Abstract:
A field experiment was conducted in a naturally ventilated polyhouse and
open field in the research plot of the Department of Irrigation and Drainage
Engineering, KCAET, Tavanur during October 2017- January 2018 to study the
nutrient use efficiency of Okra in soil and soilless media using fertigation. The
experiment was done with 12 treatments consisting of combination of 3
fertigation level in soil and soilless media under polyhouse and open field with 3
replications. The maximum yield was observed for the treatment having 100%
fertigation in soil outside the polyhouse (T 5 ). The minimum yield was observed
for the treatment having 120% fertigation in soilless media outside the polyhouse.
It was observed that the biometric parameters do not significantly differ for
different fertigation levels. The maximum nutrient efficiency was observed for
treatment has 80% fertigation level in soil outside the polyhouse (T 4 ) and
minimum for treatment having 120% fertilizer recommendation in soilless outside
polyhouse. By statistical analysis, it was observed that, the growing environment
and the media in which the crop grown influences its yield.
