Abstract

A field experiment was conducted at Regional Sugarcane and Rice Research Station, Rudrur during the two successive seasons of 2018-19 and 2019-20 to find out the performance of three sugar cane varieties (97 R 129, 2010 R 854 and Co 86032) under four fertilizer levels (75, 100, 125 and 150 % RDF). The experiments consist of 12 treatments replicated thrice in a Randomized Block Design with factorial concept. The highest cane yield (119.1 t ha-1) was recorded with application of 150 % RDF which was on par with application of 125%  RDF (114.4 kg ha-1) and significantly superior over rest of the treatments. The lowest yields recorded under 75 % RDF (87.50 t ha-1). Among the varieties tested, 2010 R 854 recorded highest cane yield (112.2 t ha-1) which was significantly out yielded than the rest of the two varieties (97 R 129 and Co 86032). The highest benefit cost ratio recorded in 125% RDF followed by 150 % RDF and 100% RDF. Among the varieties, 2010 R 854 recorded highest benefit cost ratio over rest of the varieties. Based on the results of the investigation it is concluded that adoption of promising sugarcane variety 2010 R 854 with 125 % RDF (312.5-125-125 kg N-P2O5-K2O ha-1) is recommended for Vertisols of Northern Telangana Zone.
