Regarding the public concerns about serious health risks from pesticide, the occurrences of 105 pesticide residues including Organochlorine, Organophosphorus, Organonitrogen, Dicarboximides, Strobilurin, Triazine, Pyrethroids were assessed using a descriptive method in 25 fresh and greenhouse vegetable samples (fresh carrot, greenhouse tomato and cucumber). Ethyl acetate was used for extraction...

The aim of this study was to evaluate the factors affecting the attitude of cucumber and tomato greenhouse farmers toward production of healthy crops in Isfahan County. Data were collected on a sample of 110 farmers through face-to-face interviews based on a comprehensive structured questionnaire. Validity and reliability of the questionnaire was initially evaluated on a pre-test study respecti...
The scope of the study was average climate impact tomato, cucumber, and lettuce produced in heated greenhouses. functional unit one kilogramme final product at farm gate. Comparable data sets were used situation 2004 2017. Main finding that changes energy profiles, especially increasing contribution renewable instead fossil ones, remarkably decreased vegetables. greenhouse tomatoes has declined...
Greenhouse technology intensively increased in Gaza Strip and used large amounts of insecticides and fungicides for pest control. This created toxicity symptoms among farmers. This study characterized the acute toxicity of applied pesticides among farmers working in greenhouses. The study based on data collection from 57 greenhouse farmers, blood collection for acetylcholine esterase determinat...
Background and Objectives: Greenhouse cucumber is one of the most important summer crops of Iran. Quality of the product is immediately lost after harvest due to physicochemical changes. Thus, use of special pre-processes (especially use of edible coating) to delay their maturity and increase the shelf-life of the product is important. Materials and Methods: To decrease weight loss, preserve nu...
Today Grafting is important because of its advantageous in increasing plant resistance to temperature stress and salinity in Cucurbitaceae. In order to investigated the effect of grafting of Cucumis sativus var. Super daminos on babol and Cucurbita moschata var Ferro and Cucumis sativus collected in Isfahan comparing with non-grafting and self grafting of Cucumis sativus var. Super daminos as a...
To study nitrogen contribution to cucumber derived from fixation of Paenibacillus polymyxa WLY78. The nif gene cluster deletion mutant (?nifB-V) WLY78 was constructed by a homologous recombination method. effects plant-growth promotion were investigated greenhouse experiments. estimated 15N isotope dilution method (also being called the natural abundance technique). Deletion P. resulted in comp...
This experiment was performed to investigate the effect of some Trichoderma spp. isolates as growth promoters of cucumber (Cucumis sativus L.) seedlings under greenhouse conditions. Inoculai of 19 Thrichoderma spp. isolates were prepared from disinfected wheat grain. The upper half of the soil in pots (containing field soil and sand) was mixed with these inoculai at 3% ratio and the pots were i...
The rationale for the need to improve greenhouse complexes using energy-saving technologies growing vegetable products, including cucumber, is presented. purpose of work justify use modern electrical in protected ground structures increase productivity cucumber. Based on objectives study, following tasks were identified: analysis operating modes equipment identify ways its and reduce energy cos...
