Abstract
A field investigation entitled " Effect of different propagation media on rooting of marigold cuttings and it’s field performance " was carried out during the years 2016-17 and 2017-18 at Floriculture Unit, Department of Horticulture, Dr. PDKV, Akola with the objectives to study the effect of different propagation media on rooting of cutting, growth, flowering, yield and quality of marigold and to find out suitable propagation media for higher and better quality flower production of marigold.
The experiment was laid out in Randomized Block Design with three replications. The treatments comprised of twelve different propagating medias viz. soil, sand, vermicompost, FYM, cocopeat, soil + sand (1:1), soil+ vermicompost (1:1), soil + FYM (1:1), sand + vermicompost (1:1), sand + FYM (1:1), soil + sand + vermicompost (1::1:1) and soil + sand + FYM (1:1:1).
The result of the present investigation indicated that, significantly minimum days to callusing, maximum roots plant-1, root length as well as leaf area of marigold cuttings were recorded with the vermicompost media. Whereas, significantly minimum days to rooting, maximum rooting success, leaves plant-1 were recorded under the cocopeat media.
Performance of transplanted marigold plants in respect of growth parameters viz. plant height, leaves plant-1, branches plant-1, weight of fresh biomass as well as leaf area were noticed significantly maximum in the plants obtained from the vermicompost media. Whereas, maximum plant spread was noted under the plants obtained from cocopeat media.
Similarly, significantly minimum days for emergence of first flower bud, 50 per cent flowering, days to first harvesting and maximum blooming period of marigold were observed in the plants obtained from vermicompost media.
Flower yield in respect of weight of flowers plant-1, number of flowers plant-1, flower yield plant-1, plot-1 and ha-1 were harvested significantly maximum in the plants obtained from vermicompost media.
Flower quality parameters viz, diameter of fully opened flower, weight of petals flower-1,shelf life and vase life of flower were found to be the best with vermicompost media. However, longevity of intact flower was noted maximum under the cocopeat media.
In economic analysis, the vermicompost media recorded maximum B:C ratio.
