A two-year field study was conducted in winter seasons to investigate the effect of three tillage systems (one, reduced & conventional), three fertilization regimes (P, NP & NPK) and three plant population densities (formed by different hill spacing of 15, 20 & 25 cm among hills) on growth and productivity of faba bean cultivar, Giza 843. Response of number of pods and seed yield per plant, 100-seed weight and seed yield per faddan to tillage systems were significant, where conventional tillage gave higher values for these traits compared to no-and reduced tillage practices. Seed yield per plant, 100-seed weight and seed yield per faddan responded significantly to the fertilization regimes, where NP and NPK produced the highest seed yield per faddan, compared to P fertilization only. Number of pods and seed yield per plant and 100-seed weight significantly increased with increasing the spacing among hills, whereas the intermediate hill spacing of 20 cm produced t
