Abstract:

Field experiments were conducted in sandy clay loam soils to assess the effect of different levels of fertigation and emitter types on hydraulics of drip irrigation, movement of soil moisture distribution and yield of tomato. The three levels of fertigation i.e. fertigation with 100% recommended dose of fertiliser (RDF), 80% RDF and 60% RDF and four types of emitters viz. online pressure compensating (online pc), online non pressure compensating (online npc), inline pressure compensating (inline pc) and inline non pressure compensating (inline npc) emitters were tried in split plot design with three replications. The fertigation levels were allocated to main plots and the emitter types were assigned to sub plots. Water soluble fertilisers viz. urea, urea phosphate with SOP and sulphate of potash were used for fertigation. The emission uniformity test showed better results for pc emitters over npc emitters. The soil moisture distribution under various emitters indicated the highest moisture content below the emitters and it decreases as distance from emitter increases both horizontally and vertically. The treatment with 100% fertigation through online pc emitter based drip system results the maximum fruit tomato yield of 59.8 t/ha since this treatment maintained higher soil moisture contents both in horizontal and vertical direction below the emitter than all other treatments. Further the said treatment had the highest value of emission uniformity (99.04%) amongst all the treatments that have caused uniform distribution of water in the root zone resulting higher yield.
