During the year 2019-20 crop was taken as fresh, while during 2020-21 all the observations were recorded on ratoon crop. Two individual experiments were laid out. In first experiment three time of planting (March, April & May) and six genotypes (Pearl Double, Hyderabad Double, Mexican Single, Prajwal, Suvasini & Vaibhav) were taken, while in second experiment two harvesting stage of florets (Bud burst stage & Fullbloom stage), three planting time and six genotypes were selected. Both the experiments were laid out in randomized block design with three replications. The observations were recorded on various growth, flowerings and bulb yield parameters. The Statistical analysis of data of first experiment revealed that better results in terms of growth, flowering, spike yield and bulb yield of tuberose were found in Mexican Single followed by Prajwal when planted in March, while in second experiment highest absolute was recovered from May planted Prajwal genotype when harvested at bud-burst stage during both the years.EnglishThesis
