Effect of Intercropping Between Corn (Zea mays) and Peanut (Arachis hypogaea) with Arbuscular Mycorrhizal (AMF) on the Yield and Forage Mineral Content

The study aimed to analyze the cropping pattern of intercropping between maize plants and peanut with arbuscular mycorrhizal fungi inoculated on yield and mineral content of forage. Field experiments used a split plot design with main plots were intercropping patterns (TS) consist of three kinds: TS 1:1 TS 1:2 and TS 2:1. The subplots were the single AMF inoculation consisted of four kinds: m, (Glomus. etunicatum), M2 (Glomus manihotis). m3 (Gigaspora margarita) and m4 (Acaulospora sp). The experiment was replicated three times, then the number of plots were 36. Agronomic parameters measured were fresh weight of corn crop and fresh weight of baby cam residues, calcium content of corn plant and of baby corn residues, calcium content of peanut plant, phosphorus content of Corn plant with baby corn residues and phosphorus content of peanut plants. The experimental results showed that: (1) The effect of the initeraction did not occur between the cropping patterns of intercropping system with a single AMF inoculation on yield and forage minerals. (2) The content of Ca (calcium) and P (phosphorus) of corn crop with baby corn residues on the cropping pattern of intercropping system with FMA inoculated were the sealer Ca on TS 1:1 (0.51%), TS 1:2 (0.57%) and TS 2;1 (0.47%) and the content of P (phosphorus) in the TS 1:1 (0.14%), TS 1:2 (0.15%) and TS 2:1 (0.14%). (3) The content of Ca (calcium) of peanut plants at planting pattern of intercropping systems with FMA inoculated at TS 1;2 (1,65%) and 2;1 (1.76%) were higher than at TS 1:1 (1.45%), while the content of P (phosphorus) were similarly at TS 1:1 (0.162%), TS 1:2 (0.184%) and TS 271 (0.169%). (4) The fresh weight of corn crops together with baby corn residues an the cropping pattern of intercropping system with FMA inoculated were equals; TS 1:1 (36,36 tones/ha/harvest), TS 1;2 (32,75 toneslhaiharvest) and TS 2:1 (35.66 tonesihatharvest). The peanut plant fresh weights were not significantly different among TS 1:1 (3.g9 tones.ohaiharvest), TS 112 {6.70 tones/ha/harvest) and TS 2:1 (2.30 tonesitarharvest). Providing a single AMF inoculation has no effect on fresh weight, Ca and P of groundnut and of maize crops together with baby corn residues.
