Abstract

To study the effect of humic acid and crop residues application on wheat, an experiment was conducted at New Development Farm of KPK Agricultural University Peshawar during winter 2011-12. The experiment was laid out in RCB design having four replications. A plot size of 3 x 4m was used. Pirsabak2005 variety was used. Different level of Humic acid @ 1, 1.5, 2 and 2.5 kg ha-1 was applied at sowing time 5 tons ha-1 of mungbean, 10 tons ha-1 of wheat straw and 21/2 and 5 tons ha-1 of mungbean and wheat straw was incorporated 30 days before sowing. Results revealed that higher days to anthesis (125), days to maturity (157) and plant height (84.6 cm), were recorded from those plots where 2.5 kg ha-1 of humic acid was applied, whereas 5 tons ha-1 mungbean incorporation gave us higher anthesis (123.8), days to maturity (157) and plant height (85.7 cm). It is concluded that 5 tons ha-1 of mungbean residues incorporation and 2.5 kg ha-1 of humic acid application will lead to good vegetative growth.
