In order to study the effect of chemical and biological fertilizers on silage corn under different plant densities, a split plot experiment was carried out in a randomized completely block design with three replicates in south western Iran. The main plot included nitrogen fertilizer treatment at three levels (N1: with out chemical and organic fertilizers, N2: 75% chemical fertilizer + 100% orga...

Synthetic chemistry and plant biology intersect in myriad ways. To date, however, the overlap of research methods between these two fields is limited. Outside of the agrochemical industry, most synthetic chemists simply view plants as sources of diverse and structurally complex organic molecules (i.e. natural products), frequently with exquisite biological activities. Little knowledge of plant ...

abstractbackground and objectives: satureja khuzestanica is valuable and endemic medicinal specie that growing widely in southwest parts of iran. this specie is rich of phenolic compound carvacrol, therefore have considerable biological activities. satureja khuzestanica is a new medicinal plant in iran, and little research has been done on. thus, the present study with the aim of evaluating the...

considering the importance of medicinal plants growth and biological application of fertilizers with sustainable agricultural production in order to eliminate or reduce chemical input to achieve desirable and sustainable quality, an experimental research was  conducted based on a randomized complete block design with two factors of chemical nitrogen (46% urea nitrogen) at  two levels (zero, 25 ...

Macaranga myrmecophytes (ant-plants) are generally well protected from herbivore attacks by their symbiotic ants (plant-ants). However, larvae of Arhopala (Lepidoptera: Lycaenidae) species survive and develop on specific Macaranga ant-plant species without being attacked by the plant-ants of their host species. We hypothesized that Arhopala larvae chemically mimic or camouflage themselves with ...

Insect herbivores contend with various plant traits that are presumed to function as feeding deterrents. Paradoxically, some specialist insect herbivores might beneWt from some of these plant traits, for example by sequestering plant chemical defenses that herbivores then use as their own defense against natural enemies. Larvae of the butterXy species Battus philenor (L.) (Papilionidae) sequest...

in order to study the effects of integrative applications of chemical fertilizers and biofertilizers on grain yield and oil of borago officinalis under water deficit stress, a field experiment was conducted at kermanshah, iran, in 2011. experiment was arranged as split plot under a randomized complete block design with 3 replications. water deficit stress with four levels was applied as the mai...

kelussia odoratissima mozaff. is an iranian endangered endemic edible plant with enormous use in the middle region of iran as food and spice especially yogurt seasoning, and as medicinal herb as anti-inflammatory and cardiovascular purposes. although antioxidant, anti-inflammatory and hypolipidemic effects of this plant have so far been studied, but chemical analyses of the non volatile constit...

in order to investigate the effect of organic and chemical fertilizers on growth characteristics of marjoram, a factorial experiment was conducted based on randomized complete block design with three replications at the agricultural research station, ferdowsi university of mashhad during 2012-2013 growing season. treatments were comprised of four urea levels (0, 21.7, 108.7 and 195.7 kg.ha-1) a...
