Red Eye

The variety is particularly suitable for pre-packing. It exhibits no disintegration after cooking and there are no off flavours. Tubers are round oval in shape, white skin with red eye and white flesh. 

Red Eye is a white fleshed potato with characteristic red colouring around the eyes – hence the name Red Eye. It is easily recognisable by consumers and has excellent eating qualities.

This is a high yielding variety with uniform tuber shape and size. Skin texture is smooth and bright, flesh colour is white. Tuber depth is 19 cms; tuber spread is medium. There is no stolon attachment at maturity. Dry matter content is 20%.

Growers Guidelines

The  dormancy period is 2 and a half months and needs to be harvested within this period Red Eye seed sprouts vigourously and it is not necessary to wait for sprouting before planting. Each plant can produce up to 40 tubers, and is capable of producing up to 3kg’s of potatoes per plant.
At a population of 30 000 plants per hectare, this gives a potential yield of ninety tons per hectare. It is therefore not necessary to plant a higher population, but adequate fertililzer must be applied.

Fertilisation guidelines

Ensure that the calcium levels are greater than 70% of the cation exchange capacity or internal brown fleck could be a problem in larges. This can be corrected with lime in acid soils, applied a season before planting, or gypsum can be used.

If Potasssium is below 120 mg/l this should be corrected with KCL or KNO3 before planting.

Planting with 1100 kg 4:3:4 (33) in high potential situations, will supply enough nitrogen for early growth. As tuber initiation is very early the extra Nitrogen at planting is critical.

Red Eye needs a lot of K. At emergence 300 kg 101(36) needs to be applied.  As red eye bulks up early, the plants could suffer from Nitrogen stress resulting in susceptibility to early blight. The response time from application to availability to the plant is generally 2 weeks, and this is why nitrogen needs to be applied early in the growing season. Planting and topdressing (as described here) supplies 188kg Nitrogen and should be sufficient for a 55 ton yield.

A yield potential assessment needs to be done at this stage. For each ton targeted over a 55 ton yield, a further 3kg of Nitrogen needs to be applied. This Nitrogen needs to be applied no later than 40 days after emergence.
