Fertilizer efficiency directly affects the production of continuous cropping greenhouse cucumber. So analyzing the fertilizer efficiency is of great significance in providing decision-making support for fertilization of greenhouse cucumber. By establishing the DEA models of continuous cropping greenhouse cucumber and taking existing data samples as study objects, the problems of fertilizer effi...

Meloidogyne incognita and Meloidogyne arenaria are important parasitic nematodes of vegetable and ornamental crops. Microplot and greenhouse experiments were conducted to test commercial formulations of the biocontrol agent Pasteuria penetrans for control of M. incognita on tomato and cucumber and M. arenaria on snapdragon. Three methods of application for P. penetrans were assessed including s...

The greenhouse whitefly Trialeurodes vaporariorum (Hemiptera: Aleyrodidae) is a polyphagous pest in greenhouse crops. The efficacy of two entomopathogenic nematodes (EPN), Steinernema feltiae and Heterorhabditis bacteriophora, as biological control agents against T. vaporariorum was evaluated using two model crops typical of vegetable greenhouse productions: cucumber and pepper. Laboratory test...

The ovipositional preferences of two squash bug species, Anasa tristis (DeGeer) (Heteroptera: Coreidae) and Anasa armigera Say (Heteroptera: Coreidae), were evaluated in paired choice tests of different species and cultivars of plants in the family Cucurbitaceae. Females of A. tristis preferred to oviposit on the cultivar from which they were reared over three other cultivars of the same specie...

hydroponics technique accompanied by adjustment of nutrient solution seems to optimize crop production and help in establishing sustainable agriculture. in recent years, the greenhouse production of cucumber has been increased in iran, however there are just a few proper nutrient solutions employed in growing the crop. in line with this, an experiment was conducted to find the effect of various...

the effect of grafting on yield and some other quantitative and qualitative characteristics of two green¬house cucumber cultivars, namely roberto and danito grafted on five rootstocks of shintoza, kiroshintoza (cucurbita maxima × c. moschata), cucurbita maxima (c. maxima cv. goriki), fig leaf gourd (c. ficifolia cv. korodome), and bottle gourd (lagenaria siceraria) was investigated in this stud...

In this study, the effect of plant growth regulators on callogenesis and gametic embryogenesis from anther cultures of cucumber (Cucumis sativus L.) was investigated. A factorial experiment based on Completely Randomized Design with three replications was used in this study. Two cultivars of cucumber (Beta Alfa and Esfahani) were used as first factor and 11 hormone treatments including: control...

Selected cotton cultivars were evaluated for resistance to the southern root-knot nematode, Meloidogyne incognita, in greenhouse and field experiments. Cotton cultivars LA 887, Auburn 634, and NemX cotton were highly resistant to three North Carolina populations of root-knot nematode in greenhouse experiments compared to susceptible cultivars. The relative susceptibility of cultivars tested in ...

Hydroponic greenhouse-grown and store-bought cultivars of tomato (cherry and beefsteak), cucumbers, bibb lettuce, and arugula were investigated to see if they could be distinguished based on sensory qualities and phytonutrient composition. Only the more dominant sensory criteriawere sufficiently robust to distinguish between cultivars and could form the core of a consolidated number of criteria...

In order to clarify the influence of the rootstock cultivar and fruit storage on the texture of cucumber (Cucumis sativus L.) fruit, we examined the physical properties of the fruit, i.e., flesh firmness, placental firmness, skin toughness, and the crispness index. Cucumber fruits from own-rooted plants and from plants grafted onto the three rootstock cultivars of ‘Shin-tosa’ (Cucurbita maxima ...
