Crop establishment impact on foliage feeders and Leptocorisa acuta in rice

Abstract

The study was conducted in direct seeded and transplanted rice at at Chaudhary Charan Singh Haryana Agricultural University, Rice Research Station, Kaul during 2014 and 2015 with objective to study the effect of crop establishment methods on incidence of insect pest. The pooled data on incidence of foliage feeders revealed less than one per cent damage in direct seeding and transplanting rice throughout the season during both the years and did not differ significantly. The population of Rice gundhi bug, Leptocorisa acuta varied from 0.08 to 0.16/ hill in direct seeding and 0.10 to 0.12/ hill in transplanted in different weeks during 2014. The population count ranged from 0.14 to 0.22/ hill and 0.10 to 0.16/ hill in direct seeding and transplanting during 2015. The population difference in two methods of study was found non-significant during both the seasons. The population of Leptocorisa acuta with biotic and abiotic factor had non-significant association during both the years.
