Effect of bio-regulators on flowering behavior and yield attributes of African marigold (Tagetes erecta L.) cv. Pusa Narangi Gainda

Abstract

The present investigation entitled “Effect of bio-regulators on flowering behavior and yield attributes of African Marigold (Tagetes erecta L.)” was carried out at Horticultural Research Centre (HRC) of Sardar Vallabhbhai Patel University of Agriculture and Technology Modipuram, Meerut, Uttar Pradesh during the year 2016-2017. The layout of experimental field was laid down in Randomized Block Design in which ten treatments along with 3 replications. The Maximum days taken to first bud initiation were recorded application of Ethrel 400 ppm (T10), days taken to opening of first flower was recorded with MH 400 ppm (T7), duration of flowering (50.76 days) was recorded with GA3 300 ppm (T4), length of flower stalk was recorded with application of GA3 300 ppm (T4), Maximum number of flowers per plant was recorded with the application of GA3 300 ppm (T4), flowers diameter was recorded with the application of GA3 300 ppm (T4), number of flowers per plant was recorded with the application of GA3 300 ppm (T4), weight of flower was recorded with the application of GA3 300 ppm (T4), Maximum flower yield per plant was recorded with the application of GA3 300 ppm (T4), maximum flower yield per hectare was recorded with the application of GA3 300 ppm (T4).It is recommended to farmers for commercial cultivation of African marigold (Tagets erecta L.) cv. Pusa Narangi Gainda.
