Applications crop production

It was emphasized in the two conference reports (36, 37) that proper understanding and application of allelochemicals could lead to potentially increasing the crop productivity by protecting the crop plants from natural toxins and by increasing the crop yields by the action of natural stimulants. 

We are learning from experience and research that there are problems in crop production from repeated use of herbicides without mixing partners, or without alternating the use of herbicides with different modes of action. Not only do the resistant weeds become problems, but they lead to additional applications of the herbicides, adding further expense and further pressure to the development of resistant populations. 

Atrazine is the key herbicide facilitating ecofallow corn and sorghum production in the semi-arid Great Plains, where crop production is often uncertain and profits to farmers are often marginal. The success of atrazine in ecofallow is attributable to its duration of weed control as a soil-applied herbicide, the broad spectrum of weeds controlled, the low cost per area treated, and its safety to crops. In this semi-arid environment, maintaining weed-free fallow with repeated applications of nonresidual herbicides is not an economically viable alternative to atrazine. 

Plant diseases cause serious losses in crop production. Pesticide application is currently the primary way to control crop disease, but it has raised an array of environmental problems. Achieving sustainable agriculture will require avoiding a...

Economic data for the production and utilization of Jerusalem artichoke are relatively scarce, because the crop is not currently grown on a large commercial scale. However, there are some economic analyses for crop production and the use of Jerusalem artichoke for bioethanol and inulin production that highlight its potential. Bioethanol is in demand as a gasoline additive and biofuel, while inulin is increasingly used as a food ingredient. The tops and tubers of Jerusalem artichoke also have many other potential applications. 

The adoption of Se-enriched fertilizer in crop production to improve the content of Se in agricultural products is a fundamental strategy. The use of Se-enriched varieties of crops and their effects on the environment are closely related. The Se concentrations in the same black rice variety, which are planted in two different places can reach a difference of 2.87 times. Reports show that the main Se supplementation method is selenite application both at home and abroad. Soaking or spraying the crops with different concentrations of sodium selenite, so that Se can be absorbed by the crops and the agricultural products, can be achieved with certain Se contents.
