The only time when pruning cucumbers is essential is when leaves are damaged due to movement in the aisles and disease or insect damage. Greenhouse plant spacing should provide: 1-2.5/m2 or more per plant, depending on pruning and training system.Recommended density is 33,000 - 60,000 plants/ha. If it is mini cucumbers, there can be 2 in a bag but for bigger English cucumbers one per bag is recommended.The spacing of the plants are at 16-18 inches apart. It was common for the fall and winter crops to be in the buckets longer to produce similar yield per plant. The fruits will also be of uniformly large size. Once a cucumber vine is trained to waist height, the plants’ secondary stems emerge and the formerly restrained vine explodes into a wall of foliage, flowers and fruits. Higher Plant Density Allows for More Crops Per Acre Hydroponics allows for higher plant density in one or more of the following ways: hydroponic crops can be grown 1. closer together than in soil, 2. grown vertically as opposed to horizontally, 3. in layers, and 4. with much less walking space between rows. Cucumbers prefer light textured soils that are well drained, high in organic matter and have a pH of 6 - 6.8. Plants grown in bags and pots produced similar marketable yields. Cucumber yield can be correlated with total leaf area. At this point additional support from stakes or string is usually needed around the outside of the planting if the vines and fruits are to continue to set fruit above the ground. Each bag contains about 12 liters of media in it. Pruning: Regular pruning results in healthy, sturdy plants that yield continuously. Figure 2.2: cucumber greenhouse with trellised plants 2.2.7 Soils. The more leaves are left on the plant the more the plant can photosynthesise and more energy there is for fruit production. This provides for 38kg.m-2 per season (estimate includes paths). It is clear that the plants will often have harvestable fruit at a younger age and provide more harvestable fruit per plant. If you plant cucumbers to use for pickling, plan on growing 3 to 4 plants per each quart of pickles you want to make. Generally a tomato plant should provide at least 10 kg fruit per plant in a full growing season starting from planting date in early September and ending in the last week of May. The plan called for three plantings at a density of 1.4 ft.2 (.13M2) per plant and an estimated yield of 30 lbs (13.5 kgs) per plant space per year under the worst case and a yield of 46-50 lbs (21-23 kgs) per plant space under the best case. m-2 (3.8 plant/m2). Increasing planting density will decrease size of fruits, but increase the number of fruits. Comparing the smaller cucumber data to the long English data is also useful.
