Effect of Foliar Application of Cultar and NAA on Marigold (Tagetes erecta L.) cv. Basanti Local

Both plant growth regulators had great influence on vegetative and reproductive attributes of marigold. The effect of Cultar was more pronounced over NAA in reducing growth. NAA impact was more on vegetative attributes to that of Cultar. Flowering was greater with NAA to cultar. Plant height was maximum (66.36 cm) in 400 ppm NAA and minimum (38.49cm) in cultar 35 ppm while, the maximum branches per plant (17.51) were observed in C2N3 and least (10.02) in C3. Similarly, minimum and maximum values for leaves/plant (101.01 and 172.32), roots / plant (10.25 and 16.14) and tap root length (18.25 cm and 25.22cm) were recorded in C3 and C2 N3, respectively. From date to transplanting time taken for blooming was minimum (58.45 days) with 35 ppm Cultar C3, and maximum (83.45 days) in N3. Bloom-flowers/plant (16.23) in C3 and 30.42 in C2N3), non-bloom flower/plant (3.05 in C2 N3 and 9.63 in C3 ), flower diameter (3.01 in control and 5.96 in C2N3 ), flower size (22.22 cm2 in control & 28.56 cm2 in C2 N3), bloom-flower fresh weight (7.06 g in control and 9.73 g in C2N3) and bloom-flower dry weight (1.95g in control and 2.51g in C2N3) were also minimum and maximum values for the parameters, respectively.
