I need some assistance with these assignment. response of grass to chemical fertilizers Thank you in advance for the help!
I need some assistance with these assignment. response of grass to chemical fertilizers Thank you in advance for the help! 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).

NB: DAS- Days after sowing
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.
Finally the plant heights for all dates of observation are arranged in a single table for result discussion and conclusion.
