When addressing micronutrient deficiencies in Kerala soil, paddy farmers exhibited reluctance in supplying micronutrients via foliar sprays due to labor inadequacy and the imposition of additional labour charges. In response, Krishi Vigyan Kendra Palakkad initiated frontline demonstrations involving foliar micronutrient sprays for paddy clusters, exploring the possibilities of UAV based spraying. Kollengode block of Palakkad, being one among the highest in area and production of paddy in the district was purposively selected for the demonstration. UAV based micronutrient application was conducted in 25 acres of Vazhappuzha and Mamani padasekharams. Farmers had reported the increase in yield and reduced time taken for spraying compared to manual spraying. Also raised the concerns about high spraying cost. Subsequent research to assess the readiness of these paddy farmers towards UAV-based spraying was conducted within the padasekharams. Fifty-five farmers of two padasekharams who experienced drone spraying in their paddy field were selected as respondents. Primary data was collected using semi-structured interview schedule. The framework of Technology Readiness Index (TRI 1.0) developed by Parasuraman et al. (2000) with suitable modifications was adopted in the study. Readiness was measured using four dimensions, i.e., optimism, innovativeness, discomfort, and insecurity. Respondents were categorized based on technology readiness segmentation as pioneers (16%), explorers (31%), hesitators (32.7%), avoiders (18%) and skeptics (2%). Farmer groups highlighted significant constraints associated with the use of drone-based fertilizer applications in paddy, citing the high cost of spraying, limited awareness of its benefits, inadequate technical support from extension agencies, lack of subsidies and unavailability of timely services.
