Abstract
A field experiment was conducted during winter 2014 and 2015 in Jagatsinghpur district of Odisha to study the effect of different fertigation levels and emitter types on productivity, input use efficiency and profitability of tomato (Solanum lycopersicum L.). The three levels fertigation, i.e. recommended dose (125-75-100 kg N-P2O5-K2O/ha) of fertiliser (RDF), 80% RDF and 60% RDF and four types of emitters, viz. online pressure compensating, online nonpressure compensating, inline pressure compensating and inline non-pressure compensating drippers were tested in split-plot design with three replications. Water soluble fertilisers, viz. urea, urea phosphate with sulphate of potash and sulphate of potash were used for fertigation. The maximum fruit yield of 59.8 t/ha, water-use efficiency of 21.17 kg/m3 water, benefit:cost ratio of 3.75 and internal rate of return of 62.16% and the minimum payback period of 2.26 years were recorded in fertigation with 100% RDF through online pressure compensating emitters. Fertiliseruse efficiency increased with decrease in fertigation level and the maximum value of 270.1 kg fruit/kg of NPK was recorded with 60% RDF through online pc emitters.
