In the face of rising climate variability, population growth, and shifting agro-ecological challenges, ensuring sustainable and profitable horticultural production is a national priority. This book, Agro-Advisory Services in Horticulture, provides a comprehensive and science-based exploration of how real-time, location-specific advisories can support fruit and spice crop growers across Indias diverse agro-climatic zones.The book compiles contributions from leading scientists, extension specialists, and agronomists who have worked extensively in the field of horticulture. It emphasizes the importance of agro-advisory systems as a bridge between research and field-level application, particularly for small and marginal farmers facing the impacts of climate extremes.Topics include canopy management, insect and disease control, nutrient scheduling, harvesting and post-harvest protocols, and ICT-based mobile advisory systems. Specific focus is placed on subtropical fruit crops like mango, guava, and citrus, as well as spice crops such as cardamom, turmeric, and black pepper. Region-specific case studies, including those from Maharashtra, Kerala, and saline-sodic zones, offer actionable insights into field-level impacts and adaptive management practices.The book also highlights the critical role of women in horticultural sustainability, the significance of farmer engagement through micro-level advisories, and the necessity of resource conservation practices for long-term productivity.This publication is an invaluable resource for: Extension professionals involved in agri-communication Researchers and academicians in horticulture and climate-resilient agriculture Students of agricultural sciences Policy planners and development agencies aiming to strengthen farmer support systems By combining scientific knowledge with field-tested advisory models, the book aims to empower Indias horticulture sector to thrive amidst both environmental and market challenges.
