| Abstract | ||
| Two field experiments were carried out in Gemmeiza Research Station during the two summer successive seasons 2013 and 2014 to investigate the effect of three soil tillage depths i.e. 15, 20 and 25 cm and three intercropping patterns i.e. P1-100% maize (single cross 128) + 50% soybean (variety Giza 111) in ridges (0.70 m in width) P2- 100% maize + 50 % soybean in beds (1.40 m in width) and soybean was intercropped with maize at the two rows on bed back, whereas maize was planted at both sides of the bed and P3- Pure stands of maize and soybean were planted as recommended for each crop. The experiment was laid out in a strep plot design in three replicates. Results could be summarized as follows: All characters of maize was significant by affected increasing soil tillage depth from 15 up to 20 cm depth except, plant height in first season. On the other hand, maize grain yield recorded the highest value with tillage depth at 20 cm in both seasons. Maize pure stand recorded the highest values of all studied characters followed by planting in beds and the lowest values were obtained, when maize grown in ridges in both seasons, except, plant height behaved opposite trend of these characters. indicated that plant height in the second season, No. of kernels, ear weight-1, 100-kernel weight in the first season and maize grain yield fad-1 in both seasons were significantly affected by interaction between plowing depth and intercropping patterns. Also, all soybean characters were significantly affected by tillage systems in both seasons, where, tillage depth at 20 cm gave the highest values, followed by at 25 cm While, 15 cm depth gave the lowest values in both seasons. Whereas soybean pure stand recorded the highest values of yield in both seasons, followed intercropping 100% + 50% soybean on the beds in both seasons. The found that 100-seed weight and seed yield fad-1 in both seasons were significantly affected by the interaction between different tillage depth and intercropping patterns. Soil tillage depth at 20 cm and intercropping pattern (100% maize + 50% soybean) on beds recorded the highest values for LER (1.34) and LEC (0.43) in the combined analysis, which showed that intercropping had better grain yield performance when compared to sole cropping. All intercropping patterns were grown in different depths were positive for total income comparative to maize pure stand in combined analysis of both seasons. The highest total income and MAI were achieved with plowing depth at 20 cm in beds (8855.96and 2247.03 L.E. fad-1 ) and the lowest value was showed with plough at 25 cm in ridge (6426.63 and 126.01L.E.fad). Growing maize and soybean with plowing depth at 20 cm increased total income by 10.26 and 10.70%, while MAI increased by 0.88 and 28.80 % compared with plowing depth 15 and 25 respectively. It could be concluded that tillage at 20 cm depth and intercropping pattern (100% + 50%) maize/soybean planted in beds to obtain the best land usage and total income. | ||
