Irrigation And Fertilizer Tips For New Vegetable Growers
Compared to other variable costs, fertilizers are not the largest part of the budget in conventional greenhouse production. Nevertheless, over the course of the season, mistakes in fertilizer use can lead to significant damages or crop losses. That makes this an important topic for ornamental growers who are experimenting with growing vegetable crops. This article will emphasize major differences between fertilizers used in vegetable production and in ornamentals production. The different nutrition strategies, monitoring and water volume per plant will also be explained. Fertilizer In ornamental production, nutrients are delivered using various water-soluble fertilizers through a fertilizer injector, through the use of controlled-release fertilizers, or a combination of the two. There are numerous fertilizer mixes available with all the needed nutrients already included. The fertilization rate is often given in parts per million (ppm) of nitrogen (N), which is a way of expressing the fertilizer concentration. At younger stages, plants will […]

Labor Management Tips For Greenhouse Vegetables
Shifting production from ornamentals to vegetable crops can be relatively simple with regard to production. However, there are a number of things you will need to consider with regard to the organization and training of your staff. This article will focus on labor management applicable to a variety of greenhouse vegetable crops. The labor requirements (hours/acre) per month are different for the three main vegetable crops produced in greenhouses: tomatoes, cucumbers and peppers. It is important to know that cucumbers and peppers use 19 percent and 32 percent less labor respectively than tomatoes. Also, it is good to know that tomatoes require more care from employees during the course of the season. Requirements will range from 12 hours per 10,000 sq. ft. (at the beginning of the crop) to 37 hours per 10,000 sq. ft. (at peak where all tasks need to be taken care of). For a long tomato […]

Four Food Safety And Handling Considerations For Greenhouse Vegetables
Vegetable production isn’t all that different from ornamentals production for a veteran grower. But if you’re growing vegetables to harvest and market rather than selling the plants themselves, there are some important differences. As an edible crop, there are some food safety and handling considerations you may not have thought about. Before you decide to add produce as a new greenhouse crop for your operation, be sure to consider the following issues: 1. Water quality and testing. It may be necessary to make a complete water analysis when growing vegetables in the greenhouse. Testing irrigation water for pathogens and keeping water test records are good agriculture practices and an important part of on-farm food safety planning. Most laboratories will test for E. coli and other possible pathogens. For instance, a greenhouse facility using pond water or an artesian well should do a water analysis more frequently during warmer months in order […]

Retrofits And New Equipment For Greenhouse Vegetables
Shifting production from ornamentals to vegetable crops can be relatively simple with regard to production. However, there are numerous components of a greenhouse that, with a bit of retrofitting, may result in greater efficiency and a better crop. This article will focus on basic elements a grower should consider before moving into greenhouse produce at any significant level. Retrofitting a greenhouse is all about spending money to make more money. In many cases, a new crop like vegetables may be the easiest way to see new technologies impact the bottom line. However, the benefit of a new crop performance should not be overlooked. There are a number of points to think about before you try to grow vegetables. 1. Irrigation: For growers who have only grown bedding plants or flowering potted plants, adapting your irrigation practices to vegetable crops can be a challenge. There are several things you will need […]

Vegetable Insect And Disease Issues You Need To Know
Most flower growers are finished with their crops by the end of May or the beginning of June. Even if they plan to produce a fall crop, there is likely some down time, so many are looking at the potential for growing vegetables in those empty greenhouses between production cycles. But vegetables can be a very different crop to grow all the way to fruit harvest, and that can present some unique challenges for growers used to working with ornamental crops. For example, growers who decide to produce tomatoes will find that this crop needs to stay at least 15 weeks in the greenhouses to harvest seven to eight trusses (or flower branches which set four to five fruit each). This is twice as much time in the greenhouse compared to many annual plants. That means twice as much time to develop unwanted populations of insect pests and diseases in […]

Three Keys To Success In Greenhouse Vegetables
So – you are thinking about growing produce. I have worked with many growers both in the U.S. and Canada on incorporating vegetables into their greenhouse production over the years. Even as more growers become interested and the market gets more competitive, growers can still make good money for their products. In my experience, the keys to success in the greenhouse vegetable industry lie mainly in three factors: market know-how, and costs. Understand The Market Although I am based in Canada, the market for greenhouse vegetables here in Quebec is very similar to the market in the U.S. It boils down to a very few well-defined aspects. The market looks for smaller, tastier and more practical fruits. There are multiple types of tomatoes, sweet peppers, cucumbers and lettuces that meet those desires, and many different containers and displays to gain consumers’ attention. The demand for local fruits and vegetables and […]
