The results of this study showed that the overall means for body weight at four weeks (BW 4 ), body weight at eight weeks (BW 8 ) and body weight at twelve weeks (BW 12 ) were (204.699 and 190.02 g), (718.559 and 610.20 g) and (1289.99 and 1049.002 g) for males and females, respectively. These results showed that the differences among line were highly significant (P ≤ 0.01) in selected line than control line in BW 8 and BW 12 . Also, the overall means of shank length in eight weeks of age (SL 8 ), breast length in eight weeks of age (BRL 8 ) and breast width in eight weeks of age (BRW 8 ) were (6.81 and 6.38 cm), (11.85 and 11.23 cm) and (11.24 and 10.78 cm) for males and females, respectively.

This effect increased with increasing the concentration where 160 mg/ml of any of the tested extracts completely (100%) inhibited the fungus growth. Meanwhile, treatments with the two tested acetone algae extracts (as dipping or coating in gelatinous substance) significantly decreased dry rot disease severity on the inoculated potato with F.s. 2 under cold storage conditions (7±2°C) compared to the untreated inoculated control and the effect increased with increasing the concentration from 160mg/ml to 200 mg/ml. Also, coating tubers with the tested algae extracts was even more effective to decrease dry rot disease severity during storage. Spirulina extract treatments consistently decreased the developed dry rot severity compared to Chlorella treatments. This effect of algae extracts may be explained in view that the algae extracts treatments were accompanied with significant","PeriodicalId":21277,"journal":{"name":"Revista de Ciências Agrarias - Amazon Journal of Agricultural and Environmental Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135052498","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}
