this research was conducted under greenhouse conditions to evaluate the optimum combination of irrigation and fertilizer levels to attain the best yield and quality of tomato crop. the experiment was conducted by using a split-plot design with three replicates. irrigation levels were applied to the main plots and fertilizer levels to the sub-plots. for each experimental unit, the irrigation lev...
In order to evaluate the growth function of Populus nigra trees under homogeneous conditions, a total of 24 individuals of P. nigra (3 individuals per stand) were sampled from 8 artificial stands in Kermanshah province and 12 individuals of P. nigra (3 individuals per stand) were sampled from 4 artificial stands in Zanjan province. In order to assimilate environmental conditions, seedlings were...
The rapid population growth and the need for more agricultural production necessitate more attention to water shortage and enhancing water productivity. To assess water productivity and supply:demand ratio index in sugar beet, this experiment was carried out using SUCROS growth simulation model. Long-term climatic data and collecting questionnaires from farmers were used to assessing water prod...
in order to investigate the effect of irrigation and nitrogen fertilizer on yield and yield components of (anethum graveolens l.), a field experiment was performed in agricultural research farm of the university of tabriz, iran, during growing season of 2009-2010. the experiment was carried out as split plot based on randomized complete block design with three replications. irrigation treatment...
many of precision farming studies have shown a high plant-to-plant variability for many crops. this study was conducted to evaluate the plant-to-plant variability of three medicinal crops in comparison with corn as a long term commercial species. thus a field experiment was performed in 2009-2010 in ferdowsi university of mashhad, research farm. in this experiment plant morphological characters...
little information is available on the effects of applying compost tea to species in dry regions. compost from agricultural waste can promote drought resistance in plants and increase their growth by improving soil structure and providing nutrients and enhancing the capacity of the soil to store moisture. in order to examine these effects, compost tea was tested on two species growing in dry re...
Field population densities of Ditylenchus dipsaci associated with shoot tissue of Phlox subulata were monitored during two consecutive growing seasons and intervening periods of overwintering and plant storage. The population density increased significantly through four peaks during the first growing season, and decreased significantly during storage at 5-7 C or overwintering in the field. Duri...
Different responses of plant genotypes to the change of environmental conditions have been the most important and challenging issue for plant breeders and agronomists for the selection of superior genotypes. Cumin is one of the most important medicinal and aromatic plants in Iran that are strongly affected by varying environmental conditions. This study was aimed to investigate E×SD interaction...
