A study was conducted to investigate the intercropping of legumes with cereals in different space as an approach to improve the soil nutrient content, the forage quality and the yield of cereals. Black locust was cultivated alone and intercropped with maize as follows: 2 rows maize to 2 rows Black locust (2M2R), 2 rows maize to 4 rows Black locust (2M4R), 2 rows maize to 6 rows Black locust (2M6R); 4 rows maize to 2 rows Black locust (4M2R), 4 rows maize to 4 rows Black locust (4M4R), 4 rows maize to 6 rows Black locust (4M6R) and 6 rows maize to 2 rows Black locust (6M2R), 6 rows maize to 4 rows Black locust (6M4R), 6 rows maize to 6 rows Black locust (6M6R).The experiment was laid out in randomized complete block design with three treatments and three replications. The results indicated significant increase of soil available phosphorus and soil organic matter in 2017 at harvest, while soil total nitrogen and soil available potassium decreased. However, total nitrogen and organic matter were higher in black locust leaves, black locust stems and maize stem.
Low maize yield were founded in the major part of treatments while the highest biomass was founded in plants stem diameter. An increase is observed in maize and black locust height. Significant differences were founded in the character of black locust stem basal diameter. Also, significant differences in Chlorophyll concentration and WUE were observed.
