Abstract:
The study entitled "Analysis of. Rice Crop Yield Grown Under the
Treatments of Nitrogen and Water" was undertaken during Kharif 2001 at the Demonstration Farm of WRDTC, IIT Roorkee. The experiment consisted of 3 irrigation levels, 2 levels of nitrogen treatments and 3 replications.
Observations were recorded at 20 days interval regarding growth and development, i.e., plant height, tiller number, leaf area index, dry, weight, rooting depth, leaf length, leaf width and leaf number in each treatment. Weather parameters were recorded daily from agro meteorological lab of WRDTC, at 9.00 AM in forenoon and 2.30 PM in the afternoon such as DBT & WBT, wind speed, minimum and maximum temperature, soil temperature, evaporation, rainfall and sunshine hours. Daily calculation of evapotranspiration (ET0) from the data of transplanting.
Six lysimeters installed at demonstration farm were used for reading daily crop evapotranspiration (ETC). Water level was maintained in lysimeters daily by adding or removing the water to the level of pointer fixed in the lysimeters....
