MWLF: 2.45 ± 0.10 cm) compared to plots without mulch (MfRP: 1.97 ± 0.09 cm, MfRC: 2.03 ± 0.05 cm, MfRMb: 1.93 ± 0.06 cm and M: 1.90 ± 0.09 cm). However, legumes had asignificant effect on maize plant diameter growth compared to bare soil (MfLf: 1.90 ± 0.09 cm). At the 45th DAP, plant diameter did not vary significantly among treatments. The largest diameter was with the MwRMb treatment (3.09 ± 0.10 cm), and the smallest diameter was with the MfRC treatment (1.78 ± 0.09 cm). When the soil was mulched, there was greater growth (MwRP: 2.95 ± 0.12 cm, MwRC: 3.03 ± 0.10 cm, MwRMb: 3.09 ± 0.10 cm and MWLF: 2.96 ± 0.50 cm) relative to the unmulched soil (MfRP: 2.90 ± 0.13 cm, MfRC: 1.78 ± 0.09 cm, MfRMb: 2.94 ± 0.50 cm and MfLf: 2.77 ± 0.08 cm). At this stage of growth, the presence of legumes influenced plant diameter (MfRP: 2.90 ± 0.13 cm, MfRC: 2.78 ± 0.09 cm, and MfRMb: 2.94 ± 0.15 cm) compared to pure maize (MfLf: 2.77 ± 0.08 cm). At the 60 th DAP, no significant difference was detected among treatments. 1 Global Journal of Science Frontier Research Volume XXI Issue VII Year 2021 9 ( D ) © 2021 Global Journals Version I Effects of Cereal-Legume Intercropping and Mulching on Maize ( Zea Mays L.)

The different components were similar. Maize stalk weights ranged from 738.50 ± 148.83 kg/ha to 1,054.00 ± 23.47 kg/ha. The best weight of stalks was with the MwRMb treatment (1,054.00 ± 23.47 kg/ha). All mulch treatments improved maize stalk weight (MwRP: 927.80 ± 81.39 kg/ha, MwRC: 941.50 ± 32.59 kg/ha, MwRMb: 1,054.00 ± 23.47 kg/ha and MWLF: 1,015.20 ± 65.35 kg) compared to treatments without mulch (MfRP:
