Abstract
Two successful field trials were carried out during 2000/01 and 2001/02 seasons at Agricultural Experimental Station, Faculty of Agriculture, Cairo University, Giza, Egypt to study the effect of irrigation intervals and plant densities on productivity and seed quality of faba bean sown in three sowing dates (15 October, 31 October and 15 November).The experimental design used in each experiment (sowing date) was a split plot with four replications. Irrigation intervals (25, 35 or 45 days) were arranged in main plots and plant densities treatments (25, 33, 50 and 75 plants/nr') were assigned to sub plots. Results obtained could be summarized as follow:
Sowing faba bean on 15 October gave significantly increasing in straw and biological yields/faddan, seedling dry weight. However, sowing on 31 October- gave the highest values of seed yield/faddan, protein, oil, ash, phosphorus, 100-seed weight and volume, bulk density, dehulled seeds, hydration after cooking and stewing%,. Sowing 15 November produced the highest values of normal germination, tannin and fiber content in faba bean seeds.
Irrigation every 25 day intervals significantly increased fiber content, total carbohydrate and tannin content in faba bean seeds. However, Irrigation every 35 day
intervals gave the greatest seed yield/faddan, high seedling dry weight, bul� density,
hydration coefficient after cooking, total soluble solids and stewing %. Irrigation every 45
days gave the greatest values of 100-seed weight and volume, hydration coefficient after soaking, hulls % and dehulled seeds % Protein %, oil % and phosphorus .
Sowing 25 plants/m2 produced the highest bulk density and stewing %. However, sowing 33 plants/m2 gave the highest values of seed, straw and biological yields/faddan, total carbohydrates, tannin , ash, 100-seed weight and volume, hydration after cooking. Sowing 'SO plants/m2 significantly increased hydration coefficient after soaking, dehulled seeds % and
total soluble solids. normal germination. The dense population (75 plants/m2
scored the
highest values of normal germination, fiber % and phosphorus level in seeds.
