Efficiency of different incubating material for phosphate rich organic manure in wheat (Triticum aestivum)

A field experiment was conducted at Centre for Research on Integrated Farming Systems, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar during 2018–19 to 2020–21 to study the efficiency of differ- ent incubating material for phosphate rich organic manure (PROM) in wheat. A total of fourteen treatments such as T1 : Control, T2 : DAP @ 60 kg P2 O5 /ha, T3 : Rock phosphate @ 40 kg P2 O5 /ha incubated with vermicompost, T4 : Rock phosphate @ 60 kg P2 O5 /ha incubated with vermicompost, T5 : Rock phosphate @ 40 kg P2 O5 /ha incubated with FYM, T6 : Rock phosphate @ 60 kg P2 O5 /ha incubated with FYM, T7 : Rock phosphate @ 40 kg P2 O5 /ha incu- bated with compost, T8 : Rock phosphate @ 60 kg P2 O5 /ha incubated with compost, T9 : Rock phosphate @ 40 kg P2 O5/ha incubated with vegetable waste, T10 : Rock phosphate @ 60 kg P2 O5 /ha incubated with vegetable waste, T11 : Rock phosphate @ 40 kg P2 O5 /ha incubated with green algae, T12 : Rock phosphate @ 60 kg P2 O5 /ha incu- bated with green algae, T13 : Rock phosphate @ 40 kg P2 O5 /ha incubated with cow urine and T14 : Rock phosphate @ 60 kg P2 O5 /ha incubated with cow urine were evaluated based on growth parameters, yield attributes and yield. The pooled result of three years experiment indicated that phosphorus source of DAP in wheat (60 kg P2 O5 /ha) can be replaced with Udaipur rock phosphate (31% P2O5 ) @ 198 kg/ha incubated for 30 days with FYM or vermicompost or compost or vegetable waste (each of 593 kg) or cow urine (593 L) in the ratio of 1:3 ratio as basal for obtaining higher yield and net returns.
