one of the important aspects of the medicinal plants production is using less chemical inputs. it could be effective for increasing of production and environmental purposes. in order to investigate the effects of application time of integrated chemical fertilizer with cattle manure on growth, yield and yield components of black cumin (nigella sativa l.), an experiment was conducted based on a r...

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...

Nitrogen is a crucial nutrient affecting plant growth and development and its addition to the soil (as chemical or organic form) influences plant growth characteristics. One experiment was conducted as a factorial based on RCBD with two Chrysanthemum cultivars (‘Fred’ and ‘Angel’( and two N-fertilizer sources [Urea (750 and 1500 g/ha and Nitroxin 7.5 and 15 L/ha] used as fertigation method besi...

this research was carried out for the purpose of urea fertilizer, organic matter and pgpr bacteria effects on yield and some growth indices on winter wheat (triticum aestivum c.v alvand). this research was carried out with factorial experiment on completely randomized design with 4 replication in greenhouse. treatments included bacteria 4 levels, without bacteri, a. brasilense, a. chroococum, i...

Background: Since alkaloids are nitrogenous compounds, the availability of nitrogen (N) is expected to play an important role in the biosynthesis and accumulation of alkaloids in plants. Nitrogen has been found to increase the content of alkaloids in some of the medicinal plants. Objective: The aim of this study was to compare the effects of nitrogen bio-fertilizers, conventional nitrogen fe...

in order to evaluate the effect of different sources and rates of nitrogen the growth and biomass production of purslane, a randomized complete block design was conducted with three replications at the agricultural research farm of shahrekord university in 2012. fertilization treatments were consisted of control (no n amendment), 30 and 90 kg n ha-1in the form of urea fertilizer, 30 and 90 kg n...

BACKGROUND: Fertilizer management plays an important role for obtaining satisfactory yields and to increase crop productivity. Nutrient management may be achieved by the involvement of organic sources, bio fertilizers, and micro-nutrients. OBJECTIVES: Assessment effect of chemical and biological fertilizer on seed yield, its components and plant height of...
