Background & Aim: Nowadays, tendency to agricultural biotic product sustainable agriculture instead of chemical ‎fertilizers has been going up in all over the world. So, most pharmaceutical industries prefer to ‎use raw material which is produced from organic and stable system. Producing organic ‎medicinal plants, such as peppermint, seems important in economical, ecological and ‎bio e...

Fertilization is an important process in the growth of cocoa (Theobroma cacao L). Fertilizing usually used inorganic fertilizers. Using fertilizers continuously could degrading soil fertility. One efforts to replace was using endophytic bacteria as biofertilizers. Some are abundant healthy plant tissues. The aim this research obtain auxin-producing plants and determine effect seed immersion mic...

Effects of different levels of compost application on the amounts and percentage distribution of organic N forms in whole soils and particle size fractions were investigated. Soil samples were collected from three plots: a) F, only chemical fertilizers; b) F + LC, chemical fertilizers plus low level of compost; (c) F + HC, chemical fertilizers plus high level of compost. Each soil sample was di...

abstract in order to investigate the effects of nitrogen fertilizer levels on the yield and quality of potato, (solanum tuberosum l.) a field experiment was conducted based on randomized complete blocks design with 3 replications in the research field of the college of agriculture, ferdowsi university of mashhad. nitrogen topdress fertilizer was applied in two levels of 100 and 150 kgn.ha-1 and...

1 This study examines b1-, b2and b3-adrenoceptor (AR)-mediated responses, mRNA levels and radioligand binding in ileum from b3-AR knock-out (7/7) (KO) and wild type (+/+) (FVB) mice. 2 In KO and FVB mice, SR59230A (100 nM) (b3-AR antagonist) antagonized responses to (7)isoprenaline in both KO and FVB mice. (7)-Isoprenaline mediated relaxation of ileum was antagonized weakly by ICI118551 (100 nM...

This study was carried out in order to evaluate the changes of Nitrogen, phosphor and potassium uptake by wheat and remaining of them in soil under foliar application of Leonardite and foliar application of N and K. The experiment was conducted in Gorgan University of Agricultural Sciences and Natural Resources during 2013- 2014. The experiment was laid out a using split-plot arrangement based ...

This experiment was conducted to determine the effects of nitrogen and phosphorus fertilizers on nutritive value of safflower forage and silage by in situ and in vitro methods. The safflower forage was harvested at flowering stage, chopped to 3-5 cm particles and then ensiled in the laboratory silos for 60 days. The experimental treatments included: 1. Unfertilized forage (control), 2. Phosphor...
