Applying the gompertz and logistic equations to compare the tomato yield affected non-living mulches (organic and inorganic) and metribuzin

In order to comparison of effects of non-living mulches (organic and inorganic)and metribuzin on tomato yield, gompertz and logistic equation were used in aconducted trial at the College of Agriculture, Shiraz University in 2012. Resultsof this study showed only gompertz model were effective for calculating ofpercentage of the predicted yield for each treatment. Also, starting of weedinterference with crops was the only differentiation aspects between treatments.According to the experiment, plots treated with non-living mulches especiallyinorganic mulches, showed higher yield than metribuzin as a chemical controlof weeds.
