White Hybrid Maize - CAP9021

All round performer CAP 9021 is a high yielding hybrid which performs well in high potential regions. This hybrid has done well as a silage variety. It has been noted to have grain yields of over 10mt/ha as the norm. Silage yield potential of between 75-80mt/ha under ideal conditions.

It has flinty grain type with excellent milling quality too. It also has good resistance to Grey Leaf Spot, ear rot and rust. This variety is medium maturing North of 26 latitude and becomes late maturing to the South of that, where it is mainly used for silage. CAP 9021 has a tall plant structure and generally produces one large ear.

  • Medium to late maturity- plant early

  • Semi-flint, large kernels

  • Tall and leafy plant structure

  • Resistant to most foliar diseases

  • Recommended plant population 48 000 plants/ha

We recommenced it for 1A, 2A, and 3A for grain and region 4 for silage.



Farmers all over the KwaZulu-Natal Midlands have been reporting outstanding results with Capstone Seeds’ White Hybrid Maize variety CAP 9021. Jason Shewan from Grassy Park Dairy in Nottingham Road planted a few hectares of the cultivar in order to test it, he was happy to admit that it stood head-and-shoulders above the rest.

In the area that Jason is farming, there is severe pressure from diseases and CAP 9021 was hardly affected while the variety from another competitor - sitting just next to it in the field - was severely damaged by Grey Leaf Spot and more. Francis Yeatman predicted that Jason was going to be able to yield 65 - 70mt/ha of silage material.

James Kean was blown away with the way that CAP 9021 bounced back after heavy hail damage early on after planting. The hail caused the plant to lose about 40% of its leaf material and was still able to yield impressive silage results after he thought that he was going to have to plough it all in.
