Impact of agricultural water reallocation on crop yield and revenue: a case study in China
Our study area in the People's Victory Canal Irrigation District of Henan Province in China has been transferring agricultural water to the city for municipal use. This study starts with an examination of the impacts of irrigation frequency, irrigation water sources, and irrigation water supply performance on crop yield and net crop revenue, using data from a survey of 182 households in the ...

Dryland crop yields and soil organic matter as influenced by long-term tillage and cropping sequence
Novel management practices are needed to improve the declining dryland crop yields and soil organic matter contents using conventional farming practices in the northern Great Plains. We evaluated the 21-yr effect of tillage and cropping sequence on dryland grain and biomass (stems + leaves) yields of spring wheat (Triticum aestivum L.), barley (Hordeum vulgare L.), and pea (Pisum sativum L.) and ...

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 ...

Glasshouse hygiene - the importance of staying clean
The nature of ornamental crops will mean plants are often in production for a long time, which can result in pest and disease carry over; so, it’s crucial that growers employ a rigorous hygiene and disinfection routine between crops. Start clean Starting the season with remnants of inoculum in the glasshouse, means growers are already on the backfoot, as the growing environment will always ...

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 ...

Land application of sugar beet by-products: effects on Nitrogen mineralization and crop yields
Land application of food processing wastes has become an acceptable practice because of the nutrient value of the wastes and potential cost savings in their disposal. Spoiled beets and pulp are among the main by-products generated by the sugar beet (Beta vulgaris L.) processing industry. Farmers commonly land apply these by-products at rates >224 Mg ha–1 on a fresh weight basis. However, ...

Soil quality and corn yield under crop–livestock integration in Illinois
Compared with traditional cropping systems, integrated crop–livestock systems have shown greater efficiency in improving soil quality and crop yield. The objective of this study was to determine how an integrated crop–livestock system affected soil properties and corn (Zea mays L.) yield when compared with continuous corn (CC). The study was conducted from 2004–2008 on a large-scale research farm ...

The impact of using GM insect resistant maize in Europe since 1998
Genetically Modified (GM) insect resistant (Bt) maize crops have been grown commercially in the European Union (EU) since 1998, and in 2006, there were plantings in seven EU member states. This paper reviews the specific economic impacts on yield and farm income as well as the environmental impact in respect of insecticide usage (where data exists). The analysis shows that there have been ...

Irrigation water requirements for seed corn and coffee under potential climate change scenarios
The impact of potential future climate change scenarios on the irrigation water requirements (IRRs) of two major agricultural crops (coffee and seed corn) in Hawai'i was studied using the Irrigation Management System (IManSys) model. In addition to IRRs calculations, IManSys calculates runoff, deep percolation, canopy interception, and effective rainfall based on plant growth parameters, site ...

Climate change, a storm in the coffee cup
Coffee is the third most consumed beverage in the world after water and tea. Food and Agriculture Organization (FAO) confirms ‘Coffee is the most widely traded tropical product, with up to 25 million farming households globally accounting for 80 per cent of worlds output’. In 2020, 87% of the global coffee production originated from the top 10 biggest coffee-producing nations, says ...

Simulating the Effect of Climate Change on Agriculture
Increased atmospheric CO2 levels and climate change are believed to contribute to extreme weather conditions, which is a major concern for many. And beyond extreme events, global warming is also predicted to affect agriculture.1,2While climate change is expected to affect agriculture and reduce crop yields, the complete effects of climate change on agriculture and the resultant human food ...

Controlling Barnyardgrass with Corn Hybrid Selection
Barnyardgrass is a summer annual grass weed with a global impact on corn production. Yield losses due to barnyardgrass competition have been estimated up to 45% or more for crops such as cotton and corn. Besides corn, it can also be a serious weed pest in rice, soybean, sugarbeet, cotton, and corn. Integrated weed management techniques can be used for control of barnyardgrass in corn. High ...

The cloud isn`t just for rain anymore
Precision agriculture has been a key enabling technology to achieve higher yields with lower cost and less environmental impact, while keeping the cost of food fairly stable Has global agricultural productivity increased or decreased in the last 25 years? It has, in fact, more than doubled since 1985. Next to advances in seed genetics, precision agriculture has been a key enabling technology to ...

So what is the role of commodity programs? Can they even be justified?
No matter what our area of daily activity, it is natural and even necessary that we myopically focus on the problems and issues of the day. But it is also important to step back once in a while to consider how the situations of today fit into a longer-term context. Along that line, we are in the midst of a series of columns that goes beyond the agricultural issues and policy motivations of ...

Marginal value of natural water in agriculture: a study in the suburbs of Mekelle City, Ethiopia
In areas where markets for natural water are lacking, information on its marginal value can be an important tool for proper pricing to achieve efficient allocation of the resource. This article investigates the marginal value of natural water (rainwater used as a proxy) in agricultural crop production in the suburbs of Mekelle City, Ethiopia, by econometrically estimating individual value ...

To Meet Agtech’s New Movers and Shakers, Look Beyond Buenos Aires
Last November, Arable participated in Silicon Valley Argentina in Rosario, a forum co-organized with Fundación CEDEF, Chacra Media Group, and Silicon Valley Forum. We’ve been to a number of ag shows in the US, and have never seen anything that compares to the caliber of this event. The best part was its forward-thinking focus on ‘the next generation of ag’: It was more ...

Probes reveal soil moisture’s many secrets
Soil moisture probes have been around for a long time, but they remain one of those mysterious agricultural instruments that only a small handful of people attempt to understand or use. “Part of the problem is people don’t trust the information,” says Ryan Hutchison of South Country Equipment in Saskatchewan. He was at Crop Connect 2019 in Winnipeg to give a presentation ...
