dc.description.abstractThe investigation entitled “Studies on nutrition scheduling through drip irrigation for quality flower production in chrysanthemum (Chrysanthemum morifolium Ramat.)” was carried out experiment during the year in 2020 at the research farm of Department of Floriculture and Landscaping, Punjab Agricultural University, Ludhiana, Punjab with aim to study the effect of NPK through drip fertigation on vegetative and floral growth of chrysanthemum on the spray variety ‘Punjab shaymli’ with five treatment combination viz, T1 NPK @ 100:150:100 kg/ha (100%RDF) i.e. 33.3: 33.3: 33.3% NPK (vegetative phase), 33.3: 33.3:33.3% NPK (bud phase), 33.3f: 33.3: 33.3% NPK (flowering phase).T2 NPK @ 100:150:100 kg/ha (100%RDF) i.e. 40:20:20% NPK (vegetative phase), 30:40:40% NPK (bud phase), 30:40:40% NPK (flowering phase).T3 NPK @75:112.5:75 kg/ha (75%RDF) i.e.33.3: 33.3: 33.3% NPK (vegetative phase), 33.3: 33.3:33.3% NPK (bud phase), 33.3: 33.3: 33.3% NPK (flowering phase).T4 NPK @75:112.5:75 kg/ha (75%RDF) i.e. 40:20:20% NPK (vegetative phase), 30:40:40% NPK (bud phase), 30:40:40% NPK (flowering phase), T5 100% RDF, N:P2O5:K2O (100:150:100) kg/ha as soil application (control). Full dose of P and K as basal, N three equal split-first applied as basal, second dose at pinching and third dose one month after pinching. The experiment was laid out in Randomized Block Design having four replications. Data on vegetative growth and floral attributes was recorded and statistically analysed. The treatment T2 (NPK @ 100:150:100 kg/ha/year) resulted in maximum plant height (73.06 cm), plant spread (18.49 cm), chlorophyll content (91.28cci), leaf area (32.68 cm2), length of spray (68.06 cm), stem girth (8.56 mm), flower diameter (4.87cm), minimum days to bud appearance (71.42 days), days to colour shown (82.17 days), days to 50% flowering (98.42 days), number of spray/plant (4.67), number of spray/ha (154110), number of flowers/plant (46.58), duration of flowering (37.50 days), vase life (21.67 days) and benefit cost ratio (3.29) as compared to other treatments. Based on the study, it can be concluded that NPK @ 100:150:100 kg/ha (100%RDF) i.e. 40:20:20% NPK (vegetative phase), 30:40:40% NPK (bud phase), 30:40:40% NPK (flowering phase) was found to be best combination for the production of best quality flower in chrysanthemum.
