Soil Organic Matter and Its Active Pools as Affected by Legume/cereal Cropping Systems Under Some Agronomic Practices in the Derived Savannah Zone of Nigeria

Uzoh I .N*, Ezepue, G.U.C

Introduction of grain legumes facilitates farmers’ acceptance in adopting legume cropping system. This study evaluated effect of four cropping systems on soil organic carbon (SOC), total vesicular arbuscular mycorrhiza (VAM) spore count, soil microbial biomass carbon (SMBC), soil microbial biomass nitrogen (SMBN) and soil microbial biomass phosphorus (SMBP) within two locations (Nsukka and Moniya)...

Testing the Goodness of Fit of Infiltration Models for Soils Formed on Coastal Plain Sands in Akwa Ibom State, Southeastern Nigeria

Ogban P. I.*, Jude Obi, Anwanane, N. B., Edet, R. U., Okon, N. E.

Infiltration of water into the soil is an important physical process affecting the fate of water under field conditions, especially, the amount of subsurface recharge and surface runoff and hence, the hazard of soil erosion. The study was conducted to investigate the capability of six infiltration models, namely, Kostiakov, modified Kostiakov (A) and (B), Philip, modified Philip (A) and (B) to des...

Soil Fertility Management among Cucumber (Cucumis Sativus L.) Farmers in Ibadan, South-West Nigeria

Utibeabasi Brownson*, OLOGUNDUDU, O. M., OMONIYI J, AdeOluwa O. O

Poor soil fertility reduces the yield, market value, and sustainable production of cucumber. This study examined soil fertility practices among cucumber farmers in Ibadan. A purposive sampling method was used to select 10% of cucumber farmers from six blocks, namely Akinyele, Lagelu, Egbeda, OnaAra, Oluyole, and Iddo in Ibadan-Ibarapa agricultural zone, Oyo State. A structured questionnaire was ...

Soil Solarization and Amendment Using Clove (syzygium Aromaticum )in Control of Fusarium Oxysporum F. Sp. Lycopersici

Adekunle A. T.*, Odeh S.

Soil treatment using solarization and amendment with ground clove (Syzygium aromaticaum) was carried out in a screen house experiment to control Fusarium oxysporum f. sp. Lycopersici. The study evaluated two thickness of clear polyethene plastic, two concentrations of ground clove as well as a combination of the treatments. Colony counts for F. oxysporum were carried out for samples from all treat...

Classification and Suitability Evaluation of the Soils of a Toposequence at Odeda, Ogun State for the Production of Rice (oryza Sativa)

AJIBOYE G. A.*, Alabi K. O., Aiboni V. U.,, Okeleye K. A, ADESODUN Johnson Kayode

A detailed survey of the soils of a toposequence at Odeda, Ogun State was conducted to characterize, classify and assess the suitability of the soils for sustainable production of rice. The rigid grid method of survey was adopted for soil mapping while the linear parametric and square root models were used for assessing the suitability of the land for rice production. The result of the study showe...

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

Fasina A.S.*, 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, Osunde A.O.

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 ...
