  • The European seedless type is parthenocarpic which means it produces fruit without pollination.
  • Gynoecious types (with few male flowers) are acceptable since they are less vigorous, produce more and can withstand clod temp.

Seed Germination for cucumber:-

  • Seeds germinate in 2 to 3 days and 28° is the optimum temp for germination, for seedling 25° is optimum!

Temperature requirements for cucumber.

  • Cucumber grows best under high air temperatures [50 to 55°F (26.6 to 29.4°C)]
  • Cucumber can withstand high and low temp but not greater than 56°F (30°C)]!
  • The nutrient solution temperature should not exceed 71.6°F (22°C) it happens when the air temp is higher than 40°!
  • And make sure if air movement between the canopy is good.
  • Space between rows should be 4 to 5 ft (1.2 to 1.5 m) with plants spaced 12 to 18 in. (30 to 45 cm) in the row.
  • High plant density can reduce fruit set and size and increase the potential for disease infestation.

Pruning of cucumber foliage:–

  •  It is to make a single stem using two pruning systems, an original umbrella or a modified umbrella

The cucumber plant can be trained to a support wire in four different configurations: canopy, vertical cordon, inclined cordon (V-cordon, V-training), and guernsey

Remove all the suckers that form between the leaves and stem on the main stem until the last few near the supporting cable as mentioned earlier, just pull them off by hand. The first seven to eight fruit should also be removed so that the plant can become vigorous enabling it to yield heavily later!

  • Pruning and training create conditions  that establish complete leaf coverage (i.e., no light reaching the ground)

Foliage care.

  • Dead, diseased, or insect-damaged foliage should be removed as soon as identified.
  • If your fruit load is too heavy, plant vigour is reduced, and maturing fruit may be stunted.
  • unmarketable Fruit should be identified early and removed.
  • The curvature of the fruit, known as “crooking,” can occur early in the fruit development stage, and such fruit should be removed from the Foliage.
  • cucumber tastes bitter when the cucumber plant is under stress, similar to that causing crooking
  • increasing too much EC can result in slow plant growth and poor fruit set.
