Course Introduction

This is post-graduate level course in the Department of Agronomy and compulsory for all MSc agronomy students. This course provided basic knowledge about how to conduct the field experiments with accurate layout plant. This course also provides the knowledge to collect the data in filed and analyze the data for presentation. This course will introduce the method of collecting data and analyze the data and  develop a skill to presentation in tabulated or graphical form. This course is very helpful for the students to write their thesis especially results and discussion.

Objective:To plan the experiments according to different design and layout therein the field and to collect the data, analysis it and interpretation.

 

Theory

Methods of scientific inquiry; general types of experiments; Principles of experimental design; Planning, layout and conducting field experiments; Recording research observations; Transformation of data ; Planned F test; Data processing, analyses and its statistical interpretation; Means separation; Probability; F and t distributions; Regression and correlation; Research results reporting.

 

Practical

Statistical calculations based on sample data; Exercise in the layout of experiments; Transformation of Experimental data; Preparation of analysis of variance table; Use of different tests of significance; Factorial experiments and their uses in scientific research; Reporting results of experiment; calculation of linear regression and correlations; Use of statistical packages for data.

Outcomes;

The main aim of the course is to train the students to design and make layout of the field crop experiments keeping in view different experimental designs to collect the data on a scientific basis. They may be able to analyze and interpret the collected data. On completion of course, the students will have the ability to plan experiments according to suitable design and layout these in the field. They may have scientific approach to collect, analyze and interpret the data.
