Growth and Yield Response of Maize to Different Nitrogen and Phosphorus Rates in Yola, Nigeria

Kwaghe, E.J.*, Gungula, D

Field studies were conducted during the 2000 and 2001 cropping seasons at the University Research Farm, Federal Universality of Technology, Yola to evaluate the response of maize (New Kaduna White) to different N and P rates in Yola, Nigeria. The study was a factorial type fitted in a Randomized Complete Block Design (RCBD) consisting of 8 treatments replicated three times. The treatments were fou...

Comparative Effect of Groundnut (arachis Hypogea L.) Genotypes on Yield and N Fixation in Sudan and Northern Guinea Savannahs of Nigeria

Terngu Kenneth Moji*, Jibrin Muhammad Jibrin, Umar F. G., Bashir A.Y

Recognition of high yielding and nitrogen (N) fixing groundnut genotypes and desegregating them in the cereal-based cropping systems common in savannah regions will enhance food security and reduce the need for high N fertilizers hence, minimize the high cost and associated environmental consequences. Field trials were conducted during the 2015 growing season at the Research Farms of Bayero Univer...

Effects of Rice Mill Waste and Poultry Manure on Some Soil Chemical Properties and Growth and Yield of Maize

Eneje R. C*, Uzoukwu I

An experiment was conducted at the Michael Okpara University of Agriculture, Umudike Western Farm, to investigate the effect of rice mill waste and poultry manure on some soil chemical properties and growth and yield of maize (Zea mays L.). The study was laid out in a Randomized Complete Block Design (RCBD) with three replicates. Soil amendments were applied at the rates of 0, 2, 4 and 8 t ha-1. T...

Land Use/land Cover Change Detection in Ikwuano Area, Abia State Nigeria Using Landsat Data

Nuga B.O*, Akinbola G. E.

The use of remotely sensed data through Geographic Information System template for land use evaluation and classification is relatively cheap with less drudgery. Landsat satellite imageries covering Ikwuano area were acquired and processed with ERDAS Imagine. These were applied in mapping land use changes in Ikwuano Local Government Area of Abia State, Nigeria. Three major LULC types: forest land,...

Suitability of Urban Waste Land Use in Relation to Heavy Metal and Micronutrient Influence on Soil and Green Amaranth Production in Southeast Nigeria

Ezeifeka A.O*, V. I. Ezeaku, Peter I. Ezeaku, Anikwe M. A. N, Kefas, P. K, Ofem, K.I

An assessment of the impact of long term (>20 years) MSW disposal on soil properties and their suitability for crop productivity was carried out in Anambra and Enugu States of southeast Nigeria. Four dumpsites were selected (two in each state) and, 12 soil auger samples (2 sampling points at 3 depths and 2 repeated measures) each were collected at incremental depth intervals of 0-20, 20-30, and 30...

Some Selected Physical and Chemical Attributes of a Ustalf Under Different Tillage Practices at Dutse, Jigawa State Nigeria.

Nabayi, A.,*, Abubakar Halilu Girei, Suleiman Usman, Abubakar Mustapha Saleh, Haruna, F.D., Nkereuwem, M.E, Santuraki, H.A., Usman M. M

Different tillage practices are being employed by the farmers of Jigawa state, and as such, there is a need to determine its influence on some physical and chemical properties, so that farmers will base their choices on scientific facts rather than assumptions. An experiment was conducted to investigate the effects of three tillage practices (TP) on soil properties in Federal University Dutse, Tea...

Effect of Different Slums on Selected Soil Properties in Abakaliki Southeastern Nigeria

Njoku C.*, Okoro G.C.

A study was conducted at Abakaliki to determine the effect of slums on soil physicochemical properties. Four replicate samples were collected from the four slum locations and control using auger and core for disturbed and undisturbed soil samples, respectively. The soil samples collected were taken to laboratory and analysed for bulk density, total porosity, mean weight diameter, aggregate stabili...

Effect of Different Organic Composts and Inorganic Fertilizer on Nodulation, Nitrogen Fixation and Grain Yields of Soybean (glycine Max L.) Under Field Conditions

Ogunrewo O. M.*, Olayinka A., Taiwo, L. B, Oyedele, O. A

The study assessed the effects of composted corn wastes, poultry droppings and inorganic fertilizer on the number of nodules, nitrogen fixation and grain yields of soybean (Glycine max L.) under field conditions for 2 seasons. The experiments were conducted in the research sub-station of the Institute of Agricultural Research and Training, (IAR&T), Ilora, Oyo State, South Western Nigeria: (Derived...

Effect of Water Depth on Eight Varieties of Rice in Obukiyo, Oju Lga of Benue State, Nigeria

Ogbu O. J,*, Usman, J., Afatar S., Ojowu J.A

Water depth has been described as one of the most important environmental factors determining the growth and yield of rice. Different rice varieties respond differently to various water levels. Three (3) naturally existing water levels (5cm, 10cm and 15cm) at Obukyo Oju Local Government Area of Benue State were studied to evaluate their impact on eight varieties of rice (FARO 15, 37, 44, 52, 57, 6...
