How to Revive Old Mango Trees That Have Stopped Fruiting Without Cutting Them Down Agricultural scientists in Rohtas have advised reviving old and low-yielding mango trees through scientific methods rather than cutting them down. Proper pruning, balanced organic and chemical fertilizers, and pest management can successfully restore their productivity. According to Dr. Ratan Kumar, a scientist at the Krishi Vigyan Kendra in Bikramganj, Rohtas, the presence of dry, weak, diseased, and unnecessary branches on old mango trees negatively impacts their overall productivity. By undertaking a scientific rejuvenation process for such trees, their ability to bear fruit can be significantly restored to a large extent. Pruning and Protective Treatment The first step in this rejuvenation procedure involves cutting away the old, dry, damaged, and redundant branches of the tree. Subsequently, a paste of copper oxychloride is applied to the cut surfaces to minimize the risk of fungal infections. To control potential pest and disease infestations, a solution of imidacloprid 17.8 percent EC should be prepared at a rate of approximately 1 milliliter per liter of water and sprayed over the plants. Organic Manure and Seasonal Timing Dr. Ratan Kumar notes that the monsoon season is considered the ideal time for the rejuvenation of old mango orchards. During this period, along with pruning the branches, providing adequate organic manure and essential nutrients to the trees is crucial. He explained that the quantity of compost should be determined according to the age of the plant, where applying about 1 kg for a one-year-old plant, 2 kg for a two-year-old plant, and around 10 kg for trees aged 10 years or more proves beneficial. Application of Chemical Fertilizers About a month after applying the compost, it is also necessary to provide essential chemical fertilizers to the trees. According to Dr. Ratan Kumar, determining the exact amounts of urea, DAP, and potash based on the age and size of the plant is appropriate. For instance, a quantity of about 100 grams of urea, 75 grams of DAP, and 60 grams of potash is recommended for a one-year-old plant. As the tree grows older, the nutrient quantities can be increased in the same proportion, though for large and old trees, the actual quantity is best decided based on soil testing, the tree condition, and advice from a local agricultural expert. Comprehensive Orchard Management Experts emphasize that instead of merely providing water and manure, it is essential to combine proper branch pruning, pest and disease management, and balanced nutrition simultaneously for old mango trees. Adopting this procedure at the right time encourages new branches to sprout and enhances the productivity potential of the orchard. Saving Old Orchards from Felling Therefore, if the trees in your mango orchard are many years old and their fruit yields have declined, there is no need to cut them down assuming they are useless. Through scientific rejuvenation, old orchards can be made green and productive once again. What this means for you This guidance is extremely valuable for all farmers and orchard owners who possess old mango groves and are facing financial losses due to declining fruit yields. • Across India: Mango-growing farmers throughout the country can rejuvenate old trees using this scientific method instead of chopping them down, achieving better fruit production at a lower cost without waiting years for new saplings to mature. • In Rohtas: Orchard owners in Rohtas and surrounding rural regions can follow this expert advice from agricultural scientists to make their old and unproductive groves economically profitable once again, thereby improving their incomes. • Cost and Savings: Instead of paying to cut down trees and planting new ones, farmers can obtain high-quality fruit from established mature trunks by spending minimal amounts on pruning, manure, and plant protection. • Time Efficiency: New mango saplings take several years to become fruit-bearing, whereas the rejuvenation process allows mature trees to start yielding production again in a much shorter span. • Proper Maintenance: Adopting the correct proportions of fertilizers and manures also preserves soil health and keeps the trees free from diseases. Why this happened The decline in productivity of old mango trees is primarily caused by the accumulation of diseased branches and nutrient deficiencies over time. There are clear agricultural reasons why performing scientific rejuvenation is necessary. • Impact of Weak Branches: When dry, diseased, and redundant branches remain on trees for a long time, the plant's energy is wasted, halting the development of new fruit-bearing parts. • Risk of Fungal Infection: Cutting large branches leaves open wounds prone to fungal attacks, which makes the application of protective pastes like copper oxychloride scientifically mandatory. • Age-Based Nutrition: As trees age, their capacity to draw nutrients from the soil changes, which is why specific quantities of compost and fertilizers are designated for plants aged one, two, or ten years and above. • Favorable Monsoon Timing: During the rainy season, moisture and favorable temperatures prompt new branches and shoots to sprout very rapidly, making it the most ideal time for rejuvenation. Questions & Answers 1. Why does the productivity of old mango trees decrease? The fruit-bearing capacity is affected due to the accumulation of dry, weak, diseased, and unnecessary branches on old trees. 2. What substance is applied to the cut branches of the tree? A paste of copper oxychloride is applied to the cut parts to minimize the possibility of fungal infection. 3. Which chemical should be sprayed for protection against pests and diseases? A solution of imidacloprid 17.8 percent EC should be sprayed at a rate of about 1 milliliter per liter of water. 4. Which season is considered best for the rejuvenation of old mango orchards? The monsoon season is considered the most suitable time for rejuvenating old mango orchards. 5. How much compost should be given to a tree aged 10 years or more? Applying about 10 kg of compost is useful for trees that are 10 years old or older. 6. What is the recommended quantity of chemical fertilizer for a one-year-old plant? About 100 grams of urea, 75 grams of DAP, and 60 grams of potash are specified for a one-year-old plant. https://trendkia.com/en/business/rohatasa-ke-vaijnanikon-ne-bataya-purane-ama-ke-peron-ko-bina-kate-dobara-kaise-karen-hara-bhara-aura-phaladara-29834 TrendKia — Har trend, sabse pehle.
