The factor that influences the production of shallots is fertilization. Shallots need fertilizer and sufficient nutrients to increase growth and production. This research method uses factorial randomized block design (RBD) consisting of 2 factors, 16 combinations, and 2 replications. The first factor is cow manure compost with the symbol \"K\" consisting of 4 levels K0 = 0 g / plot (control), K1 = 1 kg / plot, K2 = 2 kg / plot and K3 = 3 kg / plot. Liquid organic fertilizer (LOF) fruits with the symbol \"C\" consist of 4 levels C0 = 0 ml / L water / plot, C1 = 250 ml / L water / plot, C2 = 500 ml / L water / plot and C3 = 750 ml / L water / plot. The results showed that the administration of cow manure compost did not significantly affect the parameters of the number of leaves per sample, a number of tillers per sample, but significantly affected the production of wet tubers, dry tubers production, and conversion of shallots production, fruit LOF did not significantly affect all parameters namely number of leaves per sample (strands), a number of tillers per sample, wet tuber production per dry tuber per sample, conversion of shallots production. used in the studies is a short-lived plant.

The present study investigated the particle size of biochar on the sorption of ammonium N (NH 4+ -N), nitrate N (NO 3- -N), phosphate P (PO 43- ), and iron (Fe 3+ ). Four biochars were produced from oil palm empty fruit bunch (EFB), oil palm kernel shell (KRN), rice husk (RH), and bamboo (BMB), which sieved into two groups with particle size of 1-2 mm and <0.3 mm. Biochar physical and chemical properties were determined. The ability of biochars to adsorb NH 4+ followed: BMB > RH > EFB while no sorption was observed in KRN. The sorption characteristics of NH 4+ were well fitted to the Freundlich isotherm model. Overall sorption of NO 3 - favours fine particle and were well-fitted into Langmuir model followed the maximum sorption capacity of: BMB > EFB > KRN > RH.

By combining the PM 2.5 data retrieved from MODIS satellite and the population spatial distribution data in the Yangtze River Delta which were estimated by the random forest model with the night light, vegetation index, elevation and slope of satellite remote sensing, the population exposure intensity of PM 2.5 and the risk of lung cancer death in 2013 were calculated. The results show that the spatial distribution of PM 2.5 population exposure intensity is spatially discontinuous, which is consistent with the spatial distribution of population but inconsistent with the spatial distribution of PM 2.5 concentration. Generally, the regions of high exposure intensity include Shanghai, most of Jiangsu Province, the central and southern half of Anhui Province and some coastal cities in Zhejiang Province. The lung cancer deaths caused by PM 2.5 pollution are consistent with the spatial distribution of PM 2.5 exposure intensity. Among the four major cities, relative to the baseline situation, the largest increment in lung cancer deaths caused by PM 2.5 in 2013 is in Shanghai (1565), and the smallest is in Hefei (570).

Sowing times of rice in Bhutan are often driven by the monsoon and are frequently delayed with no specific varieties developed for delayed sowing. Thus, the research was conducted at ARDC-Samtenling research station in 2017 to study effect of sowing dates on performance of widely adopted Bhur Kambja1 rice variety to identify zonal specific optimum sowing window. Field experiment was laid out in a randomized complete block design with three replications having net plot size of 5 × 2 m. Experiment comprised of five different sowing dates that are 30 th May, 14 th June, 29 th June, 14 th July and 29 th July at an interval of 15 days. Some agronomical traits such as plant height, days to maturity, number of productive tillers per hill, panicle length at harvest and grain yield were measured and analyzed. The result indicated that effect of sowing dates on plant height, days to maturity, panicle length and grain yield were statistically significant at 0.05 probability level while number of productive tillers per hill showed no significant differences among different dates of sowing. Sowing at 30 th May and 14 th June resulted significantly higher yield of 3.53 t ha -1 and 3.40 t ha -1 respectively. The findings revealed that sowings at 29 th June, 14 th July and 29 th July yielded low of 2.37 t ha -1 , 2.97 t ha -1 and 2.83 t ha -1 respectively. This elucidates that late sowing and transplanting cause yield reduction which could not be recommended among farmers.","PeriodicalId":182275,"journal":{"name":"International Journal of Agriculture and Environmental Research","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132341930","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}

It also associated with increased somatic cells in milk, these cells include; neutrophils, macrophages, lymphocytes, and mammary epithelial cells. They are used as an indicator to monitor udder health status of dairy cattle. Somatic cell count has higher heritability as compared to mastitis, thus it can be used as a trait for selection of mastitis resistance. The objective of this study was to evaluate genes associated with mastitis in crossbred dairy cattle. Blood samples were collected from 96 crossbred cattle for DNA analysis, and a total of 152 milk samples were collected from full udder quarters of 38 lactating crossbred dairy cattle for SCC analysis. Genomic DNA of beta-lactoglobulin and lactoferrin genes were amplified using two pairs of oligo primers 252 bp and 301 bp respectively. Their amplified products yielded 27 fragments at the 301-bp and 23 fragments at 252-bp. Results of PCR-DNA sequencing found out that there were several genetic variations in sequences, which were identified as Single Nucleotide Polymorphism (SNPs) associated with mastitis susceptibility. This study strongly suggests that beta-lactoglobulin and lactoferrin are novel candidate genes for selection of mastitis resistance in crossbred dairy cattle.","PeriodicalId":182275,"journal":{"name":"International Journal of Agriculture and Environmental Research","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114960054","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}

Growth parameters and concentration of cadmium in plant tissues was measured. The results showed that for the two varieties of maize Hudeiba one and Hudeiba two seeds have ability to germinate and grow under different concentration of cadmium. Also it was found that cadmium affected the most growth parameters such as leaves area, fresh shoot weight, fresh root weight, dry root weight and dry shoot weight in all treatments. The results also indicated that the two varieties of maize (Hudeiba one, Hudeiba two) seedlings and plant, can uptake cadmium element from contaminated soil with different concentration levels up to 100 mg/kg-1. The results indicated that low concretion levels of cadmium up to 100mg/L can enhance the germination of seeds.
