Abstract
Under field conditions, wheat response to organic amendments and B. megatherium inoculation as well as different rates of natural rock P fertilizer (NRP) was traced. Grain yield of wheat was higher with 100 kg P ha-1 than rate 50 kg P ha-1 while both of them surpassed the un-fertilized control. In case of inoculated plants, grain yield was significantly higher with quail feces additives than animal manure and peanut residues. B. megatherium induced slight increases in N uptake comparing to the un-inoculated plants. Peanut residues, but slightly, resulted in N uptake values higher than either quail feces or animal manure. Increasing rock-P levels increased N uptake over the unfertilized or those received 50 kg ha-1 treatments. Added quail feces had increased P uptake over those resulted from peanut residues and animal manure. Quail feces resulted in relative increase of P uptake by about 5% and 15%; 16% and 19%; 17% and 4% over peanut and animal manure for P0, P50 and P100, respectively. Inoculation with B. megatherium had, to some extent, enhanced K uptake by grains comparable to the un-inoculated one when plants treated with peanut residues. Nitrogen portion derived from (Ndforg) peanut straw and quail feces to inoculated plants was relatively increased, on mean average basis, by about 19% and 16%, respectively over the un-inoculated plants. Efficient use of N derived from peanut straw and quail feces (Org-NUE %) as well as urea-NUE% by inoculated plants was slightly increased under all rock-P levels over those of the un-inoculated plants.
