Abstract

THIS WORK was conducted during the two successive autumn ….. seasons of 2012/2014 at the Experimental Farm of El-Kassasein, Hort. Res. Station, Ismaelia Governorate, Egypt. The effect of three different of nitrogen fertilizer sources, i.e., ammonium sulphate (20.5 % N) at 390.2 kg / fed. (fed. = 0.42 ha.) botanical compost at 6.667 ton/fed. and chicken manure at 2.787 ton/fed. (each equal 80 kg N/fed.) and five biocontrol agents (Trichoderma harzianum, Trichoderma viride, mixture of Trichoderma harzianum + Trichoderma viride and Bacillus subtilis) were tested on growth and yield as well as rust disease incidence and severity of snap bean cultivars (Paulista and Xera) were evaluated under sandy soil conditions. Paulista cv. gave the highest dry weight of shoots/ plant and total yield/fed. compared to Xera cultivar. Chicken manure application increased dry weight of shoots and total yield of snap bean. Foliar application with mixture of Trichoderma harzianum + Trichoderma viride increased number of both leaves and branches/ plant, dry weight of shoots/ plant, pod length and total yield/feddan. Fertilizing of Paulista cv. with chicken manure combined with foliar application with Trichoderma harzianum + Trichoderma viride increased number of both leaves and branches/ plant, plant height, dry weight of branches, leaves and shoots/ plant, pod length and total yield. Xera cv. plants gave the lowest value of rust disease severity compared to Paulista plants. Botanical compost application recorded the minimum values of rust disease incidence and severity of snap bean plants, followed by chicken manure treatment, whereas ammonium sulphate at 390.2 kg/fed. recorded maximum values. Foliar application of snap bean plants with biocontrol agents decreased rust disease incidence and severity on leaves compared to control. Mixture of Trichoderma harzianum + Trichoderma viride decreased rust disease incidence, whereas Trichoderma harzianum decreased rust disease severity.

8 of 11 groups shown: named compounds and organisms first, then groups whose results differ (checked claim by claim), then those with positive and negative results, then the smaller groups.

Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
