| Abstract | ||||
| Field experiment was conducted at Sids Horticulture Research Station, in Beni-Suif Governorate in 2018 and 2019 summer seasons to study the effect of intercropping sesame (Shandaweel-3) with hybrid tomato (Nema 1400) in three intercropping patterns 100% tomato + (50%, 33% and 25% sesame) in addition solid planting of both crops under three sowing dates for sesame was also studied the effect on plant growth, yield attributes and yield of both crops. The experiment was implemented in a split plots design with three replications. The main plots were devoted to the previous three intercropping dates, whereas, the sub-plots were allocated to the intercropping patterns of sesame with tomato. Results indicated that intercropping patterns increased all growth characteristics and yield of tomato compared with solid planting. The yield and its components were significantly affected by different intercropping patterns in both crops. The highest tomato yields (26.033, and 27.303ton fed.-1) in the first and second seasons, respectively, were obtained when sesame was planted before tomato by 15 days for tomato with 50% from density (CS1) pattern. However, the highest yield of sesame (2.83 and 3.60 ardab per fed.-1) in the first and second seasons, respectively, was obtained when sesame plants were grown before tomato by 15 days and 50% from total density, whereas, the lowest value was recorded at CS3 pattern (1.52 and 1.82ardab fed.-1), respectively. Maximum values of total land equivalent ratio (LER) (1.62 and 1.63), were observed with CS1in both seasons, respectively. The data indicated that tomato was dominating in the first date when sesame planting before tomato by 15 days. The total or net return showed that intercropping sesame with tomato by 50% from total density were higher (LE. 41954 and 44706) compared to solid tomato (LE.32108 and 33296) or solid sesame planting (LE. 5161 and 7991). Therefore, it is recommended to grow sesame before tomatoes by 15 days, at a distance of 10 cm between gores and one plant in the grove (with a density of 50% of the total density of sesame) to obtain the highest productivity of tomato crops and the highest economic return to farmers. | ||||
