Effect of maize based Conservation Agriculture Production Systems (CAPS) under tribal farming situations of Odisha in India
A summary of 2011-2012 trial plot results in terms of yield and profitability. Tillage and intercropping had no significant effect on maize yield (4890 kg ha 1) in the first year. The highest maize yield was recorded in maize+cowpea under minimum tillage (5610 kg ha 1). Economic return in case of intercropping was 38% higher than that of sole cropping, across both the tillage types. Though there was no significant effect of CAPS on soil properties in the first experimental year, trends were positive for soil pH, bulk density, and soil carbon.
