Description The present experiment entitled “Performance of Different Varieties of African Marigold (Tagetes erecta L.) at Different Levels of Nitrogen” was undertaken at college farm of Horticultural College and Research Institute (HCRI), Venkataramannagudem, West Godavari district during Rabi of 2011-2012.
The experiment was carried out with 12 different treatments in a randomized block design (RBD) with factorial concept with three replications. The treatments include three varieties of marigold i.e. Pusa Narangi Gainda, Pusa Basanthi Gainda and V. R. Gudem Local at four levels of nitrogen i.e. control, 150 kg/ha, 300 kg/ha, 450 kg/ha. The data were recorded and statistically analysed to find out the effect of different treatments on the vegetative characters, flower characters, yield parameters, vase life, along with nitrogen uptake in different treatments.
Among the vegetative characters Pusa Basanthi Gainda with the application of 450 kg/ha (T2N3) recorded maximum plant height (77.85 cm). However, highest number of primary (36.87) and secondary (59.92) branches and maximum plant spread (E-W - 62.26 cm N-S - 62.12 cm) was recorded Pusa Narangi Gainda at the same dose of nitrogen (T1N3).
Among the flower characters, Pusa Narangi Gainda has recorded minimum number of days taken for 50 per cent bud initiation (31.10), 50 per cent flowering (42.70) and first picking (42.38) without nitrogen. However the number of flower per plant (82.43), days taken for last picking (130.84), number of pickings (11.49) and the duration of flowering (68.70) were maximum in Pusa Narangi Gainda with 450 kg/ha. On the other hand, flower diameter (9.35 cm) and weight of 100 flowers (2576.31 g) was maximum in Local variety with 450 kg /ha (T3N3).
In case of yield parameters, Pusa Narangi Gainda with 450 kg/ha (T1N3) has recorded maximum yield per plant (1276.61 g), yield per plot (18.54 kg) and yield per hectare (299.48 t).
Maximum shelf life (7.33 days) was recorded in Pusa Narangi Gainda when no nitrogen was applied (T1N0). But nitrogen uptake (320.20 kg) was recorded maximum in the treatment T1N3 i.e. Pusa Narangi Gainda with 450 kg/ha (T1N3).
