Due to strong eggplant growth and the formation of large vegetative weight quantities in growing under glass and foil it was deemed useful to conduct studies on the effect of pruning intensity on yielding of this vegetable in rooms. The aim of the foregoing studies was to demonstrate the effect of plant pruning and topping manner on yield quantity and earliness. The experiment was conducted in the years 2001–2003. The study objects were the plants of ‘Epic F1’ cultivar. Eggplant was grown in rigid foil cylinders of the capacity of 10 dm3 in the peat substrates. The plants were trimmed, managing for one, two, three, four, five, six guiding shoots and in the natural form, without trimming. Topping cut was performed in each combination after the first fruit harvest. The experiment was established and conducted as a two-factor one, in accordance with a complete randomization system: A – pruning method (a = 7), B – topped and non-topped plants (b = 2). Each combination of the examined factors was represented by 20 plants (experimental units). A significant effect of pruning intensity on the quantity and earliness yielding was demonstrated. The highest marketable fruit yield was obtained from plants managed for two (3.82 kg.m-2), three (3.98 kg.m-2), and four (3.87 kg.m-2) guiding shoots. Managing for one guiding shoot significantly decreased the total and marketable fruit number. The highest early yield was collected from plants managed for one and two guiding shoots. A single topping cut performed after the first fruit harvest did not affect marketable yield and marketable fruit number.

The experiments were carried out in 1998–2000 in a unheated plastic tunnel. The effects of single plants topping on the quantity and quality of the yield of three cultivars of eggplant (Solanum melongena L.) – ‘Black Beauty’ ‘Solara F₁ ’ and ‘Epic F₁ ’ in the experiment was determined. No significant influence of the method on the marketable yield and the number of fruits in marketable yield was found. Plants topping also had no positive effect on mean weight of marketable yield fruit. Results achieved in present experiment point out that fruit size (length and diameter) more depends on cultivar and weather course than plants topping procedures.

The effects of a differentiated row spacing as well as topping and lateral bud pruning on the yield and quality of light cigarette type of tobacco were tested on a 3-year field experiment. It was noticed that topping and lateral bud pruning had positive effects on yield level. A wider row spacing as well as the pruning of inflorescence and side buds lad to positive changes in tobacco's product quality as a results of an increase in the carbohydrate content of leaves.
