摘要

Wheat (Triticum aestivum L) residue removed, burnt, or incorporated with or without 0, 60, and 120kg nitrogen (N) ha(-1) effects on maize (Zea mays L) hybrids (Pioneer-3025, Pioneer-30P45, and Kiramat) were assessed at University of Agriculture, Peshawar, Pakistan during 2010 and 2011 for maize production and soil carbon (C) storage. Pioneer-30P45 had higher grain yield, leaf area, and delayed maturity. Residue burning combined with 120kg N ha(-1) produced higher grain yield. The leaf area, leaf area ratio, grain N content, and solar radiation interception were improved with N + residue burnt/incorporated over control. The grain yield was positively correlated with yield parameters. Soil organic carbon (SOC) content were in order of incorporated & burnt & removed at all growth stages (i.e., sowing, tasseling, maturity, and harvesting). Conclusively, wheat residue burnt/incorporated into the soil with 120kg N ha(-1) was best for maize production of Pioneer-30P45; however residue incorporation into the soil improved SOC.
