| Abstract | ||||
| The main objective of this study is using the mulching rice technique with degradable materials (paper) as an environmentally friendly method to suppress rice weeds in transplanting rice fields without using any contaminating herbicides. This experiment was done using three different colors of degradable mulching papers (White, Gray, and Brown), each color with two different masses (120 and 180 g/m2) were used as mulching paper materials to cover experimental plots, compared with the uncovered plot with using herbicide treatment and control treatment of uncovered plot without using any herbicide. The obtained results revealed that using rice mulch paper was found to be very effective in weed suppression. Using any given color of mulching paper (180 g/m2) give the highest value of weeding efficiency (100%) and highest useful life period (90 days) of mulching paper, compared with (95.97%) and (90 days) for mulching paper of 120 g/m2. While the herbicide treatment gave the lowest value of weeding efficiency (76%). The values of dehydrogenase enzyme activity and the related total amounts of nitrogen (N); potassium (K), and phosphorus (P) were increased from 1st stage to 2nd stage and from 2nd stage to 3rd stage and then decreased from 3rd stage to 4th stage again for any given study parameters. The mulching treatment of covered plot with paper gray, 120 g/m2 produced the highest value of grain and straw yield of 5.265 and 6.696 ton/fed., respectively, and gave the best results of grain quality. | ||||
