Chilli (Capsicum annum L) under fertigation’ was conducted at Water management
research unit (WMRU) Vellanikkara, a sub centre of agronomic research station
(ARS) Chalakudy, during March 15 2017 to August 15 2017. The experiment was
conducted in two growing conditions of open field and poly house with four
ferigation levels and having one control with conventional method of irrigation
and fertilizer application with 100% NPK as per POP.
From this study result revealed that under Kerala condition during
February 2017 to August 2017 better performance of growth parameters and yield
contributing characters resulted in higher yield under open field condition with
conventional method of irrigation and fertilizer application than open field and
poly house with fertigation.
The study revealed that the growth and yield of chilli was better for plants
receiving higher quantity of water. The quantity of water fixed was 100% PE for
the fertigation. It was not sufficient to meet the growth requirement and to meet
the evaporation demand of crop under poly house condition. Water productivity
and nutrient use efficiency under conventional method of irrigation and fertilizer
application followed by open field with fertigation was found higher compared to
poly house plants receiving fertigation. This was due to the higher yield under
open field condition. Result of the study indicated that microclimatic condition
prevailed during the growth period had significant influence on the growth and
yield parameter of chilli.
The yield, water productivity and nutrient use efficiency were not affected
by the levels of fertigation. Through fertigation, providing lesser nutrients that is
application of 75% NPK with 25% as basal is enough for the maximum
production.
So
there
will
be
a
reduction
of
25%
of
nutrients.
Net return and Benefit cost ratio were found to be much higher under
conventional method of fertilizer application compared to open field and poly
house with fertigation.
