Abstract


A two-year study was carried out at Sids Agricultural Experiments and Research Station, ARC, Beni Sweif governorate, Egypt, during 2012/2013 and 2013/2014 to determine the possible allelopathic effects of the preceded berseem, sugar beet and wheat crops on productivity of intercropped three maize cultivars with soybean. Three local maize cultivars (S.C. 122, T.W.C. 310 and Giza 2) were grown in alternating ridges (2:2) with one local soybean cultivar (Giza 22) after three winter crops (berseem, sugar beet and wheat) as preceded crops. A split plot design with three replications was used. The results showed that berseem roots secreted biologically active chemical compounds which have a positive effect on growth and development of maize under intercropping culture. The preceding berseem appeared to be promising for maize productivity under intercropping culture. On the contrary, sugar beet and wheat residues had negative effects on maize productivity under intercropping culture. All the studied maize traits were increased after berseem cutting except number of ears/plant and number of rows/ear in comparison with those followed sugar beet or wheat. Maize cultivar S.C. 122 had the highest values of all the studied traits compared to the other maize cultivars. The interaction between the preceded winter crops and maize cultivars was significant for all the studied traits except number of ears/plant and number of rows/ear. Intercropping soybean with maize cultivar S.C. 122 that followed berseem produced 7.11 ton/ha of maize grains in addition to 1.74 ton/ha of soybean seeds were gained by intercropping.
