aluation the Yield and yield components of some hard wheat genotypes at EL-Gouba in Al-Jabal Al-Akhdar conditions

Abstract

Two field experiments were carried out inAl-Quba Al-Jabal Al-Akhdar in loamy loam soil of 7.76 pH,rising 558 meters above sea level, located at latitudes 510 320 N and 050 220 E. The soil contains 0.22% of total nitrogen and 1.47% of organic matter and about 11 ppm of phosphorous to evaluate the grain yield and its machinery for several compositions introduced from the Dry Agriculture Research Center (ICARDA) in the programs of raising wheat cans. Agduguz, Bahij, Adnan, strains 5, 9, 14, 16 and research 205 during the first study seasons 2014-15 and 2016-17 under the rain regime of 412,391 mm for both seasons in order and insufficient rains for the 2015-16 season due to the delay of precipitation until a month January, the average did not exceed 278 mm. The study was designed by randomized complete block (RCBD) in 4 replicates. The results showed that strain 9, 14 in plant height with no difference in the compositions in the number of active errors / m2 for the two seasons of study, strain 9 and Karim early in the date of expulsion and the structures Adnan and Karim for the date of noise for the first and second study seasons. The 16 Beltagl strain outperformed in weight the Sunbulah beans for the first and second seasons, respectively. The compositions did not differ in the biological yield, the grass crop in the first and second seasons, but the superiority of the compositions of strain 9 for the cereal crop was 3 ton/ha compared to the Moroccan 0.7 ton/ha for the first season. The second season’s pods were not significant. The superiority of the cream formulations versus the 29.49gm cultivar for the Moroccan in the first season and the insignificance of the differences in the second season. The cream formulation was superior in grain protein content by 13.33% in the first season and there was no significant difference between the formulations in the second season. As an extract of the highest grain yield of strain 9, despite the distinction of cream compositions in the harvest guide, the weight of 1000 grains, the protein content of grains.
