The present experiment was conducted out during the 2022-2023 at the Horticulture Research Farm, Department of Horticulture, Sam Higginbottom University of Agriculture, Technology and Science Prayagraj. The banana tissue culture cv. Grand Naine G-9 (Cavendish Subgroup, AAA) was brought from government tissues culture, unit Lucknow. Tissue culture plants were left in shade nets condition for 2 weeks due to transportation and environmental stress. Light and frequent irrigation with watering can was done accordingly with respect to moisture levels in the soil. The field experiment was set up in RBD with 9 treatments and three replications. The different levels of Magnesium viz., (75g and 150g /plant) and Calcium viz., (150g and 300 g/plant).Based on the findings of the experiment, it is concluded that RDN + Calcium (150g /plant) showed the highest plant height (3.29 m), plant girth (72.14 cm), number of leaves/plant (27.11), number of sucker at harvest (9.13), leaf area  (10.19 m2), length of inflorescence (122.62 cm), days taken to flowering (281.77), days to taken fruit harvest (83.12), bunch weight (27.28 kg), no. of hands/bunch (10.80), No. of finger per hand (17.33),total number finger of bunch (187.31), finger weight (136.33 g), finger length  (22.87 cm), finger girth (15.20 cm), fruit yield per plant (25.52 kg), TSS (23.48 °Brix), Vitamin C (13.48 mg/100g), carbohydrates (25.44 g/100g), calcium  (10.38 mg/100g) and magnesium (40.38 mg/100g).

The present investigation was carried out in the Department of Horticulture, Sam Higginbottom University of Agriculture Technology and Sciences, Prayagraj in August 2022 to December 2022. The experiment was conducted to evaluate the best IBA concentrations among different concentrations of IBA for producing best layering and survival percentage in Olive. The experiment was laid out in Randomized Block Design having 8 treatments and replicated 3 times. The treatment T4 in which IBA 4000 ppm was applied for air layering was found to be best in terms of shoot and root parameters observed, i.e., Number of days to root formation (46.11), Number of roots per layer (7.33), Root length (6.73 cm), Root thickness (1.66 mm), Number of new sprouts (2.67-1MAP, 3.89-2MAP & 5.67-3MAP), length of new shoot (2.78cm-1MAP, 3.73cm-2MAP & 5.44cm-3MAP), Number of new leaves (7.22-1MAP, 10.78-2MAP & 16.56-3MAP) and survival percentage (50.89%) in air layered olive plants, whereas minimum values were recorded in T8 (control). It can be inferred from this study that, the use of IBA 4000 ppm was effective to produce better root and shoot parameters and successful establishment of air layers in olive.
