Evaluation of existing groundnut genotypes for nitrogen fixation may be useful as selection criteria for high nitrogen fixation thereby minimizing the high cost of inorganic fertilizer and its associated environmental consequences. The objectives of this study were to determine symbiotic nitrogen fixation and contribution to soil nitrogen by groun... Continue Reading
This research focuses on the effects of concretionary nodules on nutrient composition of a Plinthic Haplustalf, and the effects of concretionary nodules on phosphate fractions and adsorption by the soils. Soil samples were collected from five farmers field in Biye northern guinea savannah,Nigeria, the soils collected were further designated as Biye... Continue Reading
Phosphorus deficiency is a major constraint that limits food production in Nigeria, especially under acidic soil conditions. Presently, successful production of high nutrient requiring crops such as maize is only possible with the use of inorganic phosphate fertilizers which are very costly and often unavailable to the farmer. In an attempt to addr... Continue Reading
Soil quality protection under intensive land use and fast growing economic development has become a major challenge for sustainable resource use in developing countries such as Nigeria. Continue Reading
The broad objective of this study was to examine the structure, performance and efficiency of plantain marketing system in FCT Abuja and to determine its profitability. Data for this study were collected using well-structured questionnaire. Three Area Councils and 20 markets were purposively selected for the study using systematic random sampling. ...

Groundnut (Arachis hypogeaa L.) productivity in Nigeria has remained low over the years due to the inherent low fertility status of the soils of the savanna,a region where it is mostly grown by small holder farmers with limited imputs. Groundnut can fix atmospheric nitrogen through symbiotic association with native rhizobia but unfortunately, the a... Continue Reading
The study focused onanalyzing women empowerment through production of ginger for household food security in Southern Kaduna. Two Local Government Areas were purposively selected in Southern Kaduna and six villages were randomly selected from these Local Government Area and 224 farmers were selected in this study area. Primary data were collected f... Continue Reading
Sunflower is an important oilseed crop due to its health related values. Induced mutations are often used to create new genetic variability where sufficient variation does not exist naturally as in the case of sunflower. This study was carried out at the laboratory and research farm of the Institute for Agricultural Research (IAR), Samaru, Zaria to... Continue Reading
Germplasm diversity analysis and characterization provides the foundation for crop improvement programme. This work has used morphologicaland molecular tools to study diversityand characterizeMoringa oleifera. Continue Reading
A study was conducted to evaluate the effect of inclusion level and feeding regime of Ficus sycomorus leaf meal on the growth performance, nutrients digestibility, nitrogen balance and rumen metabolites of Yankasa rams. A total of 36 rams weighing on the average 15.39kg were randomly assigned to four diets, containing 0%, 5%, 10%, and 15% inclusion... Continue Reading
The Study herein reported involves the evaluation of the dairy potential of Bunaji, Bokoloji (Sokoto Gudali) breeds on dairy productive traits in which a total of 3105 records of 761 cows over a period of 24 years were used. The records on birth weight were 3647 for the two breeds. The investigation also included the study on the environmental fact... Continue Reading
This study investigated the impact of cassava market participation on farmer‘s economic efficiency and poverty level in Maigana agricultural zone, Kaduna state, Nigeria. A multi-stage sampling technique was used to collect primary data with the aid of a structured questionnaire from 150 cassava farmers from two major cassava producing Local Gove... Continue Reading
Experiments were carried out between 2009 and 2013 in the Biotechnology laboratory, Department of Plant Science, Ahmadu Bello University Samaru, Zaria with the aim of developing tissue culture regeneration, cryopreservation and slow growth protocols for conservation of groundnut. Embryonic axes obtained from seeds of Four (4) groundnut varieties; (... Continue Reading
This thesis observed evolutionary relationships, compare the effectiveness of mitochondrial DNA (cytochrome oxidase b gene) among some species of poultry, 30 birds per breeds or species (Rhode Island Red, Rhode Island White, Shikabrown, Francolins, Guinea Fowls and Japanese Quails) using mitochondrial DNA`s cytochrome b oxidase gene and chicken mic...

Two experiments were carried out to determine the nutritive value of sorghum, millet, cassava and sweet potato with or without enzyme supplementation in broiler chickens production. The growth performance, nutrient digestibility, heamatological parameters and characteristics of broiler chickens were evaluated. In the experiment 1, diets were not s... Continue Reading
