    Response of Maize to Organic and Inorganic Sources of Nutrients in Acid Soils of Kenya 

    Kisinyo, Peter; Opala, P. A.; Nyambati, R.O. (2015-07-21)
    aize yield in Kericho County, Kenya is limited by infertile acidic soils. The effect of inorganic sources of nutrients and amendments; triple superphosphate (TSP), calcium ammonium nitrate (CAN) and lime, were compared ...

    Comparison of soil phosphorous extraction by Olsen and double acid methods in acid soils of Western Kenya 

    Maghanga, K. Justin; Kituyi, L. John; Segor, K Fred; Kisinyo, Peter (2015-08-21)
    hosphorous is an essential nutrient in plants required for root establishment. In the soil, it is applied as DAP, TSP or phosphate rocks. In acid soils, aluminium and iron are dominant and tend to “fix” phosphorous, ...

    Maize Response to Micro Dose Inorganic Inputs on an Acid Smallholder Farm in Kenyan Lower Midland 

    Palapala, Valerie; Kisinyo, Peter (Pearl Research Journals, 2016-09-13)
    The study determined nitrogen, phosphorus fertilizers and lime micro doses effects on soil chemistry and maize performance on an acid soil smallholder farm. Treatments were micro doses (50% of recommendations) of N (0 and ...

    Influence of Cropping System and Residue Management on Selected Soil Chemical Properties 

    Kisinyo, Peter (Advances in Research., 2018-02-09)
    Declining soil fertility in sub-Saharan Africa caused by continuous cropping without nutrient inputs has resulted in declining crop yield. The study was aimed to determine the effects of crop rotation and crop residue ...

    Effects of lime, phosphorus and rhizobia on Sesbania sesban performance in a Western Kenyan acid soil 

    Kisinyo, Peter; Othieno, Caleb; Gudu, Samuel; Okalebo, J. R.; Opala, P. A.; Maghanga, J. K.; Agalo, Jerry; Ng'etich, W. K.; Kisinyo, Joyce; Osiyo, R. J.; Nekesa, A. O.; Makatiani, E. T.; Odee, D. W.; Ogola, B. O. (2015-07-21)
    Aluminium (Al) toxicity, phosphorus (P) deficiency and low rhizobia populations limit Sesbania (Sesbania sesban) performance in tropical acid soils. The study determined the i) indigenous rhizobia populations that nodulate ...

    Effect of organic and inorganic phosphorus sources on maize yields in an acid soil in western Kenya 

    Kisinyo, Peter; Opala, P. A.; Okalebo, Æ J. R.; Othieno, Caleb (Research Gate, 2009-06-20)
    Maize production in western Kenya is commonly limited by P deficiencies and aluminum phytotoxicity. Due to high costs of imported fertilizers and lime, focus is now shifting to solutions that utilize local resources. We ...

    Response of Sorghum (Sorghum bicolor (L.) Munch) and Chemical Characteristics of Soil to Organic and Inorganic Fertilizers on Kenyan Lower Midlands Acid Soil 

    Kisinyo, Peter; Opala, P. A.; Gudu, Samuel (International Journal of Plant & Soil Science, 2019-05-17)
    Soil acidity, low level of nitrogen (N), phosphorus (P) and soil organic matter are major constraints to sorghum production in Kenya. We investigated the effect of farmyard manure (FYM) and combined application of inorganic ...

    Phosphorus Sorption and Lime Requirements of Maize Growing Acid Soils of Kenya 

    Kisinyo, Peter; Othieno, Caleb; Gudu, Samuel; Okalebo, J. R.; Opala, P. A.; Maghanga, J. K.; Ng'etich, W. K.; Agalo, Joyce; Opile, R.W.; Kisinyo, Joyce; Ogola, B. O. (2015-08-21)
    In Kenya, maize (Zea mays L.) is mainly grown on acid soils in high rainfall areas. These soils are known for low available phosphorus (P), partly due to its sorption by aluminium (Al) and iron oxides. The study ...
