Rice Response to Nitrogen Fertilizer on Three Wetland Soils in Ado - Ekiti, Nigeria

FASINA Abayomi Sunday, Shittu O.S.*, Amoloja O.

Field experiment was conducted on three wetland soils during the 2011 late growing season at Ekiti State University Teaching and Research Farm to investigate the response of wetland rice to four rates of N (0, ST, 100 and 150 kg N/ha). The results obtained from the study showed that, nitrogen fertilizer application had significant (P

Profile Characteristics of Selected Rice - Producing Soils of Abia State in South - Eastern Nigeria

AHUKAEMERE C.M.*, Ndukwu, B., Ihem, E.E, Onwuso, G.I.

Due to the increasing soil degradation of South-eastern Nigeria – with particular reference to the rice growing soils of the region, selected rice producing soils of Abia State were characterized with a view towards acquiring a holistic understanding of the soils and their fertility status. Random soil survey technique was used in field sampling. Four profile pits were dug in two different towns i...

The Growth and Yield Performance of Groundnut (arachis Hypogea )cultivated Under Various Fertilizer Inputs on an Alfisols in the Southern Guinea Savanna Zone of Nigeria

Uzoma, A.O.*, Jemiyo C.A, Bala A., Adeboye M.K.A, A.O Osunde

The response of groundnut variety SAMNUT22 to various fertilizer inputs was examined on a field experiment at the Teaching and Research Farm of the Federal University of Technology, Minna during the 2010 cropping season. A total land area of 0.06 ha was cleared, harrowed, ploughed and ridged. Thirty plots of size 4 x 3.5m were marked out at plot spacing of 1m and replicate spacing of 2m. Soil samp...

Characterization and Fertility Status of Wetland Soils in Abia State Agro-Ecological Zone of Southeastern Nigeria.

AHUKAEMERE C.M.*, ESHETT E.T, AHIWE C.

The realization of the potentials of paddy soils necessitates taking the inventory of their micronutrients status. The available micronutrients status of soils of two varying paddy lands (upland and lowland) were studied. A random soil survey technique was used in field sampling. Four representative soil profiles, two in each paddy soil type were dug. Soil samples were collected from the profiles ...

Combined Application of Ureaand Sawdust Ash in Okra Production Effects on Yield and Nutrients Availability

Okusami, Temitope A.*

Trials were conducted at Emmanuel Alayande College of Education Teaching and Research Farm Lanlate, southwest Nigeria in 2012 and 2013 to investigate the effects of combined applications of sawdust ash (SDA)and urea (U) as fertilizer in okra production. There were five treatments and control, replicated three times in randomised complete block design. Treatments were a control, urea at 240 kg/ ha,...

Contaminant Limit (c/p Index) of Heavy Metals in Spent Oil Contaminated Soil Bioremediated with Legume Plants and Organic Nutrient

Udom B. E.*, Ano, A. O., Chukwu L. I.

Three legume plants (Gliricidia sepium, Leucaena luecocephala and Calapogonium caerulean) alone or in combination with 0.5% (w/w) poultry manure were tested for their ability to reduce the heavy metals and toxicity criteria of a sandy soil contaminated with 5% (w/w), (equivalent of 50,000 mg/kg) spent lubricating oil, each for two years. The oil and poultry manure led to buildup of Ni, Pb, Zn and ...

An Assessment of Land Use/cover Using Conventional and Satellite Data in Tomas Irrigtion Scheme, Kano, North - Western Nigeria.

Sulaiman Yau Lawan*, B. A. Raji, MALGWI W.B., Uyovbisere E, Manasseh E.A.

Soil is a life supporting system upon which human beings have been dependent from the dawn of civilization. Hence comprehensive information on soil resources, its potentials, limitations and capabilities are required for a variety of purpose, which includes sustainable agriculture, reclamation of degraded lands among others. Data from SPOT 5 (2005), a satellite image and ERDAS, a geographic Inform...

MORPHOMETRIC CHARACTERIZATION AND AGRICULTURAL IMPLICATIONS OF GULLY EROSION IN GASHALA AREA, HONG LGA, ADAMAWA STATE, NIGERIA.

JOHN WAMARHYEL GUNDIRI*, Waizah, Y., Ibrahim Adamu, Joshua Bitrus Ndirmbula

An impact assessment of gully erosion hazards on food security was carried out in ten (10) locations of arable lands in the Gashala environs in the year 2023. The study comprised measurements of the physical characteristics, which include texture, bulk density, porosity, length, depth and the width of each gully site. The gully volumes were also measured and classified according to Shahrivar and C...

Potassium Distribution in the Sand, Silt and Clay Fraction of Soils Developed Over Talc in Odo-Ogbe, Kogi State, Nigeria

AJIBOYE G. A.*, Ogunwale J. A., Aduloju M. O.

Potassium (K) status of soils formed over talc at in a Southern Guinea Savanna Zone of Nigeria was assessed by the exchangeable, acid extractable, residual K and total K values in the sand, silt and clay fractions of the soils. Soil samples collected from genetic horizons of profile pits dug in five mapping units were fractioned into the three particle sizes of sand, silt and clay and exchangeable...
