Influence of Organic and Inorganic Inputs on Vegetative, Flowering and Yield Attributes of Marigold cv. Pusa Narangi Gainda

Abstract

The present investigation was carried out on “Influence of organic and inorganic inputs on vegetative, flowering and yield attributes of marigold cv. Pusa NarangiGainda” at instructional farm, Department of Floriculture and Landscape Architecture, College of Horticulture and Forestry, Pasighat, Arunachal Pradesh during the year 2021-22. A field experiment was laid out in Randomized Block Design (RBD) with 13 treatments in three replications. Findings revealed significant (p<0.05) influence of organic and inorganic inputs on vegetative, flowering and yield characters of the marigold. Maximum plant height (130.70 cm), number of primary branches (11.20), number of secondary branches (14.40), leaf area (56.57 cm2), East-Westplant spread (49.25 cm), and North-South plant spread (46.50 cm) were associated with treatments T12-FYM @ 25 t.ha-1 + Vermicompost @ 5 t.ha-1 + Mustard oil cake @ 5 t.ha-1 + Dolomite @ 222 kg.ha-1. Treatment T12 also had earlier bud initiation (44.10 days), maximum number of flowers per plant (20.23), and flower yield (159.73 q). However, the maximum flower diameter (62.19 mm) was recorded in the treatment T10 - FYM @ 25 t.ha-1 + Mustard oil cake @ 5 t.ha-1 + Dolomite @ 222 kg.ha-1. The study demonstrates that combination of organic inputs significantly enhances the vegetative, flowering and yield attributes in marigold that could be exploited for increased productivity of the crop.
