Abstract
Late blight, (Phytophthora infestans) of potato is the most devastating disease which was found to be prevalent in all the potato growing areas of Kashmir valley. In the present study, the effect of different amendments applied to soil singly or in combinations on late blight development and tuber yield of potato cv. Kufri Jyoti was assessed during 2016 and 2017 cropping seasons. In this experiment, seven different treatments of amendments which include vermicompost, FYM, sheep manure, Trichoderma viride, (Vermicompost + FYM),( T. viride + FYM), (Vermicompost + T. viride) along with untreated/un-amended control(check) were evaluated against the incidence and intensity of the disease at two growth stages viz., during flowering and ten days before dehaulming stage of the potato crop cv. Kufri Jyoti. It was found that significant reduction in the late blight incidence and intensity was obtained with the application of different soil amendments compared to control. Soil amendment particularly with T. viride + FYM combination resulted in the lowest leaf blight incidence and intensity of (26.66 and 28.88%) and (17.04 and 20.05%) at flowering stage, and (42.21 and 44.44%) and (23.61 and 25.90%) at dehaulming stage, respectively compared to the incidence of 51.11 and 38.77 per cent and intensity of 79.99 and 47.93 per cent, respectively, at flowering and dehaulming stages obtained in un-amended control (check) plots during 2016 and similar trend of results were obtained during 2017 where lowest disease incidence and intensity were found in the amendment with T.viride + FYM, followed by amendments with FYM or vermicompost alone compared to the un-amended control. Similarly highest tuber yield and grade A tubers were obtained with the soil amendment of T.viride + FYM followed by the amendment with FYM alone, whereas, lowest tuber yield and grade A tubers were obtained in un-amended control.
