IITA and NASC call for greater involvement of private sector in seed yam production
T
op seed production companies from across Nigeria convened at IITA on 6 August to explore novel technologies for high-ratio propagation of seed yam tubers.
IITA scientists working on the Yam Improvement for Income and Food Security in West Africa (YIIFSWA) project have developed novel high ratio propagation technologies such as vine cuttings, aeroponics, and bioreactor to address the constraints of quality, rapidity, and multiplication in seed yam production.
According to Robert Asiedu, IITA’s Director for West Africa, “The unavailability and high cost of high quality seed yam is the primary constraint in West Africa with the food security of about 900 million people heavily dependent on the availability Norbert Maroya briefs seed company representatives visiting IITA. and affordability of seed tubers.” “Seed is one of the most crucial Da Allgreen Seeds Ltd, Bumfash Nigeria Traditionally, farmers use tubers as seeds, elements in the livelihoods of agricultural Ltd, Biocrops Ltd, NASC, all based in which is inefficient and costly. High communities. However, farmers—yam Abuja; Sylva Ejezie Farm Ltd, Asaba, production costs are attributed to the use farmers in particular—are yet to benefit Delta State; Lumiere Seeds Limited, of seed yam tubers, which account for from using quality seed tubers because Premier Seeds Nigeria Limited, Zaria, about 30% of the total yield and as much as of inefficient seed production, and lack Kaduna; Romarey Ventures Limited, Jos; 63% of the total variable cost incurred per of distribution and quality assurance and Samlak Industries Ltd, Ibadan. season of cultivation. Moreover, most of the systems in the country. That is why we tubers are of low quality, containing pests are calling for greater involvement of According to Lava Kumar, head of (nematodes) and pathogens (virus), which the private sector in the establishment IITA’s germplasm health unit, “The new decrease the yield of yam tubers. of a formal seed system with the yam technologies for the production of virusvalue chain,” said Ebenezer Zidafomor, free plants and versatile diagnostic tools for Furthermore, using the traditional system, a representative from the National virus indexing established in the YIIFSWA the multiplication rate in the field is also Agricultural Seed Council (NASC). project are critically contributing to the very low.

The use through projects such as YIIFSWA. of these novel, high-ratio propagation YIIFSWA’s goal is to help stop the decline technologies gives a higher multiplication and double the productivity of yam in the rate that is about 50-100 times more than major producing countries, Ghana and the traditional system.
