Maize hybrid seed provides farmers with varieties containing improved genetics, such as high yield potential and unique trait combinations to counter diseases and adverse growing conditions. However, the quality of hybrid seed depends greatly on field production methods, both in adherence to quality assurance standards and implementation of appropriate agronomic management, coupled with favourable weather conditions. Due to unpredictable weather patterns, Seed Co released varieties that combine high yield with a low duration. These are varieties such as SC301, SC303, SC419, SC529. Furthermore these top left hybrids allow the farmer practise double cropping.
