Soilborne pathogens and nematodes are very destructive in vegetables crops and one of the most limiting factors to farmer's income. Soil fumigation has been an essential component of greenhouses crops since the 1960s. Growing vegetables without soil fumigants has remained a challenge, in part because commercially acceptable eggplant cultivars produced through conventional breeding lack resistance to many soil borne plant pathogens. Grafting cultivars with high quality and productivity on rootstocks that are resistant to soil pests and diseases is a method known for years ago, but which was improved and quickly spread in the last years. The objective of the researches was to evaluate the performance of the eggplant grafting on the some rootstocks in greenhouse conditions, alone and in combination with soil fumigation using metham sodium. Data obtained in the combinations scion/rootstock and not grafted eggplants were compared with data recorded where the metham sodium fumigant was used and as well as with the combinations grafted eggplants planted in soil disinfested with metham sodium. The marketable yield, fruits quality, frequency and root galling index of soilborne disease and nematodes, in the experimental variants were determined and calculated. Grafting process combined with the metham sodium soil disinfestation led to significant reduction in the incidence of attack produced by soilborne disease (Fusarium oxysporum f. sp. melongenae, Verticillium dahliae) and nematodes (Meloidogine incognita).

Romania is the second world and first European plum (Prunus domestica) producer country. Almost 80% of the plum crop is used in the distilling process, for the production of "tuica" (brandy) compared to the rest of Europe, where the highest percent is used for fresh fruit market and dehydration. Obtaining quality products, especially when it comes to color, taste and texture, has represented a priority in the experiments regarding plum dehydration. A number of 10 plum cultivars have been used. Physical and organoleptic properties of the fruit have been determined 3 days after harvesting. During the experiments, using halves or a whole fruit, effects of some independent variables in the drying process have been tracked, such as: the temperature of the drying air, the speed of the hot air, the dehydration time. The experiments have allowed obtaining some optimal recommended values for the parameters of the dehydration process, which ensure a minimal duration of the process itself and a reduced energetic consumption.
