Understanding interactions and a balance between iron (Fe) and manganese (Mn) as fertilizers is crucial for optimizing tuberose growth. Here, a field experiment considered the effects of various Fe and Mn concentrations on quantitative features, qualitative traits, microelement absorption, and microelement distribution in tuberose plants. The treatments included Fe concentrations of 0, 15, 30, and 45 kg ha-1 along with Mn concentrations of 0, 10, and 20 kg ha-1 from FeSO4 and MnSO4 sources, respectively. According to the results, high Fe concentrations (30 and 45 kg ha-1) negatively affected the uptake of Mn, Zn, and Cu in aerial parts and bulbs. However, an apt combination of Mn and Fe significantly improved several traits. In the first year, Fe (30 kg ha-1) and Mn (20 kg ha-1) significantly increased spike length (27.19%), floret length (46.22%), bulb count (43.60%), vase life (96.08%), and the percentage of opened florets (26.65%). In the second year, Fe (30 kg ha-1) and Mn (20 kg ha-1) resulted in even more improvements, including flower stalk count (78.48%), floret length (47.44%), vase life (32.02%), percentage of opened florets (41.31%), fresh (41.73%) and dry (54.40%) weights of the aerial parts, and bulb fresh (48.98%) and dry (61.54%) weights. The findings highlighted that the combined application of FeSO4 (30 kg ha-1) and MnSO4 (20 kg ha-1) had significantly positive effects on tuberose growth and relevant parameters. Tuberose development improved significantly in response to this combination treatment over the two years, which provides a valuable guideline for farmers and researchers when aiming to enhance tuberose yield.

An experiment was conducted at the Floriculture Research Field of Horticulture Research Centre (HRC), Bangladesh Agricultural Research Institute, Gazipur, Bangladesh during April, 2015 to February, 2017 to find out the suitable planting materials for specific tuberose genotype for growth, flowering and bulb production of tuberose. Individually both genotypes showed better performances for some specific parameters and large bulb showed best results among different planting materials. The genotype TR-001, single variety produced the longer plant and spike (49.37 and 85.04 cm, respectively) and also the heavier stick (72.14 g). Alternatively, TR-004 which is semi-double variety obtained the longer rachis (32.12 cm) and the maximum florets/spike (44.38). In case of bulb and bulblet production, TR-001 produced the heaviest and the largest bulb (19.9 g and 2.89 cm, respectively) while TR-004 produced the maximum bulblets/plant and also the highest bulblet weight/plant (18.39 and 33.88 g, respectively). Considering the nature and size of tuberose bulb, the large bulb demonstrated the longest rachis (33.34 cm), the maximum florets/spike (45.54), the heaviest flower sticks (76.25 g), the maximum number of bulbs/plant (6.70), the heaviest and the largest bulb (22.55 g and 3.12 cm, respectively) and also the maximum number and weight of bulblets/plant (22.55 and 38.53 g, respectively). There were no significant variations among the various combination of tuberose varieties and planting materials on growth, flowering, bulb and bulblet production of tuberose. Besides, mother/old and medium sized bulb showed also statistically similar performances in respect of rachis length, florets/spike, bulbs/plant, weight and diameter of bulb and bulblets/plant. So, mother/old bulb of any tuberose variety can also be used for the commercial production with the large and medium sized bulbs.

Tuberose (Polianthes tuberosa) is one of the most important cut flowers with fragrant buds. To prolong vase life of tuberose, proper preservative solution applying is necessary. For this purpose, two types of chemical and natural treatments were used. Applied treatments were benzyladenine (50, 100, and 150 mg l-1), the extracts of rosemary and Eucalyptus (12, 25 and 50%) and sour orange fruit extract (3, 4, 5 and 6 ml l-1). Sucrose 4% was used in all solutions. Measured characteristics included the vase life, the percentage of opening of the buds, the relative fresh weight, the solution absorption, the total soluble solids, chlorophyll a, b and total chlorophyll. The results showed that the maximum vase life was obtained in benzyladenine treatment of 50 mg l-1 (11.66 days) and the minimum vase life was obtained in the control treatment and rosemary extract of 50% (6.33 days). The highest percentage of buds opening was related to the benzyladenine treatment of 150 mg l-1. The maximum relative fresh weight and solution absorption were obtained in the benzyladenine treatments of 100 and 50 mg l-1, respectively and the maximum amount of total soluble solids was obtained in Eucalyptus extract treatment of 12 %. In addition, the maximum amount of chlorophyll a, b and total was related to the treatment of sour orange fruit extract of 4.5 mg l-1. In general, the results showed that benzyladenine had the maximum vase life but, natural compounds especially the extracts of Eucalyptus and sour orange had the significant effect on the vase life and the other traits of tuberose cut flowers and they can be used as simple, healthy and cheap compounds.
