Farmers much attention to ordered high seed quality, which is associated with many important agronomical traits and can arise in a 30% increase in crop yields. By boosting germination, the seed coating technique increment yield, and seed quality. Moreover, seed coating is a desirable option as a tool for boost establishment of crops by speeding up difficulties that systems of agriculture face. The purpose of the experiment was to contrast the efficacy of seventeen natural compounds seed coating treatments namely (T1) Control seed without coating, (T2) Seed coated with arabic gum, (T3) Water only, (T4) Indole butyric acid IBA 100 ppm, (T5) Kaolin 6%, (T6) Glycine betaine 100 ppm, (T7) Sorbitol 1%, (T8) IBA+ Kaolin, (T9) IBA+GB, (T10) IBA+ Sorbitol, (T11) Kaolin + GB, (T12) Kaolin + Sorbitol, (T13) GB + Sorbitol, (T14) IBA + Kaolin + GB, (T15) IBA + GB + Sorbitol, (T16) Kaolin + GB + Sorbitol, (T17) IBA+ Kaolin + GB + Sorbitol. Results revealed that high chlorophyll content and crop growth rate were achieved when seed coating with T15 and T17. The tallest plants were recorded at T6 while T8 and T14 achieved the heaviest seed weight,100 seed weight, and number of pods per plant. T12 achieved a high number of seeds per plant. T8 recorded high seed yield per feddan, high germination percentage, and seedling dry weight, while T17 recorded the longest seedling length. T5 recorded high protein content and T15 achieved high carbohydrates and oil content. Thus, seed coating technologies enhance seed performance, and improve crop establishment, for sustainable agricultural systems. All seed-coating compounds are safe for both the environment and human health.","PeriodicalId":11513,"journal":{"name":"Egyptian Journal of Agricultural Research","volume":" 44","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138612310","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 structure of achieved compounds was identified by conducting a series of spectral and physicochemical techniques. A mixture of distilled water and DMSO was used for preparing four different concentrations of the tested compounds; (50, 100, 200 and 300 ppm), which were then used in treating Eobania vermiculata under laboratory conditions. The thin-layer film technique was utilized for performing the in vitro treatments. The sub-lethal concentrations; (LC 25 and LC 50 ) values were estimated. The investigated chemical compounds displayed remarkable toxicological effects against the screened brown garden snails. Eobania vermiculata species showed the highest sensitivity level toward Ni(II) complex (LC 50 = 53.55 ppm). However, the (HL) ligand displayed a higher toxicity against Eobania vermiculata than Co(II) complex (LC 50 = 87.92 and 95.59 ppm, respectively). The investigated land snails were treated in vitro with the LC 25 concentration of the obtained compounds for 7 days to evaluate their efficacy on the shell of those species. The level of some elements composing the snail shell; calcium, magnesium, phosphorus and potassium, was assessed. The obtained data emphasized that the tested compounds caused a considerable decrease in the level of estimated shell elements.","PeriodicalId":11513,"journal":{"name":"Egyptian Journal of Agricultural Research","volume":"108 22","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138607690","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}

To assess the physiological quality of seeds, various vigor tests were utilized. Laboratory and field experiments were conducted at the Seed Technology Research Department (STRD), Agricultural Research Station in Tag El-Ezz, Dakahlia Governorate during the winter seasons of 2019/2020 and 2020/2021. Using less robust seeds can result in a yield reduction of up to 27%. Laboratory tests, such as standard germination (SG), seedling length (SL), seedling dry weight (SDW), seedling vigour index (SVI), accelerated aging test (41°C for 48 h), and electrical conductivity test (EC), were conducted to assess the vigour of wheat seed lots. These tests successfully detected variations in vigour among the different seed lots. Also, a field study was conducted to estimate field emergence. The appropriate test for estimating field emergence was determined using correlation coefficients. The findings showed that most vigor tests were helpful in classifying seed lots based on the physiological stage of deterioration. Standard germination (SG), Electrical conductivity test (EC), and Accelerated aging provided the best estimate for the viability of seed lots and prediction of wheat variety emergence in the field. The electrical conductivity test and aging test were found to be the most effective in assessing the quality of wheat seeds and predicting their field emergence as seedlings. There was a strong correlation between these vigor tests and field emergence. Therefore, it is recommended to use the electrical conductivity test and accelerated aging test to rank seed lots and predict their field emergence, seedling establishment, and overall performance. These tests have proven to be reliable indicators of wheat seed emergence potential.","PeriodicalId":11513,"journal":{"name":"Egyptian Journal of Agricultural Research","volume":" 46","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138620365","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}

Analysis of variance for randomized complete block design with four replications was done for each location. Then combined analyses of variance were calculated for eight cultivars, seven locations over two growing seasons . The statistical analysis for phenotypic and genotypic stability was carried. Concerning Giza 86, Giza 87, Giza 88, Giza 92 and Giza 93 cultivars which are considered the most desired cultivars occupy the most areas cultivated by high production of seed cotton and lint cotton yields. However, Giza 96 had the widest range of environmental index for seed cotton yield and lint cotton yield. While Giza 45 had the closest one for seed cotton yield and lint cotton yield. The environments were the most important source of variation explaining 91.92% and 90.92% of the variance for seed cotton yield and lint cotton yield, respectively, followed by the cultivars which explained 5.37% and 6.35% from the source of variation for seed cotton and lint cotton yields, respectively and the interaction between the cultivars and environment represented 2.71% and 2.73% from the source of variation for the two traits, respectively. With respect to the two cultivars, Giza 87 and Giza 88 their bi values do not significantly differ from the unity (bi = 1) and had deviation from regression ( S 2 di) not significantly differ from zero and their lint cotton yields exceeded the average overall genotypes, which indicated average stability and relative adaptability of the cultivars pointed out. The great variation of the cultivars to the estimated λi statistics suggested that the relatively unpredictable components (the deviation from the linear response) of the cultivar x environment interaction variance may be more important than the relatively predictable component (the coefficient of linear response). Results illustrated that all studied cultivars for both seed cotton and lint cotton yields are sensitive to environmental changes and these cultivars are expected to give high yields either for seed cotton or lint cotton under favorable environmental conditions.","PeriodicalId":11513,"journal":{"name":"Egyptian Journal of Agricultural Research","volume":"98 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138623159","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}
