	<span style=\"font-size:10pt;\"><span style=\"font-size:12px;\">Field experiment was
conducted for one growing season (2012) in clay loam soil at the Experimental
Farm of Faculty of Agriculture, Southern Illinois University at Carbondale
(SIUC), USA on soybean crop to study the effect of: 1) the closed drip irrigation
system: closed circuits with one and two a manifolds for lateral lines (CM1DIS;
CM2DIS) and traditional drip irrigation system (TDIS) as a control; and 2) lateral
lines length (LLL): LLL1, LLL2 and LLL3 (40, 60,80 m) on soybean growth, yield, oil, protein content
and water use efficiency. Plants were drip irrigated every 4 days. N, K</span><sub><span style=\"font-size:12px;\">2</span></sub><span style=\"font-size:12px;\">O

the treatment used could be ranked in the following ascending orders: TDIS &lt;
CM1DIS &lt; CM2DIS and LLL3 &lt; LLL2 &lt; LLL1; 2) Differences in the means of
