Strawberry is one of the most popular and beneficial fruits in viewpoint of nutritional value which its production is increasing in greenhouse. In this study the effects of two culture media (perlite + cocopeat with 1:1 ratio or Pumice) and three concentrations of humic acid (0, 300, and 600 mg L-1) as fertigation method, on yield, number of fruit per plant, fruit weight and some of biochemi...

in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...

Calcium and potassium are essential nutrients that play a significant role in increasing yield, quality and postharvest properties of many fruits and vegetables. The role of these nutrients in improving quality and quantity of fleshy fruits is important and their interaction on plants such as cantaloupe is less understood. In this research the effects of calcium (0 and 3 g/L) and potassium (0, ...

A two-year study (2005 - 2006) was carried out to explore the effect of deficit irrigation treatments according to evaporation from a class A basin, including ET= 1 (T1), ET = 0.75 (T2), and ET = 0.5 (T3), on yield, yield components and seed yield of three varieties of watermelon (Charleston Gray, Sugar Baby and Crimson Suite) in the Varamin Agricultural Research Center of Iran. A randomized co...

This study was done to investigate and compare fruit yield, yield components, morphological traits and fruit quality of greenhouse tomato genotypes in order to use them as selection criteria. Progenies of 49 crosses of greenhouse tomato together with their 13 parents were evaluated using Randomized Complete Block Design with three replications. The highest amount of fruit yield was observed in ...

Soil amendments have been widely used in greenhouse cultivation. Cucumber, as an important summer crop, has the highest area under cultivation in the greenhouses of Iran. For this reason, in the present research, effect of applying zeolite and drought stress on cucumber growth and its fruit parameters (number, weight, length and diameter of the fruit) was investigated in a split-plots experimen...

this research was conducted in two protect and destroy region in the middle zagros, in illam province. in order to identification of ecological species group and evaluate density of regeneration, effect of many factors such as protection, vegetation, physiographic factors, physical and chemical properties of soil in study locations were studied. to achieve these purpose number of 54 plots using...
