Author(s): J. STEN, S. MAHAPATRA AND S. DAS
A field study was conducted to find out the effect of different combinations of nitrogen, phosphorus and potassium levels against the severity of fungal foliar diseases i.e. late blight, early blight, leaf blotch and diseases complex and yield of potato grown in four different fertility gradient soils (low-S1, medium-S2, moderate-S3 and high-S4). Maximum yield as well as low disease
severity was observed in S1 at N150P125K100 kg ha-1combination, S3, at N250P125K100 kg ha-1 combination and at N250P125K125kg ha-1 combination in S2 and S4. This study showed that soil testing plays an important role in management of disease in potato before fertilizer application.
