average height of tomato plants at 2, 4 and 8 L/hr of
is shown in Fig.4. It can be seen from Figure 4 that
flow rate are 15.3, 14.2 and 14.6 cm respectively and
fruiting of tomato plants has started from third week
average final height of tomato plants were measured
of transplantation for 2L/hr flow rate where as in
36.3, 29.2 and 26.6 cm at flow rate of 2, 4 and 8 L/hr
case of 4 L/hr and 8 L/hr flow rate, fruiting started
respectively. The average increment in the height of

fertigated tomato plants at flow rate of 2, 4 and 8 L/hr
were estimated 137%, 106% and 81.6% respectively.
It can be depicted from Figure 4 that the highest
number of fruit, i.e. 23 tomato fruits, has been

presented in Table 2. It can be seen from Table 2 that
13 numbers of fruits is the highest number of flowers
initial average canopy spread of fertigated tomato
in case of 4 litres/hour and 8 litres/hour. In 13 weeks,
plant at 2L/hr, 4L/hr and 8L/hr were estimated as 8.3,
the total fruiting in the study area was 131, 93 and 79
7.7 and 7.90 cm. Final increment in canopy spread
for flow rate of 2 litres/hour, 4 litres/hour and 8 litres/
of fertigated tomato plant at 2L/hr, 4L/hr and 8L/hr
hour respectively. Thus, the yield is maximum for 2
litres/hour.
