Effect of Biofertilizers on Vegetative Growth and Flower Yield of African Marigold Tagetes erecta L. c.v Pusa Narangi Gainda

Abstract

Abstract This experiment was conducted to identify the effect of three different biofertilizers and their interaction on flower yield and vegetative growth of African marigold Tagetes erecta L. c.v Pusa Narangi Gainda. The results showed that biofertilizer treatments have been significantly effect on spread plant, plant height, number of leaves/plant number of branches/plant, flower yield/plot number of flowers/plant, flower yield/plant, and flower yield/hectare. The highest values were obtained (107.17cm), (41.67 flowers/plant), (80.12cm), (21.50 branches/plant), (106.17 leaves/plant), (458.83g flower yield/plant), (4129.50g flower yield/plot) and (41.30 flower yield/hectare) respectively by the treatment (T5) with (Azotobacter + Azospirillum+ Mycorrhizae). While the lowest values were obtained (67.69cm), (45.86cm), (10.50 branches/plant), (47.03 leaves/plant), (19.00 flowers/plant), (152.00 g flower yield/plant), (1368.00 g flower yield/plot), and (13.6 flower yield/hectare) respectively by the treatment (T1) with control.
