Efficacy of Quasi Agro Binding Fibre on the Hybrid Composite Used in Advance Application

The choice for natural fibre obtained from agricultural products is on the rise due to its solution to eco-friendly, environmental and improved mechanical properties concerns. Its abundant availability, low cost, emission reduction and adaptability to base material for composite make it a prime material for selection. This review explores diverse perspectives to the future trend of agro fibre in terms of the thermo-mechanical properties as it applies to advanced application in building structures. It is important to investigate the ecofriendliness of the products of composites from fibres in agricultural wastes so as to achieve a green and sustainable environment. This will come to fore by the combined efforts of both researchers and feedback from building stakeholders

Estimation of rainfall indices for the determination of length of growing season and timing of arable crop cultivation in Ogun State

The study assessed the rainfall distribution pattern over the last 25 years (1989-2004) to determine the length of growing season and timing of arable crop cultivation in Ogun State. Secondary rainfall data was obtained from the four meteorological stations in the State and subjected to arithmetic calculations for estimation of raindays, drydays and rainfall variability in the study areas. The results show that the month of March marks the onset of rainy season in the State while October marks its cessation. Out of the growing period of 208 days, 88 days were observed as having sufficient rainfall (0.25mm and above) per day. Based on Seasonality Index (S.I) of 0.32 and monthly and annual coefficient of variability of less than 50 percent and 20 percent, respectively, estimated for the study area, it was ascertained that the raindays were well spread out through the months of the rainy season. Observed high frequencies of 2 and 4 dryday spells suggest that rainfall will take place mostly after 2 or 4 successive days of no rain. In the light of this, it was concluded that rainfall situation in Ogun State will favourably support arable crop cultivation and as such land preparation should be completed by mid-April and followed by seed sowing between then and early May.
