Conservation agriculture and weed management effects on weed community and crop productivity of a rice-maize rotation.

In recent years, an increase in weed infestation, which is adversely affecting crop growth and productivity has been a major challenge facing the farmers of South Asia. The adoption of a permanent bed in combination with residue retention-based crop management practices may reduce weed abundance and increase crop productivity. In a two-year field study, we evaluated the responses of different organic weed management practices with contrasting tillage and residue (R) management strategies to weed dynamics and crop productivity under rice-maize rotation.

Syphilis and COVID-19: Changing trends.

Background: There is a change in the pattern and prevalence of acquired syphilis due to better awareness, surveillance, laboratory diagnosis, and treatment in India in recent years. However, restrictive measures for COVID-19 may produce different effects on incidence.

Aims And Objectives: We aimed to study the changing trend of acquired syphilis in relation to COVID-19 outbreak in a tertiary care hospital in North India.

Role of Entorhinal and Parahippocampal in Diagnosis of Alzheimer's Disease from Resting State EEG.

Alzheimer's disease (AD) poses a significant public health problem. An early diagnosis during the initial development stage of this neurodegenerative brain disorder is a requisite. Initial symptoms of AD involve dysfunctioning in brain memory which later progresses toward language, comprehension, reasoning, and social behavior.

Impact of Different Fertilizer Sources under Supplemental Irrigation and Rainfed Conditions on Eco-Physiological Responses and Yield Characteristics of Dragon's Head ().

The effects of the irrigation regime and different fertilizer sources on the eco-physiological responses and yield characteristics of dragon's head were explored in a factorial experiment based on a randomized complete block design with 12 treatments and 3 replications in the 2019 growing season. The treatments included six different fertilizer sources (animal manure, vermicompost, poultry manure, biofertilizer, chemical fertilizer, and control) and two irrigation regimes (rainfed and supplemental irrigation). The results indicated the positive effects of supplementary irrigation and the application of vermicompost, poultry manure, and animal manure by increasing the absorption of nutrients (phosphorus and potassium) and improving relative water contents, chlorophyll and carotenoid contents, and the fixed oil percentage of dragon's head.
