Nowadays, spraying and foliar feeding represent one of the most effective techniques of applying essential nutrient elements to crops and to optimize the application of fertilizers in agriculture. In this research, effect of foliar application of different concentrations of ammonium sulfate on quantity and quality traits of cucumber under greenhouse conditions was investigated. The research was...
Among the chemicals that their effects on reducing chilling injury has recently been studied are salicylates and jasmonates. Therefore, in this study the effects of salicylic acid and methyl jasmonate on increasing the cold tolerance of bell pepper cv. Emily was examined. Experiment was done as a 7×2 factorial in the completely randomized design (CRD) with four replications. The first factor co...
This study was conducted in Research Farm of Isfahan University of Technology to evaluate some of the agronomic and physiological traits and grain yield potentials of ten bread wheat cultivars using a split plot design with three replications. Main and sub plot consisted of optimum and stress moisture treatments (irrigation after 70±3 and 130±3 mm evaporation from class A pan) and wheat cultiva...
Salinity is one of the greatest factors that limit the producion of horticultural crops in many parts of the world, especially in arid and semi-arid areas. Tomato (Lycopersicon esculentum L.) is an annual herbacious plant whose annual global production is over 80 million tons. In areas with warm and dry climate which are suitable for the production of tomatoes, salt is considered a major proble...
in order to evaluate the effects of drought stress and planting method on some physiological and biochemical characteristics of two chickpea cultivars (cicer arietinum l.) an experiment was conducted at the research station of college of agriculture, shiraz university using a split factorial based on randomized complete block design in four replications. the main factor was stopping irrigation ...
Recent studies have demonstrated the usefulness of optical indices from hyperspectral remote sensing in the assessment of vegetation biophysical variables both in forestry and agriculture. Those indices are, however, the combined response to variations of several vegetation and environmental properties, such as Leaf Area Index (LAI), leaf chlorophyll content, canopy shadows, and background soil...
Salinity is one of major stresses which can severely limit plant production, especially in the arid and semi-arid regions. The present study was carried out to evaluate the impact of salinity stress on some physio-biochemical parameters in nitre bush plants (Nitraria schoberi). Thus, an experiment was carried out under natural conditions and salinity stress was induced by a combination of diffe...
Cantaloupe is one of the most important of vine crops in Iran that today its yield has been decreased due to reduction in the quantity and quality of water resources and also due to increased soil pH because of bicarbonate ion aggregation in the soil. In order to maintain the production quality of this plant, appropriate crop management techniques are needed. For this purpose, to investigate th...
In order to detect leaf chlorophyll level nondestructively and instantly, VIS/NIR reflection spectroscopy technique was examined. In the test, 70 leaf samples were collected for model calibration and another 50 for model verification. Each leaf sample was optically measured by USB4000, a modular spectrometer. By the observation of spectral curves, the spectral range between 650nm and 750nm was ...
abstract to investigate the effects of paclobutrazol (pbz) on vegetative and reproductive growth of strawberry cv. selva a factorial experiment in a completely randomized design with three replications was carried out in greenhouse of agriculture college, isfahan university of technology. pbz was applied in two methods, drench and foliar spray, at 0, 0.5, 1, 1.5 and 2 mg active ingredient per p...
