Conclusions
(1) In denser spacing (0.4 m), soil moisture is lower in the
soil deeper layers (> 0.6 cm) compared to larger spacing.
(2) Cotton plant grown in conventional spacing (1.0 m)
has lower water use efficiency for seed cotton yield
compared to the denser system (0.7 and 0.4 m).
(3) Higher cotton plant water use efficiency can be
obtained in intermediate spacing, 0.6 m.
