abstract unbalance using of chemical fertilizers cause decline the soil quality and fertility, environmental pollution and specially soil and water resources pollution. the use of animal manure is a replacement to chemical fertilizers. therefore, recognizing of demographic, technical-extensional and agronomic affect on farmer's decision making process to use of animal manure will have important...

Despite the fact that erosion undermines productivity in the Ethiopian highlands, adoption of fertility enhancing techniques remained very minimal. The objectives of this study is to examine factors affecting adoption of fertilize and manure use and their interrelationships using plot and household level data collected from 211 farm households. A two-stage probit model results revealed a negati...

Effects of NPK 15:15:15 compound fertilizer and planting season on flowering and sex expression of pumpkin were analyzed at the Teaching and Research Farm, Obafemi Awolowo University, Ile-Ife, Nigeria in year 2010. Results deciphered that day to 50% flowering, number of male and female flowers responded to season than fertilizer rates. Late season planting reached 50% flowering 5 days earlier t...
