Abstract
An attempt was made to develop a scale to measure perception of seed
growers towards vegetable seed production. The method of summated rating scale
suggested by Likert (1932) [5] and Edwards (1969) [3] were
followed in the development of the scale. A list of 95 items/statements
reflecting the perception about seed production system was prepared through
extensive review of literature and discussion with scientists. The statements
were sent to 135 judges in State Agricultural Universities, Central
Agricultural Universities, Indian Council of Agricultural Research institutions
and Karnataka State Department of Agriculture on three point continuum. In all,
48 judges could respond in time. The relevancy score for each item/statement
was found out by adding the scores on the rating scale for all the 48 judges.
Based on their judgment an aggregate of 33 statements were selected by finding
the relevancy weightage scores (RWS). Statements having an equal or more RWS of
0.75 and mean relevancy score of 2.00 were selected for the item analysis. In
item analysis the selected statements were administered to 30 growers in
non-sample area of Koppal taluk of Karnataka state during 2018-2019. Finally a
total of 21 statements were selected for the study based on ‘t’ values (>
1.75) resulted from the item analysis and were included in the final scale. The
‘r’ value of the scale was found to be 0.9327, which was significant at one per
cent level indicating the high reliability. Hence, the scale developed was
found to be reliable and valid.
