Economic Feasibility of Vegetable Production under Polyhouse:A Case Study of Capsicum and Tomato

Polyhouse cultivation of vegetables is emerging as a specialized production technology to overcome biotic and abiotic stresses and to break the seasonal barrier to production. It also ensures round the year production of highvalue vegetables, like capsicum, especially, during off-season. Cost is the major issue in sustaining this technology. The present study examined the economic viability of production of capsicum and tomato in a naturally ventilated polyhouse of medium cost category with drip irrigation system. Data were generated by cost accounting method for estimating the feasibility of production and was analyzed by using project evaluation methods, like Pay Back Period (PBP), Benefit Cost Ratio (BCR), Net Present Value (NPV) and Internal Rate of Return (IRR). Cultivation of capsicum in a polyhouse was found to be highly feasible as reflected in higher values of NPV (Rs.3,23,145/500 m2), BCR (1.80) and IRR (53.7%) with payback period of less than two years. Breakeven price for capsicum production in a polyhouse (Rs.11.80/kg) was lesser than average wholesale price. Production of tomato in a polyhouse was found not feasible, as the breakeven price was more than the average market price and all the project appraisal parameters indicated that it was not feasible. Only at about 48% premium price over the prevailing market price or reduction of cost of polyhouse structure by 60% from Rs.400 to Rs.160 /m2, could make the tomato production viable in a poly house

Yield Gap Analysis of Sorghum and Pearl Millet in India Using Simulation Modeling:Global Theme on Agroecosystems Report no. 37

Sorghum and pearl millet are the staple cereals and important source of fodder for animals in the semi-arid and arid parts of India. In the present study, we have: a) characterized the distribution of sorghum and pearl millet in different production zones in India; b) estimated their rainfed potential, achievable and current levels of farmers’ yields; c) quantified the gaps between farmers’ yields and rainfed potential yields; and d) suggested ways to abridge the yield gaps. Using CERES-sorghum and CERES-pearl millet crop growth models and historical weather data, rainfed potential yields and water balance of sorghum (kharif and rabi) and pearl millet were estimated for selected locations in different production zones. Simulated yields were supplemented with the research station yields of rainfed trials and yields of frontline demonstrations, both obtained from the reports of the All India Coordinated Crop Improvement Projects on Sorghum and Pearl Millet. District level yields were considered as farmers’ yields. Based on these data, the yield gaps at various management levels were estimated. The farmers’ average yield was 970 kg ha-1 for kharif sorghum, 590 kg ha-1 for rabi sorghum and 990 kg ha-1 for pearl millet. Simulated rainfed potential yield in different production zones ranged from 3210 to 3410 kg ha-1 for kharif sorghum, 1000 to 1360 kg ha-1 for rabi sorghum and 1430 to 2090 kg ha-1 for pearl millet. Total yield gap (simulated rainfed potential yield - farmers’ yield) in production zones ranged from 2130 to 2560 kg ha-1 for kharif sorghum, 280 to 830 kg ha-1 for rabi sorghum and 680 to 1040 kg ha-1 for pearl millet. This indicates that productivity of kharif sorghum can be increased 3.0 to 4.0 times, rabi sorghum 1.4 to 2.7 times and pearl millet 1.8 to 2.3 times from their current levels of productivity. To abridge the yield gaps of sorghum and pearl millet, integrated watershed-based approach encompassing harvesting of excess rainfall for supplemental irrigation, growing high yielding crop cultivars, integrated nutrient management and integrated pest and disease management would be required. Value addition of products and their multiple uses are necessary to make them more remunerative for the farmers

