In-Depth Information
inline drippers were fi xed at spacing of 50 cm. The number of laterals installed was
based on the number of rows of crops grown. The discharge rate of single dripper is
4 L per hour.
Sub main and laterals were closed at the end with the end cap. Laterals were placed
for each row per plot and in between two rows per plot, with 11 emitters in each lateral
at a discharge rate of 4 L per hour. Irrigation scheduling at 65, 75, and 85% of irriga-
tion requirement for each day was commenced after the transplanting.
12.2.2 EXPERIMENTAL DESIGN
The experiment was laid out with seven treatments, combination consisting of three
irrigation levels and two drip system layouts. The experiment was laid out in random-
ized block design having seven treatment combinations and was replicated thrice. The
treatment details are shown in Table 1.
