Performance of Lisianthus (Eustoma grandiflorum) varieties for growth, yield and quality parameters under naturally ventilated polyhouse

Abstract

The current study, titled “Evaluation of Lisianthus (Eustoma grandiflorum) for growth, yield and quality parameters under naturally ventilated polyhouse”, was carried out at Horticulture Research and Extension Centre, Kanabargi, Belagavi, during 2024. The experiment was conducted in a Randomized Complete Block Design with nine varieties replicated three times to assess growth, yield and quality parameters under naturally ventilated polyhouse. The variety Rosita 3 Clear Pink exhibited superior vegetative performance with maximum plant height, number of leaves, stem girth, plant spread (E-W and N-S), leaf length, width, area and area index and number of branches. Rosita 3 Clear Pink recorded minimum number of days to flower bud initiation and days taken for bud to flower opening. Aube 4 Pure White attained the peak flower diameter. In terms of yield Rosita 3 Clear Pink exhibited the maximum spike count per plant, gross and net returns and the highest B:C ratio, followed by Rosita 3 Pink Picotee.
