Abstract:
The current investigation “Optimising pinching levels and plant density on flower yield and pot present ability of potted annual – Zinnia elegans” was carried out at College of Horticulture, Rajendranagar, Sri Konda Laxman Telangana State Horticultural University, Hyderabad during December 2021 to February 2022. The experiment was laid out in Factorial Completely Randomized Design with nine treatments and three replications. The main objective of the experiment was to identify the effect of pinching and plant density on flower yield and pot present ability of Zinnia elegans. The treatments consisted of three levels of pinching viz., P1: Single pinching, P2: double pinching and P3: no pinching with three plant density viz., R1: one plant per pot, R2: two plants per pot, and R3: three plants per pot.

The experiment was laid out in Factorial Completely Randomized Design with nine treatments and three replications. The main objective of the experiment was to identify the effect of pinching and plant density on flower yield and pot present ability of Zinnia elegans. The treatments consisted of three levels of pinching viz., P1: Single pinching, P2: double pinching and P3: no pinching with three plant density viz., R1: one plant per pot, R2: two plants per pot, and R3: three plants per pot.
Among different levels of pinching and plant density, no pinch with one plant per pot (P3R1) recorded maximum flower diameter (5.41 cm), Flower longevity (20.25 days), fresh weight of flower per plant (62.92 g) and dry weight of flower per plant (26.12 g) at 30, 60 and 90 DAS respectively. Double pinch with three plants per pot (P2R3) recorded greater value for number of flowers per plant (28.6) and pot present ability (90.07). Interaction effect for some parameters like days to flower bud initiation, days to 50 percent flowering and number of days taken to full bloom were found non-significant.
