Two hundred genetically improved farmed tilapia (GIFT) fingerlings were grown in the fish tanks. Four types of media, viz., 20mm gravel (M1), 8-20mm broken tiles (M2), 8-15mm hydroton (M3), and 8-10mm gravel (M4), were filled in the media beds. The two varieties of tomato, Manulakshmi and Yakamoz RZ, were raised. Plant height, plant spread, days to first flowering, days to first harvest, total yield, and average fruit weight were observed to compare the crop performance in each media and identify the best-performing media in an aquaponics system. \u0000Results: During the first and second seasons of Manulakshmi in the aquaponics system, plants grown in 8-10mm gravel exhibited significantly superior results than all other media. The maximum plant spread (66.833cm), plant height (140.556cm), total yield (1.730Kg), and average weight of fruit (38.433g) were observed in 8-10mm gravel during the first season. In the second season of Manulakshmi, the observed plant spread, plant height, total yield, and average weight of fruit were 140.778cm, 66.556cm, 1.729Kg and 38.611g, respectively. In the first season of Yakamoz RZ in the aquaponics system, maximum plant height (145.222cm) and total yield (3.871Kg) were observed in 8-10mm gravel, whereas maximum plant spread (50.500cm) was observed in 20mm gravel. The days to first flowering and days to first harvest were comparatively shorter in 8-10mm gravel in both varieties. \u0000Conclusion: Plants grown in 8-10mm gravel exhibited superior results than all other media. Variations of plant characteristics among different media in the aquaponics system reveal that 8-10mm gravel is more favorable for the growth and yield of tomato plants than other media.","PeriodicalId":14186,"journal":{"name":"International Journal of Plant & Soil Science","volume":" 21","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141671545","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}

Over-exploitation of soil by farmers leads to soil degradation such as acidification or organic matter lost. To find sustainable soil fertility management techniques, three types of organic matter (compost, compost combined with fungi, bacteria and yeast, and biochar) were applied to the soil. This study evaluates and compares the effect of various organic amendment on the soil fertility under pepper. A field trial was carried out in a randomized block design with four treatments (T0, T1, T2 and T3) and repeated three times in the Agboville department, located in Côte d’Ivoire. Growth and productivity parameters were measured during the experiment. At the end of the experiment, soil and plant samples were taken for chemical analysis and to determine soil fauna. The results show that the various treatments had little impact on soil chemical parameters. As for the soil fauna, results indicated a low level of biological activity under all treatments. However, a comparison of organic matter types shows that the compost-based treatment (T1) had a relative positive impact on pepper growth and production parameters, compared with the biochar treatment (T3), microorganism-based compost (T2) and control (T0) treatments. With a view to intensifying pepper production, it would be advisable to continue this work with long-term experiments while increasing the doses of organic matter applied to the soil.","PeriodicalId":14186,"journal":{"name":"International Journal of Plant & Soil Science","volume":" 20","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141676100","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 revealed the presence of significant differences among the genotypes for all the traits under study. Genotypic and phenotypic coefficients of variances were high for number of productive tillers per hill and grain yield depicting the wide range of variation for these traits. High heritability allied with high genetic advance over mean was seen for the traits like plant height, number of tillers per hill, number of productive tillers per hill, panicles per sqm, grain yield, grain iron content, zinc content and protein content indicating the preponderance of additive gene action and least influence of environment on these traits, thus, they possess better scope for improvement through selection. The correlation analysis revealed the negative significant association of grain yield with grain zinc content and negative non-significant association with all other quality traits. Validation of the putative markers is generally carried out to check the reproducibility of those markers. SSR markers RM211 and RM242 were validated for grain iron content, RM303 and RM234 for grain zinc content and RM23914, RM1235, RM219, RM206 and RM1337 for grain protein content.

KMR-3R is a popular restorer line used for commercial rice hybrids production. For majority of the rice ecosystems, most of the rice hybrids released using three line systems were suited for normal phosphorus conditions only which exhibits severe yield reduction under low phosphorus conditions. To facilitate the efficient use of complex polygenic traits in hybrid rice, molecular breeding approaches were developed using KMR-3R BILs with Pup1 QTL by introgression of major QTL Pup1 controlling genes yield under low phosphorus stress. Parental polymorphic survey is a pre requisite before starting marker assisted backcrossing, it is used for introgression of a desirable traits from a donor genotype into a recipient genotype. In this context, I have screened all reported SSR primers linked to low phosphorus tolerance and observed K-46-1 and K-46-2 linked to Pup1 QTL was polymorphic between Kasalath and KMR-3R. Simultaneously I have screened 300 full-genotype SSR markers covering entire genome and observed 86 SSR primers as polymorphic between Kasalath and KMR-3R. After polymorphic survey, I have evaluated Kasalath and KMR-3R.under low phosphorus stress and normal phosphorus conditions and recorded significant differences among the parents. Kasalath performed well when compared to KMR-3R for all the characters studied under low phosphorus stress conditions.
