Effect of Heat Accumulation on Spike Length and Its Weight of Three Wheat Cultivars Irrigated With Different Quality and Magnetic Intensity

journal of kerbala university, 2016, Volume 12, Issue 0, Pages 9-22

An experiment was conducted in a field belonging to the Technical Institute-Kufa during the season of the year (2013 – 2014) to determine the effect of heat accumulation in spike length and weight of three bread wheat (Triticum aestivum L.) cultivars irrigated with different water quality and magnetic intensity. The experiment was arranged as sub-sub plot design within Randomized Complete Blocks Designed (RCBD) with three replicates of each treatment. Experiment included study of three factors it’s; irrigation water quality (river water or well water)- Main plot, wheat bread cultivars (IPAA–99, Rashid and Tamuze–2)- Sub-plot and magnetic treatment of irrigation water four intensities (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.
The results showed that exponential proportionality for spike length and weight by the effect of study factors with the different heat accumulations increased, as well as, the well water significant superiority on river water when heat accumulations (560.05 and 742.80)ºC compared with ultimate superiority of the river water that gave high means of traits at harvest season (1188.55 ºC).
