Description A pot culture experiment entitled, " Studies on fertilizer use economy
for maize crop through vermicompost" was conducted at College of
Agriculture, Pune-5 in randomised block design during the year 2002-2003 in
monsoon season. The pot culture experiment comprising 20, 40, 60, 80 and
100 per cent recommended dose of N in combination with vermicompost @ 20, 15, 10, 05 and 0 t ha"1 alongwith one control without inorganic fertilizers
and vermicompost.
Firstly vermicompost was prepared from soybean waste to
study the chemical changes during the process of vermicomposting.
Vermicompost prepared was neutral in reaction . Marked decrease was
recorded in the C/N ratio of soybean waste. The N, P and K content of
substrate also increased spectacularly during the process of vermicomposting.
Results of pot culture study revealed that vermicompost
application with reduced dose of recommended fertilizers had a positive effect
on uptake of nutrients by maize crop at tasseling as well as harvesting stage.
The dry matter yield of crop was higher in treatments receiving vermicompost
application in conjunction with inorganic fertilizers than control and
application through inorganic fertilizers only. Treatment with 60 percent recommended dose of nitrogen fertilizers and vermicompost @ 10 t ha"1
increased the uptake of N, P and K nutrients significantly. Micronutrient
uptake also increased in the similar treatment than all other treatments under
studies.
Soil analysis after the harvest of crop showed the effect of
vermicompost application on the soil fertility. Soil analysis results showed
that ' the organic carbon content of soil increased significantly by vermicompost application. When vermicompost applied @ 10 t ha'1 with 60
percent recommended dose of nitrogen through chemical fertilizers, the
available nitrogen, phosphorus and potassium content of soil increased significantly. DTPA extractable micronutrient (Fe, Mn, Zn and Cu)
concentration was higher in the same treatment than other treatments.
The vermicomposting process increased utility of waste material
by enriching initial substrate. Nutrient value of the waste could be improved
by the process of vermicomposting. Integrated use of inorganic fertilizers with
vermicompost was found beneficial. Reduced recommended dose of fertilizers
alongwith vermicompost application recorded promising results than farmer's
practice and use of chemical fertilizers only. Vermicompost application not
only increased uptake of nutrients by the crop but also maintained the soil
fertility for macro and micronutrients.
