Description |
The present experiment entitled, “Screening of pearl millet [Pennisetum glaucum (L.) R. Br. Emend. Stuntz] genotypes for weed suppression potential” was conducted at Students Farm, Department of Agronomy, CCS Haryana Agricultural University, Hisar, during kharif season 2005. Seventeen pearl millet genotypes were tested in randomized block design with three replications to find out their weed suppressing ability and for laboratory studies root extracts of pearl millet genotypes was tested on Trianthema portulacastrum (weed) in complete randomized design with six replications to determine effect on weed germination, root length, shoot length and dry weight. Of the 17 genotypes of pearl millet screened for their suppression potential on weeds, six varieties viz. HHB-117, HHB-67 Improved, HHB-146, HMP-204, HMP-205 and HHB-67 significantly suppressed the growth and drymatter of weeds. The maximum plant height and dry mater plant-1 at harvest were recorded in Local race (Shyampura, Rajasthan).Highest grain yield was recorded in HHB-117 which was at parxxiwith other genotypes except HHB-50, HC-10, HMP-206, Local race (Sardar Sahar, Rajasthan) and Local race (Phoga, Rajasthan). The aqueous extract of pearl millet roots, inhibited the germination, root length, shoot length and dry weight of Trianthema portulacastrum (weed) as compared to control. The results are very encouraging for non-herbicidal control of weeds hence, more research may be done in this direction. |
