Seed breeders and suppliers provided colourful and informative exhibition stands yet again at Nampo Harvest Day 2007. In this week, we introduce you to some new champions in the field of maize cultivars and other seed varieties. Peter Hittersay did the rounds of suppliers' stands and reports on the new 2007 releases and the claims for each cultivar.
The Maize Information Guide (MIG) 2007 released by the AR CGrain Crop Institute at Nampo is a mine of information. Among other things, it gives the following important guidelines in cultivar planning: Never replace a reliable cultivar with a new or unknown cultivar in a single season. Cultivar variability divides the risk factor. Use a series of cultivars which differ in length of growing season and other characteristics. Cultivars must be adapted to a specific yield potential; however, they should also be able to utilise increased potential conditions and still deliver an acceptable yield at reduced yield potential. Cultivars with wide adaptability can play a role under these conditions. Cultivar choice should be revised annually. It is strongly recommended that farmers consult seed supplier representatives on the suitability of the new cultivars in their production area. For example, in regions that could supply planned ethanol production facilities, farmers may be interested in maize cultivars with high total fermentable (HTF) content. These can yield up to 7% more ethanol than maize with a low HTF.
Yellow Maize AFG 4418 B, AFG 4434 R, AFG 4414:

Lupin Man delup – Narrow Leaf Lupin:
This lupin displays moderate anthracnose resistance and high stem-blight resistance. Its improved aphid resistance means less use of pesticides. It is robust with excellent yield potential and early vigour. The harvest height is superior in low-rainfall areas. Early maturation makes it suitable for crop-topping.
Beans Farah – Faba Bean :
Ascochyta (seedstaining) resistance. This bean shows good yields, similar to Fiesta, and moderate resistance to chocolate spot and rust. Cairo – Faba Bean : High levels of disease and rust resistance characterise this bean cultivar, which is a good fit in a no-till system. This is an early-flowering variety with good yield potential and seed quality.
Fodder and Pasture Crops Nugene – Fodder Oats:

Caprera Crimson – Crimson Clover:
This is a soft-seeded annual clover with a long bright crimson flower head, well adapted to a wide range of soil types though it prefers acid soils. It tolerates clover scorch. It gives multiple grazing, producing large amounts of dry matter. It is a highly nutritious feed with good levels of digestibility. Extended spring production under irrigation is possible and it shows reasonable tolerance to transient waterlogging. It shows excellent recovery from heavy grazing.
Casbah – Biserrula pelecinus:
A midseason variety suitable for intensive pasture crop rotation. It is suited to slightly drier environments with 325mm to 500mm annual rainfall. It is appropriate for fine-textured soils with acidic and alkaline reactions, including sandy loams and clay loams. It has a deep root system and grazing tolerance.
Mauro – Biserrula pelecinus:
This late-maturing variety has lower hardseededness and is better suited to extended pasture phases. It is suitable for use in fine-textured soils with acidic and alkaline reactions, including sandy loams and clay loams, and for regions with 450mm to 700mm annual rainfall.
Vaquero – Cynodon dactylon (Forag e Bermuda grass
): This cultivar provides a broad genetic background for a wide area of adaptation and shows improved resistance to pests and diseases. It provides higher dry-weight yields; improved forage quality, tonnage and persistence; early spring green-up; and improved cold tolerance. It is best as a monoculture and is less expensive to plant, as well as being a great choice for four- to five-week cutting intervals in a hay production programme.
Scimitar – Spineless Burr Medic:
With early- to mid-season maturity and 85 to 90 days to flowering, this adaptable variety is highly productive and grows in a wide range of different soil types. It has an erect growth habit with high herbage and seed production and a high percentage of soft seed (24%). It is suited to temperate areas with a total rainfall of 350mm to 500mm. It can be grazed in the first year of sowing, providing fresh feed in winter and spring and dry feed in summer and autumn. Scimitar is free of leaf diseases but has low resistance to blue-green aphid. It fixes nitrogen, which is valuable for subsequent crop rotations.
