Efficiency of P sources under different soil types in rice-rice system


Farming Systems 8(1-2): 30-35
Efficiency of P sources under different soil types in rice-rice system
In field trials in 1986-90 on an Entisol (pH 5.1) at Jorhat (Assam, summer and kharif seasons), an Entisol (pH 6.4) at Chiplima and a Ultisol (pH 5.6) at Bhubaneswar (Orissa, kharif and rabi , in 1983-85 on an Alfisol (pH 7.4) at Bhavanisagar (Tamil Nadu, kharif and rabi) and in 1984-85 and 1986-87 an a Vertisol (pH 8.0) at Siruguppa (Karnataka, kharif and rabi) rice was grown in both seasons and each crop given 0-90 kg P/ha as various combinations of single superphosphate (SSP), rock phosphate (RP), SSP + RP, ammonium polyphosphate, diammonium phosphate, phosphal (calcium aluminium phosphate), nitrophosphate or urea phosphal. Grain yield increased with up to 30 kg P/ha in both seasons at Jorhat and Siruguppa, with up to 60 kg in the kharif and 30 kg in the rabi in Chiplima, generally with up to 60 kg in Bhubaneswar and with up to 60 kg in kharif and 90 kg in rabi at Bhavanisagar. It was recommended that for acidic soils, RP or SSP+RP should replace the use of SSP alone in a rice-rice system. In alkaline soils, phosphal gave promising results, as well as DAP and nitrophosphate.
