Introduction
In the recent past demand for tomatoes in the region has increased tremendously. This demand can only be met by increasing production area and yield. Better production methods, high-yielding and disease-resistant varieties will play a key role keeping up with the market demand.
Growing Requirements
Tomatoes thrive in well-drained, deep, uniform clay or silty loams. They are very sensitive to water-logged soils and prefer a soil pH of between 6.0 -7.5. They do best in temperatures of between 20°C – 27°C. Tomato production can be adversely affected when the temperatures get below 10°C or exceed 30°C, as fruit setting is affected. When choosing the field ensure tomatoes or a related crop (Solanaceous family) has not been planted in the field for at least 2 years to avoid high diseases presence in the soil.
Choosing a Variety
The various tomato varieties that are available possess different benefits which include high yields, resistance to diseases and long shelf-life. It is up to growers to choose those that will meet needs and are also suited to climate where they are to be grown. No single variety will combine all the best features.

Consider the Following When Choosing a Variety
Resistance to Diseases: Farmers need to select varieties that are resistant to diseases. Varieties that are resistant to Verticillium wilt (Vd), Fusarium wilt (Fol), Fusarium Crown and Root Rot (Fol) Nematodes (N), Alternaria solani (As) and Tomato Yellow Leaf Curl Virus (TYLCV)
Shelf Life: The variety must guarantee that the fruit will remain fresh through the chain and especially during transportation.
Hybrids: Compared to open pollinated varieties (OPVs), hybrids produce higher yields, uniform fruits and possess other preferred quality attributes such as disease resistance and pest tolerance. It is better for the farmer to spend a little more money for Hybrid (F1) seeds but be assured of optimal production.
