THE EFFECT OF ORGANIC MATTER ON RUNOFF, SOIL LOSS AND CROP YIELD AT ANJENI, ETHIOPIA
Specifically, the study attempted to estimate the extent of the various components of price. The study was conducted in North-eastern Nigeria. Purposive sampling technique was used to select two states, of Adamawa and Taraba, from the six states that made up the North-east geopolitical zone. Only secondary data were used in the study. Secondary data on monthly bases for the prices of 100kg of three cereal grains, maize, rice and sorghum in both rural and urban markets in the study area were obtained from Adamawa and Taraba States Agricultural Development Programme offices for a period of 10 years (2001-2010). Data were analyzed using price decomposition technique. The results revealed that, the trend component showed an upward movement for all the three commodities. The seasonal variation had indexes ranged from 198.15 to 52.61, 142.83 to 61.88, and 141.44 to 66.25 for maize, rice and sorghum, respectively. The random and cyclical variations had negligible and insignificant indexes with the former having 0.01 all through and the later ranging from 0.93 to 1.26. This study would add to the volume of literatures on price analysis and also be an invaluable source of information to all stakeholders in the field of agricultural marketing and price.
