The geometric model of the seed-metering device was established by SOLIDWORKS. In addition, numerical simulation tests were carried out on the seed-metering device based on CFD to verify the feasibility of the theoretical operation of the seed-metering device. The seed-metering device was processed and a test bench was built for physical testing, which verified the feasibility of the actual operation of the seed-metering device. The bench test results showed that when the fan speed reached 2100 rpm, the adsorption rate of the seed-metering device on tomato seeds, pepper seeds, and eggplant seeds reached more than 86.39%,87.22%, and 93.06%, respectively. Besides, when the fan speed reached 2400 rpm, the adsorption rate of the seed-metering device on tomato seeds, hot pepper seeds, and eggplant seeds all reached more than 95%, which demonstrated that the seed-metering device has good seed suction performance despite its straightforward design.","PeriodicalId":7435,"journal":{"name":"Agricultural Science","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41528676","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}

Once the gravity of the fertilizer in the storage box is greater than the suction of the electromagnetic sucker, the fertilizer discharging board is automatically opened for fertilizer discharge, and the metering pulse signal is accumulated once. Meanwhile, the fertilizer guide plate is driven by the electromagnetic commutator to reverse the material, and then another storage box is started for fertilizer storage and metering. In this approach, online detection of fertilizer flow can be realized by repeatedly guiding and reversing and metering the incoming fertilizer. According to the single metering fertilizer quality and the number of metering pulse signals, the fertilization amount can be calculated in real-time.The performance of the device was verified by bench test. The test results indicated that: The established fertilizer application detection model is a quadratic function (R2>0.98), and the verification error was less than 3.73% in the detection of alternating cycle fertilizer discharge; the coefficient of determination (R2) and the root mean square error (RMSE) reached 0.992 and 9.858 respectively, indicating high detection accuracy of the device is.","PeriodicalId":7435,"journal":{"name":"Agricultural Science","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45987872","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}

Dangcol, Balanga City, Bataan to evaluate the effect of bagging the whole panicle (cluster) of carabao mango fruit with waxed paper bag as compared to traditional method of bagging and without bagging in terms of fruit yield and quality as well as in cost-benefit analysis. Results revealed that fruits bagged per cluster using waxed paper (T3) obtained the highest number of marketable fruits (130.60) and highest total weight of 34.21 kg while the number and weight of XL fruits with no bag (T1) were significantly higher as compared to those bagged in cluster using waxed paper (T3). Insect damage was observed in fruits bagged per cluster using waxed paper bag (T3) while there is a scab in fruit with no bag (T1). Meanwhile, there is a wind scar observed in the two bagging methods (conventional bagging method and fruits bagged per cluster using waxed paper bag). All bagging treatments were comparable in terms of physical and chemical characteristics except for peel color which is lighter green in bagged fruits. In terms of income, mango fruits bagged per cluster using waxed paper bag (T3) had the highest gross income of PhP 3,056.27 while the highest net income and ROI was recorded in fruits bagged in conventional method (T2) earning PhP 616.09 per tree with 27.23% ROI. The conventional method (T2) also obtained the lowest cost per tree (PhP 2,262.36) while the lowest cost per kilogram (PhP 73.05) and cost per fruit (PhP 19.14) was recorded in mango trees bagged per cluster using waxed paper bag (T3).","PeriodicalId":7435,"journal":{"name":"Agricultural Science","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42978151","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}
