Abstract: The present study was carried out at the experimental farm of the Department of Floriculture and Landscape Architecture of Dr. Y.S. Parmar University of Horticulture and Forestry, Nauni, Solan under naturally ventilated polyhouse conditions during 2014-15. The experiment was laid out in a Randomized Block Design having 10 treatments of drip irrigation levels replicated thrice. The observations on various growth, flowering and yield were recorded at the time of peak flowering. Maximum values w.r.t. plant height (94.12 cm), stem length (89.77 cm), stem thickness (8.41 mm), number of shoots per plant (44.08), number of leaves per plant (41.23), number of flowers per stem (16.88), number of flowers per cyme (5.50), inflorescence diameter (9.25 cm), vase life (20.05 days) as well as yield per plant (41.19 cut stems) in those plants which received T10 treatment i.e. 10 litres/m2 (October- February) and 12.5 litres/m2 (March-September). As regards the effect of flushes, maximum plant height (107.87 cm), stem length (103.96 cm), stem thickness (7.60 mm), number of shoots per plant (47.31), highest number of leaves per plant (42.72), maximum number of flowers per stem (16.09), number of flowers per cyme (4.67), inflorescence diameter (8.71 cm), higher vase life (17.14 days) as well as yield per plant (40.75 cut stems) was recorded in 1st flush. The interaction, T10×B1 i.e. when plants were irrigated with 10 litres/m2 (October- February) and 12.5 litres/m2 (March-September) during 1st flush recorded maximum values in terms of most of the growth and flowering parameters of commercial importance. Hence, it is concluded that for better growth, flowering and yield of cut flowers, the alstroemeria plants be irrigated with the 10 litres/m2 (October- February) and 12.5 litres/m2 (March-September).
