Rice and Water
TL;DR: The Comprehensive Assessment of Water Management in Agriculture (CA) seeks answers to the question of how freshwater resources can be developed and managed to feed the world's population and reduce poverty, while at the same time promoting environmental security.
Book ChapterDOI
Halting the groundwater decline in north-west India--which crop technologies will be winners?
Elizabeth Humphreys,Surinder S. Kukal,Evan W. Christen,G. S. Hira,Balwinder Singh,Sudhir Yadav,Ramesh Kumar Sharma +6 more
TL;DR: In this paper, the authors investigated the impact of different technologies on the productivity of the rice-wheat (RW) system in north-west India and found that the best technologies for achieving this are delaying rice transplanting and short duration rice varieties.
Journal ArticleDOI
Performance of CERES-Rice and CERES-Wheat models in rice–wheat systems: A review
TL;DR: In this article, the performance of the CERES-Rice and CE-Wheat models was evaluated using simulated and observed data on anthesis and maturity dates, in-season LAI and growth, final grain yield and its components, and soil water and N balances from published studies across Asia and Australia, and then by computing the statistical parameters for the major characters.
Journal ArticleDOI
The Happy Seeder enables direct drilling of wheat into rice stubble
HS Sidhu,Manpreet-Singh,Elizabeth Humphreys,Elizabeth Humphreys,Yadvinder-Singh,Balwinder-Singh,Balwinder-Singh,S. S. Dhillon,John Blackwell,John Blackwell,Bector,Malkeet-Singh,Sarbjeet-Singh +12 more
TL;DR: The Happy Seeder as discussed by the authors combines the stubble mulching and seed drilling functions in the one machine, which reduces air pollution and loss of nutrients and organic carbon due to burning, at the same time as maintaining or increasing yield.
Journal ArticleDOI
Effect of water management on dry seeded and puddled transplanted rice: Part 2: Water balance and water productivity
TL;DR: In this paper, a field experiment was conducted to compare water balance components and water productivity of dry seeded rice (DSR) and puddled transplanted rice (PTR) with four irrigation schedules based on soil water tension (SWT) ranging from saturation (daily irrigation) to alternate wetting drying (AWD) with irrigation thresholds of 20, 40 and 70kPa at 18-20 cm soil depth.
