Growth characters of marigold (Tagetes Erecta L.) as influenced by integrated nutrient management

The present investigation on periodical observations (30, 60 and 90 DAT) on vegetative growth AT c.s. Azad University of Agriculture and Technology, Kanpur during two consecutive years. The results displayed that all the growth parameters increased to the maximum up to the 75 % nitrogen level with or without biofertilizers. However, maximum plant height was attained with 100% N with or without any combination of biofertilizers. During the second year, effect of biofertilizers was more prominent and promising. As regard the flowering characters there was a significant reduction in days taken to first flower bud initiation and days taken to first flower bud opening under the combined application of bio fertilizers (Azotobacter + PSB) along with 75 % nitrogen in both the experimental years.
