MICRO IRRIGATION PRACTICES IN TOMATO - Management, Performance, and Applications of Micro Irrigation Systems - page 188

T 7 = 60% IR through drip irrigation with black LDPE mulch (0.6 VD+M); and
T8 = 100% IR by furrow irrigation with black LDPE mulch (V+M).
In furrow treatment, irrigation was applied to each furrow. Furrows were laid at
0.25% bed slope. The furrows had dyes at the downstream end to prevent runoff. Poly-
thene sheets were inserted to a depth of 60 cm in the inner side of the dykes of each
plot to prevent lateral seepage. In case of drip irrigation, there were two crop rows per
each lateral and one dripper per plant. Figures 2 and 3 show the actual layout of drip
in tomato crop in the fi eld.
