Abstract:

Surveys were carried out in eight districts of Jharkhand. Hill infestation, tiller infestation and infected grains with false smut of rice were recorded higher in hybrid rice in comparison to none hybrid (HYV) rice in all surveyed areas of Jharkhand. Hill infestation with false smut of rice ranged from 3.8 to 31.7 % in twenty one rice cultivars. Highest tiller infestation with false smut was recorded in Arize 6444 (24.8%), followed by PAC 801 (22.5%), KRH 2 (22.3%), 25P25 (21.7%) and PHB 71 (20.3%). Highest false smut infected grains/panicle was recorded in PAC 801 (8.6) followed by Arize 6444 (8.2). Application of higher level of N-fertilizer in rice recorded higher tiller infestation of false smut of rice, higher number of false smut infected grains /panicle and higher hill infestation of false smut of rice during 2016 and 2017 crop seasons. Closer spacing in rice recorded higher tiller infestation of false smut of rice, higher number of false smut infected grains/ panicle and higher hill infestation of false smut of rice in all three levels N-fertilizers i.e., 90, 120 and 150 Kg N ha-1 during above two crop seasons. False smut symptom was observed on all three levels of nitrogen having five spacing of rice in both 2014 and 2015 crop seasons. Highest mean grain yield of 78.5 q ha-1 was recorded in plots where N- fertilizer was applied @120 Kg ha-1 and spacing of rice was 25 cm X 25 cm, this treatment also recorded mean tiller infestation of 7.8%, lowest mean infected grains/ panicle of 6.3 and lowest mean hill infestation of 11.7%. This treatment was at par with treatment having N- fertilizers was applied @ 120 Kg ha-1 and spacing of 20 cm X 20 cm, which recorded mean grain yield of 77.0 q ha-1, mean tiller infestation of 9.1% and mean hill infestation of 6.6%.
