Abstract :

A field experiment was executed during 2012/2013 and 2013/2014 seasons at Sids Agric. Res. Station, to evaluate irrigation scheduling according to three coefficients of daily pan evaporation, i.e. 1.25 (I1), 1.00 (I2) and 0.75 (I3) on yield, quality and some water relations of two Egyptian clover cultivars Gemmeiza 1 (V1) and Giza 6 (V2). A strip-plot design was used in this study. The results indicated that: The irrigation at 1.25 pan evaporation coefficient (PEC) produced highest values of number of applied irrigations, seasonal consumptive use, water use efficiency on fresh weight basis, plant height, number of leaves/stem, leaves/stem ratio, fresh and dry yields and crude protein and fiber yields. Whereas, the highest values of water use efficiency on dry weight basis recorded under irrigation at 0.75 PEC. The Giza 6 cultivar excreted the highest values of seasonal consumptive use, water use efficiency on fresh and dry weight basis, plant height, number of leaves/stem, leaves/stem ratio, fresh and dry yields as well as crude protein and fiber yields. Key Words: Irrigation scheduling, Egyptian clover cultivars and Water use efficiency
