Drone assisted precision agriculture for boosting rice production in lateritic soils of Kerala
Abstract
Lateritic soils being acidic and leached, are often deficient in secondary and micronutrients, limiting crop performance.Addressing these nutrient deficiencies can significantly improve crop yields in these regions. A study was conductedduring 2023-24 and 2024-25 for evaluating the effect of foliar nutrition with drones for enhancement of yield in rice inlateritic rice tract of Ernakulam District. Treatments included soil application of recommended dose of fertilisers (T1), Soiltest based fertiliser application(T2), RDF in soil + liquid Pseudomonas@ 2.5L/ha at 20 DAT using drone (T3), T3+ KAUmultimix Sampoorna @2.5kg/ ha at 30, 50 DAT using drone (T4) and T4 + Potassium nitrate@1.25kg/ha at floweringstage (T5) using drone. Soil application of recommended dose of fertiliser followed by spraying of liquid Pseudomonas@2.5L/ha at 20 DAT, Sampoorna @2.5kg/ha at 30 and 50 DAT and Potassium nitrate @1.25kg/ha at flowering stage usingdrone offered a sustainable option for enhancing yield of rice. Drone technology proved to be a reliable tool for theeffective distribution of foliar nutrients, ensuring uniform coverage and improved nutrient uptake. The findings highlightthe role of advanced nutrient management and drone-assisted precision agriculture in optimizing rice production.
