Abstract

Marigold is a very common and a hardy flower crop cultivated throughout the world. Pinching is an important intercultural practice commonly followed in cultivation of marigold however, this needs to be standardized for getting higher yields in commercial cultivation. Hence, the present investigation was conducted at Rajasthan Agricultural Research Institute, Durgapura, Jaipur, Division of Horticulture, during 2020-21 and 2021-22 to standardize the commercial pinching practice for getting higher productivity. Three levels of pinching (no pinching, single at 20 days and double at 20 and 40 days after transplanting) were used in the course of the research arranged using a factorial randomized block layout with three replications applied to African marigold variety Pusa Narangi Gainda. The results revealed that treatment P0 (No pinching) was discovered to be the finest in increment in height of plant, early flower bud initiation flower opening and treatment P2 (Double pinching) in boosting spread of plant, primary branches, length of leaf, leaf width, leaf area, plant fresh weight, plant dry weight, total biomass, root- shoot ratio, 50% flowering, flower diameter, stalk and ray floret length, fresh and dry flower weight, mass and number of flower per plant, flower yield additionally improved quality characteristics like chlorophyll and xanthophyll content in marigold. Hence, it might be concluded that application of double pinching can be helpful and recommended in improving yield as well as quality characteristics in commercial cultivation of marigold.
