This book presents a comprehensive scientific analysis of agrometeorological parameters influencing the growth, yield, and quality of key plantation crops in Kerala, including coconut, cashew, coffee, tea, rubber, cardamom, cocoa, and black pepper.It investigates the complex interactions between altitude, temperature, rainfall, humidity, solar radiation, and wind dynamics, and their roles in shaping crop phenology, productivity, and spatial distribution. The work further addresses climate-induced stresses, seasonal variability, and the implications of extreme weather events on plantation ecosystems. Emphasis is placed on region-specific agrometeorological assessments, sustainable crop management strategies, and the integration of mixed cropping systems for climate resilience. Incorporating empirical research data, long-term climatological observations, and adaptive cultivation models, this publication serves as a critical reference for researchers, academicians, and professionals engaged in agrometeorology, plantation science, and climate-resilient agriculture.
