2.4 Mareko fana water requirement estimation and transplanting
INFILTRATION
Reference evapotranspiration was estimated by the Penman-Monteith method by using cropwat 8.0. The input dates were location (70 36’ 00’’N latitude and 380 24’ 55’’E longitudes and altitude of 1600 m), climatic data (sunshine, wind speed, relative humidity, temperature and rainfall), crop type and soil data (OMC, infiltration rate, field capacity, permanent wilting point and total available water). During calibrating the software four days of irrigation intervals and with 90% efficiency.Where ETThe ETO was estimated from daily climate data collected from Alage Meteorological Station and computed using CROPWAT 8.0 for windows model and Kc for pepper was taken as 0.6 at initial stage, 0.6 to 1.05 at development stage, 1.05 at mid-season and 0.9 at late season [Then crop water requirement can be computed by empirical methodologies primarily based on meteorological data in view of difficulties associated with direct measurement [Where, Kc = Crop factor, ETUniform, healthy, and vigorous seedlings (standard seedlings) having a height of 20–25 cm [Irrigation water required to meet evapo-transpiration need of crop during its full growth.Where; NIR net irrigation depth in mm, ETc the crop water requirement in mm and Pe the effective rainfall in mm.By taking the average application efficiency (90%) for drip irrigation from 85–95% range [
