چکیده
Inappropriate agricultural practices consume more input energy and emit higher greenhouse gases (GHGs) which cause global warming climate change, thereby threatening environmental sustainability. To identify carbon-efficient varieties nutrient management practices, the present study was undertaken during kharif season of 2018 2019 in a split-plot design with three fodder maize (African Tall, J-1006 P-3396) four such as N0: Absolute control, N1: 100% recommended dose fertilizers (RDF), N2: 75% RDF + plant growth promoting rhizobacteria (PGPR) Panchagavya spray N3: 50% 25% farmyard manure (FYM) PGPR spray). Results indicated that variety applying produced significantly dry yield. Among varieties, recorded highest total output (224,123 MJ ha−1), net (211,280 use efficiency (17.64), productivity (0.98 kg MJ−1), profitability (16.64), lowest specific (1.03 ha−1). Regarding management, fetched (229,470 ha−1) (215,482 However, efficiency, productivity, were integrated (N2 N3) over RDF. Concerning carbon estimation, resulted (5479 CE gain (5029 (12.46), sustainability index (11.46), lower footprint per unit yield (CFy) (131.3 CO2-e Mg−1). For application showed (5609 (5112 index, CFy reported Overall, selecting for cultivation could be most productive terms production, energy, approach.

Assessment of impact of climate change on potato and potential adaptation gains in the Indo-Gangetic Plains of India
India is the second largest producer of potato in the world. The Indo-Gangeticplains (IGP) is the main potato growing region accounting for almost 85% of the1.8 Mha under the crop in India where it is grown as an irrigated crop during thewinter season. Since IGP is in sub-tropical plains, duration of the thermally suitablewindow is the main determinant limiting yields. Hence the impact of clima...

Inter-state migration in search of livelihood is an important feature of the Indian economy. The direction of migration is determined by the direction of the inequality. Rural-urban migration is a mechanism of adjustment by an individual or group to development gaps created between the dynamic industrial sector in urban/peri-urban areas and the more inert agricultural sector in rural areas (Gue...
متن کاملSpatial and Temporal Variability of Fog Over the Indo-Gangetic Plains, India
The aim of the paper is to analyze the characteristics of winter fog in terms of its trend and spatial-temporal variability over Indo-Gangetic plains. The study reveals that during last four and half decades (1971-2015), an alarming increasing trend in fog frequency has been observed during the winter months of December and January over the study area. The frequency of fog has increased by 118....
