Rice growth and nitrogen uptake as influenced by water management

Sariam O., . and Mohd. Khanif Y., . and Zahrah T., . (2002) Rice growth and nitrogen uptake as influenced by water management. [Proceedings Paper]

Rice Oryza sativa L. is a unique crop as it can adapt to a wide range of water condition and can be grown in moisture ranging from flooded to upland conditions. Rice can be grown under non flooded condition and can even be irrigated like any other upland cereals to obtain good yield. However farmers prefer to maintain a relatively high depth of water in order to control weeds and reduce the frequency of irrigation. This leads to a high amount of surface runoff seepage and percolation. But water is now becoming increasingly scarce and is expected to continue declining in the future. This is mainly due to the increasing demand for available water from urban and industrial sectors which is likely to receive priority over irrigation. Thus it may necessitate the adoption of rice production practices that reduce water inputs. A greenhouse study was conducted to evaluate water management practices on growth yield and nitrogen uptake of rice.

Abstract

Rice Oryza sativa L. is a unique crop as it can adapt to a wide range of water condition and can be grown in moisture ranging from flooded to upland conditions. Rice can be grown under non flooded condition and can even be irrigated like any other upland cereals to obtain good yield. However farmers prefer to maintain a relatively high depth of water in order to control weeds and reduce the frequency of irrigation. This leads to a high amount of surface runoff seepage and percolation. But water is now becoming increasingly scarce and is expected to continue declining in the future. This is mainly due to the increasing demand for available water from urban and industrial sectors which is likely to receive priority over irrigation. Thus it may necessitate the adoption of rice production practices that reduce water inputs. A greenhouse study was conducted to evaluate water management practices on growth yield and nitrogen uptake of rice.
