摘要

2022年春季，在伊拉克克尔巴拉Al-Hussainiya区Ibn Al-Bitar职业预备学校的田地里，采用因子排列的随机完全区组设计（RCBD）进行了一项不同施肥水平的高粱田间试验，共有三个重复和两个因子。第一个因素包括三个高粱品种（V1=Al-Khair，V2=Rabeh和V3=Bohuth-70），第二种是氮和生物肥料的组合（F0=320 kg ha-1的推荐剂量，F1=3/4的氮与固氮菌推荐量，F2=1/2的N+固氮菌推荐剂量，F3=1/4的N+硝化菌推荐剂量和F4=固氮菌+无氮肥）。结果表明，高粱品种博胡特70的株高（204.63cm）、单株叶数-1（9.807）、千粒重（35.27g）和籽粒产量（6.192Mg.ha-1）均显著提高。然而，栽培品种Al Khair的平均叶面积（4929平方厘米）和人均粒数（4428粒/头-1）最高。品种Rabeh表现优异，茎粗（24.67mm）和头长（31.29cm）的平均值最高。F0处理推荐剂量N 320 kg ha-1在叶数（9.867叶-株-1）、茎径（24.8 mm）和籽粒产量（6.145 Mg.ha-1）方面显著优于F0处理。在株高（166.57cm）、叶面积（4936cm2）和粒数（3916粒头-1）方面，用Aotobacter处理推荐剂量的3/4的N的F1处理表现优异。然而，推荐剂量N+Aotobacter的1/2的F2处理在头长（30.18cm）和1000粒重（29.93粒）方面显著优越。在交互作用方面，F0处理的高粱品种Bohuth70的单株叶数（10.33片）和籽粒产量（7.157 Mg.ha-1）表现优异，而F1处理的品种Al Khair的茎径（26.70 mm）和叶面积（5164 cm2）表现优异。2022年春季，在伊拉克克尔巴拉Al-Hussainiya区Ibn Al-Bitar职业预备学校的田地里，采用因子排列的随机完全区组设计（RCBD）进行了一项不同施肥水平的高粱田间试验，共有三个重复和两个因子。第一个因素包括三个高粱品种（V1=Al-Khair，V2=Rabeh和V3=Bohuth-70），第二种是氮和生物肥料的组合（F0=320 kg ha-1的推荐剂量，F1=3/4的氮与固氮菌推荐量，F2=1/2的N+固氮菌推荐剂量，F3=1/4的N+硝化菌推荐剂量和F4=固氮菌+无氮肥）。结果表明，高粱品种博胡特70的株高（204.63cm）、单株叶数-1（9.807）、千粒重（35.27g）和籽粒产量（6.192Mg.ha-1）均显著提高。然而，栽培品种Al Khair的平均叶面积（4929平方厘米）和人均粒数（4428粒/头-1）最高。品种Rabeh表现优异，茎粗（24.67mm）和头长（31.29cm）的平均值最高。F0处理推荐剂量N 320 kg ha-1在叶数（9.867叶-株-1）、茎径（24.8 mm）和籽粒产量（6.145 Mg.ha-1）方面显著优于F0处理。在株高（166.57cm）、叶面积（4936cm2）和粒数（3916粒头-1）方面，用Aotobacter处理推荐剂量的3/4的N的F1处理表现优异。然而，推荐剂量N+Aotobacter的1/2的F2处理在头长（30.18cm）和1000粒重（29.93粒）方面显著优越。在交互作用方面，F0处理的高粱品种Bohuth70的单株叶数（10.33片）和籽粒产量（7.157 Mg.ha-1）表现优异，而F1处理的品种Al Khair的茎径（26.70 mm）和叶面积（5164 cm2）表现优异。

ROLE OF BIO-AZOTOBACTER AND NITROGEN FERTILIZERS ON GROWTH AND YIELD TRAITS OF SORGHUM (SORGHUM BICOLOR L.)

A field experiment on sorghum (Sorghum bicolor L.) with diverse levels of fertilization, carried out in the spring of 2022 in a randomized complete block design (RCBD) with factorial arrangement, had three replications and two factors at the field of Ibn-Al-Bitar Vocational Preparatory School, District AlHussainiya, Kerbala, Iraq.

期刊介绍： The SABRAO Journal of Breeding and Genetics is an international journal of plant breeding and genetics research and was first published in 1969. It is the official publication of the Society for the Advancement of Breeding Research in Asia and Oceania (SABRAO). Its objectives are to: promote the international exchange of research information on plant breeding and genetics, by describing new research findings, or ideas of a basic or practical nature; and be a medium for the exchange of ideas and news regarding members of the Society. The Journal gives priority to articles that are of direct relevance to plant breeders and with emphasis on the Asian region. Invited for publication are research articles, short communications, methods, reviews, commentaries, and opinion articles. Scientific contributions are refereed and edited to international standards. The journal publishes articles for SABRAO members mainly. The Journal preferred strongly that at least one author should be a current member of the Society. Non-members may also publish in the journal.
