Present study on standardizing of container size and identification of suitable fruit crop for growing in containers at the roof top was carried out at ICAR-CISH, Lucknow during the years 2017–2019. Guava cultivar Lalit, Shweta and Citrus Sriganganagar Lime-1 and Kinnow were grown in different containers sizes (45x60 cm, 45x45 cm, 30x45 cm and 30x30 cm). Maximum canopy spread, trunk diameter, flower numbers and fruit numbers were recorded maximum in Lalit guava grown in 45x60 and 45x45 cm container size. Maximum fruit numbers (55/plant) and yield (7.2 kg) noted in Lalit grown in 45x60 and 45x45 cm containers size with average fruit weight 130.75 g. In Citrus Lime variety Shriganganagar Lime-1 wore 58 fruits (1.64kg/tree) with average fruit weight(28.70 g/fruit). Irrigation frequency varied 2–3 days during summer and 15–20 days in winter. It is concluded selected from the present study that fruit crops can successfully be grown in 45x60 or 45x45 cm size of containers with good fruit quality.
