The objective of this study was to determine seed potato handling practices and quality of farm saved seed potato. A survey involving 79 farmers was conducted in potato production areas in Kiambu and Nyandarua Counties to collect information on seed potato production practices including sources of seed tubers, seed selection, seed tuber storage, pests and diseases. Samples of seed potato were collected from farmers and evaluated for quality parameters such as tuber size, weight, stout sprout length and infection with diseases. Factors affecting potato production included limited quality seed supply, pests and diseases. Shangi was the main potato variety grown by majority (62.8%) of farmers and all the farmers used own farm saved seed. Most (45.5%) farmers recycled the seed for four seasons and 44.1% of farmers stored seed potato for three months. Freeness from seedborne diseases was the main seed quality preference by farmers. The main pest reported was cutworms (42.6% of farmers) while potato late blight and bacterial wilt were the major diseases reported by 87.1% and 86.7% of the farmers respectively. All farm saved seed potato samples were infected with Fusarium coeruleum, 51.2% with Rhizoctonia solani, 53.3% with Fusarium sambunicum, 33.3% with Fusarium solani and 48.3% with Aspergillus niger. Over 69% of the farm saved seed samples were infected with Ralstonia solanacearum while 40.1% were infected with Potato Virus S, the most dominant. Due to poor post-harvest handling practices, farmers incurred seed quality and quantity losses in storage. Farm saved seed is contaminated with multiple seed borne diseases. Farmers should be sensitized on appropriate seed potato handling practices and there should be increased supply of certified seed potato.","PeriodicalId":23702,"journal":{"name":"World Journal of Agricultural Research","volume":"8 1","pages":"20-30"},"PeriodicalIF":0.0,"publicationDate":"2018-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74258633","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 species is failing to regenerate in spite of reasonable seed production. Therefore, in order to augment the natural regeneration, special attention needs to be given for its propagation. Thus, vegetative propagation is a better option, as it ensures purity of clonal or true-to-type propagation of elite tree. The present investigation was conducted to study the effect of maturity stage of donor plants on rooting of branch cuttings of Diploknema butyracea. Mature and juvenile branch cuttings of 2-3 cm diameter and 16-20 cm length classes were planted in the non-mist propagation chambers for sprouting and rooting of cutting. Maximum 92.20% sprouting was observed in juvenile cutting which got reduced to 37.20% in mature donor plants. The maturity stage of the donor plant had significant effect on the mean length and mean number of sprouts per cutting. Maximum (3.63) mean number of leaves was recorded in juvenile cuttings. Percent rooting decreased as age of the donor plants increased. Maximum (66.70%) rooting was observed in juvenile branch cuttings which decreased to (4.40%) in cutting collected from mature donor plants. Juvenile branch cuttings showed significant survival percentage (87.80%) and survival percentage during hardening (77.80%) than mature ones. Maturity stage had a significant effect on the mean number and mean length of roots per cutting after 64 days of planting.","PeriodicalId":23702,"journal":{"name":"World Journal of Agricultural Research","volume":"18 1","pages":"15-19"},"PeriodicalIF":0.0,"publicationDate":"2018-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79548022","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}

However, it is rather difficult to evaluate such yield losses in real world situations in farmers’ fields, especially across large areas. State-of-the-art technologies, such as remote sensing and crop modeling, can offer solutions for evaluating the heat-induced yield penalty in rice across a spatial area. Remote-sensing technologies, especially Synthetic Aperture Radar (SAR), can provide spatial detection of the start of the rice-growing season. This information, combined with time-series temperature data, can be assimilated into a crop simulation model, which can provide a thorough assessment of any heat-induced yield penalty over a specific geographic region. In this paper, we demonstrate how SAR can be used to assess the effects of heat stress in rice in two districts of Andhra Pradesh, India, during the 2017 rabi (dry) season. The accumulated data suggest that 53,623 and 21,436 ha of rice fields in Nellore and West Godavari districts, respectively, had yield losses due to heat stress. Rice fields in Nellore suffered higher yield and production losses due to heat stress because of steeper trend of increasing temperatures during the rice plants’ reproductive stage.","PeriodicalId":23702,"journal":{"name":"World Journal of Agricultural Research","volume":"28 1","pages":"10-14"},"PeriodicalIF":0.0,"publicationDate":"2018-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81486094","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}

To enhance sustainable exploitation, grass cutter farming is desirable but large percentage of the population still lack awareness about grass cutter rearing. This study was aimed at investigating factors influencing awareness about grass cutter farming in Kwara state. A two–stage sampling technique was used to select 540 participants from rural and sub-urban households for the study. Descriptive statistics and binary logistic regression model were used to analyze the data. The results showed that the respondents had an average age of 46 years with an average family size of 7 persons. Majority (77%) of the respondents were males. The Nagelkerke R2, explained 80.9% of the total variation in awareness of households. The coefficient of age, gender, household size, education, and access to credit with the t-values of -2.333, 1.959, 2.000, 2.235 and 13.832 respectively were all found to be critical in explaining awareness among the sampled households. Based on the findings of this study, it was recommended that any intervention strategy on grass cutter farming by government and international development agencies should have a capacity-building component center on educating households about the management practices and livelihood merits of farm grass cutters. Increase awareness through media should be promoted and policies like loan schemes that would substantially improve households’ access to use and acquisition of credits should be encouraged.","PeriodicalId":23702,"journal":{"name":"World Journal of Agricultural Research","volume":"290 1","pages":"299-304"},"PeriodicalIF":0.0,"publicationDate":"2017-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86429288","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}
