Abstract:
During the winter seasons of 2020-21 and 2021-22, a field experiment was conducted on the “Effect of integrated nutrient management on vegetative growth and flowering of African marigold (Tagetes erecta L.) cv. Pusa Narangi Gainda)”. Three biofertilizers (Azotobacter, Azospirillum and PSB) were used in the treatments, as well as three levels of vermicompost (2.0, 3.0 and 4.0 t ha^-1) and three levels of NPK (75, 60 and 45 percent of RDF). When compared to control, application of 60% RDF + 3 tonne/ha Vermicompost + Azotobacter + Azospirillium + PSB (T₈) resulted in maximum plant height, number of primary branches per plant, length of primary branches (cm), number of secondary branches, plant spread (cm) in (North-South) direction, plant spread (cm) in (East-West) direction, number of leaves, fresh weight of plant (g) and dry weight of plant (g). When compared to control, the application of 60 percent RDF + 3 tonne ha^-1 Vermicompost + Azotobacter + Azospirillium + PSB (T₈) recorded a minimum number of days for days to bud initiation, days to open first flower, number of days taken for 50 percent flowering and flowering duration.
