This study aimed to evaluate the effects of nano, bio,and conventional fertilizers on tuber yield and key agronomical traits of the Spirit potato variety.The experiment was performed using a randomized complete block design with three replicates. Sixnutritional treatments were tested: control, NPK, Mog biofertilizer, nano-chelated calcium (Nano-Ca), nano-chelated zinc + boron (Nano-Zn+B), and a complete nano-chelated fertilizer. An effectivebiplot approach (treatment × trait) was used to visualize interactions and assess relationships amongtreatments, traits, and their combined effects. The first and second principal components explained92% of the total variance. Among the measured traits; tuber weight per plant, leaf number per plant,mean tuber weight, total tuber yield, number of tubers per plant, days to flowering, dry mattercontent, and starch content, the complete nano-chelated fertilizer showed the highest performance.Based on the ideal treatment biplot model, this fertilizer was closest to the ideal position, performingbest across all traits. It proved to be the most effective treatment for maximizing tuber yield,followed by NPK, Nano-Zn+B, and Nano-Ca treatments. This study highlights the potential ofnano-fertilizers as an efficient and environmentally friendly approach to improving potato yield insemi-arid regions. The results suggest that using complete nano-fertilizers can significantly enhanceagricultural practices in such areas, leading to higher yields and more efficient resource use.","PeriodicalId":20289,"journal":{"name":"Potato Journal","volume":"52 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"http://epubs.icar.org.in/index.php/PotatoJ/article/download/166915/64956","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147891819","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Except the problem of undersized tubers this variety was either better or at par with the average performance of other varieties. K. Chipsona-1 had about 9% higher cost of cultivation than other varieties at farmers' fields. However, the gross income and net income of this variety were higher by 22% and 30%, respectively. The benefit-cost ratio for K. Chipsona-1 was 1.91 while this ratio was 1.61 for other potato varieties. Higher seed, fertilizer, irrigation and machine labour costs after adjusting for the lower cost of plant protection chemicals was responsible for overall higher cost of cultivation for this variety. Farmers got higher net profit on per unit area as well as per unit capital bases.","PeriodicalId":20289,"journal":{"name":"Potato Journal","volume":"100 1","pages":"166-172"},"PeriodicalIF":0.0,"publicationDate":"2009-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73804442","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}
