Title INFLUENCE OF NITROGEN SOURCES INCORPORATED WITH A RANGE OF TILLAGE IMPLEMENTS ON WEED INFESTATION AND MAIZE YIELD
AuthorsMehran Ali and Inamullah
Abstract

To measure the impact of tillage implements and the incorporation of various N sources on maize yield and its weeds, a field experiment was conducted at Agronomy Research Farm, The University of Agriculture Peshawar during summer 2016. The design was used randomized complete block design with split plot arrangement having four replications. Tillage implements were considered as main plot factor with total of four types (Mould board plough, Rotavator, Disk harrow and Cultivator). N sources(Control, Cattle manure, Poultry manure, Sheep manure, Mushroom spent, Mungbean residue and Urea) were allotted to subplot. The results exhibited that, lowest weed density (178 m-2), fresh weed biomass (256.4g m-2), dry weed biomass (76.7g m-2) while higher mean single leaf area (360 cm2), grain yield (3522 kg ha-1), and stover yield (7247 kg ha-1) were recorded with application of N under mould board plough tilled treatments. Among differentN sources urea performed better but statistically non-significant with organic sources. The decreasing trend among organic sources for grain yield was poultry manure > sheep manure > mushroom spent > cattle manure > mungbean residue. Conclusively, organic sources incorporated with MB plough could be better alternate for urea to improve maize productivity and soil fertility on sustainable basis if the availability of organic fertilizers are not limited.
