Perkerra main findings of the research effort

(Mainly focused on dryland farming)

1. Crops
Early achievements, since 1953 have been successful introduction and evaluations of chilies, onions, Watermelons and Papaya. These have led to the crops being major cash crops at surrounding Irrigation schemes e.g. Kaptombes, Sandai, Losegem, Kapkuikui and Perkerra.
Continued adaptive research of introduced crop varieties at the centre identified crop varieties suitable for irrigated and rainfed farming systems as follows;

1.1 Grain Legumes
Dry beans varieties: Mwezi moja, Katumani bean 1, Katumani bean 9, Kat X-56 and Tepary beans (white), Cowpeas varieties: K80 and M66, Grams varieties: No26 (green) and No 22 (yellow)
Pigeon peas varieties: Kat 60/8, ICPL 87091 and ICPL 87109

2.2 Cereals
Maize varieties: Katumani mpya, Embu composite and Katumani composite B
Fingermillet varieties: P224 and Katumani FM 1
Sorghum varieties: Kari mtama 1, Serena, Seredo and IS 76

1.3 Oilcrops
Groundnuts varieties: Makulu red, Red valencia, ex-Cheplambus and homabay.

1.4 Vegetables
Watermelon varieties: Charleston grey, Sugar baby, Crimson sweet, Haggai, and Odem
Sweet melons varieties: Easy rider and Honey dew
Onions varieties: Red creole, Orient F1 (BGS 71), Tropicana hybrid, BGS95 and Flare F1.

1.5 Fruits
Citrus (oranges): varieties Washington navel and Valencia. Pawpaw variety: solo sunrise. Promising mango varieties: Apple, Kent, Tommy atkins

1.6 Roots and tubers
Cassava varieties: Mucericeri and KME 1
Sweet potatoes varieties: KSP20, KSP 11 and KEMB 10

2. Livestock
2.1. Sahiwal cattle
2.2. Galla goats
2.3. Kenya Dual Purpose Goats (KDPG)
This goat is a product of a 4-way cross between [SEAG x Toggenburg] x [Gala x Anglo Nubian].
2.4. Beekeeping
The centre currently has activities on improved beekeeping using langstroth hives.
2.5. Pasture
On forages, Cenchrus ciliaris pasture grass and bajra/napier hybrid have been found to be particularly suitable for rainfed and irrigated forage production in the ASAL.

3. Soil and Water Management

3.1 Water harvesting for crop production
The tied ridges technique has been tested and found to be more effective in enhancing soil moisture availability for crop growth while the semi-circular hoops have been found to be effective in improving establishment of rangeland pastures.

3.2 Soil fertility
Research done under rainfed conditions in agro-ecological zone UM5 has revealed that the use of farmyard Manure at 4 tons/ha in combination with tied ridges water harvesting technique can give reasonable yield comparable to use of conventional inorganic fertilizers.
