The Effect of the Quantity and Quality of Water on the Weight and Rates of Germination of OryzaSativa of the Family Gramineae in Iraq

Abstract

The experiment was conducted in Kufa district Najaf Province fromthe periodo (1/8/2015)to(13/8/2015) to find out the effect of water amount used for seeds irrigation (50,100,150 ml water / kg soil).And water quality(drang water 2900 Micro Siemens \ cm, river water 673 EC) Micro Siemens \ cm), tap water (EC 627 Micro Siemens \ cm) on seed weight and germination percentage Oryzasativa L.by taking Sample between other day from sowing till 13thday Results showed that there were an increase in seed weightwith irrigation with 150 ml/kg soil and tap water it reach the percentage of %311.1 ،173.3% ,respectively.Germination percentage also increase to reach 100% at the 6th dayfrom sowing with treatment 1 Mean while germination percentage of 100%was appear in the8th day but with aquality of water of 100 ml/kg Soil .This situation continued until the end of experiment after13 th day of Sowing Nevertheless ,Seed weight was different at the end of the experiment at the above two treatment whilel, germination Percentage 100% after passing 13 day for tap Water treatment.
