Flower and xanthophyll yields of African marigold (Tagetes erecta L.) hybrid L3 as influenced by plant spacing

Investigations were carried out during 2009-2010 to study the influence of plant spacing on flower and xanthophyll yields of African marigold (Tagetes erecta L.) hybrid L3. The experiment was conducted under open field condition with ten treatments replicated thrice. The study revealed that plant spacing significantly influenced the growth, yield and quality parameters and ultimately the cost economic parameters of marigold. Among the spacing treatments, the one which involved a spacing 60 x 30 cm with 75 cm pathway between every six rows accommodating 55, 555 plants/ha proved superior in all respects. This treatment recorded the highest values for flower yield (662.29 g/plant), estimated flower yield (36.79 t/ha), xanthophyll content (1.60 mg/kg of fresh flowers), estimated xanthophyll recovery (58.87 kg/ha), net returns (Rs. 93, 876/ha) and BCR (2.13). The control which involved a spacing of 75 x 22.5 cm accommodating 59, 045 plants/ha recorded an estimated flower yield of 27.93 t/ha, xanthophyll content of 1.38 mg/kg of fresh flowers and a BCR of 1.38.
