N2  - An investigation was carried out at the Instructional 
Farm, attached to the College of Agriculture, Vellayani to 
evaluate "Nutrient economy through seed coating with 
vermicompost in cowpea". The experiment was laid out in 
Completely Randomised Design with nine treatments and three 
replications. The variety used was Kanakamoni. The treatments 
include coating of seeds with Rhizobium, vermicompost and a 
combination of both and also uncoated seeds supplied with 
either farmyard manure or vermicompost as organic source. 
Biometric observations like height of plant, number 
of leaves, seedling girth and number of fruiting branches were 
not significantly influenced by any of the treatments. 
However, root characters like root length, root spread and 
number of effective nodules were found to be significantly 
influenced by the different treatments. Coating of seeds with 
vermicompost significantly influenced the grain yield of cowpea 
and also the number of pods plant-l. Coating seeds with 
vermicompost combined with the application of full inorganic 
fertilizers and farmyard manure as organic source recorded the 
highest grain yield. From the analysis of grain samples, it is 
inferred that only K and Ca content of grain was significantly 
influenced by the different treatments. 
 
	
Phosphorus solubilisation capacity of soil was not 
significantly influenced by any of the treatments. N fixing 
capacity of soil was significantly influenced by the 
vermicompost coating of seeds during 30 DAS and 45 DAS. Soil 
analysis for available nutrients revealed that the different 
treatments had significant influence on the Ca, Mg, Zn, Cu and 
Mn content in soil. 
Use of vermicompost coated seeds produced the maximum 
uptake of N, P and K at maximum flowering stage and at harvest. 
Soil application of vermicompost recorded the highest uptake of 
Ca, Mg, Cu and Mn during maximum flowering stage. Plant 
analysis for nutrient content indicated that the content of all 
the nutrients except P was significantly influenced by the 
different treatments during maximum flowering stage. Yield was 
positively and significantly correlated with the height of 
plant, root characters and availability and uptake of 
nutrients. 
In the present study, a superiority is shown by 
vermicompost inoculated plants where farmyard manure was given 
as the organic source indicating that at times of scarcity of 
vermicompost, seed treatment could serve the purpose.
