The vast Indo-Gangetic Plain in South Asia has been home to some of the world's oldest civilizations, whose fortunes ebbed and flowed with time-plausibly driven in part by shifts in the spatiotemporal patterns of the Indian summer monsoon rainfall. We use speleothem oxygen isotope records from North India to reconstruct the monsoon's variability on socially relevant time scales, allowing us to ...

A large part of the Indo-Gangetic plain has marginal soils, which are depleted of nutrients and sandy with low water-holding capacity. Fertilizers and irrigation are applied to obtain regular yield. However, high usage of fertilizers and inappropriate methods of irrigation lead to a degradation of soil microfl ora and loss of soil fertility in the long term. In close collaboration with other pa...

Intensive tillage-based production systems coupled with inefficient fertilizer management practices have led to increased costs, sub-optimal productivity, and significant environmental externalities. Conservation agriculture (CA) is being increasingly advocated as a strategy overcome these issues but precision nutrient under the CA-based maize-wheat system rarely studied. Two year’s (2014–2015 ...

To prevent the transmission of COVID-19, India implemented country-wide restrictions on socio-economic activities. Using satellite observations for pre-monsoon (March–April–May) season, we explore effect extended lockdown, nitrogen dioxide (NO2), formaldehyde (HCHO), sulfur (SO2) and aerosol optical depth (AOD) over India. In this present study evaluate quantify changes in pollutants across six...

Open field burning of rice straw besides causing environmental pollution and human health problems results in loss organic carbon essential nutrients. Urgent solution is required for management an eco-friendly sustainable manner. The aim the present study was to examine efficiency direct return into soil versus biochar generated from straw, compare it with wood derived influencing biological pr...

Direct-seeded rice (DSR) can be a resource-efficient alternative to puddled transplanted (PTR), but weeds and nematodes pose severe challenges. Conservation agriculture (CA)-based DSR may inhibit/influence weeds/nematodes, which further intensified by adopting better weed control. Hence, this experiment was undertaken. Five CA-based practices involving zero tillage, residue retention, brown man...

The present study was carried out at Dr. Rajendra Prasad Central Agricultural University, Samastipur, Bihar during 2021–2023 to focus on examining alterations in SOC pools resulting from conservation agriculture (CA) practices R-W system the eastern IGP, following collection of soil samples a long-term trial that initiated rainy (kharif) season 2006. included eight combinations, namely: convent...
