Abstract

A field experiment was carried out on 2018/2019 and 2019/2020 at Sids Horticultural Research Farm, Egypt. To study the effect of some herbicide, mulches and their combinations on tomato productivity and associated weeds. A field trial included: a) mulches (rice and wheat straw), b) herbicides (Stomp extra at 1.7 L./fed. and Sencor at 300 g./fed.) either both at full rate alone or at reduced rate 50% of full rate with their integrated by mulches (rice or wheat straw), beside, hand hoeing ,three times and weedy check. A experiment was laid out in a Randomized Complete Blocks Design with three replicates. The results revealed that the all combinations between the two herbicides (Stomp extra at 0.850 L. and Sencor at 150 g./fed.) followed by mulches rice or wheat straw were superior on weed control efficacy than either the herbicides at full rate alone, or mulches alone without any significant differences between all these combinations. But Sencor 150 g./fed. combined with mulching rice straw gave higher weed efficacy than stomp extra combinations with rice or wheat straw in both seasons. It's noticed a positive correlated between weed control efficiency, improving vegetative growth traits and higher tomato fruit yield and its components. Therefore, the combination of Sencor at 150 g./fed. with rice straw can be used as alternative safety methods replaced by either herbicides Sencor and Stomp extra at full rate alone or mulches alone to achieve weed control efficacy without loosing tomato fruit yield, quality and its components.
