Abstract
A field experiment was conducted to study the effect of weed management treatments on growth and yield of tomato (Lycopersicon esculentum L) at Western block, Horticultural College and Research Institute, Periyakulam during summer season of the year 2019. The experiment was carried out in randomized block design with eight treatments and replicated thrice. Application of black polythene mulch (60% 6000 m2/ha) gave maximum control of weed by lowering the weed density, weed biomass and higher weed control efficiency (98.9%). This was followed by rice straw mulch 5 t/ha which recorded weed control efficiency of 98.5 %. Black polythene mulch recorded significantly higher fruit yield (28.1 t/ha) and recorded higher net returns (₹ 1, 90,630/-) and the BC ratio (3.11).
