Simulation of salt and water movement and estimation of water productivity of rice crop irrigated with saline water

The HYDRUS-ID model was experimentally tested for water balance and salt build up in soil under rice crop irrigated with different salinity water (ECiw) of 0.4, 2, 4, 6, 8 and 10xa0dSxa0m−1 in micro-lysimeters filled with sandy loam soil. Differences of means between measured (M) and HYDRUS-1D predicted (P) values of bottom flux (Qo) and leachate EC as tested by paired t test were not found significant at Pxa0=xa00.05 and a close agreement between RMSE values showed the applicability of the HYDRUS-1D to simulate percolation and salt concentration in the micro-lysimeters under rice crop. Potential ET values of rice as obtained from CROPWAT matched well with model predicted and measured one at all ECiw treatments. The model predicted root water uptake varied from 66.1 to 652.7xa0mm and the maximum daily salt concentration in the root zone was 0.46, 2.3, 4.5, 6.7, 8.4 and 10.2xa0mexa0cm−3 in 0.4, 2, 4, 6, 8 and 10xa0dSxa0m−1 ECiw treatments, respectively.

reduced to one-fifth when percolation was included in the productivity determination. Similarly, the water productivity in respect of total dry matter production (TDM) was also reduced in different treatments. Therefore, the model predicted values of water balance can be effectively utilized to calculate the water productivity of rice crop.

Rice (Oryza sativa L.) is a member of poaceae family and is relished as staple food by majority of worlds population. In India, rice occupied 45.16 million hectares area with a production of 103.72 million tonnes and average yield 2.7t ha -1 (Anonymous, 2015). Rice is grown in 114 countries across the world on an area about 150 million hectares with annual production of over 525 million tonnes, constituting nearly 11 per cent of the world’s cultivated land. The system of Rice Intensification (SRI) was developed by a Jesuit agriculturist Fr. Henri De Laulanie (1993) and Madagascar colleagues working with him in 1980 and the 1990, and they studied ways to increase the low yields of Madagascar farmers. From Madagascar’s poor soils which yielded usually an average of 2 tonnes per hectare. SRI system coaxed yield of 6, 8 and even 10 tonnes per hectare, while International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 6 Number 10 (2017) pp. 2503-2515 Journal homepage: http://www.ijcmas.com
