The latest issue of the “AgroExpert” magazine devoted to economics and finance in the agricultural sector features an article by Alexander Rudakov regarding the bedding of greenhouse tomatoes, as well as storage and growing rules. The President of ECO-Culture holding told explained why greenhouse tomatoes are stored longer than those grown in the open field and how modern agricultural technologies can affect the taste, healthiness, and organoleptic properties of the vegetables.
In the first part of the article, Alexander Rudakov spoke about the greenhouses being used in agricultural holding complexes. These are 8-meter-high structures with an aluminum roof, ventilation windows, a computer-based climate control system, and an automated supply of nutrient solution for plants. Developed by Dutch specialists, this technology is currently considered the most efficient and progressive in the industry.
In addition, greenhouses can be winter or spring type. In the first case, crops are harvested from early autumn to June, followed by the cycle reversal. In such constructions, an active role is played by the illumination of plants for stimulation of growth and fruiting. When it comes to spring-type greenhouses, tomatoes in those are grown from April to October, with the only natural, no additional light required. The production capacity of such greenhouses is lower, as the demand for greenhouse vegetables decreases in summer. Nevertheless, the general demand for the products is maintained all year round.
The author further explains how the problem of plant pests is being dealt with in greenhouse conditions. Here, chemical protection agents are not applied, only biological ones – the entomophagous insects, natural enemies of tomato pests. In fact, it is the chemicals that have a negative impact on the indices of tomato bedding, along with their healthiness and taste. The vegetables grown in a completely natural environment preserve their nutritional qualities and commercial presentation longer as they are not affected by either herbicides or growth stimulants.
In the ECO-Culture greenhouse complexes, tomato plants are grown on natural coconut substrate, the composition of which is as close to the composition of fertile soil as possible. In addition, weekly analyses of soil and nutrient solution are conducted – if it is found that some elements are missing, they are to be added to the substrate immediately.
One more factor that affects the tomato properties is the quality of the seed material. The agricultural holding uses premium seeds only supplied by Dutch breeders. These are the best hybrids in terms of sugar content, organoleptic, and taste indexes, derived from years of breeding work.
The combination of all these factors guarantees excellent results – useful and delicious tomatoes that preserve all their qualities throughout the whole month.
