dc.description.abstractABSTRACT The present investigation entitled, “Effect of drip irrigation levels on growth and flowering of alstroemeria (Alstroemeria hybrida L.) was carried out under naturally ventilated polyhouse at the Experimental Farm of Department of Floriculture and Landscape Architecture, Dr Y S Parmar University of Horticulture and Forestry, Nauni, Solan, (HP) during 2014-15 and 2015-16. The experiment comprised of ten irrigation treatments viz., T 1 = Surface irrigation (October- September), T 2 = 4 litres/m 2 (October- September), T 3 = 6 litres/m 2 (October- September), T 4 = 8 litres/m 2 (October-September), T 5 = 10 litres/m 2 (October- September), T 6 = Surface irrigation (Oct- Feb) and 125% surface irrigation (March- September), T 7 = 4 litres/m 2 (Oct- Feb) and 5 litres/m 2 (March-September), T 8 = 6 litres/m 2 (Oct- Feb) and 7.5 litres/m 2 (March-September), T 9 = 8 litres/m 2 (Oct- Feb) and 10 litres/m 2 (March-September) and T 10 = 10 litres/m 2 (Oct- Feb) and 12.5 litres/m 2 (MarchSeptember), respectively. The experiment was laid out in a randomized complete block design and each treatment was replicated thrice. The data were recorded on various hydrothermal regimes and physico-chemical properties of growing medium as well as growth, flowering and yield parameters of alstroemeria cv. ‘Capri’ for two consecutive years. The results revealed that treatment T 10 was found to be most successful in the moderation of hydrothermal regimes of growing medium besides ensuring higher availability of NPK content. The said treatment also recorded maximum values for available nitrogen (398.97 kg ha -1 ), available phosphorus (61.14 kg ha -1 ), available potassium (253.23 kg ha -1 ), plant height (97.23 cm), stem length (92.25 cm), stem thickness (8.45 mm), number of shoots per plant (46.21), number of leaves per stem (41.26), number of flowers per stem (17.95), number of flowers per cyme (5.69), inflorescence diameter (9.28 cm), vase life (20.28 days), yield per plant (43.18 cut stems), yield per plot (172.72 cut stems), marketable yield per plot (164.08 cut stems), more benefit : cost ratio (2.97:1) as well as earliest flowering (93.58 days) except water use efficiency (0.34 cut stems m -2 l -1 ) which was recorded to be more in T 4 i.e. 8 litres/m 2 (October-September). As regards the effect of flushes, 1 st flush recorded maximum values for plant height (110.66 cm), stem length (106.27 cm), stem thickness (7.67 mm), number of shoots per plant (50.87), number of leaves per stem (42.74), number of flowers per stem (17.20), number of flowers per cyme (4.72), inflorescence diameter (8.75 cm), vase life (17.19 days), yield per plant (43.80 cut stems), yield per plot (175.16 cut stems) and marketable yield per plot (148.24 cut stems) except earliest flowering ( 57.14 days) and water use efficiency (0.32 cut stems m -2 l -1 ) which was recorded to be more during 2 nd flush. The interactive effects of treatments and flushes revealed that maximum values w.r.t. plant height (121.47 cm), stem length (115.92 cm), stem thickness (8.59 mm), number of leaves per stem (47.78), number of shoots per plant (61.66), early flowering (132.46 days), number of flowers per stem (21.83), number of flowers per cyme (6.27), inflorescence size (9.77 cm), vase life (21.09 days), yield per plant (57.62 cut stems) and yield per plot (230.47 cut stems), marketable yield per plot (218.95 cut stems) were recorded in the interaction T 10 ×B1 i.e. when plants were irrigated with T10 i.e. 10 litres/m 2 (Oct- Feb) and 12.5 litres/m 2 (March-September) during 1 st flush. Therefore, it is concluded that the application of water @ 10 litres/m 2 (October- February) and 12.5 litres/m 2 (March-September) applied through drip twice a week had been successful in moderation of requisite hydrothermal regimes and ensuring higher availability of NPK in growing medium and finally improved the growth, flowering and marketable yield of cut flowers including benefit: cost ratio of alstroemeria cv, ‘Capri’.en_US
