Mulching and herbicidal treatment response was studied for two consecutive years to check their effect on weed growth, flowering behavior, fruit characteristics and yield of low chilling peach cultivar Shan-e-Punjab under sub-tropical conditions. Among fourteen treatments including different mulches and herbicidal concentrations, black polythene mulch recorded zero population of weeds and weed dry matter after 30, 60 and 90 days of treatment. Highest weed control efficiency and lowest weed index of 3.09 percent was observed with black polythene mulch treatment. Among tree characters, highest annual shoot extension growth (45.20 cm), leaf area (37.20 cm2) and increase in tree volume (37.96 m3) was recorded with black polythene mulch. Black polythene mulch was found to be superior as compared to other mulching material in term of yield attributes as it registered highest fruit set of 65.20 per cent, minimum fruit drop (30.11%) and highest fruit yield of 56.40 kg per tree. Fruits produced on tress having black polythene mulch had highest fruit weight (90.41 g), fruit length (5.90 cm), fruit diameter (4.84 cm), fruit volume (90.40 cm^-3), pulp weight (83.29 g) and pulp: stone ratio (11.70), followed by the fruits produced on the trees treated with 2.0 kg a.i ha-1 Atrazine. Black polythene mulch also proved superior in term of chemical fruit characteristics such as total soluble solids (12.25o B), vitamin C (6.97mg 100g^-1 pulp), total sugars (9.52%), reducing sugars (5.14%) and nonreducing sugars (4.16%) in comparison to rest of the treatments.
