Can anyone have the information regarding the average nutritional status of this cocopeat and vermicompost? I want to know whether the cocopeat has the capacity to stand alone for a crop?
Studies on chemical properties of Cocopeat with different ...

PDFApr 30, 2019 - N, P, K, Ca, Mg, Fe, Mn, Zn, Cu of six different media comprising of (w/w) ... found in Cocopeat+ Vermicompost + Biocompost (5:1:1) (T5) followed by ... to low, medium and high level of soluble salts present in the medium
1.Vermicompost contains 1.25 :1.14 : 1.19 percent NPK, respectively.
2. In Cocopeat 0.41:0.81:1.32 % NPK Respectively.
Cocopeat by itself does not have content nor the availability to optimize growing media.
Studies from The Ohio State University show grower results using a peat based media with full nutrient allowance can be advanced significantly by inclusion of 10 to 20% vermi compost which in the cause of tomato can increase the yield up to over over 50% superior to fertilizer supplemented media without organic amendment from vermicompost.
Vermiccompost is balanced and complete nutrition and is highlighted by a growth regulation action which is from humic components in the compost.
My recommendation for media would be to include some 20% silicate sand and 20% vermicompost to a cocopeat product and you will be highly successful.
Search Atiyeh et al Tomato vermicompost using a Google Scholar search and you can assess the exact results.

Only raw cocopeat is not sufficient to supply plant nutrients due to its very high C/N ratio. So, bio-degraded cocopeat should be used having lower C/N ratio, higher CEC and humic acid than the raw cocopeat. Ratio of Cocopeat (70%) + Vermiculite (20%) + Perlite (10%) is also popular than using cocopeat alone.
Ravindra M. Muchhadiya Manjanagouda S Sannagoudar then which factor of these both media affects the plant growth? like if cocopeat is rich in k, then is it benefits the plant or not? same for vermicompost.
In terms for Ravindra M. Muchhadya and Karun Katoch.
Cost is a very important consideration in media this is one reason I like sand as an ingrediente perlite has excellent properties but can be somewhat expensive and might be used as the lowest benefiicial dose in that regard. In relation to vermiculite it is generally much more price competitive but check that the source has no abestos issues wihich if found in some mines.
Vermicompost provides complete organic nutrition it is balance for NPK has all secondaries and micronutriients need for plant nutrition. Its principal issue would be cost. In that regard and for longer term nutrition I have good experience and would recommend using 4 to 1 leaf compost to vermicompost and then using this product at 10 to 20% of the blend.
Check your analysis of your components and blends and your soils and you can match up a blend ideal for your particular need.
I dont think , cocopit alone can support the plant growth , unless fortified with some nutrients. ...
The concern with coir pith (cocopeat) is C:N ratio. One can build Nutrients in it through enrichment. Brining down the ratio is primary objective
Cocopeat has a carbon-nitrogen (C/N) ratio of 104:1. Cocopeat can store and release nutrients to plants for long periods of time. pH value of Cocopeat ranges between 5.2 and 6.8 which is neutral to slightly acidic.
Anoop rightly mentioned that cocopeat alone can not support. There is need to fortify media.
Our experiences with cocopit says it has pH upto 8 , unless acid washed.Good point Dr Malhotra , microbial fortification could be one effective way to add value to nutrient supply....
If C: N ratio of a given substrate is high , that substrate can't release nutrients, unless ratio is brought down....to maturity level to serve as growth substrate...
It will be interesting to know , how much time , it takes fro vemicompost to release its nutrients into the assimilable forms....regardless of crops annd soils...
1.Vermicompost contains 1.25 %, 1.14 % , 1.19 % NPK respectively.
2. In Cocopeat 0.41%,0.81%,1.32 % NPK Respectively.
Rightly said, cocopit not only has less concentration of nutrients compared to vermicompost , the rate of mineralization is also comparatively lower ...with time..
Vermicompost - 1.25 :1.14 : 1.19 % NPK
Cocopeat - 0.41:0.81:1.32 % NPK
The relative contents of N, P and K in vermicompost vary depending upon a number of factors. Since vermicompost is considered an improved compost, as a thumb rule, the content of N, P and K must be at least 3 times of those in traditional compost. In general we have observed 1.5 to 1.8% N and 1.6 to 2.0% K in harvested vermicompost. The P content is observed between 0.8 and 1.1% in the vermicompost.
