India. A planning model has been developed incorporating the important features of the existing operational policy. Paddy is the main crop cultivated in three seasons, although banana is cultivated to an appreciable extent, it has not been ...

  • Assessing the economic benefits and costs of conservation tillage

    The economic benefits of the adoption of conservation tillage depend on site-specific factors, including soil characteristics, local climatic conditions, cropping patterns, and other attributes of the overall farming operation. While it is possible to draw some general inferences about components of economic returns and costs, a comprehensive assessment of the net private benefits from greater ...

  • 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 Best Practices for Using Plant Residues

    Plant residue are crop materials such as stems, leaves, and roots, that are left on the field after the harvest. In the past, farmers considered crop residue to be trash, that was usually destroyed by fire. However, today this practice is not recommended and highly is not used by farmers. There are two different ways to manage crop residues. The first method is tillage prior planting when plant ...
