The survey will cover potatoes, field vegetables, salads, protected crops and hardy nursery stock and will aim to give an overview of horticultural production in the area.
NFU West Midlands horticulture board chair Anthony Snell said: "Horticulture and the benefits of food production are not widely understood and what we are trying to do will be a hugely useful piece of research for everyone involved in the industry.
"It will tell us a lot more about the importance of the West Midlands and the huge diversity of the cropping. We are going to use the information to influence our customers, politicians, councillors and those who don't understand."
He said the survey would help "protect the British grower" and allow individual growers to demonstrate their level of input within the local economy while compiling expansion plans or applying for grant support.
He added: "We need to promote our area and get a much better understanding of what's going on. If we can justify the importance of our region nationally, it will influence public bodies to support us.
"When we get going with this we will really be urging farmers, growers and everybody involved in the industry to support this project and provide information that will be beneficial to themselves and to everybody involved."
NFU West Midlands senior policy adviser Clare Greener said the project will be NFU-led in partnership with the European Food & Farming Partnership, Wychavon District Council and the University of Worcester.
