Under P.E. mulch, the number of weeds was higher, but the weed dry weight was lower than in bare soil by the middle of July. Sixty days after seeding, the length of main stems in weedy check plots was longer, but shoot dry weight was lower compared with weed free plots. In the correlation coefficients between weed dry w2048eight and the shoot dry weight of peanut on July 14, the growth retardation of peanuts due to weeds was shown earlier under P.E. mulch than in bare soil. Shoot dry weight, shelling ratio, number of seeds per pod, 100 pod weight, and seed yield were higher under P.E. mulch compared with bare soil. But weed dry weight, length of branches, number of pod bearing branches, number of pods per square meters, and pod yield were similar between P.E. mulch and bare soil. Shoot dry weight of peanuts, length of branches, number of pod bearing branches, number of pods per square meters, pod yield, 100 pod weight, 100 seed weight, and seed yield in weed free plots from 28 days after seeding to harvest (28 DAS-Harvest) were higher compared with weed free plots from 42 DAS-Harvest. However, in the weed free plot from seeding to 42 days after seeding, seed yield was lower than that of the continuous weeding plot due to lower number of pod bearing branches and number of pods per square me
