Abstract |
Tow lysimeter experiments were carried out during the two successive seasons of 2001/2002 and 2002/2003 at El-Gemmeiza Agriculture Research Station; in lysimeters (2m in length, 1m in width and 2m in depth) cultivated by broad bean seeds variety Giza 3. The experiment was designed to study the effect of irrigation regime i. e. irrigation after 30 or 60% available soil moisture depletion (A.S.M.D) and potassium fertilization levels i. e. 0, 12 and 24 Kg K2O/fed on some water relation, yield and yield components of broad bean and potassium phases of different soils (clay, loamy, calcareous and sandy) under the study. Split plot design was used.
The obtained results could be summarized as follows:-
• The highest yields of seed, straw (Kg/fed.) and 100-seed weight (g) were obtained when 60% available soil moisture depletion (A. S. M. D) was used with application of 24 Kg K2O/fed.
• Dry matter (%) of both seed and straw were increased with decreasing (A.S.M.D.) and with increasing with potassium levels addition.
• Total irrigation water applied increased by increasing (A.S.M.D.) for all soils under investigation. Sandy soil recorded the greatest amount of total irrigation water applied, while the lowest one was obtained from clay soil.
• The seasonal consumptive use increased by decreasing (A.S.M.D.) or increasing potassium application levels. The highest values of consumptive use (Cu) were recorded by 30% (A.S.M.D.) with 24 Kg K2O/fed for all studied soils.
• Increasing (A.S.M.D.) led to an increase in water use efficiency (W.U.E.) for all soils.
• Increasing potassium fertilizer levels up to 24 KgK2O/fed increased (W.U.E.) for all soils.
• Application of 24 kg k2O/fed with 60% (A.S.M.D.) reflects the highest values of (W.U.E.) for all soils. The highest values of (W.U.E.) were recorded by clay and loamy soils compared with the two other soils.
• Soluble and exchangeable potassium soils increased by decreasing (A.S.M.D.) and increasing potassium application rate, while fixed and total potassium take the opposite rate where they increased by increasing (A.S.M.D.) and increasing potassium application rate.
• Potassium concentration and uptake in both seed and straw of broad bean increased by either decreasing (A.S.M.D.) or increasing potassium rate
