Zambia: SC 303 is an ultra-early-maturing white maize variety that reaches maturity in approximately 90-110 days. It produces white, semi-flint grain and has a yield potential of 5-6 tonnes per hectare, equivalent to approximately 100-130 × 50 kg bags. SC 303 has tolerance to Grey Leaf Spot, Northern Corn Leaf Spot, Maize Streak Virus and maize stalk rots. It has moderate tolerance to Diplodia ear rots, very good drought tolerance and very good standability. Its recommended use is primarily summer grain production.
DRC: SC 303: An ultra early maturing variety (90-110 days) with white, semi flint grain and a potential yield of 6.5 tonnes per hectare. The brochure reports tolerance to grey leaf spot, northern corn leaf blight, maize streak virus, stalk rot, and ear rot caused by Diplodia and Fusarium. It rates drought tolerance and standability as very good. SC 303 is intended for rainy season grain production and is listed for all zones.
Zimbabwe: SC 303 – Ultra-Early Maturing Maize Hybrid: SC 303 is an ultra-early maize hybrid with strong heat and drought adaptation. It reaches physiological maturity in approximately 96-110 days, depending on altitude, and has demonstrated a yield potential of up to 11.7 tonnes per hectare. Its short crop duration makes it suitable for maize-wheat rotation systems. It is particularly suited to marginal production zones with low rainfall and short rainy seasons, making it an important option where the available growing period is limited.
Mozambique: SC 303 is an ultra-early maize hybrid in the supplied Mozambique brochure. It has a yield potential of up to 12 tonnes per hectare under a good season at approximately 50,000-55,000 plants per hectare and reaches physiological maturity in less than 110 days.
