Table 7-2 Descriptive Statistics

In addition to crop genetic diversity, explanatory variables include conventional inputs (land, labor, animal, urea), environmental and soil conditions (erosion and water logging, slope, fertility, and altitude), and managerial variables (years of experience, number of barley plots). Land, labor, and animals are the most important conventional inputs. The average input of labor is 70 person days and of animals 40 oxen days. Regarding the environmental and soil conditions of farms in the sample, on average 5% of operated plots are affected by severe erosion and water logging and 7% are located on steep slopes. The most important problem is low soil productivity: 37% of plots are infertile. An average of over nine years was spent cropping (maximum of 14 years and a minimum of one) about three plots per household. As of 1998 only 15% of household heads had formal schooling (only 6% had over two years), and 7% participated in literacy programs (Pender and Gebremedhin 2004).
