Goal of the trial design

The trial took place in 2 greenhouses, each with their own irrigation system. In all other aspects, like size, climate, varieties, watering frequency, watering volume, both greenhouses are analogous.

  • One greenhouse was treated with Sili-Fert P once every 2 weeks.
  • The other greenhouse did not receive treatment with Sili-Fert P and served as control.

The goal of this trial was to monitor the effect of Sili-Fert P on yield on the one hand, and on the quality of the fruit on the other hand.

  • To monitor the effect on yield, the grower recorded the kilograms per m² and pieces per m² harvested over a 14 week period.
  • To asses the effect on quality, the average fruit weight (AFW) was also recorded over a 14 week period. The shelf life was also evaluated.

For the shelf life assessment, 10 harvestable cucumbers of the same variety of each greenhouse were collected and were weighed immediately after harvest to log their initial weight. Afterwards, the cucumbers were weighed once every other day for a period of 12 days. Weight loss is directly related to water loss from fruits, making this an important parameter to measure. Furthermore, the cucumbers were evaluated visually by classifying them as firm or mushy. The evaluations were documented with photographs.

Cucumber 2


After 14 weeks of cultivation, the data was statistically processed. The test showed that the average fruit weight from the cucumbers from the Sili-Fert P treated greenhouse was significantly higher than the AFW of the cucumbers from the control greenhouse (see table 1). The kg/m² and pcs/m² displayed an explicit trend with higher values of the Sili-Fert P treated greenhouse compared to the values of the control greenhouse.

Both cucumber batches lost approximately the same amount of weight over the 12 days during the shelf life trial, with a slightly better result for the batch treated with Sili-Fert P. Furthermore, a clear trend was also observed in the number of firm vs. mushy cucumbers of both batches.

Both batches start with 100% firm cucumbers, but after 7 days of storage, the control batch drops to 75% firm cucumbers, whereas the treated batch only decreases to 90%. After 12 days of storage, the control batch drops even further to 70%, while the treated batch still has 85% firm cucumbers.

Disinfection of equipment inhibits the spread of Chlamydospores of Fusarium Oxysporum

Fusarium lettuce wilt can be killed off completely on tools and other equipment by selecting the correct disinfectant. However, it is important to pay proper attention to dosage and contact times.
