| Abstract | ||||
| This study was carried out under greenhouse conditions on soil taken from Kalubiya, Governorate, Egypt to study the response of Faba bean plant for bio-fertilizer and with natural sources of potassium fertilization i.e., compost rich in K content (CK) and K-feldspar (K-bearing mineral, KAlSi3O8) (FK) compare with Potassium sulfate, K2SO4 (MK). They were added in a solo or in a mixture forms at rates of half (1/2 KD), three–quarter (3/4 KD) and full (KD) of the recommended dose (R.D) of potassium (KD = 24 Kg K2O / fed.). Faba bean (Vicia faba.L , cv. Giza 843 variety) were inoculated with K-dissolved bacteria Bacillus circulans, (KDB). Yield and contents of (N), ( P), (K), (Fe), (Mn) and (Zn) were studied. The results revealed that inoculation with (KDB) gave the highest seed and straw yields. Moreover, N, P, K, Mn and Zn contents increased as compared with non- inoculation conditions. K-rates significant increased straw, seeds and nutrient contents in compare with non – fertilizer treatment (control). As for the effects of different types of K-sources on seed and straw yields as well as their nutrients content, (MK) was the best treatment followed with (FK) treatment, when both added in a solo form. With respect to the dual mixture (MK+FK) followed with (MK+CK) gave the best effects. While, (FK+CK) and the triple mixture of (MK+CK+ FK) gave pronounced response on the yield of seed and nutrient's contents. | ||||
