STUDY ON DEVELOPING OF IRRIGATION METHOD IN DELTA REGION

Abstract

The present work was carried out at El-Karada station, Kafr El-Sheikh .. Governorate during Summer season of 2003. Table 3-1 indicates the mechanical

analysis of the soil and the soil texture which was clayey,

The experimental treatments were arranged in split-split plot design with three replicates as shown in Fig. 3.1. The main plot was assigned as two irrigation methods (irrigation through earth canal and irrigation through lining canal ). the sub plot treatments were the furrow length 13, 27 and 40 m respectively.The sub-sub plot treatments were three different values of irrigation water discharge(l.S a!ld 2 m3/min). The parameters for different treatments were calculated as follows :­

!-Amount of applied water to each treatment

2-Root volume.

3-Leaf area index.

4-Corn yield.

5- Water use efficiency

6-Conveyance effieciency

•According to the obtained results, it may be concluded that;

1-Applied irrigation water,

a-The lining canal irrigation method saved water about 19% compared with unlining carmal. b-Increasing furrow' length tended to increase the amount of water for unlining

canal and lining canal irrigation method,
