Crop storage in this zone like any other tropical zone depends to a large degree on prevailing temperature and relative humidity. Agboola (1982) posited that the moisture content of crops especially grains, pulses, oil seeds e.t.c which depends on prevailing relative humidity is required to be reduced to a minimum level known as “safe level” before such crops can be successfully stored. Temperature is also an important physical factor in crop storage. Most insects and micro-organisms have optimum temperatures at which they can grow, develop and reproduce or multiply abundantly. Temperature fluctuation causes condensation and moisture migration in Silos leading to extensive mould development and caking of grains stored resulting in heavy losses.

If a watershed lacks any gaging station, thenhydrologic models can be utilized to estimate runoff. The Soil Water Assessment Tool (SWAT) is one of the most widelyusedcomputerwatershed models. In this model, we need to input meteorological data, such as precipitation, temperature, wind speed, solar radiation, and relative humidity;as well as watershed data, including curvenumberandroughness coefficient, to calculate the watershed runoff. Some watershedshave weather stations, but there is a risk that the recordeddataof a station do not represent the whole watershed and the use of such data may cause error. Consequently, the error of estimated runoff error needs to be determined. This study deals with the sensitivity of runoff estimatedusing the SWAT model to the variations in meteorological parameters, such as precipitation, solar radiation, wind, humidity, and temperature. Results indicate that with a 30% decrease in the average monthly precipitation, sunshine, relative humidity, wind and temperature, we witness,respectively,a 64.27% decrease, 114.67% increase, 45.93% decrease, 126.12% increase, and 39.21% increase in the estimated runoff.. Runoff estimation is found to be most sensitive to wind speed and solar radiation,and least sensitive to temperature.","PeriodicalId":117425,"journal":{"name":"International Journal of Research Studies in Agricultural Sciences","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124970281","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 surveyed areas were Wazntet, Awrari, Basheri, Genfelom and Hamelmalo by selecting two farms from each village. The crops were affected by different diseases such as early blight, late blight, powdery mildew, wilt, blossom end rot and leaf curl in tomato and damping off, leaf curl, bacterial leaf spot in chilies. The symptoms have been observed and compared the disease incidence and severity among the selected farms of the villages, occurred throughout the various phenological stages of the plants. The present survey revealed that there was no any significant difference between the surveyed areas, based on the diseases incidence and severity which is calculated at that particular time. Percentage of disease incidence and severity of tomato was higher in Basheri and Awrari, while the both disease intensities of chillies were recorded maximum during Qewi season in Basheri and Genfelom. In tomato and chillies, the percentage of disease incidence showed more than 77% in all villages during Hagay season but the severity was observed between 20 and 60%. The reasons for those results are low educational level, no proper irrigation, unavailability of fertilizers and lack of chemicals for controlling the diseases","PeriodicalId":117425,"journal":{"name":"International Journal of Research Studies in Agricultural Sciences","volume":"121 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123506421","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 was carried out in a simple lattice design. Univariate analysis of variance showed that there were highly significant differences among genotypes for all oil quality traits compared .The significant difference indicates the existence of genetic variability among the accessions that is important for selection and breeding program. Multivariate analyses resulted in the formation of four clusters and have shown the presence of extensive genetic diversity among the genotypes. Genetic distances were highly significant among most of the clusters. The highest genetic distance was recorded between Cluster 3 and Cluster 4 (38.2) followed by Cluster 1 and Cluster 4 (37.7), and Cluster 1 and Cluster 2 (33.3). The genetic divergence between Cluster 1 and Cluster 2, Cluster 1 and Cluster 4, Cluster 2 and Cluster 4, Cluster 3 and Cluster 4 were also highly significant. Genetic distances of land races based on seed oil quality traits between Cluster 2 and Cluster 3 were only nonsignificant, indicating close relationship among the genotypes. The present study also showed that geographical diversity could not necessarily be an index of variation and the factors other than geographic diversity such as genetic drift, selection pressure, closeness in pedigree and environment may be responsible for differential grouping of land races of genotypes of Ethiopian mustard.","PeriodicalId":117425,"journal":{"name":"International Journal of Research Studies in Agricultural Sciences","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130059977","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}
