Response of Integrated Nutrient Management on Vegetative and Flowering Characters of Marigold (Tagetes erecta L.)

The present investigation was under taken on periodical observations (30, 60 and 90 DAT) on vegetative growth at C.S. Azad University of Agriculture and Technology, Kanpur. Results indicated that all the growth parameters such as number of leaves, plant spread, diameter of plant stem, increased to the maximum upto the 75 % nitrogen level with or without biofertilizers. 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 biofertilizers (Azotobacter + PSB) alongwith 75 % nitrogen (T8) in both the years. While, Application of 100 % nitrogen alongwith biofertilizer inoculation delayed both the parameters. However, the maximum days were required under control (T14).
