Influence of weed management practices on direct-seeded rice grown under rainfed and irrigated agroecosystems

Rice seedlings and weeds emerge concurrently in direct-seeded rice (DSR) production systems, while there is no flooding water to inhibit weed germination, emergence and development at crop emergence. Because of this, weeds are considered the biggest living barrier in DSR and significantly reduce yield. The purpose of the research was to devise an approach for management of weeds in the direct-seeded rice crop cultivated under various agroecosystems, while optimizing growth and production utilizing herbicides or herbicidal combinations. The impacts of several weed management techniques were assessed to determine the most efficient and cost-effective approach of managing weeds in DSR at the CoA, JNKVV, Jabalpur (MP) during 2019 rainy season under spilt plot design with 2 main plot treatments viz., rainfed agroecosystem, irrigated agroecosystem and 8 sub-plot treatments, i.e. different herbicide treatments with hand weeding and weedy check. Further growth parameters as well as yield attributes were documented. Conventional statistical techniques were used to evaluate the data. Bispyribac sodium at the dose of 25 g/ha efficiently controlled both narrow and broad leaved weeds under agroecosystems. Highest growth as well as yield parameters were recorded for irrigated agroecosystems compared to rainfed agroecosystems. The treatment with bispyribac sodium at the dose of 25 g/ha produced the greatest values for growth and yield indices as well as the maximum yield (3.68 t/ha), with the exception of manual weeding

Risk of adverse outcomes associated with cardiac sarcoidosis diagnostic schemes

BackgroundMultiple cardiac sarcoidosis (CS) diagnostic schemes have been published.ObjectivesThis study aims to evaluate the association of different CS diagnostic schemes with adverse outcomes. The diagnostic schemes evaluated were 1993, 2006, and 2017 Japanese criteria and the 2014 Heart Rhythm Society criteria.MethodsData were collected from the Cardiac Sarcoidosis Consortium, an international registry of CS patients. Outcome events were any of the following: all-cause mortality, left ventricular assist device placement, heart transplantation, and appropriate implantable cardioverter-defibrillator therapy. Logistic regression analysis evaluated the association of outcomes with each CS diagnostic scheme.ResultsA total of 587 subjects met the following criteria: 1993 Japanese (n = 310, 52.8%), 2006 Japanese (n = 312, 53.2%), 2014 Heart Rhythm Society (n = 480, 81.8%), and 2017 Japanese (n = 112, 19.1%). Patients who met the 1993 criteria were more likely to experience an event than patients who did not (n = 109 of 310, 35.2% vs n = 59 of 277, 21.3%; OR: 2.00; 95% CI: 1.38-2.90; P P P = 0.18 or OR: 1.51; 95% CI: 0.97-2.33; P = 0.067, respectively).ConclusionsCS patients who met the 1993 and the 2006 criteria had higher odds of adverse clinical outcomes. Future research is needed to prospectively evaluate existing diagnostic schemes and develop new risk models for this complex disease.Cardiolog

Weather based crop insurance for risk management in agriculture

In recent years, in many parts of the country, indebtedness, crop failures, unpaid prices and poor returns have resulted in agrarian distress. The government has identified and introduced several programs to address these critical issues viz. crop insurance, lending waivers etc. among them. Crop insurance as a concept for risk management in agriculture has emerged in India since the turn of the twentieth century and government has launched various insurance schemes in last three decades like Comprehensive Crop Insurance Scheme (CCIS), National Agricultural Insurance Scheme (NAIS) and Modified NAIS (MNAIS) etc. Apart from these schemes, several other pilot projects such as Seed Crop Insurance, Farm Income Insurance Scheme and Weather Based Crop Insurance Scheme (WBCIS) were implemented from time to time. At present, two most important schemes are functional i.e. Pradhan Mantri Fasal BimaYojna (PMFBY) and Restructured Weather Based Crop Insurance Scheme (RWBCIS) are in operation. This study focused on the performance of the Restructured Weather based Crop Insurance Scheme (RWBCIS) from historical and analytical perspectives and presents recommendation for future scenarios. RWBCIS scheme having two most important challenges. Firstly, weather data related issues by designing a modern scientific approach to develop high resolution secondary data and secondly, modifying the existing design of RWBCIS Products, based on sound agronomic principles
