摘要：Natural resources are the most limiting factors for sustainable agriculture in Pakistan. Traditional tillage (intensive tillage) has undesirable impacts on soil properties and crop productivity. Incorporation of residue/residue is used effectively in many countries such as Australia, America and China, where many characteristics of the soil like soil water holding capacity, soil fertility and soil structure have improved. The goal of this study was to assess the physico-chemical soil properties by residue incorporation with tillage management (conventional and reduced tillage). An experiment was laid two years (20162017) continuous cropping intensity with 04 treatments (T1 conventional tillage, T2reduced tillage, T3 conventional tillage+ wheat residue 02 ton.ha1, T4 reduced tillage+ wheat residue 02 ton.ha-1). Moreover, ECe of soil, pH, Bulk density and organic matter were observed at 0-15, 15-30 and 30-45 cm, pre and post harvesting of crop. Further, result revealed that the maximum decrease in EC (12.50%), pH (8.5-7) and soil bulk density (9.79%) were observed in T3 at depth (0-15 cm). The average soil organic matter was significantly (P<0.05) increased in all treatments, but the maximum (0.53-0.60 %) was in T3 at depth (0-15 cm) followed by T1, T4, and T2 as 0.57, 0.57, 0.54% respectively. Total grain yield was found greatest in T3, (11.61 ton.ha-1) and least were observed under T2 (6.91 ton.ha-1). It can be suggested that conventional tillage with wheat residue incorporation (T3) may be laid for favourable soil management tool to improve the soil fertility, soil bulk density and maize crop production.
