Introduction At present, a great part of vegetable production in Chile is dedicated to industrial agronomy and one of the most important products is the tomato crop for industrial processing. Chile has a capacity of 180,000 tons of tomatoes per year, which is equivalent to 12,000 hectares of crop land. Among canned products tomato paste represents 38%. This is an important employment ...

Rice and wheat are major cereal crops in Nepal. Climate change impacts are widespread and farmers in developing countries like Nepal are among the most vulnerable. A study was carried out to assess the impact of climate change on yield and irrigation water requirement of these cereal crops in Bhaktapur, Nepal. Laboratory and soil-plant-air-water analysis showed silt-loam being the most ...

Maize (Zea mays L.) is a major crop on the Loess Plateau, and calculating the ratio of transpiration to evapotranspiration (T/ET) of maize is important for estimating field water balance. In this study, the sap flow method was adopted to measure transpiration (T) characteristics of maize. In order to calibrate the sap flow gauge, the sap flow rate was compared to the leaf T determined by the ...

"Eight years into implementing a zero-till policy across the farm, we’re seeing improved yields of 10 tonnes per hectare for our first year wheat, and five tonnes per hectare on winter beans. We’ve also noticed that we continue to see year-on-year improvements to soil structure and crop yields. “The winter beans have been extremely valuable in the rotation to ensure nitrogen and ...

Nigel Riches, Arable Technical Specialist for Certis, explains what he’s been seeing in the field. “Black-grass is a problem that in the past has generally been confined to the main arable areas, in the east of the country. “But increasingly we’re seeing this pernicious weed spreading further west each season. Where previously black-grass has not been a big issue in the ...

Wild cousins aren’t always appreciated at family gatherings. But when it comes to crops, the opposite is often true: Plant breeding has historically relied on genes from plants growing in the wild as a source of diversity that can be introduced into crop plants to produce new crop varieties that are more resilient, nutritious and productive than those currently cultivated. As human ...

Overview Growers interested in purchasing supplemental or sole-source lighting need to be able to accurately predict the economics and cost of ownership for the many different types of fixture layouts and options available on the market.  A useful financial estimate is the simple payback (or return on investment, ROI) of choosing one system over another.  The ROI takes into ...

Nitrogen fixation is one of the best examples of cooperation in nature. Soil microbes – naturally occurring bacteria in the soil – work with plants to pull nitrogen from the air. They turn the nitrogen into a form the plant is able to use. In return, the plant lets the microbes eat some of the sugars it makes. Faba beans (also called fava beans) are one example of plants that work ...

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 ...

Standards that credibly and effectively certify sustainable commodity production are important to both producers and consumers. Agriculture is the dominant user of water worldwide, so water sustainability in agriculture is an area of particular interest. In conjunction with Bonsucro, a sustainability standard setting body for the sugarcane sector, an indicator was developed to ensure that ...

The goal of this paper is to analyze the impacts of climatic variation around current normals on crop yields and explore corresponding adaptation effects in Arizona, using a unique panel data. The empirical results suggest that both fertilizer use and irrigation are important adaptations to climate change in crop production. Fertilizer use has a positive impact on crop yields as expected. When ...

High latitude regions experience unique conditions that affect the degradation rate of agrochemicals in the environment. In this study, data collected from two field sites in Alaska (Palmer and Delta) were used to generate a kinetic model for aminopyralid and clopyralid degradation and to describe the microbial community response to herbicide exposure. Field plots were sprayed with herbicides ...

Plants are far better than humans at turning sunlight into food. But they’re not nearly as good as they could be: Thanks to quirks in the systems that have evolved to capture solar energy and use it to build sugars from carbon dioxide and water, the conversion efficiency of photosynthesis is but a few percent at best. With the need to produce more crops growing even faster than human ...

This study investigates incentives and disincentives regarding adoption of controlled tile drainage (CTD) in a region of eastern Ontario, Canada, where CTD could be used prolifically from a biophysical standpoint, but is not. Irrespective of documented environmental and agronomic benefits of CTD, adoption remains low. Surveys and semi-structured interviews with producers and drainage ...

Uncertainties caused by climate change and population explosion require suitable methods for estimating grain yield during the growing seasons. This paper evaluates the applicability of the AquaCrop model in the region of western Kenya. The objectives of the study were to: simulate the long-term maize crop yields for the region using AquaCrop model for variable climate scenarios, and estimate ...
