high yield of top quality crop is a prerequisite for profitable production of greenhouse produced cucumber. on the other hand, because of water deficit in iran it is necessary to economize in this scarce and valuable input. an experiment was carried out in the experimental greenhouse of university college of agriculture and natural resources, university of tehran to optimize water use in soil c...

Criconemoides xenoplax and Meloidogyne incognita were the nematode species most frequently associated with peach in North Carolina. Other nematodes often found in high numbers on that crop were Pratylenehus vulnus, Helicotylenchus spp., Trichodorus christiei, Xiphinema amerieanum and Tylenchorhynchus claytoni. P. vulnus and P. penetrans reproduced well on rootstocks of 21 peach cultivars tested...

Meloidogyne incognita and M. arenaria reproduction and host plant tolerance were assessed in field and greenhouse experiments on seven holly cultivars including Ilex glabra 'Shamrock', I. vomitoria 'Schelling's Dwarf', I. cornuta 'Carissa', red holly hybrid (Ilex Little Red), and I. crenata 'Compacta', 'Green Luster', and 'Helleri' as well as Japanese boxwood (Buxus microphylla) and two lantana...

Greenhouse detection and mapping via remote sensing is a complex task, which has already been addressed in numerous studies. In this research, the innovative goal relies on the identification of greenhouse horticultural crops that were growing under plastic coverings on 30 September 2013. To this end, object-based image analysis (OBIA) and a decision tree classifier (DT) were applied to a set c...

The reproduction of a Wyoming population of Heterodera schachtii was determined for resistant trap crop radish (Raphanus sativus) and mustard (Sinapis alba) cultivars, and resistant and susceptible sugar beet (Beta vulgaris) cultivars in a greenhouse (21 degrees C/16 degrees C) and a growth chamber study (25 degrees C). Oil radish cultivars also were field tested in 2000 and 2001. In the greenh...

in the present study, an attempt has been made to use data envelopment analysis (dea) for assessing the technical efficiency and return-to-scale for greenhouse cucumber production in iran. for this purpose, the data from greenhouses in esfahan province, during one period of plant cultivation in one year including spring plants were randomly collected. the results indicated that total input ener...

a precise estimation of water consumption throughout a crop's growth season and of the amount of water consumed in each growth stage may play an important role in water resources management, integrated water and soil management, and proper irrigation scheduling. in a greenhouse, this faces with the conditions specific to this environment. this study was conducted to propose a model to make an a...

The aim of the research was to determine field, greenhouse and seed bed performance of plantlets derived from in vitro propagated plantlets of three potato cultivars. Generally, higher values were obtained from the mid-early maturing cultivar Marabel, compare to other cultivars (early cultivar Velox and and mid-early cultivar Concorde) for tuber yield, tuber number and average tuber weight. For...

the purpose of this study is to evaluate greenhouse owners’ knowledge regarding integrated pest management (ipm) in the production of greenhouse cucumber in khorasan razavi province.the survey research was a descriptive – correlational one. the study consisted of all farmers who cultivated greenhouse cucumber in khorasan razavi province (n=160), of whom 108 were selected through a random sampli...

Cucumber is a species appreciated in cooking, addition to providing various nutrients for health. In view of this, it important that research on its growth carried out, prioritizing statistical analyzes effectively demonstrate the results. The objective was verify differences by analyzing variance and nonlinear models, characterizing production, early production rate cultivars cucumber using mo...
