In this research the effects of organic and chemical fertilizers on essential oil content and composition of lemon balm were investigated. This research was conducted in completely block randomized design with 4 replications in 2019 and 2020. Treatments were organic fertilizers (from source of horse, sheep, cow, hen and vermicompost) and complete chemical fertilizer of NPK (20-20-20). The most ...
Biosludge is a by-product of secondary wastewater treatment processes. Due to its high contents of organic carbon and plant nutrients, this bioresource can be practically reused as raw feedstock for making organic fertilizers and building materials. The objective of this paper was to provide a preliminary analysis of biosludge utilization in Taiwan, including food processing sludge, wine brewer...
The hypothesis that plants supplied with organic fertilizers are better defended against insect herbivores than those supplied with synthetic fertilizers was tested over two field seasons. Organic and synthetic fertilizer treatments at two nitrogen concentrations were supplied to Brassica plants, and their effects on the abundance of herbivore species and plant chemistry were assessed. The orga...
It is necessary to use organic fertilizers and decrease chemical fertilizers consumption to reach sustainable agriculture. Thus, to study the effects of manure incorporation methods, and integrated effects of poultry manure with chemical fertilizers on the grain yield and yield components of maize, an experiment was conducted in 2004 at the Agricultural Research Farm of Lorestan Weather Departm...
introduction savory (satureja hortensis l.) is an annual herbaceous plant that belongs to the lamiaceae family. nowadays, the use of biofertilizers is increased in agriculture and their role in increasing the crops production has been demonstrated in many research works (vessey, 2003; chen, 2006; mahfouz & sharaf- eldin, 2007). one of the most important visions is sustainable production of enou...
as polysemy is encountered frequently in english as foreign language. fl learners’ ability to disambiguate polysemous verbs becomes critical to their comprehension in the target language. this thesis, accordingly, investigated how iranian efl learners achieved comprehension of english polysemous verbs by using three different types of cues: (1) elaborated context, (2) semantic frames, and (...
The aim of this experiment was that study the effect of drought stress and different chemical and organic fertilizers systems on wheat flag leaf chlorophyll. This experiment was conducted as split plot based on completely randomized block design (CRBD) with four replications during 2009-2010 at experimental fields of Ramin university. Irrigation treatments were achived in I1(irrigation droped ...
this research set out to evaluate the effect of combined biological and chemical nitrogen fertilizers on some corn hybrids. to this end an experiment was conducted as split plot on the basis of randomized complete block design with four replications. main plots were included: use of chemical and biological fertilizers in four levels: 100% chemical fertilizer, 75% chemical fertilizer + 100% bio-...
Background & Aim:Peppermint known for its healing properties is a plant from the Labiatae family. Currently, different rates of nitrogenous fertilizers are used in production of peppermint while there is no precise information available about how much of nitrogen fertilizer is the optimum rate for this plant. The main purpose of this research was to evaluate the response of pep...
