Lowland Rice Yield Responses to Variation in Water Management in a Sudan Savannah Soil of Nigeria

Abubakar Halilu Girei^*, Nabayi, A.,, Amapu I. Y, Mudiare, O. J, Abdulkadir, A .

This study investigates the applicability of reduced water management (alternate wetting and drying AWD) practice alongside continuous flooding (CF) which is the traditional water management practice of lowland rice production in Sudan savanna ecological zone of Nigeria. Rice growth component variables from each of the management practice were compared to identify the best in terms of re- duced nu...

Restorative Effects of Amendments on Artificially Degraded Soils in the Southern Guinea Savanna of Nigeria

Adaikwu A.O^*, F. K. Salako, Busari M. A., Jamiu Oladipupo Azeez

An evaluation of the productivity of degraded alfisols at Makurdi and Otobi, Nigeria, using artificial desurfacing techniques (ADT) was carried out in 2012 and 2013 cropping seasons. The study was a split-split plot experiment arranged in a Randomized Complete Block Design with three replications. The soil was desurfaced at 0 – 5, 0 – 10, 0 – 15, 0 – 20 cm and the undesurfaced soil, 0 cm (control)...

Effects of Liming on Some Properties of South Eastern Soils of Nigeria

Salimon Bello^*, Udofia A. E.

Liming with agricultural lime was carried out at some locations in the old South-eastern part of Nigeria. One hectare each was acquired at Akpabuyo (Cross River State), Calabar (Cross River State), Amakama (Abia State) and Igbariam (Anambra State) in August 2008. The plots were cleared, treated with 1.6 tons of agricultural lime and properly mixed by ploughing and harrowing up to 20 cm depth. The ...

Suitability Assessment of Soils Supporting Oil Palm Plantations in the Coastal Plains Sand, Imo State, Nigeria

Ukaegbu E.P.^*, Osuaku, S.K., Okolo, C.C.

Due to the declining yield of Oil palm, soils of the coastal plains sand of Imo State supporting oil palms were evaluated. A bulked sample was taken from each of the ten sites studied, at 0 – 20cm and 20 – 40cm depths and analysed in the Laboratory. Soils textures were dominated by sandy loam at the surface, but sandy clay loam at the subsurface. Ranges of values of parameters at the topsoil were:...
