دراسة فسلجية لتأثير الري بالماء المعالج مغناطيسيا في بعض الصفات الخضرية و الحاصل لثلاثة أصناف من الحنطة في النجف

الملخص EN

An experiment was conducted in a field belonging to the Technical Institute-Kufa / Najaf governorate during the period from 7 / 12 / 2012 until 4 / 20 / 2013 to determine the effect of irrigation water quality and intensity of magnetically treated water on some of vegetative characteristics and yield of three cultivars of wheat (Triticum aestivum L.).

Experiment designed was Randomized Complete Blocks Design (R.C.B.D) arrangement in Split split-plots and three replicates for each treatment.

Experiment included three factors : quality of irrigation water (river water and well water)-Main plot second : wheat bread varieties (IPAA-99, Rashid and Tamuze-2)-Sub-plot third : magnetic treatment to irrigation water four (0, 750, 1500 and 3000) Gauss-Sub-sub-plot.

The Revised Least Significant Difference (RLSD) at 0.05 probability was used to compare treatment means, whenever treatments affects were evident.

Results showed that plants wheat irrigated with river water superior in all parameters in forms of plant height, leaves number, leaf area, total tillers number, leaves content of total chlorophyll and hectare yield of grains.

The majority of vegetative parameters was increased with Rashid plants cultivar compared to the other cultivars.

Magnetic treatment to irrigation water by 1500 gauss revealed that noticeable superior in most of plants vegetative, while the yield characteristics had increased with magnetic water treated by 750 gauss.

The interaction between irrigation water quality and magnetically treatment gave the higest vegetative growth indicators with plants irrigated with magnetized river water (1500 gauss) while the highest yield with plant irrigated with magnetized river water (750 gauss).

The three ways interaction of experiment factors revealed a significant effect on magnetized river water by 1500 gauss in Rashid and Tamuz-2 plants cultivars giving highest vegetative growth that increased plant yield.
