Finger Millet (Eleusine coracana) Fodder Yield Potential and Nutritive Value under Different Levels of Phosphorus in Rainfed Conditions

Wekha N. Wafula, Moses Siambi, Henry Ojulong, Nicholas Korir & Joseph Gweyi-Onyango · Journal of Agriculture and Ecology Research International · 2017

Scarcity of fodder is the major limiting factor for increasing livestock production in Kenya. With rising energy costs and declining water levels in the semi-arid tropics and sub-tropics, crops that use less water like finger millet could become an alternate fodder crop. The fodd...

Nitrogen and Phosphorus Uptake and Partitioning in Finger Millet as Influenced by Phosphorus Fertilization

Wekha N. Wafula, Nicholas K. Korir, Henry F. Ojulong, Moses Siambi & Joseph P. Gweyi-Onyango · Journal of Experimental Agriculture International · 2016

Finger millet (Eleusine coracana) production in Eastern Africa remains low due to a variety of factors including soil nutrient depletion. As intensive row-crop production evolves, improvements in managing soil nutrient quantity and availability of less renewable nutrients like P...

Open access Research Article 10.9734/JEAI/2016/30151

Phosphorus Influence on Plant Tissue Nitrogen Contents and Yield Attributes of Finger Millet Varieties in Semi-arid Region of Kenya

Wekha N. Wafula, Nicholas K. Korir, Henry F. Ojulong, Moses Siambi & Joseph P. Gweyi-Onyango · International Journal of Plant & Soil Science · 2016

The experiment was conducted with the aim of evaluating the effect of differential levels of P on finger millet accumulation of N and yield components. On-station experiments were conducted at the KALRO-Kiboko crops research station in Makueni County during the short and long rai...

Effect of Phosphate Levels on Soil Rhizosphere Nutrient Balances and Finger Millet Yield

Wekha N. Wafula, Nicholas K. Korir, Henry F. Ojulong & Joseph P. Gweyi-Onyango · Asian Research Journal of Agriculture · 2016

Soil infertility is one of the main factors leading to low finger millet production in the semi-arid tropics of Kenya. About 50-80% of P applied as fertilizer is adsorbed by soil and the amount of P needed to achieve maintenance of its adequate status and influence on other soil...

Effect of Biofertilizer on Growth and Yield Characteristics of Zea mays L. in Different Ecological Zones in Kenya

Ashmitha S. Kumar, Wekha N. Wafula & Nicholas K. Korir · Asian Journal of Soil Science and Plant Nutrition · 2019

In order to reduce the dependence on chemical fertilizers, alternative methods should be developed which will provide nutrients to plants. The increased cost of inorganic fertilizers, including their inability to condition the soil and their polluting effect on the environment, h...

Influence of Calcium, Potassium and Watering Regimes on Blossom End Rot in Two Varieties of Tomato (Solanum lycopersicum) in Mandera County, Kenya

Mulyungi P. Syengo, Wekha N. Wafula, Ntinyari Winnie, Nicholas K. Korir & Joseph Gweyi-Onyango · Journal of Agriculture and Ecology Research International · 2019

Blossom end rot (BER) is one of the physiological disorders of economic importance in tomato farming since it significantly reduces yield and thus affects profit margins. Most tomato disorders are due to mineral deficiencies and unbalanced nutrition. Improving the supply of speci...

Effect of Phosphorus Levels on Soil Properties and Plant Tissues of Two Nerica Varieties

Etabo E. Mathew, Wekha N. Wafula, Nicholas K. Korir & J. P. Gweyi-Onyango · Asian Soil Research Journal · 2018

Phosphorus levels in the soil are easily fixed and rendered unavailable to plants even if they are found to be high and therefore, its influence on uptake of other nutrients such as nitrogen, and potassium cannot be overemphasized. In that view, an experiment was set out at KALRO...

Interaction Effect of Growth Regulators and Irrigation Schedules on Growth and Yield of French Beans in Kiambu County, Kenya

Ikiba L. Kalawa, Wekha N. Wafula, Nicholas K. Korir & Joseph Gweyi-Onyango · Asian Journal of Research in Crop Science · 2018

Inadequate and unreliable rainfall distribution in Kenya has affected negatively agricultural yields and family incomes. Integration of growth regulators can stimulate favorable crop growth under limited moisture, but there has been scarce research and documentation on them. Ther...
