A study of population of weed on direct seeded rice planting system / Noor Asmanizan Seman

Weed is well known as the main competitor in a rice field and excessive weed lead to the reduction of rice yield as it competes with rice in terms of space, nutrients and also as a nesting place for the pest. The composition of the weed in the rice field been identified becomes wider after the direc...
