Soil solarization is a technique used for weed control in regions with high level of solar radiations. Soil solarization for 35 or 45 days decreased the emergence of annual weeds by over 90 %. Emergence of Cyperus rotundus from tubers was increased by soil solarization. Furthermore, seed germination of Commelina benghalensis was increased by soil solarization. The main solarization effect was restricted to 0 - 5 cm layer of the soil. The maximum temperature at 5 cm depth was about 8 - 10°C warmer in solarized soil than in control plots. It was concluded that soil solarization with transparent polyethylene film for 35 or 45 days caused healthy seedling of brinjal by increasing the dry matter production of seedlings and proved very useful technique for controlling more than half of the weed species recorded without any use of chemical.
