| Abstract | ||
| Two field experiments were conducted at Nubaria Agric. Res. Station during 2000 and 2001 seasons. The objectives of this investigate was aimed to study the effect of tillage systems (conventional tillage and no-tillage) and four intercropping patterns: 1) Pure stand of soybean was sown in hills 10 cm on each side of ridge (120 cm) with two plantslhill. Pure stand of sunflower and maize were sown in hills 30 cm on each side of the ridge with one plant/hill. 2) Soybean seeds were sown on one side of the ridge and sunflower was sown on the other side of the ridge and maize was sown on the middle .3) Soybean was sown on the middle of the ridge among maize and sunflower plants, and 4). Soybean was sown on one side of the ridge, and maize was sown on the other side of the ridge and sunflower was sown in the middle on the ridge. A split plot design with four replicates was used. Results showed that tillage systems and intercropping treatments significantly affected plant height, number of pods/plant, number of seeds/plant, seed yield/plant, seed yield/feddan and oil seed percentage. The highest seed yield/feddan was obtained from tillage conservation in the two seasons compared to no-tillage. Also, pure stand gave higher seed yield of soybean than that of intercropping treatments. The results indicated thatthe interaction between tillage systems and intercropping treatments interaction had a significant effect on plant height, number of pods/plant, number of seeds/plant and seed yield/feddan. The highest seed yield/feddan was obtained by tillage system and soybean which sown on one side of the ridge. The results indicated that tillage system, intercropping treatments and interactions between tillage system and intercropping patterns had a significant effect on grain yield of maize and sunflower seed yields/ feddan. Pure stand of maize and sunflower gave higher maize grain yield and sunflower seed yield/fed than that of intercropping patterns. It can be concluded that sown soybean on one side of the ridge 120cm apart and 10 cm between hills with tillage conservation could be recommended for raising soybean productivity under the conditions of Nubaria area. | ||
