Effect of Co-applied Corncob Biochar with Farmyard Manure and NPK Fertilizer on Tropical Soil
Aporia, Samuel Obeng; Byalebeka, John; Murongo, Marius; Ssekandi, Joseph; Noel, Gordon Logura (Science Direct, 2021-09)Biochar has shown a positive impact on degraded soils. However, the effect of co-applied biochar with farmyard manure and inorganic fertilizer on soil chemical characteristics, yield, nutrient constituent and economic ... -
Effect of sisal (Agave Sisalana) and sweet thorn (Acacia Karroo) ethno-medicinal extracts on prevalence of selected pests and diseases in assila F1 tomato Variety
Maganda, Farouk; Acero, Miria; Byalebeka, John; Ssekandi, Joseph; Murongo, Marius Fabian (Ecological Organic Agriculture - Growing Sustainability, 2023-03-30)Introduction - This study compared the efficacy of sisal (Agave sisalana) and sweet thorn (Acacia karroo)ethno-medicinal extracts on prevalence of selected pests and diseases in Assila F1 tomato variety was carried out ... -
Low cost maize stover biochar as an alternative to inorganic fertilizer for improvement of soil chemical properties, growth and yield of tomatoes on degraded soil of Northern Uganda
Wacal, Cosmas; Basalirwa, Daniel; Byalebeka, John; Tsubo, Mitsuri; Nishihara, Eiji (Springer Nature, 2023-10-07)Soil fertility decline due to nutrient mining coupled with low inorganic fertilizer usage is a major cause of low crop yields across sub-Saharan Africa. Recently, biochar potential to improve soil fertility has gained ... -
Low Input Approaches for Soil Fertility Management in Semiarid Eastern Uganda
Kaizzi, C. Kayuki; Byalebeka, John; Wortmann, S. Charles; Mamo, Martha (American Society of Agronomy, 2007)Grain sorghum [Sorghum bicolor (L.) Moench] is an important food crop of semiarid sub-Saharan Africa. Crop yields are generally low, partly due to low soil fertility. Research was conducted with farmers to evaluate, ... -
Maize Response to Fertilizer and Nitrogen Use Efficiency in Uganda
Kaizzi, C. Kayuki; Byalebeka, John; Semalulu, Onesmus; Alou, Isaac; Zimwanguyizza, Williams; Nansamba, Angella; Musinguzi, Patrick; Ebanyat, Peter; Hyuha, Theodore; Wortmann, S. Charles (American Society of Agronomy, 2012)Maize (Zea mays L.) is an important smallholder crop in Uganda. Yields are low because of low soil fertility and little fertilizer use. Yield response to nutrient application and economically optimal rates (EOxR, where x ... -
Moringa Oleifera Seeds as a Low-cost Biosorbent for Removing Heavy Metals from Waste Water
Obeng Apori, Samuel; Atiah, Kofi; Hanyabui, Emmanuel; Byalebeka, John (University PIM, Banja Luka, 2020-05)Heavy metals are considered to be one of the major contaminants of water in recent years due to their non-biodegradable property; hence making them toxic and bioaccumulate to living organisms. ... -
Optimizing Smallholder Returns to Fertilizer Use: Bean, Soybean and Groundnut
Byalebeka, John; Kayuki, Kaizzi C.; Semalulu, Onesmus; Alou, Isaac Newton; Zimwanguyizza, Williams; Nansamba, Angella; Odama, Emmanuel; Musinguzi, Patrick; Ebanyat, Peter; Hyuha, Theodore; Kasharu, Appollo K.; Wortmann, Charles S. (2011)Smallholder African farmers commonly lack the financial means to purchase enough fertilizer for application at the economical optimal rates (EOR), or the rates for maximization of net returns ha−1, to all of their land. ... -
Phosphorus Sorption in Tropical Soils
Hanyabui, Emmanuel; Obeng Apori, Samuel; Agyei Frimpong, Kwame; Atiah, Kofi; Abindaw, Thomas; Ali, Muhammed; Yeboah Asiamah, Joshua; Byalebeka, John (AIMS Press, 2020-09)Phosphorus is an important primary nutrient required by plants in large quantities. The various forms of P that plants can take up are the primary monobasic phosphate ion (H2PO4−), secondary dibasic phosphate ion ... -
Potential of Termite Mounds and its Surrounding Soils as Soil Amendments in Smallholder Farms in Central Uganda
Obeng Apori, Samuel; Murongo, Marius; Hanyabui, Emmanuel; Atiah, Kofi; Byalebeka, John (BMC Research Notes, 2020)The low fertility of highly weathered soils has been a major problem for resource-constrained small-holder farmers. In central Uganda, smallholder farmers have been collecting termite mound soils anywhere around the termite ... -
Roles for Herbaceous and Grain Legumes, Kraal Manure, and Inorganic Fertilizers for Soil Fertility Management in Eastern Ugand
Byalebeka, John; Kaizzi, K. C.; Wortman, C. S.; Mamo, M. (Springer, 2011)Grain sorghum [Sorghum bicolor (L.) Moenich] is an important food crop in semi-arid areas of sub-Saharan Africa. Crop yields are generally low and declining partly due to low soil fertility. Therefore on-farm research was ... -
Sorghum Response to Fertilizer and Nitrogen Use Efficiency in Uganda
Kaizzi, C. Kayuki; Byalebeka, John; Semaluluo, Onesmus; Alou, Isaac; Zimwanguyizza, Williams; Nansamba, Angella; Musinguzi, Patrick; Ebanyat, Peter; Hyuha, Theodore; Wortmann, S. Charles (American Society of Agronomy, 2012)Sorghum [Sorghum bicolor (L.) Moench] is important for smallholder production in semiarid parts of Uganda. Grain yields are low because of low soil fertility. Little fertilizer is used. Yield response to N, P, and K ...
