Effect of Mycorrhiza Fungi, Preceding Crops, Mineral and Bio Fertilizers on Maize Intercropping with Cowpea

One filed experiment was carried out to study the effect of Arbuscular Mycorrhiza fungi and three preceding winter crops, i.e., Meskawy cultivar Egyptian clover berseem (Trifolium alexandrinum L.), Careem sugar beet (Beta vulgaris) Sakha 94 wheat (Triticum aestivum) five fertilizer combinations as treatments NPK mineral bio which included 100% (T1), 75% + arbuscular mycorrhiza (AMFs) (T2), 50% (T3), mycrobein (T4) (T5) on maize intercropping with cowpea. The results showed that best a crop gave highest values cowpea, followed by crop. While recorded lowest values. Fertilizer had significant all cowpea traits. treatment (T2) Meanwhile, no differences were found between T1 (100% mineral) T2 (75% (AMFs)) combination studied characters maize. interaction most in two growing seasons. cultivation components after Mixing third cut straw increased significantly quality digestibility forge both Planting yield advantageous for land equivalent ratio (LER) relative crowding coefficient (K) 1.51 1.6 9.45 15.35 first second seasons, respectively. increases net return 3955.67 5062.50 L.E., equates percentage 34.25 44.71%, component compared pure stand
