“…Additionally, inhibition of peroxidase activity by humic acid could contribute to this effect by preventing auxin breakdown, in line with findings by Muscolo et al (1993) [6] and Aghera et al (2019) [1] . Moreover, improved nutrient uptake-particularly of gibberellin-like compounds found in humic acid-may be responsible for the greatest blossom diameter (11.75) seen in the RDF + Humic acid treatment.…”

Roses are the most popular flower in the floriculture sector globally because of their remarkable quality and quantity. They are used for cut flower production, yard beautification, and pot plant growing, among other things. Jharkhand has a burgeoning floriculture industry that grows five commercial varieties of roses, gladiolus, gerberas, marigolds, and Chrysanthemums in open fields. In Jharkhand, there are over 1.20 lakh hectares planted with flowers; the industry is expanding. (Database NHB, 2021). But since the green revolution, there are serious ecological and environmental concerns associated with the extensive use of chemical pesticides and fertilisers. There is a movement in favour of organic agricultural methods to address this problem. As a possible addition to mineral fertilisers, biostimulants have gained popularity since they may increase crop quality and production. The effects of several biostimulants in conjunction with recommended fertiliser dosages (RDF) on the development and flowering of Mainu Parle rose cultivars were evaluated through an experiment. Out of all the therapies that were tried, RDF with humic acid (T3) showed some significant results. The maximum plant height (86.50 cm), highest leaf count (104.68), highest number of flowering shoots per plant (11.40), longest shoot length at first flower bud appearance (34.38 cm), highest number of flowers per plant (28.20), and largest flower diameter (11.75 cm) were all displayed by plants treated with RDF + humic acid. These results demonstrate how humic acid may be used as a helpful biostimulant in rose culture, providing encouraging opportunities to increase growth and flower output while lowering dependency on chemical inputs.

Effect of Fertilization and Planting Date on the Production and Shelf Life of Tuberose

et al. 2023

The tuberose, Agave amica, is an ornamental plant appreciated for its oils. The objective of this study was to evaluate the effect of planting dates (April, May and June), dose of NPK (N80-P60-K40, N300-P200-K200, N100-P50-K50 and N00-P00-K00), and fertilizer sources (chemical, organic, combined and control) on tuberose production, flower quality and postharvest shelf life. The physiological variables spike characteristics, leaf color, biomass, and postharvest flower quality were evaluated. The results show that the best planting date is in June; plants planted in June flowered earlier (156 days) and had better flower quality. The fertilization formula N300-P200-K200 produced a higher number of spikes (1.32) and flowers (38.93), a larger stem diameter (0.9 cm), and promoted fewer days to flowering (188d). Plants fertilized with chemical fertilizer had fewer yellow leaves, a larger number of spikes (1.41), a longer spike length (26.89 cm), and a higher number of flowers/spikes (39.28), corms/plants (31.03), and open flowers on the ninth day in vase (13.14) and heavier stems with spikes (134.80 g). In conclusion, the dose of N300-P200-K200 from chemical source and planting in June produced the best flower quality and the shortest production cycle.
