Growth and p uptake of maize at various p levels under AMF inoculation and different planting methods

Inayat Ullah Khan and Inamullah

Immobility of phosphorus (P) in soil and its poor availability to crops is a matter of serious concern as it severely affects crop growth, yield and net income of farmers. Application of arbuscular mycorrhizal fungi (AMF) and suitable planting method (PM) may enhance P availability to crops. Experiments were conducted to investigate the growth and P uptake of maize in the presence of AMF and different PM during two consecutive years i.e. 2016 and 2017 at the University of Agriculture Research Farm Peshawar-Pakistan. Three different PM, viz. flatbed, raisedbed and ridges sowing, five levels of P (as P2O5) (0, 30, 60, 90 and 120 kg/ha), with or without AMF inoculation were used. Higher plant stature (PS), leaf number per plant (L/P), leaf area index (LAI), SPAD value, crop growth rate (CGR) and absolute growth rate (AGR) of maize were achieved with the application of P @ 60 kg/ha. However higher specific leaf area (SLA) was achieved with P @ 90 kg/ha and total P uptake (TPU) with P @ 120kg/ha. PS, L/P, LAI, SPAD value, SLA, CGR, AGR and TPU were significantly higher with the application of AMF to the field. Higher PS, L/P, SPAD value, CGR and ABR were recorded with both raisedbed and ridge PM. Higher SLA and TPU were recorded with raisedbed PM while higher LAI was recorded with ridge PM. It was concluded that AMF application and P @ 60 kg/ha improved growth of maize. TPU is improved with AMF application and P application @ 120 kg/ha. Among the planting methods, both raisedbed and ridge planting methods improved growth of maize.
