ABSTRACT
A field experiment was conducted at ZARS, V. C. Farm, Mandya during 2015-16 to know the effect of subsurface drip fertigation intervals and fertilizer levels on yield and quality of sugarcane. The treatments consisted of two factors viz., three fertigation intervals (fertigation once in 2, 4, and 6 days) and four fertilizer levels (75, 100, 125 and 150 % of recommended dose of fertilizer) along with conventional method of sugarcane cultivation. The results revealed that the Fertigation once in 2 days has given on par results on the quality parameters viz., brix (20.46 %), pol (19.18 %), purity (93.28%) and CCS (13.63 %) with lesser reducing sugars (2.83 %) but recorded significantly higher cane yield and sugar yield (281.4 and 38.38 t ha-1 respectively) than other fertigation intervals. Similar results was also observed under fertilizer levels, application of 125 per cent RDF through subsurface drip fertigation recorded higher quality parameters viz., brix (20.89%), pol (19.48%), purity (94.83%) and CCS production (13.81%) with lesser reducing sugar (2.86%) but cane and sugar yield was higher in 150 per cent of RDF (283.1 and 39.11 t ha-1). The interaction between fertigation intervals and fertilizers levels was not-significant on quality parameters but significantly higher cane yield and sugar yield (308.30 and 42.17 t ha-1) was recorded with fertigation once in 2 days with 150 per cent of recommended dose of fertilizer compare to conventional method of sugarcane cultivation (158 and 21.31 t ha-1). The brix, pol, purity and CCS per cent were increased with increase in fertilizer levels up to 125 per cent RDF then declined by further increased in fertilizer level.
Key words: Yield, Fertigation intervals, Quality, Subsurface drip fertigation, Sugarcane.
