Effect of Varieties and Nitrogen Fertilization on the Growth of yield XTriticosecale wittmack

Abstract

A field experiment was conducted   at the  Agricultural Research Station  /  College of Agriculture, University of Basra / Karma Ali site  in the soil of the  Grené mixture, during the  winter  agricultural season  2022-2023   , with the aim of studying the effect of varieties and nitrogen fertilization on the growth of the triticale crop triticosecale  wittmack X. The study included three varieties (Farah, Amal, Muhannad) , And four levels of nitrogen fertilizer: 0, 100,  120 and 140 kg ha^-1. The experiment was applied  according to the method of factor experiments using the of randomized complete block design  (R.C.B.D) with three replicates. Some growth characteristics were studied,include  plant height, flag leaf area and number of tiller and the biological yield and the protein yield .   The varieties differed significantly in some of the characteristics of the study, as the variety gave Amal variety the highest average height of the plant and the area of the flag paper and the number of of tiller and the biological and the protein yield and amounted to 100.13 cm and 52.92 cm ² and 615.5 tiller. m² and 22.75 Mg ha^-1 and 0.821 Mg ha^1-    respectively. The results showed that the increase in nitrogen fertilizer levels led to an increase in growth characteristics, as the level achieved 140 kg N hectare ^1- the highest average height of the plant, the area of the flag leaf, the number of tiller and the length of the spike amounted  to 106.61 cm and 50.40 cm², 704.8 m² and 11.38 cm respectively.
