Antifeedant, malformations, and growth inhibition induced by leaves and seeds methanolic extracts of Solanum elaeagnifolium against Spodoptera littoralis were investigated. Seeds and leaves extracts were added to an artificial diet which was found to have an inhibitory effect on the growth of the larvae. The highest growth inhibition was recorded on larvae treated with seeds extract (59.68%) c ...

Fulvic acid is a natural tampon and an appropriate chelating agent that has high ion-exchange ability and increasing absorption of minerals in plants. This paper examined the effects of extractants (sodium hydroxide, sodium polyphosphate, urea and EDTA) and the extraction time (1, 7 and 9 days) on the physicochemical properties of vermicompost-produced fulvic acid. Finally, various methods wer ...

A field experiment was conducted based on randomized complete blocks design (RCBD) in three replications during 2011 at the research farm of university of Tabriz, Iran. In this study two medicinal plants, dill (Anethum graveolens L.) and fenugreek (Trigonella foenum-graecum) intercropped at different additive (1:20, 1:40 and 1:60) and different replacement (1:1, 1:2 and 1:3) series. Results sh ...

The current research was carried out to investigate field performance of three maize cultivars (S704, BC678 and H500) under non-stressed (performing 50 mm evaporation from class A evaporation pan) and stressed (performing 90 mm evaporation from class A evaporation pan) conditions at grain filling phase. Results showed that water stress during grain filling stage mainly had effects on grain wei ...
