in this research, the effect of using vermicompost on growth rate, fertility and characteristics oftomatoes has been studied. four vermicompost: soil mixture were supplied with ratios of 1:1, 1:2, 1:3, and 1:4 and also four different beds were provided. total of 24 small globe tomato plants were tested and in each bed combination, six tomato plants were embedded. rate of growth and yielding of ...

In order to investigate the effect of vermicompost and Nano Iron on yield and yield components of maize, a farm experiment was done in a factorial based on completely randomized blocks design with three repetitions in Damavand in 2013. The first factor was vermicompost in two levels included no applying and applying (vermicompost 1kg.m-2) and the second factor was Nano iron fertilizer with four...

The comparative effect of dual inoculation of native N fixer (Rhizobium) and AM fungi consortia with different organic fertilizers (vermicompost and farm yard manure) on fodder production and quality of two leguminous tree species (Leucaena leucocephala (Lam) de. Wit. and Sesbania sesban (L.) Merr.) in silvopastoral system and their impact on the fodder production of un-inoculated Panicum maxim...

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...

Hemp, Cannabis sativa is certainly a mul­tifunctional as well niche crop, due to great po­ten­tial for innovative use of its different products. Aspects hemp mineral nutrition are very important in the cultivation these plants, particular make cul­ti­vation environmentally friendly by replacing synthetic fertilizers with organic ones. Among fertilizers, vermicompost has gained attention within ...

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...
