ABSRACT - [ Total Page(s): 1 ]Agriculture in Nigeria is mainly dependent on rainfall which is variable in nature. Therefore, the need to have a full knowledge of its pattern and trend is pertinent in order to achieve food sufficiency. This study examined the effect of precipitation effectiveness indices: Onset date, cessation date, length of rainy season and occurrence of pentad dry spells (5, 10 and ≤15) days on the yield of millet, sorghum, rice and maize in Sokoto State, between 1993 and 2008. Walter‟s 1967 method was used to derive the selected precipitation effectiveness indices while dry spell parameters,

CHAPTER ONE - [ Total Page(s): 1 ]CHAPTER ONEINTRODUCTION1.1BACKGROUND TO THE STUDYThe limit to the productive capacity of land resources are set by climate, as climatic variability constitutes a major constraint to agricultural production especially in developing countries. However, adequate knowledge of climatic parameters minimizes climatic constraint to food production (Farajzedah et.al., 2012).The world population is projected to continue increasing well into the present century. The primary question is whether and how global food production may be increased to provide for the population expansion. It will ... Continue Reading
