Strawberry plants of Oso Grande variety has been treated with three types of foliar fertilizers containing (Nitrogen, Boron, Manganese) individually and combined, in addition to treating some of them using urea as soil fertilizer. Some plants were untreated to be used as a control. Three concentrations were used.

This research aims to study the effect of Gebbrilin compounds, specially GA٣, on the percentage of germination of seeds in different concentrations and duration, Also the effect of this compound on the growth of the root cells and so on the cellul ar division. It was observed from the results that these compounds had an evident effect on the degree of germination within the low concentration, but it has an opposition effect in the high concentrations. The results concerning the growth of the roots are analogous to those of the germination results. An obvious difference was in the reaction of wheat and barley to the different concentrations of GA٣. For the mitotic index no differences were observed compared to the control.
We studied in this research the systemic activity of fungicide carbendazim in cucumber plants (Hybrid F1 Milton). The soil was treated with fungicide with concentrations of 0.25 - 0.5 - 1.0 - 2.5 g active ingredient per kg of soil and the month-old plants was sprayed (three true leaves) with the recommended concentration 0.25 active ingredient per liter of water, half and double of concentration. Bioassay method was used to detection the systemic activity of fungicide by putting the plant parts in direct contact with sensitive fungus spores within petri dishes that containing PDA. It has been detected the presence of carbendazim in the root , cotyledonary leaves and first real leaf after 20 days from treatment the soil for all concentrations, as it was observed the fungicide persistence in plants after forty days. In the spraying treatment, It has been detected the presence of carbendazim after one day for all concentrations and for the recommended and double concentration only after five, ten and twenty days of spraying.
