Abstract

A field experiment was conducted on the ffect of integrated nutrient management on African marigold (Tagetes erecta L.) cv. PUSA NARANGI was conducted at Lal baug farm, Department of Horticulture, Junagadh Agricultural University, Junagadh during winter season of two consecutive years i.e. 2011 and 2012. In which 70% RDF + 2 t ha-1 vermicompost + Azotobacter + Azospirillium + PSB significantly improved growth parameters viz., plant height at full bloom stage (115.45 cm), number of primary branches per plant at full bloom stage (28.06). 60% RDF + 3 t ha-1 vermicompost + Azotobacter + Azospirillium + PSB significantly improved flowering parameters viz., the shortest number of days taken to first flower open (53.72 days) and number of picking (9.12) and the shortest number of days taken for 50% flowering (59.50 days). The maximum diameter of flower (7.30 cm) recorded with treatment 70% RDF + 2 t ha-1 vermicompost + Azotobacter + Azospirillium + PSB. The longest duration of flowering (61.14 days), was recorded in 70% RDF + 2 t ha-1 vermicompost + Azospirillium + PSB. The treatment 70% RDF + 2 t ha-1 vermicompost + Azotobacter + Azospirillium + PSB significantly gave higher yield parameters viz., flower yield per plant (376.57) and flower yield per hectare (185.65 qha-1). Quality parameters viz., shelf life of flower was significantly highest (4.95 days) in treatment 200kg N/ha + 100kg P2O5/ha + 100kg K2O/ha + 15 t ha-1 FYM (RDF).

Abstract

The experiment entitled effect of integrated nutrient management on growth and flower yield of chrysanthemum (Chrysanthemum morifolium Ramat.) cv. IIHR-6 was carried out in polyhouse at Department of Horticulture, College of Agriculture, Junagadh Agricultural University, Junagadh during 2011-12. The experiment was laid out in a Completely Randomized Design (CRD) with three repetitions and ten treatment combinations comprising of inorganic fertilizers, organic manures and bio fertilizers. The treatment receiving 75 per cent N + 75 per cent P + 100 per cent K + VC@1.25t/ha + CC@0.875t/ha + Azotobacter @2kg/ha + PSB@2kg/ha recorded the highest plant height, plant spread (NS, EW), number of branches, number of suckers, fresh weight and dry weight accumulation; flowering parameters like early flower bud initiation, first flower opening, 50 per cent flowering and longest flowering duration; yield attributes such as number of flowers per plant, flower weight per plant, and flower yield per ha, quality parameters like stalk length, shelf life of loose flowers, vase life of cut flowers and in situ longevity. Flower diameter was found maximum with the treatment 100 per cent N + 75 per cent P + 100 per cent K + PSB @2kg/ha.
