low seed germination and seedling emergence is one of the main problems in saline areas. seed priming technique has been known as a challenge to improve germination and seedling emergence under different environmental stress. the objective of this research was to evaluate the effect of seed priming with gibberellin, nacl and water on seed germination and seed reserve utilization and germination...

a field experiment was conducted in research farm of isfahan university of technology, isfahan, iran in 2011 . various weeding periods were investigated on growth and yield of potato under drip tape and furrow irrigation systems. a split plot arrangement was used in a randomized complete block design with three replications. irrigation treatments were included in main plots and periods of weed ...

to inspect the effect of methyl salicylate (mesa) vapor on fruit shelf life quality in kiwifruit (actinidia chinensis cv. hayward) an experiment was carried out in citrus research institute, ramsar, iran in 2006-2007. the experiment was based on a completely random design of three replications. the treatments consisted of mesa at five rates (0, 8, 16, 24 and 32 µl/l) and storage time of five le...

in this study two intelligent systems, based on adaptive neuro-fuzzy inference systems (anfis) and artificial neural networks (anns) of forecasting municipal solid wastes (msw) generation has been proposed. anfis and anns as an intelligent tool compared with together was used to monthly prediction of msw generated in tehran. monthly amount of solid wastes (sw), total monthly precipitation, mont...
