kinds of plastic mulches. During the experiment plant height at flowering, tomatoes diameter, number of
narrow leaf weed, number of broad leaf weeds tomatoes fresh weight of, dry weight Tomatoes was
measured. Experimental treatments significant effect on the plant height at flowering did not. Experimental
treatments tomatoes diameter the influence were statistically significant at the on percent level. Narrow leaf
weeds affected experimental treatments were five percent level of statistical significance was. Experimental
