Balady) by accessing superior earliness pure lines using an individual plant selection breeding program. Six cycles of individual plant selection were carried out at the Agricultural Experimental Station Farm at Abies region, Faculty of Agriculture, Alexandria University, Egypt, which resulted in ten pure lines with distinct horticultural traits. The selected pure lines were evaluated in the summer season of 2020 with the original population. The results showed that the pure lines L5 and L1 recorded significantly the lowest mean values compared to all the genotypes for the earliness traits, viz., days number to first flower and pod, as well as days number to 50% flowering, and days number to first harvest. Moreover, the selected pure lines significantly exceeded the original population in the characteristics of early and total yield per plant, and the three pure lines L4, L8, and L9 were the most distinguished for these traits. Concerning correlation estimates, the characteristics of earliness reflected positive and significant correlations between one another, as well as, with the characteristics plant height and early yield as the number of pods. The results of cluster analysis illustrated that the first group (I) was distinguished as being the earliest, while the third (III) and fourth (IV) clusters were the best for the productivity traits. So, it is recommended to use the pure lines L4, L8, and L9 to improve total and early yield as well as the earliness traits.","PeriodicalId":429950,"journal":{"name":"Scientific Journal of Agricultural Sciences","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129399400","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}

Phenomena such as heavy rain, drought and salt intrusion increasingly and negatively affect their crop production and productivity, with far-reaching socio-economic and environmental impacts. Reliable hydro-climatic information service received in a timely manner could help farmers improve their responses to hydro -climatic variability, thus improving their agricultural decision-making. This study aims to answer the following questions: What is the currently available technical package of BestFit Practices (BFPs)? What are the levels of application/ adoption of these BFPs among WGs in ND of Egypt? What are the relationships between the WGs' levels of application/ adoption and their characteristics? Study was conducted in 3 villages in Kafr El-Sheikh Governorate. A sample of 278 WGs was personally interviewed, by using a questionnaire designed for data collection. The most important results could be summarized as follows: Farmers perceived hydro-climatic variability as high and the quality of available hydro-climatic information as poor. They indicated a need for more accurate, time-specific, trusted and applicable information for improving agricultural decision-making. It was conclude that there is high potential and need for hydro-climatic information services tailored for farmers in the study area. The results of factorial analysis showed that there were three main factors namely: a) Efficient Agricultural Production, b) Innovative and Trustworthy Information, and c) experience-based personal influence. These three factors, together explain 52.34% of the total variance.","PeriodicalId":429950,"journal":{"name":"Scientific Journal of Agricultural Sciences","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133831414","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}
