Abstract
This work was carried out to study the effect of using laser land leveling and interaopping systems on the yield and total net return in soybean - maize association. Two field experiments were conducted at Sills Agriculture Farm Research Station. Beni-Suit Governorate during 2001 and 2002 seasons. The intercrop combinations Included maize variety (Threewaycross 310) and soybean variety (Clark) grown in clayey soil. The results are summarized as follow: 1- WUE values wore 0.94. 0.87 and 0.73 kg/m3 for 0.03% slope. zero level and traditional leveling, respectively for maize yields. They were 1.52, 1.28 and 1.14 kg /m3 for the same plots respectively for soybean yield. The yield of maize increased by15.4% and 9 %. and the yield of soybean increased by22.60% and 7.66% in zero level plot and 0.03% slope plot respectively compared with traditional leveling. 2- WUE values were 0.77, 0.74 and 0.72kg / m3 for the maize, maize: soybean ratios (2:2) and (2:4) treatments respectively. The Increase in the yield of solid maize treatment was found to be 22.8 and 62.4% over (2:2) and (2:4) treatments respectively.-WUE values were 1.17, 0.89 and 0.60 kg/m3 for the solid soybean.(2:4)and (2:2) treatments, respectively. (2:4) System recorded a yield reduction of only IS % compared with solid soybean yield, while the reduction in (2:2) augmented to as much as 38.60 %. 3-The values of WUE for solid maize wore 0.96. 0.91 and 0.79 kg/m3 for 0.03% slope, zero level and traditional leveling, respectively. The values of (2:2) were 0.82, 0.79 and 0.71 kg/m3, while the values 01 (2:4) were 0.81, 0.78 and 0.70 kg/m3. of the some plots respectively. The values of WUE for soiled soybean were 1.48, 1.00 and 0.81 kg/m3 for 0.03% slope. zero level and traditional leveling, respectively. The valuta of (2:4) were 1.06. 0.88 and 0.66 kg/m3, while the valueS of (2:2) were 0.85, 0.81 and 0.53 kg/m3 at the same plots respectively. 4-The increase in yield of soybean grown in pure stand over those grown in the ratio 01(2:4) in 0.09% slope plot was 38.77%, while the Increase in yield of soybean crop In 0.03% slope plot and grown in (2:4) pattern over that grown in (2:4) pattern in traditional leveling was 35.93% .
