A survey of factors involved in crop maturity
The time necessary for crops to successfully complete reproduction is species and environment dependent. Lifecycles can be completed in a few weeks or take several years depending on the plant species. Crop development is divided into phenophases that are affected primarily by light and temperature changes, interacting with phytohormones. Some species are influenced more by light and others by ...

Assessment of aquacrop, cropsyst, and WOFOST models in the simulation of sunflower growth under different water regimes
This work compares the performance of AquaCrop, a crop simulation model developed by FAO, with that of two well established models, CropSyst and WOFOST, in simulating sunflower (Helianthus annuus L.) growth under different water regimes in a Mediterranean environment. The models differ in the level of complexity describing crop development, in the main growth modules driving the simulation of ...

Agricultural innovation and biotechnology development towards sustainable goals: can we make it more pro-poor?
Agriculture continues to change – driven by innovation and new technology. Genetics and breeding have revolutionised agricultural systems, and the 'Green Revolution', based on higher yielding varieties of dwarf wheat and rice, is arguably the greatest achievement in food crop development. Gene technologies now offer additional opportunities, where new traits improving crop protection ...

Seasonal changes in the performance of a catch crop for mitigating diffuse agricultural pollution
An in situ technology for mitigating diffuse agricultural pollution using catch crops was developed for simultaneously preventing nitrate groundwater pollution, reducing nitrous oxide (N2O) gas emissions, and removing salts from the topsoil. Seasonal changes in the performance of a catch crop were investigated using lysimeters in a full-scale greenhouse experiment with 50 d cultivation of dent ...

An App that Supports Decision-Making and Planning
Informed decision-making leads to smarter decision-making. As Elston Solberg, Crop Intelligence’s own expert agronomist, has said before—"trust the data so you can crush the agronomy.” The data that our Crop Intelligence app provides and the support that our team offers helps you inform your planning and decision-making—both in-season and before next season. Fertility ...

Corn stover to sustain soil organic carbon further constrains biomass supply
Sustainable aboveground crop biomass harvest estimates for cellulosic ethanol production, to date, have been limited by the need for residue to control erosion. Recently, estimates of the amount of corn (Zea mays L.) stover needed to maintain soil carbon, which is responsible for favorable soil properties, were reported (5.25–12.50 Mg ha–1). These estimates indicate stover needed to maintain soil ...

How to get seed rates spot on for target market and harvest scheduling
Potato agronomy is complex and requires a lot of planning, monitoring and evaluation throughout the production process. CPM finds out how digital agronomy tool Crop4Sight can help in all three areas as preparation for the 2023 season gathers paceIf you fail to prepare, you prepare to fail – an adage that is very relevant when thinking about potato crop establishment, with half the agronomy done ...

Establishment and growth of self-seeded winter cereal cover crops in a soybean–corn rotation
Perpetuating cereal cover crops through self-seeding may increase adoption by reducing risk and cost. Winter rye (Secale cereale L.), wheat (Triticum aestivum L.), and triticale (x Triticosecale Wittmack) were used to develop self-seeding cover crop systems in a soybean [Glycine max (L.) Merr.]–corn (Zea mays L.) rotation. Cereals were planted and managed chemically and mechanically in varying ...
