A field trial was conducted with Randomized Complete Block Design (RCBD) in three replications, at Student’s Experiment Farm, Department of Agronomy, Sindh Agriculture University, Tandojam during spring 2022-2023. The study explored the effect of foliar application of nitrogen (N) and zinc (Zn) on wheat (Triticum sativum L.) variety TD-1 on different growth stages. The treatment comprised T1 = Control, T2 = 2.0% N (tillering), T3 = 2.0% N (booting), T4 = 0.1% Zn (tillering), T5 = 0.1% Zn (booting), T6 = 2.0% N + 0.1% Zn (tillering), and T7 = 2.0% N + 0.1% Zn (booting). The results revealed that all the parameters were significantly affected (p <0.05) by foliar applications of N and Zn at both tillering and booting stages. The highest growth and yield traits were recorded when the plants were treated with 2.0 % N + 0.1% Zn applied (foliar) at tillering stage. However, the plants grown under control conditions exhibited lower performance for all the traits recorded. In conclusion, the interaction of 2.0% N + 0.1% Zn with foliar spray demonstrated positive response towards wheat variety TD-1 at tillering stage as compared to other treatments. Hence, the combined strategy of applying foliar nitrogen and zinc at tillering stage is recommended to get higher grain yields and plant growth for chaff production","PeriodicalId":411068,"journal":{"name":"Pakistan Journal of Biotechnology","volume":"41 23","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140262606","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}

Using a randomized complete block design with three replications, significant variations were discovered in days to flowering and maturity, plant height, head diameter, number of seeds per head, seed yield, and seed index, emphasizing the distinct performance of each genotype. Advanced genotypes like Sputnik and HO-1 required more days to flower, with Parson and Sputnik showing the latest maturity. Turkish plants were notably taller, while Parson had the shortest stature. Parson and HO-1 stood out with larger head diameters and higher seed indexes, with Parson also leading in seed yield, suggesting their high breeding value. Positive correlations among various growth and yield parameters underscore the potential of these genotypes in breeding programs aimed at improving sunflower yields. This concise analysis highlights the diversity and breeding prospects within sunflower genotypes, offering valuable insights for future genetic improvement efforts.","PeriodicalId":411068,"journal":{"name":"Pakistan Journal of Biotechnology","volume":"26 17","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140263823","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}
