| Abstract | ||
| The present research was carried out in the Experimental from Agriculture Research Station, Desert Research center, at El- Quntra East, North Sinai Governorate, Egypt, in the period 2017-2018 and 2018-2019 to study the effect of three seeding rates (45,55and 65kg/fed), and three levels of humic acid application (0,4and 8 kg/fed) on the yield and yield components of some triticale genotypes (T11, 8, ICBA triticale and T6). A split split plot design with three replication was used, where the genotypes of triticale were arranged in the main plots, seeding rates were placed in the sub plots while humic acid application were allocated randomly to the sub-sub plots. Results indicated that Triticale 11 genotype with sowing at 55 kg/fed and 8 kg HA levels gave the highest values of number of plants/m2, tillers and spikes/m2, grain and straw yields kg/fed in both seasons. Triticale11 genotype significantly surpassed the other three triticale genotypes (ICBA, t8, t6) for all studied characters in the first and second seasons respectively. Pearson’s correlations analysis showed that GY was significantly and positively correlated with all studied traits except cropping index (p < 0.01). Principal component analysis revealed that the first main PC (PC1) had eigenvalues greater than one ((6.689) and contributed 95.6% of the total variation existing among studied traits regarding seeding rate, humic acid rate and variety variables. The contributions of PC1 to the total variance were higher than that of PC2 (3.10%). | ||
