| dc.description.abstract | During some phenological stages of crop development J
water stress of even short duration would significantly influence
yields. The study of variability of rainfall during the
sensitive stages of the crop is of great importance. It is
because of this sensitiveness of crop to water stress of short
duration that pentad rainfall was chosen for this study.
The object of the present work is to study distribution
and variability of pentad rainfall for 100 stations with records
of more than twenty years, spread allover Kenya in order to use
the knowledge in land use planning for crops.
For that purpose the following statistical properties
of pentad rainfall were examined at each of the 100 stations
,,
and for each of the 73 pentads in a year; mean, standard
deviation coefficient of skewness, coefficient of kurtosis
and the probabilities of pentad rainfall exceeding 25, SO, 75,
100, 125 and 150 per cent of the mean pentad rainfall
It was observed that coefficient of variation, coefficients
of skewness and coefficients of were higher in dry
pentad and in semi-arid and arid regions and lower in wet
regions. Thus it was evident from the results of coefficients
of skewness and,coefficients of kurtosis that pentad rainfall
was different from "normal" | en |
