The study conducted by Mangalayatan University and Bharti Vidyapeeth’s College of Horticulture, India, reviewed the impacts of climate change on guava (Psidium guajava L.) production and explored adaptive strategies for sustaining its yield and quality. Guava, an economically important tropical fruit valued for its high nutritional and medicinal properties, is increasingly vulnerable to environmental fluctuations caused by climate change.
The study identified major stressors such as rising greenhouse gas levels, erratic rainfall, prolonged droughts, and temperature extremes, all of which negatively influence guava’s flowering, fruit set, and maturation. These climatic disruptions lead to reduced yields, irregular blooming, and lower fruit quality, affecting traits like pulp-to-seed ratio, sweetness, vitamin C concentration, and antioxidant content. The research also highlighted the critical role of pollinators, noting that honey bee activity can enhance guava fruit set by 20–40%, though pollinator populations are themselves declining under climate stress.
To mitigate these challenges, the study emphasized integrated adaptive practices including precision irrigation, mulching, canopy management, and crop diversification. It also underscored the importance of developing heat- and drought-tolerant guava varieties through genetic and biotechnological approaches. Overall, the review called for a combination of modern technology and traditional horticultural methods to maintain guava productivity under changing climate conditions.
