| Abstract | ||||
| A field experiment was carried out in the in winter season of 2015/2016 at sandy soil in El-Sadat city, El Minufia Governorate, 30.3594° N, 30.5327° E, Egypt to evaluate the effect of phosphorus fertilization and potassium humate on the growth and yields of faba bean as well as its content of N, P and K. The experiment factors were phosphorus application at three different levels (0, 10, 15 and 30 P2O5 kg kg Fed-1) and potassium humate at rate of 0, 5 and 10 kg fed-1. Also, the phosphorus use efficiency evaluated. The obtained results could be summarized as follows: Growth and yield parameters (plant height, No. of branches, No. of pods plant No. of seed pods) were significantly increased by increasing by increasing rates of added P potassium humate individually and in combination, where the highest values were resulted from their combined treatments especially at high application rates. The combination between phosphorus at 30 kg P2O5 fed-1and potassium humate at rate of 10 kg fed-1 recorded the highest growth and production as well as minerals composition (N, P and K) content compared to the other treatments. On the other hand, potassium humate at high level combined with super phosphate recorded increased in the availability of nitrogen, phosphors and potassium. Concerning, the P-efficiency the results showed that, both agronomic efficiency and apparent recovery efficiency were recorded by the highest values when compared the P fertilizer alone. | ||||
