Simulating Effects of Drainage Design Parameters on Optimum Crop Yield Using Drainmod

ABSTRACT Agricultural water management systems aims to provide crop water requirements to sustain optimum yield.

SIMULATING THE SENSITIVITY OF MAIZE CROP PROPAGATION TO SEASONAL WEATHER CHANGE

ABSTRACT The paper simulates the sensitivity of maize crop yield response to temperature increase with appropriate irrigation scheduling that may obviate the negative impact of temperature increase on crop yield.

PRODUCTION AND TESTING OF WOOD PLASTIC COMPOSITES BOARDS FROM MIXED PARTICLES OF GMELINA ARBOREA AND KHAYA IVORENSIS

ABSTRACT A lot of wood waste is generated from wood species in the Nigerian wood mills which are hazardous to the mills, mill workers and the wood.

ON THE ADEQUACY OF EVAPOTRANSPIRATION ESTIMATE USING PRIESTLY-TAILORED APPROACH

ABSTRACT The measurement of potential evapotranspiration ET using priestly-taylor formula in humid region was carried out at Shasha along Ojoo-Moniya road, Akinyele Local Government Area, Oyo State.

Modelling Interconnectedness of Subsurface flow processes from a simple conceptual infiltration model

ABSTRACT The study determined subsurface flow processes of 92.3ha catchment area in order to examine functional relationship among the surface and subsurface flow variables from the water balance components data.

SIMULATING THE IMPACT OF CLIMATE CHANGE ON YIELD REDUCTION OF VEGETABLE CROP PROPAGATION

ABSTRACT Effects of climate change on the yield reduction and prediction of vegetable crop was carried out using CROPWAT 8 with irrigation scheduling condition; critical depletion at a water application depth of 2mm, definite interval of 3days at a depth of 2mm and no irrigation.

Pretreatment effects on hydration behaviour of cement bonded boards made from Eremospatha macrocarpa and laccosperma secondiflorum canes

ABSTRACT The effects of pre treatments on the setting time, maximum hydration and time ratio of two rattan species particles mixed with portland cement were investigated.

COMPATIBILITY OF CALAMUS DEERRATUS AND LACOSPERMA SECUNDIFLORUM RATTAN PARTICLES WITH ORDINARY PORTLAND CEMENT

ABSTRACT An investigation was conducted to determine the optimum water to cement ratio for a locally manufactured Portland cement for use in wood composites.

Best Distribution and plotting positions of daily maximum flood estimation at Ona River in Ogun-Oshun River Basin, Nigeria

ABSTRACT This paper discusses how normal, lognormal, and log pearson type 3 distributions were investigated as distributions for modelling at site annual maximum flood flows using the Hazen, Weibull, and California plotting positions at Ogun-Oshun river basin in Nigeria.

Analysis of Climatic Factors for Selection of Greenhouse Glazing Materials in Ilorin Nigeria

ABSTRACT The effect of climate change in recent times has necessitated the need for a controlled environment for the cultivation of many crops which where hitherto cultivated under natural tropical conditions.

DEVELOPMENT OF MILLING ANCILLARY COMPATIBLE WITH TWO STROKE POWER SAW ENGINE FOR SHORT LOG CONVERSION

ABSTRACT Chainsaw milling is an inevitable means of preventing quantum wastage of valuable and scarce wood resource in un accesible locations.

Recycling of Bamboo (Bambusa vulgaris Schrad) Recovered from Scaffold into Material for Furniture Production

Abstract Interest is growing daily on the utilization of bamboo as a reliable supplement to wood in furniture production to mitigate the scarcity of wood raw material supply. This study explored the viability of recycling bamboo recovered from scaffold into intermediate raw material for indoor furniture production. Strips were processed from the recovered Bambusa vulgaris Schrad and were subjected to conventional treatment methods with some modification to simplify the treatment. The durabil...

ASSESSMENT OF THE NOISE LEVEL GENERATED DURING PLOUGHING AND HARROWING OPERATIONS IN IBADAN NIGERIA

ABSTRACT  In an attempt to meet the food demand by the ever increasing human population, the use of machines in the performance of agricultural operations is increasingly being emphasized. Two of the most common operations for which machines are used on the farm are ploughing and harrowing. Tractor operators who perform these functions are known to spend long period of time working with the machines and various implements which generate substantial noise. Exposure to excessive noise could be...

Effects of Selected Pre-treatment Methods on the Hydration Behaviour of Rattan-Cement Mixtures

Abstract The influence of calcium chloride (CaCl2 ), magnesium chloride (MgCl2), hot-and cold-water pre-treatments, and prolonged storage on the hydration behaviour of particles extracted from Calamus deerratus and Laccosperma secundiflorum rattan canes mixed with cement was investigated. While the untreated rattans inhibited cement setting, pre-treatments generally improved compatibility. The addition of chemical additives and aqueous pre-treatments enhanced the compatibility of the rattan-...

The Status of Greenhouses Utilization in Oyo State, Nigeria

ABSTRACT The toll of climate change on the Nigerian agricultural system in recent times has resulted in the decline of agricultural production constituting a threat to food security. There is therefore an urgent need for strategies to reverse the situation and greenhouse farming is contemplated as a possible option. Towards the successful adoption of this strategy, a survey was conducted using Oyo State as a case study to establish the present status of the use of greenhouses in the region. A...
