Germination percentage in sorghum with different seed dressers and their effect on oviposition of sorghum shoot fly

Abstract

The present research was conducted to study the germination percentage in sorghum with different seed dressers and their effect on oviposition of sorghum shoot fly during 2013-14. The results revealed that the treatment thiamethoxam 35 FS @ 5 ml/kg seeds recorded highest percentage of germination (92%) and all the treatments were significantly superior over control (68%). Other seed dressers which recorded better germination in order of merit were imidacloprid 17.8 SL @ 10 ml/kg (90%), chlorpyriphos 20 EC @ 4 ml/kg (80%), carbosulfan 25 EC @ 6 ml/kg (74%) and cartap hydrochloride 50 SP @ 2 g/kg (72%) germination. Maximum numbers of eggs were observed on the cartap hydrochloride 50 SP@ 2 g/ kg treated seed plot. The yield data indicate that the treatment with thiamethoxam 35 FS @ 5 ml/kg seed produced highest grain yield (3462 kg/ha). The maximum net monetary returns 1:56.25 (ICBR) were realized by the treatment thaimethoxam 35 FS@5 ml/kg seed.
