Abstract:
Pod yield was significantly superior in POP + 50 per cent RDN through poultry manure (2272 kg ha
-1) followed by POP + 50 per cent RDN through vermicompost (2162 kg ha
-1) and POP + 50 per cent RDN through goat manure (2018 kg ha
-1). Higher uptake of calcium resulted in POP + 50 per cent RDN through poultry manure followed by POP + 50 per cent RDN through vermicompost (32.50 and 30.95 kg ha
-1, respectively). The highest total uptake of magnesium (14.92 kg ha
-1) was recorded in POP +50 per cent RDN through goat manure, followed by POP + 50 per cent RDN through vermicompost (12.98 kg ha
-1). Significantly higher sulphur uptake (15.17 kg ha
-1) resulted in POP + 50 per cent RDN through poultry manure, followed by POP + 50 per cent RDN through vermicompost (13.60 kg ha
-1). Higher bacteria, fungi and actinomycetes population (37.27 cfu x 10
5,
41.92 cfu x 10
3 and 13.73 cfu x 10
4 g
-1 of soil, respectively) were found by the application of recommended dose of nutrients (POP) + 50 per cent RDN through vermicompost
