This review article gives insights on reproductive endocrine profiling, artificial insemination (AI), in vitro fertilization (IVF) and embryo transfer in wild felid through exogenous hormonal application. Wild felids are seclusive creatures and they express slight to marked variations in reproductive mechanisms; we lack to clearly define normative data of onset of puberty to reproductive senescence and the understanding of fundamental reproductive physiology. This is crucial in many aspects of conservation in wild and captive breeding. Various researches in bits and pieces revealed that species difference with different estrus period, its length, hormone level were the keys for the failure of AI, IVF and embryo transfer in wild felids. This paper also summarizes the estrogen and progesterone monitoring in female and androgen (testosterone) in male, semen analysis and cryopreservation of sperm and embryo. Reviews of published work reports about 10 offspring born from artificial insemination and 39 offspring born from embryo transfer which are included in this article.

Total plant biomass was 106 gplant-1 at 4.4 kg B ha-1 compared to 79 g plant-1 at the control of no nutrient inputs. Relative to the control treatment, there was a two-fold increase in fresh curd yield at 1.1 Kg B ha-1 application. Boron application improved the shoot B content as well as its partitioning towards curd and was associated with higher B concentration in the curd. While the soil residual B was 0.26 mg Kg-1 when no B was applied, it was 0.3 mg Kg-1 at 4.4 Kg B ha-1 application. It is concluded that soil B application tends to improve the yield and quality of cauliflower cultivated at the upland maize based system in mid-hill areas of Nepal.","PeriodicalId":89696,"journal":{"name":"Journal of the Institute of Agriculture and Animal Science","volume":"39 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89785543","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 life cycle of coffee white stem borer was studied in laboratory by inoculation of first instar larvae into coffee branches up to adult emergence. The first instar larvae took 94±3 days to become adult. The monthly observation on the emergence of this borer showed that it was highly weather dependent and has two peak periods of emergence: April - June and September - November. Coffee white stem borer infestation was reduced to 11.11% with the application of treatments like scrubbing of stem and application of red soil mixed with fresh cow dung (1:1) or by stem scrubbing and application of Bordeaux paste on it followed by root zone application of Metarrhizium anisopliae (22.22%) or Beauveria bassiana (22.22%), or spraying of 10% lime (22.22%). Proper and timely management practices during cultivation and selection of borer resistant genotype seem beneficial for the coffee growers. Further, application of borer management practices based on abundance models are recommended to minimize the pest infestation.","PeriodicalId":89696,"journal":{"name":"Journal of the Institute of Agriculture and Animal Science","volume":"62 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89056892","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}

Relevant secondary data from different sources were used for the study. Study shows youth unemployment rate is decreasing. About 66% of the total employment is dependent on agricultural sector which is in the decreasing rate as the slow transformation of agriculture- based economy to modern economy. Around 56% of household receives the remittance, inflow of remittance is in increasing trend to fiscal year 2016/2017 but it shrinks in 2017/2018. Bagmati and Karnali province had higher and lower number of working age population respectively.Similarly, greater unemployment rate found in Province 2. In first eight months of the Fiscal year 2017/18, 12,622 people have been provided the orientation training and 658 people have been provided skill-based training through youth and Small Entrepreneurship Self-employment Programs. Government launched Prime Minister Employment Program (PMEP) at national level in fiscal year 2019/2020. Vicious cycle of remittance, poor sectoral growth, low labor productivity, poor policy implementation are key factors for unemployment. There is urgent need for domestic job to absorb labour force. Youth and marginalized community targeted program, skill development and enhancement program should be emphasized from government level.","PeriodicalId":89696,"journal":{"name":"Journal of the Institute of Agriculture and Animal Science","volume":"180 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80682271","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 treatments included were the combinations of three mulching materials, (a) plastic mulch, (b) straw mulch, and (c) no mulching; and four nitrogen levels (0, 50, 100, and 150 kg ha-1) arranged in a split-plot design with four replications. Data on growth, yield attributes, and yield were taken and analyzed by using R Studio. The higher (p<0.05) heat use efficiency was recorded under plastic mulch and the higher levels of nitrogen application. The number of kernels per cob and thousand kernel weight were higher (p<0.05) in mulch treatments and higher nitrogen levels. Both the barrenness and sterility percentage were higher (p<0.05) for the 0 kg N ha-1 and reduced (p<0.05) by the nitrogen application of ≥100 kg ha-1. Increased tasseling-silking interval increased (p<0.05) the sterility and grain filling duration and increased (p<0.05) the grain yield. Due to the better yield attributes, the grain yield of mulch applied treatments and application of ≥100 kg N ha-1 were higher (p<0.05) than the no mulch and ≤50 kg N ha-1, respectively. The yield was hampered more by barrenness than by sterility. The effect of nitrogen levels on grain yield followed the quadratic relationship; 104 kg and 129-130 kg N ha-1, respectively for no mulch and mulching treatments which are estimated as economic levels of nitrogen fertilizers for open-pollinated spring maize under the central inner Terai environment.","PeriodicalId":89696,"journal":{"name":"Journal of the Institute of Agriculture and Animal Science","volume":"39 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84246739","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 laid out in a randomized complete block design (RCBD) with nine treatments and three replications. The treatments consist of three different sources of nitrogen (Biomal, vermicompost and chemical fertilizers) having three different levels (80, 120 and 160 kg N/ha) from each source. Plant height, number of leaves/plant, total biomass/plant, total dry matter/plant and leaf area index were measured at 75 days after planting (DAP). Similarly, days to tuber initiation, number of tubers/plant, number of tubers/plot, tuber yield/plot and total tuber yield (mt/ha) were recorded. Cumulative physiological weight loss, greening percentage and sprouting percentage were observed during storage. B/C ratio of all the treatments were computed and compared. Experimental results revealed highest plant height (42.8cm), no. of leaves (145), biomass (98.9 gm/plant), dry matter (9.17 gm/plant) and leaf area index (3068.5 per plant) were recorded when 160kg N/ha applied through Biomal. The highest tuber yield (47.8 mt/ha) and B/C ratio (2.41) were obtained from Biomal at 160 kg N/ha. From this study, 160 kg N/ha from Biomal is recommended for higher productivity and economic returns for ware potato production from TPS hybrid (HPS II/67) under Meghauli, Chitwan, Nepal.

Primary data were collected by the use of pretested interview questionnaire from 120 respondents selected at random to represent farmers of mandarin zone area. Data were processed and analyzed by using descriptive and inferential statistics through Ms-excel and SPSS. Chi-square tested the significant difference between independent and dependent variables. The analysis showed that majority of the respondents were middle age group, male, literate, had medium family size and medium level of income. Majority of them were affiliated to the farmers’ groups but lacked training. Majority of the respondents had medium level adoption of improved orchard management practices of mandarin. Among the socio-demographic parameters observed, significant relationship was found in case of age, education, membership in farmer’s group/organization, training and extension contact. Lack of knowledge and irrigation facility, insect-pest and disease problem and climatic uncertainty are the major problems in mandarin production.
