Effect of continuous and Alternative Irrigation with saline Drainage water on salt balance in soil and growth and production of Sorghum (Variety Ankath)

Abstract

This experiment was conducted at one farms of the farmers Garma during atum season 2004 in silty loam texture, classified vertic terrifluvent to study the effect of continuous Irrigation saline Drainage water 3.45 ds/m and Alternative with river water 1.25 ds/m (Irrigation twice river water followed once by drainage water T2, Irrigation once with river water followed once by drainage water T3, Irrigation once with river water followed twice by drainage water T4) irrigated with river water was used as a control. On salt balance in the soil and growth and production of Sorghum (Variety Ankath). Results showed the river water was suitable water for irrigated and drainage water was non suitable water for irrigated, and appeared at incensed number of drainage water irrigated (T4, T5) caused significantly higher in soil saline (5.9, 8.8) ds/m respectively and significantly higher in SAR 4.4, 5.4 (mmol.L-1)1/2 respectively compared with irrigated river water 4.3 ds/m, 2.1 (mmol.L-1)1/2. Caused irrigated T1, T2 decreased in soil saline and irrigated T3, T4, T5 caused accumlalion in soil saline comported with soil saline before farming 4-9 ds/m. also irrigated T1, T2, T3, T4 and T5 caused increased in SAR comported with SAR before farming 1.55 (mmol.L-1)1/2. Irrigated alternative and continuous T3, T4, T5 caused significantly decreased in plant high and dry weight compared with irrigated T1, T2, also alternative Irrigated T2 caused decrease 14.5% in production, its still during the produces use of saline water in Irrigation for economics fields and saved about 28.57% sutiable water.
