Abstract
The experiment was conducted at experimental site of chandigarh University Gharuan (Mohali) during Rabi season of 2020-2021. Twelve treatments comprising Topik (333 and 400 g ha-1), Pumasuper (600 and 800 g ha-1) Sulfosulfuron (26.6 and 33.3 g ha-1), Sencor (200 and 250 g ha-1), Grasp (3500 g ha-1), Isoproturon (1000 g ha-1), Weed free and weedy check were tested in a randomizeci block design with 3 replication. Phalaris minor Retz, Medicago denticulata, Auagallis arvensis L., Fumaria parviflora L., Lathyrus aphaca L. and Vicia sativa L. were the predominant weeds present in the experimental field. Among the various weed control treatments weed free and sencor at 200 g ha-1 and 250g ha-1 give significantly higher grain yields of 45.88, 45.31 and 43.86 q ha-1 respectively and were at par with one another. These treatments had significantly higher number of effective tillers and larger ear length which exhibited more number of grains per earhead and higher test weight as compared to rest of treatments. Application of grsap at 3500g ha-1 was next in superiority but produce significantly lesser grain yield as compared to weed free and sencor at 200 g ha-1 and 250 g ha-1 due to lesser weed control efficency and proved to be statistically superior to rest of the treatments. Application of Sulfosulfuron (26.6 and 33.3g ha-1) indicated significant reduction in grain yield of wheat as compared to weed free, Sencor (200 and 250 g ha-1) and isoproturon (1000 g ha-1) due to lesser control of broad leaved weeds. However, Topik (333 and 400 g ha-1), Pumasuper (600 and 800 g ha-1) and Grasp (3500 g ha-1) remained completely ineffective against broad leaved weeds and recorded significantly lower grain yield than other weed control treatments.
