The fertigation level of 125 per cent of RDF as well as fertigation of recommended dose of N and K at every 2 days interval in equal splits up to 110 days + P as a basal dose to cucumber exhibited significantly maximum vine length & number of branches vine-1 compared to rest of the fertigation levels and schedules under polyhouse condition. Application of 125 per cent of RDF along with fertigation of recommended dose of N and K at every 2 days interval in equal splits up to 110 days + P as a basal dose to cucumber recorded significantly higher fruit length, number of fruits vine-1& average fruit weight than rest of the treatment combinations during first year, second year and on pooled mean. Application of 125 per cent of RDF coupled with fertigation of recommended dose of N and K at every 2 days interval in equal splits up to 110 days + P as a basal dose to cucumber recorded significantly maximum cucumber fruit yield per unit area of polyhouse than rest of the treatment combinations during both the years and on pooled mean. Application of 125 per cent of RDF coupled with fertigation of recommended dose of N and K at every 2 days interval in equal splits up to 110 days + P as a basal dose to cucumber obtained significantly maximum gross monetary returns and B: C ratio under polyhouse condition.
