Effect of Different Stimulants on Growth, Flowering and Yield of African Marigold (Tagetes erecta L.) cv. Pusa Narangi Gainda

The present investigation was carried out at Floriculture Research Farm, ACHF, NAU, Navsari. The experiment was laid out in Randomized Blocked Design with three replications and nine treatments consisting of two levels of each of Novel organic liquid nutrient @ 0.5 and 1.0 %, Humic acid @ 1.0 and 1.5 %, Panchagavya @ 1.0 and 2.0 %, GA3 @ 50 and 100 mg/l along with control (no spray). The foliar application of novel organic liquid nutrient @ 1.0 % (T2) at 45 and 60 DAT in African marigold significantly influenced vegetative, flowering and yield parameters as compared to other treatments which registered the maximum plant height, more number of branches per plant, highest stem diameter and maximum plant spread in East-West as well as in North-South directions at 70 at DAT. The flowering parameters like maximum duration of flowering (71.33 days), flower diameter (5.85 cm), fresh weight of single flower (9.70 g), longevity (29.27 days), shelf life of flowers (5.47 days), number of flowers per plant (56.47), flower yield (398.24 g/plant, 8.12 kg/plot and 16.92 t/ha) were also recorded under T2. So, it can be concluded that the foliar application of novel organic liquid nutrient @ 1.0 % found better for production as well as quality of African marigold cv. Pusa Narangi Gainda.
