Abstract:
A field experiment was conducted at SRS, Vuyyuru in order to study the performance of promising pre release clones of sugarcane under saline water irrigated conditions in sugarcane ratoon crop. The clones such as 2004 V 76, 2005 V 96, 2005 V 170, 2006 V 60, 2006 V 71 and 2006 V 87 were tested against check Co7219. The water used is having pH 7.60, E.C 2.41 dS m^-1, TDS 1566 mg/l, total hardness 540 ppm and chlorides 600 ppm. All the promising pre release clones recorded more yield, quality, nutrient uptake and nutrient availability in post harvest soils compared to check variety i.e Co 7219. Among the clones tested, 2006 V 71 recorded highest yield, CCS yield and 2005 V 96, 170 and 2006 V 87 were on par with 2006 V 71. Nutrient uptake was also more by 2006 V 71 followed by 2007 V 87 and 2005 V 96. E.C of post harvest soils has shown non significant effect. pH, organic carbon, nutrient availability of nitrogen, phosphorus and potassium were more in the soils harvested with 2006 V 71 and 2006 V 87, 2005 V 96 were on par with 2006 V 71.