Expert consensus on the management of acne in India

Acne, a common cutaneous disorder, is estimated to affect a significant proportion of the population at some point in their lifetime. It is one of the most common presentations reported in dermatological consultations in India. Treatment options for acne include topical, oral and procedural therapies. Patients with mild acne can be treated with topical therapies; however, those with moderate to severe acne require systemic cure. Oral antibiotic treatment, hormonal therapies and isotretinoin are the mainstay systemic therapies for acne. Additionally, procedural therapeutic modalities in dermatology include chemical peels, laser therapy, micro needling techniques, to name a few. Scientific advances are continually improving knowledge of acne and contributing to refinement of treatment options. Hence, it is vital for clinicians to regularly update their clinical practice patterns to reflect current standard. An experts’ panel discussion involving dermatologists from across India was conducted, to outline a practical approach for the management of acne. The present consensus document focuses on the assessment of acne, use of topical treatments, role of systemic therapy and procedures in treating acne and post-inflammatory hyperpigmentation. It also emphasizes the role of patient education and counselling on prophylactic and treatment strategies in acne management

Clinical characteristics, risk factors and outcomes in patients with severe COVID-19 registered in the International Severe Acute Respiratory and Emerging Infection Consortium WHO clinical characterisation protocol: a prospective, multinational, multicentre, observational study

Respiratory infections and tuberculosisInfecciones respiratorias y tuberculosisInfeccions respiratòries i tuberculosiDue to the large number of patients with severe coronavirus disease 2019 (COVID-19), many were treated outside the traditional walls of the intensive care unit (ICU), and in many cases, by personnel who were not trained in critical care. The clinical characteristics and the relative impact of caring for severe COVID-19 patients outside the ICU is unknown. This was a multinational, multicentre, prospective cohort study embedded in the International Severe Acute Respiratory and Emerging Infection Consortium World Health Organization COVID-19 platform. Severe COVID-19 patients were identified as those admitted to an ICU and/or those treated with one of the following treatments: invasive or noninvasive mechanical ventilation, high-flow nasal cannula, inotropes or vasopressors. A logistic generalised additive model was used to compare clinical outcomes among patients admitted or not to the ICU. A total of 40 440 patients from 43 countries and six continents were included in this analysis. Severe COVID-19 patients were frequently male (62.9%), older adults (median (interquartile range (IQR), 67 (55–78) years), and with at least one comorbidity (63.2%). The overall median (IQR) length of hospital stay was 10 (5–19) days and was longer in patients admitted to an ICU than in those who were cared for outside the ICU (12 (6–23) days versus 8 (4–15) days, p<0.0001). The 28-day fatality ratio was lower in ICU-admitted patients (30.7% (5797 out of 18 831) versus 39.0% (7532 out of 19 295), p<0.0001). Patients admitted to an ICU had a significantly lower probability of death than those who were not (adjusted OR 0.70, 95% CI 0.65–0.75; p<0.0001). Patients with severe COVID-19 admitted to an ICU had significantly lower 28-day fatality ratio than those cared for outside an ICU.This work was supported by the UK Foreign, Commonwealth and Development Office and Wellcome (215091/Z/18/Z), the Bill and Melinda Gates Foundation (OPP1209135), Canadian Institutes of Health Research Coronavirus Rapid Research Funding Opportunity OV2170359, grants from Rapid European COVID-19 Emergency Response Research (Horizon 2020 project 101003589), the European Clinical Research Alliance on Infectious Diseases (965313), The Imperial National Institute for Health Research (NIHR) Biomedical Research Centre, and The Cambridge NIHR Biomedical Research Centre; and endorsed by the Irish Critical Care Clinical Trials Group, co-ordinated in Ireland by the Irish Critical Care Clinical Trials Network at University College Dublin and funded by the Health Research Board of Ireland (CTN-2014-12).

