Abstract:

The experiment was conducted with three levels of Irrigation treatments viz., 1.0, 0.8 and 0.6 ER and six levels of fertigation and mulching treatments viz., fertigation of water soluble fertilizers (WSF) @ 100% recommended dose of fertilizers (RDF) with mulching, fertigation of WSF @ 75% RDF with mulching, fertigation of WSF @ 100% RDF without mulching, fertigation of WSF @ 100% RDF without mulching, soil application of normal fertilizers @ 100% RDF with mulching and soil application of normal fertilizers @ 100% RDF without mulching. Among irrigation treatments, 1.0 Evaporation Replenishment (ER) recorded highest values for parameters like plant height (47.98 cm), primary branches (7.73), plant spread (81.17 cm),dry matter production (58.87 g), days to flower bud initiation (34.05 days), duration of flowering (77.74 days), flower diameter (5.57 cm), shelf life (3.56 days), individual flower weight (10.47 g), Flower yield per plant (748.54 g), Flower yield per plot (44.64 kg) and Flower yield per hectare (13.40 tn). 0.8 Evaporation Replenishment (ER) recorded highest values in case of days to 50 % flowering (60.10), Number of flowers per plant (84.83). Among fertigation and mulching treatments, Fertigation with water soluble fertilizers @ 100% RDF and polyethylene mulching recorded highest values for parameters like plant height (51.10 cm), primary branches (8.05), plant spread (89.54 cm), stem girth (10.07 cm), dry matter production (66.21 g), days to flower bud initiation (35.05 days), duration of flowering (77.73 days), flower diameter (5.75 cm), shelf life (4.08 days), Number of flowers per plant (88.08), individual flower weight (11.04 g), flower yield per plant (770.25 g), flower yield per plot (46.72 kg) and Flower yield per hectare (14.01 tn). Among interactions 1.0ER+ Fertigation with water soluble fertilizers @100% RDF and polyethylene mulching recorded highest values for growth, flowering and yield parameters.
