Weed indirectly affects the production of wheat, harboring the crop by challenging the crop for large pests, management of water intervention, reduction of grain input and efficiency, and rising processing costs. The faster growth in a thick, enclosed canopy is facilitated by a canopy, the general mechanism for improving cereal crop competition over weed species. Crop geometry is an old discipline in agriculture. It is referring to the plant's spatial arrangement and specifies the layout of the population of crops. Without concurrent grain yield loss, non-uniform geometry, such as seedling tossing, is aimed at minimizing labor intensity. Chemical and hand weeding has also been used in wheat as a weed control method. Herbicide incorporation and hand weeding greatly reduced the dry weight of weeds relative to dry weight in untreated parcels. Crop tailoring is typically calculated in three ways as a function of competition: tillering output rate, final tillering number, and tillering economy. Additional studies will help to explain the essence of the relationships of characteristics and skills in locations and seasons.","PeriodicalId":219819,"journal":{"name":"Haya: The Saudi Journal of Life Sciences","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121183085","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 median tolerance limit (LC50) were calculated using the observations made on the mortality of prawns exposed to 5 different concentrations between the No Observable Effect Concentration (NOEC) and Lowest Observable Effect Concentration (LOEC) of biocides for a period of 96 h. LC50 values for 24, 48, 72 and 96 h of imidacloprid was determined by probit analysis using SPSS version 16.0. The study revealed that the 96 h LC50 concentrations for imidacloprid as 0.009, 5.0234 and 42.611 mg/l in post-larvae (0.041 ± 0.02 g), juvenile (3.5 ± 1.5 g) and adult (17.5 ± 2.5 g), respectively of M. rosenbergii. Based on the LC50 values, safe concentrations found out for imidacloprid using Hart’s formula were 0.002, 1.000 and 15.138 mg/l, in post-larvae, juvenile and adult M. rosenbergii, respectively. The field application concentration of imidacloprid is 0.003 mg/l which is 3 times higher than the safe concentration of imidacloprid in post-larvae, whereas it is lower than the safe concentration in juvenile and adult M. rosenbergii. The results revealed that the application of imidacloprid in the paddy fields of Kuttanad has a lethal effect on post-larvae of M. rosenbergii causing a threat to the existence of species in its homeland.","PeriodicalId":219819,"journal":{"name":"Haya: The Saudi Journal of Life Sciences","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123834603","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 first origin of melatonin was detected in cyano-bacteria. As considering the endosymbiont hypothesis, cyanobacteria were engulfed by the animal and plant cells. Later on, these bacteria performed the roles of mitochondria and chloroplastids in animals and plant cells respectively. Inner matrices of these organelles are having melatonin and probable function of this intraorganelle melatonin is to protect the organelles from the detrimental effects from free radicals (Reactive Oxygen Species; ROSs and Reactive Nitrogen Species; RNSs). In higher animals, melatonin is synthesized and secreted by the pineal gland mainly during the night, since light exposure suppresses its production. Other than pineal gland, melatonin is secreted from several different organs like retina, gastro-intestinal tract. The secretion of this hormone is regulated by several environmental factors like photo-period, temperature, humidity etc. Melatonin can exert its function either by as a free molecule or by its membrane bound receptors MT1 and MT2 respectively. Modulations of melatonin receptors results in stimulation of apoptosis, regulation of pro-survival signaling, inhibition on angiogenesis, metastasis, and induction of epigenetic alteration. Melatonin could also be utilized as adjuvant of cancer therapies, through reinforcing the therapeutic effects and reducing the side effects of chemotherapies or radiation. Melatonin could be an excellent candidate for prevention and treatment of several cancers, such as breast cancer, prostate cancer, gastric cancer and colorectal cancer. This review summarized the anticancer efficacy of melatonin, based on the results of epidemiological, experimental and clinical studies.","PeriodicalId":219819,"journal":{"name":"Haya: The Saudi Journal of Life Sciences","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132860679","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 loss of PET behavior of the dye in water and the subsequent addition of urea or BSA influences the excited state nature of the dye. Urea predominantly governs the LE state nature of the dye and promotes the formation a new microenvironment in the presence of BSA. The binding constant parameters portray that dye is influenced by urea rather than BSA such that ureawater and urea-urea hydrogen-bonding assemblies predominates over hydrophobic nature of the protein.

The farmers were selected using stratified random sampling techniques. The data were collected from the study areas through questionnaires survey, focus group discussion (FGD) and cross-check interviews. Results of the study indicated that current fish production increased on an average 4300 Kg/ha/year as compared to before records (1252 Kg/ha/year ).Aquaculture contributed 29.67 percent on total annual income after participation in aquaculture. Estimated Benefit-Cost-Ration (BCR) was 3.10. A pronounced changing state on the quality and quantity of livelihoods capitals such as human capital, social capital, natural capital, physical capital and financial capital were observed comparing with the before situation. Fish consumption pattern analysis result showed that in before fish consumption quantity was on an average 33.66 gram/capita/day and that quantity rose to on an average of 63 gram /capita/day after participation in aquaculture. The estimated Head Count Poverty rate was found to be 16 percent in fish farming households as compared to 26 percent of the non-fish farming household which indicated that non-fish farming households were likely more poor than fish farming households.
