The study was conducted to determine the effects of UREA Stabil on enhancement of nitrogen utilization efficiencies of rice crop and to evaluate the influence of UREA Stabil on growth and yield of rice under waterlogged conditions of Fogera area. Treatments were comprised, control, recommended N from conventional urea (as basal and tillering), recommended N from UREA Stabil fertilizer applied once as basal, recommended N from UREA Stabil (split as basal and tillering), half below the recommended N from UREA Stabil as basal, half more than the recommended N from UREA Stabil (split as basal and tillering), half more than the recommended N from conventional urea (split as basal and tillering), half more than the recommended N from UREA Stabil as basal. Data were collected plant height, total tiller number, panicle length, number of fertile grains, thousand seed weight, grain yield, straw yield and harvest Index. Highly significantly (P<0.01) affected grain yield (3.55 t ha-1) was recorded on 136.5 kg N ha -1 in split application 45.5 kg N ha -1 as basal and 91 kg N ha -1 tillering stage from UREA Stabil source. Conventional urea source of N, application of 136.5 kg N ha -1 in split application (45.5 kg ha -1 as basal and 91 kg ha -1 tillering stage was provided higher yield (3.14) which is statistically non-significant compared to slow-release fertilizer. The economic analysis has further revealed that application of 136.5 kg N ha -1 from UREA Stabil in split application of 45.5 kg N ha -1 as basal and 91 kg N ha -1 tillering stage provided highest net benefit of Birr 47,356 ha-1 was the most profitable treatment for lowland rice production.

The present study aimed to evaluate durum wheat genotypes using NDVI under drought condition and investigate its association to grain yield. NDVI scores taken at different growth stages for 64 durum wheat genotypes were replicated twice in both sandy clay and clay textured soils situated at the same geographic location of Debre-Zeit Experimental Station, Ethiopia during 2016 rainy season; also, Green Seeker (Hand held) was used to measure the quantity of photosynthetically active pigments in leaves. Measurements of NDVI were made four to five times on sunny days between booting to physiological maturity. Analysis of variance showed significant variation among genotypes at 0.01% on NDVI values across all growth stages except at physiological maturity in both sandy clay and clay soils. The NDVI scores were highly significantly associated with yield at grain filling and anthesis stages in both soil environments. Overall, it is possible to suggest that use of NDVI would help complement identification of drought tolerant genotypes on durum wheat.","PeriodicalId":7675,"journal":{"name":"African Journal of Plant Science","volume":"11 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88481768","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}

Despite many benefits, it still considered an orphan crop in Africa. Very little information is available on the potential and production of pumpkin in Africa due to neglect by researchers and improvement program. Classical research, both theoretical and empirical, was used to conduct a systematic review of the various result trends obtained by researchers in relation to the topic. Using Google Scholar, relevant literature was selected, analyzed and summarized. In Africa, the fruit, seeds and leaves of the pumpkin is consumed. This dietary diversity of pumpkin could contribute to the improvement of people's livelihoods. Countries such as Morocco, South Africa and Tunisia are making considerable profits from the export of pumpkin. However, its production is very low because its potential is not fully exploited. In this context, research and development strategies must be put in place so that pumpkin becomes part of the African diet. The diversity, origins and distribution, utilization patterns, relative importance, production and bottlenecks of pumpkin in Africa are reviewed. These results can be used as a basis for further research on yield improvement and pest management.","PeriodicalId":7675,"journal":{"name":"African Journal of Plant Science","volume":"17 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89539683","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}

Individual interviews were conducted in 119 farms using a pre-tested questionnaire and field observations during a survey in major banana growing regions. Results indicate that FW is widely distributed across the banana growing areas with more occurrences (70%) in Kapchorwa district and majority of respondents (63.4%) reported increasing disease prevalence. A chi-square test performed revealed significant association between FW incidence and plantation age with more incidences (51.6%) recorded in older plantations (>20 years of establishment) than newly (1-5 years) established ones (11.1%). FW incidence was significantly associated with plantation management with higher incidences (86.9%) recorded in well managed plantations. Half of interviewed farmers could explain and distinguish symptoms associated with FW from other diseases, but only 38.4% of these could tell how the disease spreads; thus, a need for more concerted efforts in building the capacity of farmers to identify the symptoms and spread of FW for effective management program. We identified preliminary evidence that field abandonment is sometimes used as a last option for coping up with FW. Understanding the mechanism behind this requires more detailed research as well as establishing how farmers are managing FW culturally.","PeriodicalId":7675,"journal":{"name":"African Journal of Plant Science","volume":"185 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80582464","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}
