KVDA produces high quality fruit seedlings in its nurseries located within the Kerio Valley Basin. These projects are duly registered by HCDA.Varieties include : Washington navel, Valencia, Tangerines and Clementine.

Planting Guide

Soil– wide range of soil types (deep, light, loamy and good fertility) pH range 5.0- 7.0

Spacing– recommended spacing is 6m*6m but large trees like Valencia oranges may spaced at 8m*8m

Land preparation: remove all perennial weeds e.g. couch grass. Planting holes must be prepared well before the rains. Holes size must be 60cm×60cm deep. Separate top soil from subsoil during digging and then mix with about two bebes of well decomposed farm manure and 250gm of DAP. Ensure that there is basin around the tree planting to retain water. Fill the hole with manure/top soil mixture firming gently all around the tree roots during planting.

Watering– Is essential for good plant growth and quality fruits. Poor watering leads to small non succulent fruits. About 35 liters of water per week is required per tree.

Pruning– is very essential for healthy plant growth. Prune side shoots growing from the tree trunk below the main branches and on the roots stock should be rubbed off. The height of branching should be allowed at 1m high. Remove dead and broken branches from excessive weight of fruit.

Fertilizer– the following rates of nitrogen fertilizers per tree are recommended:
1st year – 100gms CAN, 2nd year – 250gms CAN, 3rd year – 400gms CAN, 4th year – 550gms CAN and 5th year -500gms CAN
These quantities should be split and applied one or two weeks after onset of the long rains.


Kent– good quality, most popular for export, large long fruit, deep yellow

Apple– good quality, suitable for export, round fruit yellow- orange red.

Baribo– high yielder good quality for export large and long orange red. Suitable for canning.

Ngowe– good quality, most popular for export, a large long fruit deep yellow.

Batawi– good quality, large round fruit, olive green to purple in color.

Altitude– grow best altitude of below 1500m a.s.1 with little variation between day and night temperatures, grow on a rainfall of as little as 650mm per year.

Irrigation– only necessary to see the young trees through the year.

Pruning– 1st year – cap the seedling at 1m high in order to produce a spreading habit (framework).

2nd year– leave 4-5 well spaced branches to be future main ones. No further pruning in the following year.

Transplanting – should be done in the beginning of the rains and spaced at 9m×9m. planting holes should be dug 60cm×60cm. mix in two debes of well rotten farmyard manure and 60gms of DAP with top soil.
