Cultivable land is shrinking day by day in urban areas and the population in urban regions is increasing rapidly, according to United Nations estimate the total world population will be doubled by the year 2050 accounting for 80% of the total population in urban areas. With increasing population and decreasing cultivable land in urban areas, production of fresh vegetables will be a serious issue. Vertical farming is a soilless technology of growing plants that serves as an alternative for cultivating fresh vegetables in a limited land area. The present study was carried out to standardize a vertical farming structure and an operating protocol for production of tropical fruiting vegetables viz., tomato, chilli, brinjal and leafy vegetables viz., palak, amaranthus, mint. A vertical farming structure made of 4 inch PVC pipe was used in the study and 3 inch net pots were used for growing plants and coir-pith was used as growing media. The experiment was laid out in Complete Randomized Design (CRD) with four replications. The observations on physiological parameters (leaf chlorophyll content, leaf area index), plant growth attributes (specific leaf area, relative growth rate, net assimilation rate) and quality parameters (nutrient content of leaves) of fruiting vegetable and leafy vegetable were assessed. Physiological parameters such as leaf chlorophyll content was the highest (1.30 mg/g) in palak plants and the brinjal plants recorded the maximum (0.97) leaf area index, with more flowers and fruits compared to tomato and chilli which had less flowers and fruits. Plant growth attributes like specific leaf area was the highest (6.73 cm2g-1) in brinjal, the highest net assimilation rate was recorded in mint (0.12 g g-1day-1) and brinjal recorded the highest relative growth rate (0.15 g g -1day-1). The tomato grown in vertical structure had the highest nitrogen (2.70 %) and potassium (2.93 %) content in the leaves, whereas palak recorded the highest phosphorus content (0.56 %), quality parameters like Ca (10.47%), Mg (3.36%) and protein content (3.61 mg/g) of leaves were found to be the highest in amaranthus leaves.
