Research Methods and How to Conduct a Research

Materials and Methods

The investigations were carried out to evaluate the 'Yield performance of wheat under various management practices' conducted at student's farm, department of Agronomy, Sindh Agriculture university, Tandojam during 1982-83.

The detail of treatments under study were as under:

I. Herbicide:             Two

           H1          =    Treated with Buctril -M

           H2          =    Untreated.

II. Irrigation Levels:  Two

           I1           =     Three Irrigation.

           I2           =      Four Irrigation.

III. Fertilizer Levels:  Three

           F1           =     100-50      Kg   NP/ha

           F2           =     150-75      Kg   NP/ha

           F3           =     200-100      Kg   NP/ha

The experiment was laid out in split plot design with replications. The ultimate plot size was 9X6 meters. The layout of experiment is given as appendix I.

Land Preparation and Method of Sowing

The experimental plot was prepared in the month of late October 1982. Normal field operations were carried out as per recommendation of agriculture department. Soaking dose was given on 7th November 1982. Sowing was done by single Coulter hand drill on 11.11.1982. Full dose of phosphorus and half dose of N was applied at the time of sowing and remaining half dose N was applied at the time of first irrigation. irrigation water was given to experiment as per treatments and herbicide (Buctril-M) was also applied as per the treatments after three days of first irrigation.

The crop was harvested on 30.03.1983. Before harvesting the ticketed plants from each plot were pulled out and labelled for single plant study. After drying the wheat was threshed and grains were weighted separately. 

Observations Recorded    

1.  Plant height

2.  Number of tillers per square meter.

3.  Length of ear-head.

4.  Number of spike-lets per ear-head.

5.  Number of grains per ear-head

6.  Weight of grains of selected ten plants.

7.  Biological weight of plants per meter square.

8.  Weight of grains per square meter.

9.  1000 grain weight per square meter.

10. Yield per plot/hectare.

 

Analysis of Variance

Statistical method appropriate to split plot design was used to analysis the data. The usual analysis of variance for comprising various treatments and treatment combinations were carried out and the analysis of variance of different observations are given in the appendices.
