abstract
Arecanut (Areca catechu L.) is an economically important plantation crop extensively cultivated in the humid tropics of India, providing livelihood security to millions of small and marginal farmers. However, productivity often remains below potential due to traditional cultivation practices, imbalanced nutrient management, and inadequate pest and disease control. To address these issues, Frontline Demonstrations (FLDs) were conducted during 2022 at Hirekogaluru village, Channagiri Taluk, Davanagere District under the supervision of ICAR-Taralabalu Krishi Vigyan Kendra. The objective was to assess the impact of improved scientific crop management practices over conventional farmer practices on yield, pest incidence, and profitability. Twenty demonstration plots (0.4 ha each) were established using an improved technology package that included soil test-based integrated nutrient management, green manuring, drainage improvement, integrated pest management, timely irrigation, and moisture conservation measures, while adjacent farmer-managed plots served as checks. Results indicated a substantial improvement in productivity and profitability under demonstration plots. The mean yield increased from 12.26 q ha?¹ (check) to 22.39 q ha?¹ (demonstration), showing an 85.22% gain. Gross returns rose from ?5,49,922 to ?10,07,077 ha?¹, while net returns increased by ?4,57,738 ha?¹. The Benefit-Cost (B:C) ratio improved from 3.49 to 6.42, indicated higher profitability with similar cost of cultivation. The improved package also reduced pest and disease incidence—inflorescence dieback (?52.0%), nut splitting (?50.90%), hidimundige (?35.80%), and spindle bug (?31.80%)—and enhanced inflorescence production by 46.9%. Overall, the study highlights that adoption of the improved technology package significantly enhances yield, income, and resilience in arecanut cultivation. FLDs effectively bridge the technology-yield gap and promote sustainable arecanut production in Karnataka.
