Response of Grass to Chemical Fertilizers Research Paper

Response of Grass to Chemical Fertilizers - Research Paper Example Do not put any fertilizer in pot E-1, 2 & 3 (Control). 6. Place all pots in lighted area 7. Water plants daily at noon or arrange automatic drip irrigation system 8. Measure plants at noon at 10 days intervals with ruler and record in notebook in units of millimeters for 50 days 9. Uproot 5 plants randomly from each pot at 5 days interval and record the oven dry weight for 50 days. Observations /Results: The data were analyzed by using statistical method for test of significance at 1% and / or 5% level of significance. In this experiment there are 5 treatments i.e 15-15-15, 46-0-0, 0-16-0, 0-0-60 and no fertilizer (Control) were replicated thrice resulting in 15 experimental units (pots).The design required is Completely Randomized Design (CRD).

Then the F value in ANOVA table is compared with the table value and then the significance is measured at 1% and / or 5% level. Finally the plant heights for all dates of observation are arranged in a single table for result discussion and conclusion.

The data were analyzed by using statistical method for test of significance at 1% and / or 5% level of significance. In this experiment there are 5 treatments i.e 15-15-15, 46-0-0, 0-16-0, 0-0-60 and no fertilizer (Control) were replicated thrice resulting in 15 experimental units (pots).The design required is Completely Randomized Design (CRD). Like wise all data for next dates recording grass height i.e. at 20DAS, 30DAS, 40DAS and finally 50DAS were analyzed by using CRD. Then the F value in ANOVA table is compared with the table value and then the significance is measured at 1% and / or 5% level. If the mean difference between 5 treatments was more than the CD then the application of chemical fertilizer did not have any significant effect on the grass height and they were at par with each other. If the difference exceeds the CD value then the treatments were different from each other or in other words the application of fertilizer was having significant effect on the grass height and dry matter accumulation. My original hypothesis was that application of chemical fertilizer (15-15-15) to soil would be better over the control. My results showed that application of chemical fertilizer was having significant effect on the grass height and dry matter accumulation over the same period of growth.
