These products are colonized by un-identified post-harvest fungi that are responsible for high post-harvest losses. The objective of the study was to contribute to the management of the post-harvest diseases of kernels of V. paradoxa and P. Biglosa through natural products. To achieve this, post-harvest fungi were isolated from infected kernels and their pathogenicity tested. Then, antifungal activity of Essential Oil (EO) of Thymus algeriensis and crude extract of African panaxia was carry out by the dispersion method on the agar medium on four pathogenic fungi isolated from the two infected ENTFP. Results showed that V. paradoxa kernels were highly infected (77-95%) compared to P. biglobosa (0.6-2.6%). Fungal species frequently associated with V. paradoxa and P. Biglobosa kernels were: Aspergillus niger (46%), Rhizopus nigricans (17%), Oidium sp (22%) and Cercospora sp (8%); and Oidium sp (55%), A. niger (18%), A. flavus (18%) and Cercospora sp (6%) in V. paradoxa and P. biglobosa respectively. Pathogenicity test was positive with all the species belonging to the genus Aspergillus and with Oidium sp. Essential oil of T. vulgaris at 1.5 �l/ml and the crude extract of African panaxia at 120 �g/ml totally inhibited the growth of the four potential mycotoxigenic fungi tested; their efficacy were significantly comparable (p<0.05) to the reference fungicide (Terazeb).

The fruit is composed of very nutritive minerals like potassium, calcium, iron, chlorine, phosphorus, and magnesium. The tree can withstand relatively harsh climate and soil conditions, which no other crop can match. In Ethiopia, date palm is cultivated and/or wildly grown in the Afar, Dire Dawa, Somali, Gambella and Benishangul Gumuz regions. However, the yields of local cultivars are too low to meet the sharply increasing demand. Thus, research has been conducted to evaluate and register the best-performing, desirable yield and quality of introduced improved varieties. Fourteen (14) tissue-cultured introduced materials from England and Israel were planted at 10m x 10m spacing between rows and plants over three locations, viz., Werer Agricultural Research Center (WARC), Assiyta, and Afambo districts. Two varieties (Barhee and Medjool), early fruiting types, were individually evaluated out of 12 varieties on the basis of fruit yield for two years at WARC, while vegetative parameters were taken from the other locations. The study revealed that Barhee and Medjool were superior to the remaining date palm varieties. The annual yield advantage of Barhee (68.39 kg tree-1 ) over Medjool (50.87 kg tree-1 ) was 34.44%. The high offshoot production potential of Barhee and Medjool varieties could reduce the purchase of imported tissue-cultured date palms by the country as well as individuals. In conclusion, the newly released varieties Barhee and Medjool could be cultivated profitably and sustainably for commercial cultivation in the low land areas of the Afar regional state and other similar agro-ecology, and could also increase the income of smallholder farmers and agro-pastoralists.","PeriodicalId":413372,"journal":{"name":"International Journal of Agriculture and Biosciences","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133458585","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 experiment consisted of four rates of nitrogen (0, 23, 46, and 69 kg ha-1) and four rates of NPS fertilizer (0, 50,100 and 150 kg ha-1). The treatments were arranged in factorial combination using randomized complete block design (RCBD) with three replications. The analysis of variance revealed that the main effects of NPS and N fertilizer rates significantly affected plant height, number of leaves plant-1 and dry stem weight plant-1. The tallest plant height (32.87 cm) and highest dry stem weight (41.86 g plant-1) were recorded from 100 kg ha-1 NPS rate. Similarly, the tallest plant (31.90 cm) and highest dry stem weight (42.78 g plant-1) were recorded from the highest (69 kg N ha-1) rate. On other hand, the interaction effects of NPS and N fertilizer rates also significantly affected number of primary branches plant-1, fresh leaf weight plant-1, fresh stem weight plant-1, fresh inflorescence weight plant-1, aboveground dry biomass and essential oil yield of basil. Significantly, the highest fresh leaf weight (319.36 g plant-1) and fresh stem weight (176.30 g plant-1) were obtained from combined application of 150 kg ha-1 NPS + 69 kg ha-1 N rates. The highest number of primary branches plant-1(12.63), dry leaf weight (43.93 g plant-1) and aboveground dry biomass (4.64-ton ha-1) were obtained from combined application of 100 kg ha-1 NPS + 69 kg ha-1 N, whereas the highest essential oil yield (30.22 kg ha-1) was due to combination of 100 kg ha-1 NPS + 46 kg ha-1 N rate and it is statistically at par with 50 kg ha-1 NPS + 46 kg ha-1 N. Therefore, combined application of 50 kg ha-1 NPS + 46 kg ha-1 N would be suggested in case of basil used for extracting essential oil.","PeriodicalId":413372,"journal":{"name":"International Journal of Agriculture and Biosciences","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134078998","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}
