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...

The treatments in bio-systems correspond to respective repairs known in reliability. Some treatments may make the biological objects younger; others may make them older, or not deteriorate their current age. Such kind of “maintenance” has some analogous failure/repair models in reliability. We use it to incorporate some results of reliability and bio modeling for the quantitative studies of the...

rose flower (rosa hybrida) is appreciated for its beauty, fragrance and long period of flowering. to study the response of cut rose flower to bio-fertilizers, a factorial experiment was performed, with completely randomized design and four replications, in hydroponic greenhouse of alandasht, astane ghods garden, mashhad, iran, during 2009-2010. the first factor was six cultivars of rose flower ...

in order to determine the effects of applied phosphate bio-fertilizer on yield and morphological traits of wheat, a research was conducted in sari agricultural sciences and natural resources university during 2008-2010. a factorial experiment was performed based on randomized complete block design with four replications. the first factor consists of two levels of phosphate bio-fertilizer (0 and...

Effects of bio-nitrogen fertilizer (bio-N), as a partial alternative to mineral-nitrogen fertilizer (mineral-N), on growth, yield and yield quality of broccoli plants were investigated. Bio-N was applied at 1, 2 or 3 doses in combination with 65% of the recommended dose of mineral-N (bio-N1, bio-N2 or bio-N3 + 2⁄3mineral-N). However, 100% of the recommended dose of mineralN was applied as a con...

The use of biostimulants has become a common practice in agriculture. However, there is little peer-reviewed research on this topic. In this study we tested, under controlled and replicated conditions, the effect of one biostimulant derived from seaweed extraction (Bio-1) and another biostimulant derived from microbial fermentation (Bio-2). This experiment utilized 2-years-old almond plants ove...

The experiment was conducted under in vitro and field conditions to observe the effect of bio-agents, botanical and fungicides against Alternaria triticina. Eight treatments were taken up with three replications and data collected was analyzed using CRD. Maximum inhibition per cent mycelia growth was observed in Propiconazole (89.72%), Hexaconazole (88.44%), Vitavax (87.70%), followed by Tricho...
