Effect of NPK on plant growth and quality of Lilium (L. A. hybrid Nashville) under polyhouse and open condition

Abstract

The investigation entitled the “Effect of NPK on plant growth and quality of Lilium L.A. hybrid (Nashville) under polyhouse & open condition” A field trial was conducted in the Department of Floriculture and Landscaping, RKVY project at Biotechnology-cum-Tissue Culture Centre, College of Agriculture, OUAT, Bhubaneswar 2015-2016. The experiment was laid out in R.B.D with three replication and seven treatments T1 (Control (FYM mixed to the soil @ 1m3 per 100 m2 area), T2 (Foliar application of NPK 10:10:10 @ 5g/l thrice a week),T3 (Foliar application of NPK 10:10:10 @ 5g/l twice a week), T4 (Foliar application of NPK 10:10:10 @ 5g/l once a week),T5 (Soil drenching with NPK 10:10:10 @ 5g/l thrice a week),T6 (Soil drenching with NPK 10:10:10 @ 5g/l twice a week), T7 (Soil drenching with NPK 10:10:10 @ 5g/l once a week ), Study shows T2 (Foliar application of NPK 10:10:10 @ 5g/l thrice a week) significant effect on growth and quality of Lilium in polyhouse and open condition. In polyhouse T2 (Foliar application of NPK 10:10:10 @ 5g/l thrice a week) was found most suitable in relation to Plant height (34.29cm), Number of leaves per plant (64.68),Plant spread(14.67cm), Spike length (39.73cm),Spike diameter (4.95mm), Flower length (139.30mm), Flower diameter (133.62mm), Bud length (106.21mm) Bud diameter (5.11mm), Days to bud emergence (48.33 days), Number of bud per plant (3.66), Vase life (14.67days) and In open condition Plant height (22.15cm),Number of leaves per plant (55.36), Plant spread (12.68cm),Spike length (29.98cm), Spike diameter (4.14mm),Flower length (145.57mm), Flower diameter (135.36 mm),Bud length (17.45 mm), Bud diameter (2.67mm), Days to bud emergence (38.36 days), Number of bud per plant (2.33),Vase life (10days), Polyhouse provide better growing condition to asiatic lilies with the larger, trumpet-flowering Easter lily, Lilium longiflorum (hybrid Nashville) than open condition under the agro-climatic conditions of Odisha.
