The Northeastern Region of India is expected to be highly prone to the consequences to climate change because of its geo-ecological fragility, strategic location vis-à-vis the eastern Himalayan landscape and international borders, its trans-boundary river basins and its inherent socioeconomic instabilities. Environmental security and sustainability of the(More)
Along with most widely practiced resources conserving technology zero-tillage wheat after rice, adoption of permanent beds for rice–wheat rotation is also gaining popularity. Since relatively a new approach particularly for dry-seeded rice and permanent beds for wheat, very little information is known about permanent beds on soil properties, nutrient (N)(More)
In the uplands of Eastern Himalayan Region (EHR) of India, dry-seeded rain-fed rice occupies considerable area. However, productivity of rice in this region is very low and is mainly due to frequent occurrence of intermittent soil moisture stress, weed infestation, and poor crop establishment. Keeping this in view, a field experiment on rain-fed(More)
Introduction of irrigated agriculture has turned some basin lands seasonally waterlogged. Seasonally waterlogged soils remain poorly understood particularly in relation to the changes in pedosphere and pedogenic pathways. Present investigation evaluated changes in the pedosphere and its implications in pedogenic pathways of these seasonal waterlogged soils.(More)
The crop and water productivity (WP) of monocropped rice in lowland of north-eastern region of India is low mainly due to cultivation of long duration variety, meagre use of fertilizer and manure, and inefficient water management, which needs to be improved for sustaining food security. Raised and sunken bed (RSB) land configuration (removing the surface(More)