Characterizing the normal proteome of human ciliary body

BACKGROUND: The ciliary body is the circumferential muscular tissue located just behind the iris in the anterior chamber of the eye. It plays a pivotal role in the production of aqueous humor, maintenance of the lens zonules and accommodation by changing the shape of the crystalline lens. The ciliary body is the major target of drugs against glaucoma as its inhibition leads to a drop in intraocular pressure. A molecular study of the ciliary body could provide a better understanding about the pathophysiological processes that occur in glaucoma. Thus far, no large-scale proteomic investigation has been reported for the human ciliary body. RESULTS: In this study, we have carried out an in-depth LC-MS/MS-based proteomic analysis of normal human ciliary body and have identified 2,815 proteins. We identified a number of proteins that were previously not described in the ciliary body including importin 5 (IPO5), atlastin-2 (ATL2), B-cell receptor associated protein 29 (BCAP29), basigin (BSG), calpain-1 (CAPN1), copine 6 (CPNE6), fibulin 1 (FBLN1) and galectin 1 (LGALS1). We compared the plasma proteome with the ciliary body proteome and found that the large majority of proteins in the ciliary body were also detectable in the plasma while 896 proteins were unique to the ciliary body. We also classified proteins using pathway enrichment analysis and found most of proteins associated with ubiquitin pathway, EIF2 signaling, glycolysis and gluconeogenesis. CONCLUSIONS: More than 95% of the identified proteins have not been previously described in the ciliary body proteome. This is the largest catalogue of proteins reported thus far in the ciliary body that should provide new insights into our understanding of the factors involved in maintaining the secretion of aqueous humor. The identification of these proteins will aid in understanding various eye diseases of the anterior segment such as glaucoma and presbyopia

Fusarium oxysporum f. sp. lycopersici causal agent of vascular wilt disease of tomato: Biology to diversity– A review

Tomato (Lycopersicon esculentum) is one of the widely grown vegetables worldwide. Fusarium oxysporum f. sp. lycopersici (FOL) is the significant contributory pathogen of tomato vascular wilt. The initial symptoms of the disease appear in the lower leaves gradually, trail by wilting of the plants. It has been reported that FOL penetrates the tomato plant, colonizing and leaving the vascular tissue dark brown, and this discoloration extends to the apex, leading to the plants wilting, collapsing and dying. Therefore, it has been widely accepted that wilting caused by this fungus is the result of a combination of various physiological activities, including the accumulation of fungal mycelia in and around xylem, mycotoxin production, inactivation of host defense, and the production of tyloses; however, wilting symptoms are variable. Therefore, the selection of molecular markers may be a more effective means of screening tomato races. Several studies on the detection of FOL have been carried out and have suggested the potency of the technique for diagnosing FOL. This review focuses on biology and variability of FOL, understanding and presenting a holistic picture of the vascular wilt disease of tomato in relation to disease model, biology, virulence. We conclude that genomic and proteomic approachesare greater tools for identification of informative candidates involved in pathogenicity, which can be considered as one of the approaches in managing the disease

A Mixed-Method Study to Determine the Benefits of Periconceptional Folic Acid Supplementation and Effects of Folic Acid Deficiency in Mothers on Birth Outcomes.

BACKGROUND: Evidence from high income countries shows mothers who are supplemented with folic acid in their periconceptional period and early pregnancy have significantly reduced adverse outcomes like birth defects. However, in India there is a paucity of data on association of birth defects and folic acid supplementation. We identified a few important questions to be answered using separate scientific methods and then planned to triangulate the information. OBJECTIVE: In this paper, we describe the protocol of our study that aims to determine the association of folic acid and pregnancy outcomes like neural tube defects (NTDs) and orofacial clefts (OFCs). We decided to fill the gaps in knowledge from India to determine public health consequences of folic acid deficiency and factors influencing dietary and periconceptional consumption of folic acid. METHODS: The proposed study will be carried out in five stages and will examine the questions related to folic acid deficiency across selected locations in South and North India. The study will be carried out over a period of 4 years through the hierarchical evidence-based approach. At first a systematic review was conducted to pool the current birth prevalence of NTDs and orofacial clefts OFCs in India. To investigate the population prevalence, we plan to use the key informant method to determine prevalence of NTDs and OFCs. To determine the normal serum estimates of folic acid, iron, and vitamin B12 among Indian women (15-35 years), we will conduct a population-based, cross-sectional study. We will further strengthen the evidence of association between OFCs and folic acid by conducting a hospital-based, case-control study across three locations of India. Lastly, using qualitative methods we will understand community and health workers perspective on factors that decide the intake of folic acid supplements. RESULTS: This study will provide evidence on the community prevalence of birth defects and prevalence folic acid and vitamin B12 deficiency in the community. The case-control study will help understand the association of folic acid deficiency with OFCs. CONCLUSIONS: The results from this study are intended to strengthen the evidence base in childhood disability for planning and policy initiatives
