Abstract
Two field experiments were performed at the Experimental Farm at Ismailia Agricultural Research Station, Egypt ARC during two growing winter seasons 2020/2021 and 2021/2022 to study the integrated effect of inorganic K- fertilizer (KS) and natural feldspar (KF) in combination with silicate dissolving bacteria (SDB) as bio-fertilizer on growth, yield and nutrient NPK uptake for canola plant (Brassica napus L. serw 4). The results indicated that with all growth studied characters, adding 75% KS + 25% KF application plus seed inoculation with SDB had a positive and significant increase in growth characters i.e. No. of pods/plant, No. of branch /plant, and give a relative increase in seed and straw yields 98.9 and 99.8 %, respectively compared with the 100% individual inorganic K- fertilizer. Also, the combined treatment of 75% KS + 25% KF + SDB recorded insignificant increases in oil and protein contents as well as NPK uptake in both seed and straw for the canola plant. Conclusively, the same combined treatment (75% KS + 25% KF + SDB) can be recommended to improve growth, yield and chemical composition for canola plants in sandy soil and also, the utilization of natural K- feldspar led to reducing the high cost of chemical fertilizer and minimizing the environmental pollution.
