Abstract

Pot experiment was conducted at the Faculty of Agriculture / Anbar University during the Fall 2014 season as the study included two factors: the first is the irrigation water and three types: water and river water with salinity 4 dS m-1. In addition, with salinity 6 dS m-1, and the second factor is the organic extracts (Peat reeds) and three levels: 10, 20 g L-1 and it was sprayed three times. The study was conducted using three replications and randomized complete design sectors (RCBD). 2014 to study the effect of salt water and peat reeds use in some recipes the soil and the growth of corn, the results showed the following: -
Plant high and dry weight were decreased when irrigation done with salty water 4.0, 6.0 dS m-1 since they were 33.11 cm and 9.80 g pot-1, respectively, comparing with river water 0.92 dS m-1, which showed 33.94 cm and 10.27 g pot -1 respectively. Increasing organic extracts led to increase in dry weight, since it was 8.74 g in no- spray and increased to 11.21 g in spray level 20 g L-1., plant height increase with in organic extract spray level from 32.72 cm to 34.55 cm. Increasing salinity of irrigation water has led to a decrease in the concentration of each of the elements nitrogen and phosphorus in soil, reaching 63.74 and 1.31 mg. kg-1, respectively, comparing with control 103.71 and 2.14 mg kg-1. Potassium was non- significantly, increase was 32.37 mg kg-1 in the level of 6.0 dS m-1., comparing with irrigation with sweet water 0.92 dS m-1. Which was 24.57 mg kg-1 in the soil after planting Decrease in concentration of nitrogen, phosphorus and potassium in the dry weight of corn in the level of 6.0 dS m-1. It amounted to 10.56 and 1.97 and 32.3 mg.kg-1, respectively, an increase of salinity levels in irrigation water comparing with sweet water 11.12 and 2.76 and 4 0.07 mg kg-1 respectively.
Increase concentration of nitrogen, phosphorus and potassium when sprayed organic extracts (Peat reeds) in the dry weight of the plant maize the highest concentration 12.10, 2.90 and 38.8 mg kg-1, respectively, were obtained from comparing with control 9.45, 1.95 and 32.5 mg kg-1 respectively. Concentration of nitrogen of potassium, phosphorus, Increase in the soil after planting organic levels of organic extracts (Peat reeds) of the level 20 g. L-1, they were 96.39, 1.85 and 33.93 mg kg-1, respectively, comparing with control 69.53, 1.53 and 19.89 mg kg-1 respectively. Values of soil pH were decreased with increases of organic extract levels and irrigation water salinity they decreased from 7.65 to 7.56 and from 7.65 to 7.51 respectively. Values of electrical conductivity in the soil was increase with salinity of irrigation water it become 1.62 dS.m-1. In the level of (6.0 dS m-1). After it was 1.24 dS.m-1. In the irrigation with sweet, water 0.92 dS m-1. Value of electrical conductivity was increase when using organic extract, it decreased from decreased from 1.47 dS m-1. Spray level of 10 g L-1 of the organic extract to 1.33 dS m-1, at the level 20 g L-1.
