Abstract:
The present investigation entitled “Effect of Pinching and Integrated Nutrient Management on Growth and Yield of African Marigold (Tagetes erecta L.) cv. Pusa Narangi Gainda was conducted at Main Experiment Station, Faculty of Agriculture & Science and Technology, Integral University, Lucknow (U.P.) in winter season, during the year 2019-20. The experiment was laid out in Factorial Randomized Block Design with three replications comprising Eight treatment 8 (2 Time pruning and 4 level of fertilizer. First pruning 20 (DAT) & Second during Pruning 30 (DAT). the concept of integrated nutrient management (INM) has emerged as an important tool for maintaining soil fertility and productivity of crops. The mean observations showed that maximum plant height-1 (93.18 cm) was recorded in pinched plant and the minimum plant height-1 (87.55 cm) was recorded in non-pinched plant. The mean table showed that maximum number of leaves per plant (157.60) was recorded in pinched plant and the minimum number of leaves per plant (146.40) was recorded in non-pinched plant. Pinching was found to have significant positive effects on stem diameter in marigold (Tagetes erecta L.) cv. Pusa Narangi Gainda where stem diameter was found to be maximum (1.39 cm) in the pinched plant. Pinching at the visible bud stage is found to improve the plant spread 0.23 cm). The observations on plant height as influenced by integrated nutrient Management and pinching were recorded periodically and the data are given in Table 2. on in marigold (Tagetes erecta L.) cv. Pusa Narangi Gainda.
