| Popis: | The present investigation was carried out at Regional Horticultural Research Station, ASPEE College of Horticulture and Forestry, Navsari Agricultural University, Navsari during 2019-2020. An experiment consisted of thirteen treatments viz., GA3 (100 and 200 mg l-1), BA (50 and 100 mg l-1), NAA (50 and 100 mg l-1), Novel organic liquid nutrients (1 and 2%), Sea weed extract (1 and 2%), Urea (0.5 and 1%) and control. Above growth substances applied thrice at 3rd, 4th and 5th months after sowing of mango stones. The experiment was laid out in Completely Randomized Design (CRD) and repeated thrice. The results of present investigation revealed that, there was a significant difference on growth of mango seedling due to foliar spray of growth substances at 3rd, 4th and 5th months after sowing of mango stones. Among the different treatments, the maximum the length of the longest root at 8th MAS (52.67 cm), girth of the longest root (2.35 mm), fresh and dry weight of mango seedling (52.97 and 15.67 g, respectively) were recorded in GA3 @ 200 mg l-1 treatment. While, maximum number of roots at 8th MAS (7.47) was noted in BA @ 100 mg l-l treatment. Foliar application of NAA @ 100 mg l-l on mango seedling recorded maximum leaf area at 4th, 5th, 6th, 7th and 8th MAS (56.79, 58.42, 60.62, 62.66 and 65.22 cm2, respectively). While, all the growth characters of mango seedlings were recorded significantly minimum in control. |
