Effect of Flood and Drip Irrigation Systems on Growth and Productivity of Picual and Arbequina Olive Cvs. Grown in New Reclaimed Lands

Type: article
Abstract: Water use (WU), water use efficiency (WUE), growth,productivity of Picual and Arbequina olive cultivars were studiedunder two irrigation systems (flood and drip) during 2007and2008 seasons.Results showed that, seasonal water use of olive trees grownunder flood and drip irrigation was 704.04 and 446.95mm/feddan/year, respectively (average of the two seasons). Olivetrees subjected to drip irrigation produced the highest yield/tree16.6 Kg (average of the two seasons). Yield decreased by about23.67% when trees were exposed to flood irrigation system. Yieldefficiency and water use efficiency of olive tress had the sametrend. The maximum values, in this respect, were obtained by olivetrees grown under drip irrigation followed in a descending order byflood irrigation, respectively.On the contrary, olive trees grown under flood irrigationsystem gave higher values of vegetative growth parameters andpercent of fruit dry weight. However, it gave less fruit yield as wellas percent of oil in flesh dry weight. Olive trees grown under drip < br />irrigation system gave the highest value of oil% per flesh dryweight (43.99% average of the two seasons). Meanwhile, thispercent decreased by about 8.54% when trees were irrigated byflood irrigation.Moreover, from the obtained data, it is clear that Picual cv. hadthat bigger tree canopy, fruit yield, fruit weight, fruit dry matterand fruit oil content more than Arbequina cv.Consequently, it could be recommended cultivate trees ofPicual cv. in the new reclaimed land as it was more suitable thanArbequina cv.
