The invention relates to vegetable production, namely to a process for determining the time of watering plants of cucumbers, tomatoes, peppers and eggplants.The process, according to the invention, comprises measuring the electrical resistance in the leaves of plants on watering day and in 3…5 days thereafter and calculation of difference of measured electric resistance values. Watering time occurs when is recorded the increase in the electrical resistance of the leaves of these plants by 5…10 kΩ in the vegetative growth and initial blossom periods, by 7…14 kΩ in cucumbers and 10…15 kΩ in tomatoes, peppers and eggplants in the blooming and fruit inception periods, by 10…15 kΩ in cucumbers, peppers and eggplants in the fruit growth period and by 15…20 kΩ in tomato plants in the fruit ripening period. |
