Abstract
SummaryThe effects of four (25,50,75 and 100%) levels of evaporation replenishment under drip irrigation (1 emitter per plant and 1 emitter per 2 plants) and furrow irrigation (2.5 and 5.0 cm depth) were investigated during 1984 and 1985. Increase in evaporation replenishment increased the relative water content, osmotic potential and yield, and decreased water-use efficiency (WUE) and canopy temperature. Drip irrigation with one emitter per 2 plants recorded higher relative water content, osmotic potential, yield and WUE as compared with furrow irrigation to 2.5 and 5.0 cm depths. The differences in the above measurements between the two drip or furrow irrigation treatments were not significant. The interaction effects indicated that replenishment of 25% evaporation losses under drip and 50 to 75% evaporation losses under furrow irrigation were optimum for realizing higher yields of watermelon.
