I am growing salad cucumbers, variety Mini Angel from Semillas Fito, spain, in greenhouse.

I see few cucumbers are turning yellow, and few more deformed, any reasons why and remedy for this?

The plants look healthy.

Kind regards

Welcome!

I can think of 3 causes of deformed cucumbers:

1. Incomplete pollination of the flowers

2. Hot, dry weather

3. Over-fertilizing

And related to #1, there may be few if any pollinators in your greenhouse. This can be rectified by employing hand pollination : https://www.gardeningknowhow.c...

I agree on the reason most likely being a lack of pollination.

Friends, the agronomist visited my location and pointed out that its coz of Boron and Calcium deficiency.

So giving a Boron EDT foliar spray today alpng with CaNO3 to root zone.

Will keep updating the progress.

@Mohanurs, Interesting. I've never encountered that. As has been mentioned, insufficient pollination followed by hand pollination has always cured the problem for me. Thank you for the information.

If it is a boron and calcium deficiency, your plants would also be affected. You only mentioned the fruit. A calcium deficiency would cause the leaves to be cupped and the fruit would have blossom end rot. A boron deficiency would result in the leaves looking chlorotic, then dying. The growth tips would also die - there would be no fruit set at all.

Adding some Epsom salt wouldn't hurt either. Read up on it.
