Effect of seed bed preparation system and fertilizer management on soil water storage and barley production yield [electronic resource].

Includes references.

The experiments were carried out to study the effect of seed bed preparation system and fertilizer management on soil physical properties, soil water storage, water distribution efficiency and barley yield. The experimental soil was classified as a heavy clay compacted and barley v. Giza 123 was planted, surface irrigation system was used. Three seed bed preparation systems were used: the first system was chisel plough (twice) and land leveler, the second was chisel plough (one pass) followed by rotary plough and land leveler and the third was no tillage with land leveler as a control. Three fertilizer management were conducted using mineral fertilizer 100% N mineral, organic fertilizer 100% N organic and mixed 50% N mineral and 50% N organic fertilizers. The obtained results reveal to the following: seed bed preparation systems using chisel plough one pass followed by rotary plough and land leveler and organic fertilization management by manure fertilizing machine (treatment, E) is considered the proper system for soil water storage and for producing barley crop. Whereas the maximum reduction in bulk density of 15.97 %, maximum increase in soil porosity of 53.2 %, maximum increasing in accumulative infiltration rate were 6.28 cm, maximum value in soil water storage and water distribution efficiency of 392.45 m3.fed.-1 and 57.35 %, respectively. Finally, the maximum barley yield of 1.86 ton/fed with minimum criterion cost of 58.94 L.E/ton
