Effect of integrated nutrient management on growth and tuber yield of potato (Solanum tuberosum L.) under red and lateritic belt of West Bengal

Author(s): Subhranath Hensh, Ganesh Chandra Malik, Mahua Banerjee and Tanmoy Shankar
Abstract: A field experiment was conducted to study the effect of integrated nutrient management on growth and tuber yield of potato (Solanum tuberosum L.) under red and lateritic belt of West Bengal. The study was laid out during 2014-15 and 2015-16 at Bahadurpur, Birbhum district of west Bengal which consists of 14 treatments and carried out in randomized block design with three replications. The results revealed that treatment T10: 80% RDN through chemical fertilizer + 20% through vermicompost + biofertilizer exhibited highest growth attributes i.e. plant height (43.3 cm), leaf area index (4.42), dry matter accumulation (583.45 g m-2) and crop growth rate (18.38 g m-2 day-1) followed by treatment T11: 80% RDN through chemical fertilizer + 20% through mustard oil cake + biofertilizer and T9: 80% RDN through chemical fertilizer + 20% through FYM + biofertilizer. This treatment T10: 80% RDN through chemical fertilizer + 20% through vermicompost + biofertilizer also showed highest total number of tubers per plant (9.05 tubers plant-1), tuber weight per plant (517.8 gm) and tuber yield (32.05 t ha-1) of potato and the tubers yield was 55% higher over 100% RDN through chemical fertilizer (T1). The higher tuber yield achieved in 80% RDN through chemical fertilizer + 20% through vermicompost + biofertilizer might be due to the integration of inorganic, organic and biofertilizers might have improved the physico-chemical conditions of the soil.
