DETECTION OF WATER STRESS AND SALINITY AFFECTING SUMMER SQUASH AND CANTALOUPE USING REMOTE SENSING
Summer squash-Early Yellow Crookneck (Ctrburblta pepo) and Cantaloupe
(Cucumis meld) were grown in the same concrete lysimeters. This study tested the
ability of the two vegetation indices; normalized difference vegetation index and
simple ratio vegetation index on the detection ol‘ water and salinity stress. Also. it
assessed the capability of a new salinity stress index of recognizing salinity stress.
Results showed that the salinity stress index indicated clear separation between the
treatments for most of the data days: h“waver, differences were not statistically
significant. it appears that it was a more appropriate index for cantaloupe than for
summer squash. Both vegetation indices separated between salinity treatments at
most of the data days (60%) for both summer squash and cantaloupe. They clearly
separated between water treatments in about 40-50% of the data days. it appears
that their ability in showing water stress was not as theirs in showing the salinity
stress. Simple ratio stress index was better than the normalized difference
vegetation index in separating between salinity treatments because it gave clear
separation between treatments in about art-rose of the data days. its capability of
showing water stress was not as good as its in assessing salinity stress.
