    Sorghum production guidelines for small scale farmers in the Arid Semi-Arid Lands
    (Kenya Agricultural and Livestock Research Organization (KALRO), 2016) Njaimwe, A.; Gachuki, P.; Rono, B.; Mwenda, M.
    Sorghum is an important food security crop in semi-arid lands of Kenya. It is well adapted to semi-arid regions where maize crop often fail to reach physiological maturity in 5 out of 7 cropping seasons due to unreliable and erratic rainfall (Takuji and Baltazar, 2009). In addition, sorghum fits well in popular recipes such as Ugali, uji and can be fermented for porridge or alcoholic beverages (MoA, 2010). The grain has high levels of iron (>70 ppm) and zinc (> 50 ppm), hence may be used to reduce micronutrient malnutrition (Muui et al. 2013). In recognition of their nutrition value and frequent maize crop failures, the Government of Kenya is putting more emphasis on production of indigenous, drought tolerant crops to boost food and nutritional security (MoA, 2010).

    Evaluation of organic and ammendments on Nutrient uptake, phosphorus use effeciency and yield of maize in Kisii region
    (Academic journals, 2014-05-16) Ademba J.S.; Esilaba A,O.; Ngari S.M
    Soil phosphorous and nitrogen are the major constraints to maize production in Nyanza Province of Kenya. The yields are typical of low input systems ranging below 1.0 t ha-1 against a potential of 5.0 t ha-1 per season. This study was conducted at Bototo, Kisii County in Nyanza Province, Kenya, during the long and short rains seasons in 2007. The aim was to determine the effects of phosphatic fertilizers and manure on nutrient uptake, nutrient use efficiency, maize yields and soil nutrients content at harvest. A Randomized Complete Block Design (RCBD) was used with the farms as blocks. Maize H614 hybrid was sown at a spacing of 0.75 × 0.60 m. The plot sizes were 3.75 m by 4.8 m. All plots were top dressed with Calcium ammonium nitrate (CAN) fertilizer at a uniform rate of 30 kg N ha-1. Diammonium Phosphate (DAP), Minjingu Rock Phosphate (MRP) and Triple Super Phosphate (TSP) fertilizers were applied at a rate of 60 kg ha-1 P2O5 (P) and farmyard manure (FYM) at 10 t ha-1. One rate of P at 60 kg ha-1 was applied on all the phosphorus fertilizers and a no P treatment (check) plus lime only treatment was included in determining the effects due to the applied P in the acidic soils. Complete soil chemical analysis was done in all the plots at the planting time. There was significant (p≤ 0.01) crop growth vigour, grain yield, total dry matter, harvest index, nutrient uptake and removal by the crop, available soil P, agronomic phosphorus use efficiency (APUE), physiological P use efficiency (PPUE) due to fertilizers and manure application, with a corresponding reduction in the total soil N, P, K, Ca and Mg. Phosphate fertilizers and manure applications are essential to improve maize yields and nutrient P use efficiency.

    Pearl millet production guidelines for small scale farmers in the Arid Semi-Arid Lands (ASALS)
