Effect of Tillage Systems in Yield of Genotypes of Barley in Two Agricultural Locations

Abstract

The study included two ways , first evaluate of twenty four genotypes performance of Barley ( Eighteen in produced genotypes which are advanced lines from selection program by method of pedigree in isolated filialles for crosses introduced from (ICARDA) with six local varieties Shuaa , Boraq , Emal , Samir , Warkaa and Al- khair) , obtained from Ministry of Science and Technolog- Salahaldeen province , to know its stability in way of cultivate it in three tillage system (Deep moderate and without tillage) in tow locations , first in one farmers field in Tuz location , the second in field crops station-college of Agriculture . Tikrit University in 2013-2014 season used (RCBD) Randomized Complete Block Design in split plots system , the main plots were Tillage and the sub plots were the genotypes with three replicates . Study of traits, duration from planting till flowering , plant height , flag leaf area , number of Spikes/m2, number of grains in the spike , weight of 1000 grains yield and biological yield . effect of system tillage distinguished deep moderate in tow trait number of grains in the spike and biological yield and without tillage in flag leaf area and weigh of 1000 grains yield and no tillage in number of grains in the spike and no significant differences between tillage system of some traits . the genotype (JH20) was distinguished in duration to flowering traits (103.39 day) and the genotype (warkaa) in two traits plant height traits and leaf area (102.60cm and 31.21cm2)respectively and the genotype (JH05) in trait of weight of 1000 grains (56.59gm), and the genotype (JH15) in trait number of grains in the spike (378.94gm) and the genotype (JH21) in two traits of grain yield and biological yield (5558.03 and 15209 kg/h) respectively , of effect locations was distinguished Toz location of all traits on the Tikrit location , and the interaction significant of all traits .
