Abstract:

Aeroponics is one of the advanced techniques to cultivate plants without soil with minimal water and nutrient consumption. It is an eco-friendly approach widely used for commercial cultivation of vegetables to obtain the supreme quality and yield. In this context to harvest potentiality of the technology an experiment was designed to standardize the pH of the solution for tomato. The experiment was carried out under Completely Randomized Design (CRD) with three replications during the year 2017-18 at UAS, GKVK Bengaluru. If optimum pH doesn’t prevail in the medium, though the nutrients are present in sufficient amount they will not be available to plants. Thus based on the earlier experimental results Hoagland’s nutrient solution was prepared with five different levels of pH ranging from 4.5 to 7.0 and studied till 30 DAT. Higher total seedling length was noticed in pH 6-6.4 (118.4 cm) at 30 DAT followed by 5.5-5.9 pH range (115.9 cm) and lower was recorded in 4.5-4.9 pH range (39.6 cm). Thus tomato performed better in Hoagland’s nutrient solution at pH ranging from 5.5-6.5.
