Assessing different cultivars for a specific region is a crucial step to identify suitable varieties that can thrive in the local climate. While a variety may exhibit distinct traits in a particular area, its performance and ability to maintain those characteristics may vary when cultivated in different locations. Additionally, the timing of planting also plays a vital role in determining crop production outcomes. Therefore, standardization of planting time is very important to get a good growth and excellent quality of cut flowers. By using staggered planting, the flowering period may also be extended for fetching a good price during different occasions. Therefore, the present investigation was conducted at Agri-tourism Centre, CCSHAU, Hisar (Haryana) during 2021-2022 to study the effect of planting time on growth and flowering of LA hybrid lily varieties under greenhouse. The investigation comprised four LA hybrid lily varieties along with four planting time (1 st fortnight of October, 2 nd fortnight of October, 1 st fortnight of November and 2 nd fortnight of November) and observations were recorded for various vegetative parameters. Out of the four-planting time, the varieties planted during 1 st fortnight of October performed better resulting in terms of maximum plant height, number of leaves, leaf length, leaf width etc. Among the varieties, Litouween performed overall best with respect to highest sprouting, plant height, leaf length, leaf width, stem lengthstem diameter etc.
