Influence of levels of fertigation and sources of nutrients on flowering and yield characters of marigold (Tagetes erecta L.) CV. pusa Narangi Gainda

Abstract

The experiment on marigold was conducted to study the optimum dose of fertigation in marigold using fertilizers from different sources on flowering and yield characters of marigold cv. Pusa Narangi Gainda grown under open conditions. The experiment was laid out in Randomized block design (RBD) with seven treatments. The results indicated significant difference among the treatments with respect to flower quality and yield. Application of 75% of recommended dose of fertilizers (RDF) in water soluble form (WSF) promoted maximum number of flowers per plant, flower yield per plant and flower yield per hectare (14.42 t) in addition the flower diameter and flower weight also were maximum. Further, the benefit cost ratio was also maximum (2.10) with the application of 75 per cent of RDF with WSF in marigold cultivated under open conditions.
