Improving Phosphorus Use Effeciency and Its Effect on the Productivity of Some Crops

Abstract

A field experiment was carried out in two successive seasons at El-Ismailia Agric. Res. Station, ARC, in El -Ismailia Governorate, Egypt, to study the efficiency use of two different sources of P fertilizer i.e. superphosphate (SP) versus rock phosphate (RP),both of them were used with three levels (0, 22 and 30 Kg P2O5 fed -

Effects of Mono-Ammonium Phosphate and K-Humate Applications on Grain Yield and Phosphorus Uptake Efficiency of Bread Wheat Crop (Triticum aestivum L.)

“…Similarly, Papadopoulos [10] found that the AR of barley plants decreased significantly when phosphorus doses applications were increasing in mono-ammonium phosphate (MAP), diammonium phosphate (DAP) and triple superphosphate (TSP) forms. Under field conditions, in contrast to our results, El-Etr et al [13] found that AR of corn and sesame plants were increasing when the phosphorus application increased. Also, K-Humate (K-H 12 ) application according to control (K-H 0 ) while AR of Bayraktar 2000 variety increased significantly by 12% (21.69%) at P 17.5 applications, it was decreased significantly by 40% (9.75%) at P 35 application and 12% (15.72%) as K-Humate average ( Table 3).…”

“…In addition to, as phosphorus average when phosphorus doses were increasing (P 17.5 = 17.5 and P 35 = 35 kg P ha -1 ) according to control (P 0 , 3.19 ton ha -1 ), the grain yield 11% and 12% respectively were increased significantly and when K-Humate did not apply depending on control (P 0 , 3.17 ton ha -1 ), %10 and %18 respectively were increasing significantly too (Table 1). A similar result, on bread wheat by [17][18][19], on durum wheat by Peker [20], on barley by Valizadeh et al [21], on corn by Saeed et al [22] and on corn and sesame by El-Etr et al [13] were stated that the plant grain yield increased significantly by increasing phosphorus application to the soil. The effect of the K-Humate application on the grain yield has changed according to the amount of phosphorus application.…”

“…So, while the K-Humate (K-H 12 ) applied to the soil depend to control (K-H 0 ), the grain yield was increased significantly by a 1.3% according to the P 0 application, and by a 2.2% according to the P 17.5 application, but when the P 35 applied, grain yield was decreased significantly by an 8.8% (Table 1). Under P 0 and P 17.5 applications as a similar result but as an opposite result in P 35 application some researchers, El-Etr et al [13] corn and sesame, Mtua et al [23] dry common bean, on corn plant by Daur and Bakhashwain [24], Khaneghah et al [25] and Erdal et al [26] stated that the plant grain yield was increased significantly with the application of K-Humate according to control in basic reaction soils. Kumar et al [27] reported that the increase in the ) applications depend on control (P 0 , 0.215) in 8% and 4% respectively.…”

“…Özaktan [12] referred to under field conditions in neutral (pH = 7.1) soil, humic acid (HUMANICA) applications according to the control while agronomic phosphorus uptake efficiency (AE) and apparent recovery phosphorus use efficiency (AR, %) of common bean (Phaseolus vulgaris L.) plant were increasing, physiological phosphorus uptake efficiency (PE) of common bean (Phaseolus vulgaris L.) plant decreased. Under field conditions, one trail indicated that increasing of different amounts of phosphorus and K-Humate applications to basic reaction soil, showed that the grain yield and apparent recovery phosphorus use efficiency (AR, %) of maize and sesame plants were increased [13].…”
