The rise of water table situation, which causes waterlogging in agricultural field, can be
controlled with biological drainage in addition to usual engineering drainage measures. The
process uses the transpiration properties of trees. The biodrainage species, also known as
“phreatophytes”, is able to draw water directly from the groundwater table or from the capillary
fringe above it and eventually transpiring it to atmosphere. This causes decline in water table
beneath the vegetation bringing waterlogged field to cultivable condition. Under such scenario
in post monsoon season watermelon was cultivated as intercrop in a biodrained field under
Casuarina equisetifolia plantation. Comparative photosynthesis performance of watermelon in
field with and without Casuarina plantation was evaluated. The objective was to physiologically
evaluate productivity of intercrops like watermelon under biodrainage vegetation and
understanding the tree-intercrop interaction in reclaimed field. The Casuarina plantation on an
average caused 21-34% reduction in incident of photosynthetically active radiation (PAR) over
watermelon crop in comparison to control. In spite of reduced PAR, photosynthesis rate in two
cultivars ‘Mokasa’, Arka Manik and local ‘Sugar baby’ was higher (24.63, 20.36 and 19.43 m mol
m-2 s-1) than control (21.80, 19.60 and 18.93 m mol m-2 s-1, respectively). The excess soil water
in root zone in control field caused reduction in photosynthesis, stomatal conductance as well
as yield, in all the three cultivars. Inside biodrainage vegetation the photosynthesis, stomatal
conductance and yield of all the cultivars were better than control. However, cultivars Mokassa
and Arka Manik were found better than local ‘Sugar baby’ both in photosynthetic performance
as well as yield and therefore, were more suitable cultivar as an intercrop inside Casuarina
biodrainage vegetation.
