Abstract:
Jeevamrutha application in mango var. Alphonso at different concentrations and at different frequent intervals was carried out on 20-year-old mango var. Alphonso at Regional Horticulture Research and Extension Centre, Dharwad (University of Horticultural Sciences, Bagalkot) during 2019-20 and 2020-21. The objective to standardize the dose and frequency of jeevamrutha application in mango. Growth parameters were found to be increased by increasing the jeevamrutha concentration at a very frequent interval. In pooled data, the total chlorophyll content in leaf was found to be maximum due to application of jeevamrutha 1000 litre/ha at an interval of 15 days (D₃F₁) (4.12 mg/g) was on par with D₂F₁ (3.83 mg/g) and D₁F₂ (3.65 mg/g). Number of fruits per tree and fruit yield varied significantly. The pooled data revealed that RPP recorded the maximum number of fruits (330.00) and fruit yield (78.64 kg/tree and 9.71 t/ha) followed by application of jeevamrutha 1000 litre/ha at an interval of 15 days (D₃F₁) (226.50, 56.98 kg/tree and 7.04 t/ha for number of fruits per tree, fruit yield (kg/tree) and fruit yield (t/ha) respectively). Shelf life was found to be maximum in D₃F₁ (12.91 days).
