The study looked at how different ways of managing weeds affect the growth and yield of wheat and rice crops in Jammu. They tested various methods like using chemicals or manual weeding to control weeds. They found that when there were more weeds, the crops didn't grow as well and produced less yield. In wheat fields, common weeds included Medicago denticulata and Anagalis arvensis, while rice fields had Cyperus rotondus and Cynodon dactylon. Overall, keeping weeds under control is important for getting good harvests of wheat and rice in this region.
