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...

The study was conducted to investigate the effect of nitrogen application on the yield contributing characteristics, biomass yield and nutritive values of cowpea forage. Five nitrogen levels viz: 0 (T0), 15 (T1), 20 (T2), 25 (T3) and 30 (T0) kg N/ha were applied in 20 plots in a Completely Randomized Design (CRD). The result showed that the application of nitrogen fertilizer had significant (P<...

In order to evaluate the variations of some morphological traits, yield, seed yield components and essential oil yield of German Chamomile under different application levels of nitrogen (N) and biofertilizers, a split plot experiment laid out in a randomized complete blocks design with three replications in Shar-e-Ray (Gale No) region. Chemical N fertilizer application in three levels (0, 65 an...

Abstract In order to study the effect of different soil amended and biological fertilizers on accumulation nitrogen phosphorous in wheat grain some physiological morphological characteristics wheat, this experiment was performed as a split factorial arranged randomized block design with 32 treatment three replication for 2 years. The treatments included mycorrhiza inoculation main factor (witho...

introduction in agricultural ecosystems, organic fertilizers play an important role in producing sustainable agricultural production. considering this sajjadi nik et al (2011) reported that with increasing of vermicompost inoculation with nitroxin biofertilizer, capsule number per sesame plant increased, so that the most of capsule number per plant (124.7) was observed in 10 t/h vermicompost wi...

introduction phosphorus (p) is an essential element in crop nutrition, which can be growth limiting or an environmental contaminant, if present in excess. on the other hand, tillage practices have a direct effect on behavior and availability of soil p. since, application of different tillage methods lead to different patterns of soil phosphorus distribution, hence p fertilizer needs and p avail...

in recent years, in order to enhance the health of agroecosystems, concerns on ecological inputs especially to produce medicinal plants, has been increased. in order to evaluate the effects of winter cover crops on pgprs activities and soil nitrogen content in simultaneous application of organic manures and biological fertilizer in a low input production system of cucurbita pepo under minimum t...

in order to study the influence of municipal waste compost and chemical fertilizer on yield and yield components in maize (zea mays l.) an experiment was conducted at research farm of sari agricultural sciences and natural resources university during 2007. the experiment was arranged in split plots based on complete randomized block design with two factors and three replications. main plot incl...
