review and goals: the ajowan(carum copticum) is a medicinal plants from apiaceae family that seeds contains 2-4% of volatile oil. 9-17 of chemical composition of ajowan essential oil have been reported(2), it have antibacterial and antioxidant activity of it caused to preserve the food materials(1). the application of chemical fertilizer leads to environmental pollution and ecological disaster ...

Producers in semi-arid and highland regions have difficulty increasing diversity crop rotations due to unfavorable conditions imposed by cool temperatures, inadequate rainfall, shorter growing periods. In such conditions, some cultural practices that increase productivity as fertilization appear a promising alternative. Fertilization the form of fertilizer substantial influence on sunflower (He...

A greenhouse trial assessed the effects of biochar and vermicompost as partial substitutes conventional growing media on leafy vegetables’ yields changes NH 4 + -N NO 3 − in medium leachates. Six mixtures [(a) coir, (b) coir biochar, (c) vermicompost, (d) peat, (e) peat +vermicompost, (f) biochar] combined with three nitrogen (N) rates [0% (0 g N·pot −1 ), 50% (0.5 100% (1.0 ) commercial recomm...

Recycling organic waste is most important for preserving natural resources. The research objective was to quantify the effect of application vermicompost and leachate on yield quality strawberries compare it with a standard fertilization program mineral fertilizers during 3-year production cycle. Five treatments were studied: control—without fertilizer (Ø); (V); + foliar (VL); through fertigati...

In this study effect of application of food waste vermicomposts to soil on antioxidant compounds, fruit yield and quality of sweet pepper (Capsicum annum L.) were investigated in field condition. Four vermicompost levels (0, 5, 10 and 15 t/ha) were applied to soil based on a randomized complete block design with three replications. The results showed that the highest (21.87 kg m2)and lowest (14...

Vermicomposts processed commercially from food wastes and paper wastes were applied, to 4.5 m(2) field plots, under high plastic hoop tunnels, at rates of 5 or 10 tha(-1) to evaluate their effects on the growth and yields of strawberries (Fragaria ananasa) var. 'Chandler'. The vermicomposts were incorporated into the top 10 cm of soil and supplemented, based on chemical analyses, with amounts o...

In the present work bagasse (B) i.e waste of the sugar industry, was fed to Eisenia fetida with cattle dung (CD) support as feed material at various ratios (waste: CD) of 0:100 (B0), 25:75 (B25), 50:50 (B50), 75:25 (B75) and 100:0 (B100) on dry weight basis. Co-composting with cattle dung helped to improve their acceptability for E. fetida and also improved physico-chemical characteristics. Bes...

organic compost can reduce various plant stresses, because of its porous structure, high water storage capacity, and existence of some substances resembling hormones and plant growth regulators. this study was performed to investigate interactions of different levels of vermicompost extract and salinity stress on morphological characteristics of bean seedlings. the experiment was conducted in c...

iron deficiency or lime induced chlorosis is a common problem in calcareous soils. application of mineral iron fertilizer in these soils is not usually fully effective in curing iron deficiency as compared to organic chelates. cow manure and iron refuse (oxides), a by-product of iron melting factories were mixed in different properties of: 0, 5, 10, and 20 % v/v to make mixtures which of after ...
