Abstract
Estimation of rainfall is generally carried out corresponding to a
single period independently without considering the inter-dependence of the
rainfall received in the different periods. A multivariate approach, which
applies cluster analysis, has been suggested for this purpose. The study also
proposes an approach for isolating the effect of different factors affecting the
crop yields as well as studying its association with the information obtained
from the multivariate estimates. The study was confined to the four districts
of Telangana region, forty three years of crop yield-rainfall data(1960-61 to
2002-03)was used in the present study. It was observed that the multivariate
approach efficiently identified the representative rainfall patterns in the four
districts. Further, these patterns also exhibited to a certain extent association
With the clusters of crop yield, which described the impact of different
factors on crop, yields.
