The effects of nitrogen (N) application (32, 72 and 112 kg N ha-1 in 2000, and 32, 92 and 152 kg N ha-1 in 2001) and water-saving irrigation and their interaction on grain yield and yield components o...
Water Saving by Shallow Intermittent Irrigation and Growth of Rice
Rice growth Water management Water productivity Water saving ratio
font style='font-size:12px;'>
2009/7/24
To reduce water requirement and improve water productivity (the grain yield per unit volume of water irrigated) by water-saving irrigation techniques, we examined the effects of very shallow intermitt...
Water Saving in Rice-Wheat Systems
Evaporation Deep drainage Irrigation Percolation Water use efficiency
font style='font-size:12px;'>
2009/7/24
Water shortage is a major constraint to sustaining and increasing the productivity of rice-wheat systems. Saving water can be elusive in that reducing seepage, percolation and runoff losses from field...
