Rainfall is undoubtedly a determining agro-meteorological factor in the cultivation and production of cocoa. This work has revealed that rainfall has a constraining ability on cocoa yield in the core cocoa production areas of Ondo state, Nigeria. It was also established that cocoa production is in its best in areas like: Idanre, Ondo, Akure, Ile-Oluji, Owo e.t.c, which have yields above 1000MT per annum and rainfall lesser than 51.30mm. Cocoa yield was also shown to be the inverse of annual rainfall level. This was evident as cocoa yield increased in the early and latter months of the year when the rains are yet to fully come, and suffered in the mid year at the heart of raining season. A model of rainfall as it affected cocoa yields was achieved in this work.

The nature of urban road transportation problems in Nigeria as at today can best be appreciated by looking at the trend of its development since Nigeria came into existence. Thus, this paper, attempt a cursory review of urban road transportation system in Nigeria from 1960 to 2006 (a period of 46 years). The paper adopts exploratory method of research to examine and discuss relevant issues of interest in the history of Nigeria road transport system in six sections. It was discovered that urban road transport system in Nigeria is inefficient and grossly inadequate even after 46 years of becoming independent from Colonial Rule. The paper suggested the construction of more motor-able roads within cities in order to increase the network; encourage increased public and private participation in the provision of transport services within cities and inter-cities transport system. The adoption of motorcycle as public mode of transportation in cities should be institutionalized since the users are constrained to use this means of transportation in the absence of alternative. However, policies guiding the regulations and use of this mode should be formulated and monitored so that its use would not impact negatively on the commuters' mobility rights and lives. Similarly, government should provide enabling environment that would guaranty efficient and adequate movement of vehicles in cities.
