Effect of nutrient management techniques on soil fertility and yield of french bean (Phaseolus vulgaris) under Northern Dry Zone of Karnataka

Yogeeshappa H, Rajeshwari Nidagundi, Shoba Hugar

The field experiment was conducted during the Kharif season from 2015-16 to 2017-18 at College of Horticulture, Munirabad (Koppal), University of Horticultural Sciences, Bagalkot, Karnataka to evaluate the different levels of fertilizers application through different approaches in french bean (Phaseolus vulgaris) under alfisol soils. Application of 100 per cent fertilizers application based on specific nutrient management (SSNM) approach with target yield of 15 t ha-1 recorded significantly higher fresh pod yield (T3: 15.1 t ha-1) and it was on par with treatment had 100 per cent fertilizers application based on soil test crop response (STCR) approach with target yield of 15 t ha-1. The Soil pH (1:2.5) and electrical conductivity (dSm-1) as influenced by the application of different levels fertilizers through different approaches at harvest of french bean crop were recorded on par among the treatments. Similarly, application of 100 per cent fertilizers based on site specific nutrient management (SSNM) approach with target yield of 15 t/ha (T3) at harvest showed significantly higher nutrients levels (T3: 396.7, 57.7 and 572.3 Kg N, P2O5 and K2O ha-1, respectively), it was on par with 100 per cent fertilizers application based on soil test crop response (STCR) approach with target yield of 15 t/ha (T6). And the same trend of results were observed soil organic carbon at harvest.
