Plant growth regulator use in winter rapeseed

Why was this topic chosen and will there be any trials/demonstrations?
Since it has not been determined in Latvia when to use which plant growth regulator in rapeseed to obtain the best results (for example, to improve winter hardiness or ensure a higher yield), the data obtained during the project will help every rapeseed grower choose the most appropriate plant growth regulator or, conversely, make a decision not to use it.
Due to the lack of research, representatives of plant protection user companies and consultants are unable to provide appropriate recommendations, as a result of which the farmer is often unable to make an objective decision. End users will be offered a unique program – a tool on a computer, where by entering the amount of heat accumulated by winter rapeseed in a specific field, they will be given a justification to choose to use a strong, medium or weak plant growth regulator or not to use it at all.
During the project, industrial trials with 24 variants will be set up – with some sowing times and different doses of plant growth regulators. In turn, practical trials will be set up on the farms of the project's cooperation partners, linking them with meteorological data. Based on the obtained database, the programmer will create an easy-to-use tool for counting heat days and making decisions.
