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.

Abstract

A study was carried out to explore the effect of length of stem and stage of harvest on vase life and display quality of tuberose. As regards stem length, 90 cm stem length (L₄) had longest vase life, maximum uptake of water, minimum loss-uptake ratio, maximum fresh weight and percentage of opened florets, and, lowest percentage of abscised floret; whereas, 60 cm stem length (L₂) enhanced longevity of individual florets. In the case of stage of harvest, significantly high vase life, least loss of water, minimum loss-uptake ratio and lowest physiological loss of weight were recorded in two-florets open stage (S₃). Maximum percentage of opened florets and lowest percentage of abscised florets were observed in three-florets open stage (S₄), whereas, maximum uptake of water and fresh weight of spike were seen in one-floret open stage (S₂). Interaction effect of stem length and harvest stage was also found to be significant showing that 75 cm of stem length with one-floret open stage (L₃S₂) was superior for maximum vase life of spike as well as lowest physiological loss of weight.

Abstract

Field experiments were conducted for three years to assess the performance and select the cultivar ideally suited to Saurashtra region in Gujarat. The cultivars evaluated were Basrai, Harichal, Robusta, Gros Michel, Gandevi Selection and Lacatan. Of these, Gandevi Selection proved superior, with regard to growth parameters, yield characters and its attributes. It also yielded the highest benefit cost ratio.

Abstract

Studies conducted to find out the effect of date of harvesting and floral preservatives on vase life and quality of tuberose cv. Double revealed that among treatments, harvesting on 1^st October (D₈) was better for longer vase life, whereas, 15^th August (D₅) for minimum loss of water, maximum fresh weight of the spike and percentage of opened florets. Similarly, harvesting on 15^th September (D₇) was found better for longest floret longevity as well as loss uptake ratio. In case of floral preservatives, the treatment 500 ppm aluminum sulphate + 4% sucrose (C₆) was found better for longer vase life, maximum uptake of water, lowest loss-uptake ratio and maximum fresh weight of spike, whereas, 400 ppm 8-HQS + 4% sucrose (C₈) for maximum floret longevity and floret circumference as well as maximum percentage of opened and lowest percentage of neck bent florets. The treatment, 50 ppm silver nitrate + 4% sucrose (C₃) exhibited lowest loss of water. In case of interaction effect, 1^st October with 500 ppm aluminum sulphate + 4% sucrose (D₈C₆) was found superior for maximum vase life of spike, highest uptake of water and fresh weight of spike.

Abstract

The study was undertaken to optimize conditions for dry flower production in China aster flowers. The experiment was conducted with eight treatment combinations consisting of two drying conditions viz., room drying (C₁) and sun drying (C₂) and four media viz. Sand (M₁), Sand:Borax (1:1) (M₂), Borax (M₃) and Silicagel (M₄) with factorial concept in completely randomized design. Per cent weight loss and moisture loss were signiflcantly higher under sun drying and silicagel during the entire process of drying from first day to fourth day. Moisture content was higher under room drying and borax from first day to fourth day.

Abstract

A study was carried out to evaluate the role of packing methods on vase life of tuberose. The packing methods in which the spikes wrapped in 200 gauge polyethylene sheet (P₂) were found for longest vase life of spike, maximum uptake of water, lowest loss-uptake ratio, better freshness as well as lowest wilting of florets and highest percentage of opened florets. However, packing method P₂ was found at par with wrapping the spike in metal paper (P₇). Similarly, the poor response was obtained by the packing in craft paper (P₆) and control (P8) in which the bunch of spikes were packed in CCBB without wrapping.
