Effects of Plant Mulch and Vine Care on the Growth and Yield of Cucumber (cucumis Sativus L.)

Abidemi, A. A*, Ewulo, B. S, Aiyelari, O. P., Jiandong H.

Field experiments were conducted during the 2015 cropping seasons on a farmer’s farm, Abeokuta, Ogun State, Nigeria to study the effects of plant mulch and vine care on soil properties, leaf nutrient content, growth, and yield cucumber (Cucumis sativus L.). Plant mulch was applied as zero mulch (0 t ha-1 ), Tithonia diversifolia (10 t ha-1 ), Chromolaena odorata (10 t ha-1 ) and vine care as no st...

Land Suitability Evaluation of the Wetland Soils of Obukiyo, Oju Lga of Benue State, Nigeria for Rice (oryza Sativa) Production

Ogbu O. J,*, Idoga S., Abagyeh S. O. I, Usman, J.

The inland wetland soils of Obukiyo, Oju Local Government Area of Benue State, Nigeria were evaluated for the production of rice. The physical, chemical and morphological features of the soils were matched with the requirements of the crop (rice), and the overall suitability rating of the soils was obtained using limitation method. Unit 1 soils were rated as marginally suitable (S3) for rice produ...

Effect of Biochar on Available Phosphorus Status in Alfisols Derived from Charnockite in Ekiti State, Nigeria

Ilori, A. O. A.,*, Shittu, O. S.,, Ayodele, O. J., Awe, G.O., Oso, A. O.

Biochar, a carbon-rich product of pyrolyzed biomass, has been used as an amend- ment to improve the properties of marginal highly-weathered soils in the tropics characterized by widespread phosphorus (P) deficiency. Alfisols derived from charnockite in Ekiti State are typically deficient in available phosphorus. Two alfisols from Ire-Ekiti and Ijan-Ekiti were amended with 0 (P-only), 5, 10 and 20%...

Determination of Some Soil Physico - Chemical Properties of an Ultisol as Influenced by Npk Fertilizer and Cropping Ratios of Maize (zea Mays L. ) – Egusi Melon (citrullus Colocynthis Hook L.) in Rainforest Area of Nigeria

Ehigiator J.O.*, Okunima D.E., G.O. Iremiren, I. W. Oghiren

Field experiments were conducted (2009, 2010, 2011) at the Teaching and Research Farmland of the University of Benin to determine the effectof seven ratios (1:0, 0:1, 1:1, 2:1, 3:1, 1:2 and 1:3) of maize-egusi melon intercrop under four (0, 200, 400, 600 kg/ha) and six (0, 200, 400, 800, 1000 kg/ ha) levels of NPK fertilizers on some soil properties of an utilsol in Benin City, Nigeria. The result...

Yield Decline of Major Crops Induced by Erosion on the Ultisols of Owerri, Southeastern Nigeria: Maize Response to Natural Erosion

Nnenna Nnannaya Oti*

Few studies have been made to quantify the yield decline trends of major stable crops induced by erosion (natural and artificial) on the ultisols of Southeastern Nigeria, it is known that erosion’s impact on soil productivity is crop, environment and soil specific. This paper reports an aspect of a larger body of research work conducted between 1996 and 2002 to document erosion – in- duced product...

Assessment of the Responsiveness of Soybean Varieties to Bradyrhizobium Japonicum Inoculation in Ogbomoso, Southwest Nigeria

Olaboopo, M. T., Kolawole, G. O.*

Soybean varieties may respond differently to rhizobium inoculation, for im- proved yield and nitrogen fixation. Therefore, responses of ten soybean varieties to rhizobium were evaluated in 2018 at the Ladoke Akintola University of Tech- nology, Ogbomoso, Nigeria, to determine if rhizobium will improve the perfor- mance of the varieties. The soybean varieties (main plot) and rhizobium (+ or -, subp...

Influence of Oil Palm Cultivation on Topsoil Properties in Nigerian Institute for Oil Palm Research, Akwa Ibom State

Chukwu E. D*, B. T. Udoh, Afangide, A. I, Osisi A. F

The thin layer of soil covering the surface of the earth represents the difference between survival and extinction for most land-based life. Four oil palm blocks of varying ages: 57 years (B-57), 39 years (B-39), 17 years (B-17), and no oil palm block (B-0), which served as the control, were identified and used for the study. The result showed that in B-0, B-17, B-39 and B-57, 7 (22.58%), 10 (32.2...

Comparing the Effect of Biological Amendments and Chemical Fertilizer on Bacterial and Fungal Population

Edosa, Ifeyinwa Valerie1*, Aleladia B. O, Osarhiemen, V. O.

Amelioration of degraded soils has triggered interest regarding alternatives to supply nutrient and improve microbial diversity through the integrated use of organic manure and biofertilizers. In this light, a screenhouse experiment set in a completely randomized design (CRD) with seven (7) treatments, Bacillus thurin- giensis (5 ml), digestate (22.4 t ha-1), 50% of digestate + NPK 15:15:15 (11.2 ...

Performance of Horton Infiltration Model in Predicting the Infiltration Capacity of Some Soils of the Sudan Savanna of Nigeria

Girei, A. H.*, Nabayi, A.,, Aliyu, J.,, Garba, J,, Hashim, S.A.,, Alasinrin, S.Y., Abdullahi, M Y

Infiltration study is very crucial in modelling water requirement of crops during their growth season. Infiltration rate measurements were carried out on dryland areas of Sokoto, Sudan savanna ecological zone of Nigeria, using the double ring infiltrometer. Disturbed and undisturbed soil samples were used to determine some physical characteristics (Texture, Saturated hydraulic Conductivity, partic...
