Estimation of weed dry biomass and grain yield as a function of growth and yield traits under allelopathic weed management in maize Planta Daninha
MAHMOOD,A.; KHALIQ,A.; IHSAN,M.Z.; NAEEM,M.; DAUR,I.; MATLOOB,A.; EL-NAKHLAWY,F.S..
Growing concerns about toxicity and development of resistance against synthetic herbicides have demanded looking for alternative weed management approaches. Allelopathy has gained sufficient support and potential for sustainable weed management. Aqueous extracts of six plant species (sunflower, rice, mulberry, maize, brassica and sorghum) in different combinations alone or in mixture with 75% reduced dose of herbicides were evaluated for two consecutive years under field conditions. A weedy check and S-metolachlor with atrazine (pre emergence) and atrazine alone (post emergence) at recommended rates was included for comparison. Weed dynamics, maize growth indices and yield estimation were done by following standard procedures. All aqueous plant extract...
