Abstract

A field trial was carried out at Sakha Agricultural Research Station, Kafr El-Sheikh Governorate during the two successive winter seasons 2010/2011 and 2011/2012. The aim of the work was to assess the effect of irrigation lengths on barseem yield and its water parameters. Five irrigation lengths were examined; 100% of strip length (S.L) as control (Trt. A), 95 %(Trt. B), 90%  S.L(Trt. C), 85% S.L(Trt. D) and 80% S.L (Trt. E). Average of seasonal water applied were, in adescending order as follow: A(2615.0) > B (2507.7) > C(2409.0) > D(2330.5) > E(2215.1) m3 fed-1. Mean values of water saving in the two growing seasons comparing with the control 107.4, 206.0, 284.5 and 400.0 m3 fed-1 or 4.1, 7.9, 10.9, and 15.3% for the cut off treatments B,C,D and E respectively. The highest average of yield per unit of applied water (W Ut E) and consumed water (W U E) averaging 16.58 and 24.80 kg m-3 for each, respectively were obtained under 90% S.L (Trt C).
