A field trail was conducted to study the effect of different levels of growth promoters and retardants on growth and flower yield of different cultivars of African marigold. Two PGR’s namely Gibberellins (GA3) and Cycocel (CCC) were taken as growth promoter and growth retardant, respectively. Two cultivars namely Pusa Narangi Gainda and Pusa Basanti Gainda were taken to evaluate their suitability in Chhattisgarh. The result indicated that the growth and flower yield were significantly influenced by different plant growth regulators and cultivars. The maximum plant height was recorded with cv. Pusa Basanti Gainda as compared to cv. Pusa Narangi Gainda. While, maximum number of primary and secondary branches was recorded with cv. (V1) Pusa Narangi Gainda. Among the growth regulators treatments GA3 300 ppm (25 DAT) + GA3 300 ppm (45 DAT) recorded maximum plant height. However, maximum number of primary and secondary branches, number of flowers, fresh weight of flowers per plant and flower yield ha-1 was noticed with treatment GA3 300 ppm (25 DAT) + CCC 1500 ppm (45 DAT). The pooled analysis of two year data also indicated that the general cost of marigold cultivation was (59750.00 Rs. ha-1) per hectare including labour cost, cost of various inputs and over head costs. The highest gross returns (236620.00 Rs. ha-1), net returns (159595.00 Rs. ha-1) and highest benefit: cost ratio (3.20) was found in the treatment (GA3 300ppm + CCC 1500ppm) whereas the lowest (151020.00 Rs. ha-1) was observed in control.
