Green manuring, Mulching, Solarization, Stale seedbed, Weed seed bank
An experiment on evaluation of soil solarization on weed seed bank of soil was conducted in 2004 at College of Agriculture, Gwalior, in randomized block design with six non chemical agronomical weed management practices viz., solarized (45 days) non-solarized, stale seed bed, deep ploughing, green manuring and mulching by green biomass. The soil temperature recorded under solarized conditions were 43.90C and 43.80C at 10 and 15 cm depth and it was 4.60C and 4.50C higher than non-solarized soil respectively. In solarized soil total number of grassy, broad leaved and sedges weeds waslowest, while highest grasses were reported in non-solarised soil. Total number of weeds was highest in non solarized soil followed by green manuring, stale seed bed, mulching, deep ploughing and non-solarised soil. Thus soil solarization was found to be the best non chemical agronomical practice for weed management methods used resulting to lowest weed seed bank.
