ABSTRACT
A field trial was conducted at Agronomy Research Farm (ARF) of The University of Agriculture Peshawar during summer 2016 to investigate the effect of various tillage implements and nitrogen sources on maize yield and soil organic matter. Randomized complete block design with split plot arrangement having four replications was used. Tillage implements (mould board plough, rotavator, disk harrow and cultivator) were applied in main plots while nitrogen sources (control, cattle manure, poultry manure, sheep manure, mushroom spent, mungbean residue and urea) in subplots. The results exhibited that, higher plant height (200.4 cm), grains ear-1(351), seed index (228.8 g), grain yield (3522 kg ha-1), and biological yield (10799 kg ha-1) were observed with nitrogen sources incorporated with mould board plough. In case of nitrogen sources; poultry manure (3507 kg ha-1), sheep manure (3468 kg ha-1) and mushroom spent (3450 kg ha-1) gave at par grain yield with urea (3667 kg ha-1). However, soil organic matter was significantly higher in organic fertilizer applied plots compared to urea treatments. Conclusively, organic sources incorporated with mould board plough could be better alternative urea to improve maize productivity and soil fertility on sustainable basis
