A study was undertaken to evaluate the effect of farm yard manure, vermicompost and drying methods on flower yield and carotenoid contents in marigold (Tagetes erecta L.) at Instructional farm, Department of Floriculture College of Horticulture and Forestry, Pasighat, Arunachal Pradesh during October 2009 to September 2010. Two varieties viz., Pusa Basanti Gainda and Pusa Narangi Gainda, three levels of nutrition viz., 0 kg ha-1 (control), FYM (25 t ha-1) and vermicompost (10 t ha-1), three levels of drying methods viz., sun drying, ventilated shade drying and hot air oven drying at 500C were used, for investigation. The experiment was laid out in Factorial Randomized Complete Block Design with three replications. Seedlings of marigold cultivars were transplanted in the respective plots under different treatments in the month of November at spacing 30x30cm. Significant response in vegetative and flowering characters in Pusa Basanti Gainda with respect to Pusa Narangi Gainda except carotenoid contents was observed. Highest plant height (47.46cm), more number of flower buds per plant (23.19), increased flower diameter (66.80mm) and dry weight of single flower (1.38g) and enhanced flower yield (204.64 q ha-1) was observed in cultivars Pusa Basanti Gainda. However, maximum plant spread (24.98 cm), advanced flower bud initiation (35.67 days), increased carotenoid content in fresh petals (285.84μg g-1) and dried petals (30.47μg g-1), highest dried petal yield (11.98q ha-1) was noticed in cultivar Pusa Narangi Gainda. Organic manure showed significant response especially well rotten farm yard manure against vermicompost. Flower yield (206.83 q ha-1), carotenoid content in fresh petal (166.04g) and dried petal (16.53g) was responded by farm yard manure, whereas, vermicompost showed maximum dry weight of single flower (1.38g) and dried petal yield (12.83q ha-1).Keywords

A wide array of environment-friendly plant bio-regulators (PBRs) has received attention of researchers in horticulture. Bio-regulators, alternatively known as plant growth regulators (PGR) are natural or synthetic chemicals that affect the expression of biological responses in plant tissues. PBRs are used more extensively in tree fruit production than in any other horticultural or agricultural commodity, and they are essential for effective and profitable production. It plays an important role in growth and development of horticultural crops by sustaining their productivity and improving the quality of produce. The efficient utilization of plant bio-regulators can provide a dramatic change in fruit production despite all success in high density planting and improving quality yield and storage life of the fruits without any spoilage. Different plant bio-regulators like CPPU, salicylic acid, brassinosteroides, strigolactones, jasmonates, etc., have wide scope for exploration and application but are not widely accepted in commercial fruit production despite of their immense usefulness coupled with low hazard to human health.Keywords
