Review on the Production Constraints of Locally Cultivated Pumpkin (Cucurbita spp.) in Kenya

Abstract

Cucurbita, commonly known as pumpkins, are a group of versatile and economically significant plants cultivated worldwide. In Kenya, pumpkins play a crucial role in the agricultural sector due to their versatility, serving a wide range of purposes, including food consumption, medicinal applications, and livestock feed. However, the cultivation of pumpkins in the country faces various challenges, impacting productivity and limiting its potential for growth. The purpose of this review was to explore the challenges encountered by Kenyan farmers in pumpkin production. A comprehensive understanding of these constraints is essential for formulating effective strategies to enhance pumpkin cultivation and uplift the livelihoods of farmers in the area. Extensive searches were performed on Scopus, Web of Science, and Google Scholar to gather scientific articles, technical reports, and government documents related to Cucurbita in Kenya. Pumpkin (Cucurbita spp.) production in Kenya faces numerous constraints, including disease, pests, negative connotations towards pumpkins, unpredictable weather conditions, modern civilization, chlorosis, development of small, unmarketable, and low-priced fruits, fruit rotting, fruit and flower abortion, a lack of genetic variation, post-harvest losses and high transport costs. Limited research exists on challenges faced by pumpkin farmers outside of Central and Western Kenya. The study recommends conducting more extensive research, including diverse agro-ecological zones like Eastern, Rift Valley, Coastal, and Northern regions, to gain a holistic understanding of production constraints throughout the country. The study further suggests promoting research on disease and pest management, raising awareness to overcome negative perceptions, improving market access and infrastructure, facilitating knowledge transfer, and creating value addition opportunities for pumpkin products. Implementing these recommendations will sustain pumpkin production and maximize benefits for Kenyan farmers and consumers.
