The observed results are as follows :Significant differences are found between cultivars. (IPA99) cultivar gave the highest tolerance to water salinity and seed fracture. However، salinity levels and seed fracture caused a significant decrease in all features. As for interactions، cultivars and seed mechanical damage interactions were significant in all characteristics. While the interactions of varieties and levels of salinity were significant in the characteristics of the speed of germination and length of plumule . Interactions of salinity levels and seed mechanical damage did not reach the significant limit except for the characteristic of the plumule’s length, which reached the highest value at 7.697 cm. At the same time, the triple interactions (cultivars، seed mechanical damage and levels of salinity) were significant except for both germination percentage and pure live seed percentage. The best triple interaction was (IPA99) with 1.75 Mm and undamaged seed, which gave the best values in: germination percentage، length of plumule and radical، pure live seed percentage and seed vigor. The values of the above were as follows: 98.67%، 8.707 cm، 10.01 cm، 94.72، 18.45 respectively.","PeriodicalId":398646,"journal":{"name":"Muthanna Journal of Agricultural Sciences","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131070927","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experiment included the use of six different levels of biochar: B0 (control), B1 (1%), B2 (1.5%), B3 (2%), B4 (2.5%) and B5 (3%) were added based on the dry weight of the soil. The pots were planted with oat seeds on 1 October 2018, and after 50 days of cultivation, the studied characteristics were measured. The experiment was designed by using a complete randomized design (CRD). The results showed the improvement of the soil physical properties and plant growth with the addition of biochar, as the level exceeded 1.5% (B2) in most of the physical properties of the soil and the studied growth characteristics as it gave the lowest bulk density of soil and the highest values for the total porosity, mean weight diameter, plant height, and dry weight of plant. They were reached 1.033 Mg m-3 and 60.71 %, 1.091 mm, 60.87 cm and 2.693 g pot-1, respectively. Whereas, the 3% (B5) level of biochar recorded the highest soil moisture content and saturated hydraulic conductivity and the lowest plant height, they were reached 32.18% and 3.953 cm hour-1 and 46.90 cm, respectively. While, the control treatment (B0) gave the highest bulk density of soil and lowest values for the other studied traits compared to all levels of added biochar.","PeriodicalId":398646,"journal":{"name":"Muthanna Journal of Agricultural Sciences","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116838408","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
