Root growth of some wheat cultivars under salnity and foliar fertilization effect of some wheat varieties

Abstract

This study was carried out in Albargh district ( 30) km northern east Kerbala city during the winter season of 2013 – 2014 starting from Nov.,8th ,2013 till April,18th, 2014. The aim of the study was to improve the ability of wheat plant by the addition of Algidex as a foliar fertilizer to the irrigation with saline water and the effect of wheat cultivars and their interactions on the growth , of roots . Studied characteristics included , root,s length , volume and diameter and dry weight of roots ,. Factorial experiment within Completely Randomized Design (CRD ) was adopted. The 1st factor represented two types of irrigation water(i.e.river water and saline water) ,the 2nd factor represented three concentrations of Algidex ( i.e. 0, 0,5 and 1.0) g.l _1, and the 3rd factor represented five wheat cultivars( i.e. Iraq , IPA–95,Fateh , Sham 6 and Sali) with three replicates . The experiment was as pots experiment 7 kg soil capacity ,20 seeds were sown in each pot on Nov.8th , 2013 thinned to 7 seedlings 15 days later.Foliar application was carried out three times during the experiment period i.e. on Dec. 13th ,2013 , on Feb. 16th , 2014 and on March, 15 th, 2014. Data were statistically analyzed and means were compared using least significant difference (L .S.D) at 0.05 probability level .Results could be summarized as follow :Wheat cultivars had a significant effected on root characteristics where Fateh cultivar gave higher values of volume and diameter of roots . While Sham 6 cultivar gave higher root dry weight. The type of irrigation water significantly affected some traits where the river water gave highervalues of length , volume and diameter of roots and root dry weight . The type of irrigation water markedly affected roots characteristics where water treatment gave higher length , volume , diameter and dry weight of roots giving 37.000cm , 5.927cm3 , 1.412cm and 0.562 g respectively. Foliar fertilizer had significantly affected the root dry weight only ,where 0.5 g/l gav the highest value 0.561 comprade with the control treatment giving 0.511g . The interaction between cultivars and foliar fertilizer had a significantly effect on root's volume and root'sdry weight. The type of irrigation water and foliar fertilizer interaction had a significant effect on root's length ,root's volume and root's dry weight .The interaction between cultivars and water type significantly affected root's length ,root's volume,root's diameter and root's dry weight .The interaction between three studied factors had a significant effect on the root's length ,root's volume and root's dry weight.
