Effect of Irrigation with Drainage water at Sorghum growth stages on salts accumulation and growth, yield of crop

Abstract

This experiment was conducted at farm in garma city during atum season 2004 in silty loam texture, classified as Typic torrifluvent to study the effect of Irrigation with Drainage water average 3.48 ds.m-1 at (Germenation stage T2, seedling stage T3, Tillering stage T4 flowerd and yield formation T5and at whole growth period of yield T6) and in comparison with Irrigation with river water 1.25 ds.m-1 was used as a control T1 on salts accumulation and growth and production of Sorghum (variety Ankath). Result showed that the River water was suitable water and the drainage water was non suitable for Irrigation, also noticed that the Irrigation with drainage water at whole period of growth and Irrigated at flower and yield formation caused significantly increaseing in salt accumulation and SAR [ 8.17 ds.m-1, 5.03 (m mol. L-1)1/2 ] [ 5.93 ds.m-1, 4.36 (m mol. L-1)1/2 ] on soil respectively compared with Irrigation river water and Irrigation with saline Drainage water at stages germenation, seedling, Tillering, [4.33 ds.m-1, 2.64 (m mol. L)1/2 ], [3.77 ds.m-1, 3.57 (m mol. L-1)1/2 ] [3.13 ds.m-1, 3.45 (m mol. L-1)1/2] [3.39 ds.m-1, 3.38 (m mol. L-1)1/2], also the Irrigation with River water and Saline Drainage water at stages germenation, Seedling, Tillering caused Leaching of salts from surface layer and getting accumulation salts at Irrigated with saline Drainage water at whole period of growth and flowering and yield formation compared with soil salinity soil before farming (4.9 ds.m-1). The Irrigated with saline Drainage water at whole period of growth, at flowering and yield formation and Tillering caused significantly decreased on weight of seed, dry weight and plant high (55.93 gm, 229.2 gm, 113.83 cm), (67.60 gm, 308.1 gm, 129.22 cm), (73.87 gm, 306.2 gm, 132.55 cm) respectively compared with Irrigated River water (171.9 gm, 421.3 gm, 141.52 cm).
