Abstract

A field trial to investigate the feasibility of using water extracts of allelopathic crops viz. sorghum and sunflower as a natural weed control approach for wheat crop, was carried out during Rabi 1995-96. Mature sorghum and sunflower herbage were used for preparing water extracts. The water extracts in 100% and 50% concentrations, were sprayed 30 days after sowing of wheat crop while control plots received no spray. Spraying sorghum and sunflower 100% water extracts decreased total weed dry weight up to 53% & 53% and they suppressed biomass of individual weed species as Rumex dentatis 74% and 73%, Chenopodium album 38% and 26% Coronopus didymus by 62% and 42% and Fumaria parviflora by 40% and 33%, respectively. Sorghum 100% extract increased wheat grain yield by 14% while sunflower 100% extract by 7%.
