Influence of NPK fertilizers on blast incidence, productivity and profitability of short duration improved finger millet genotypes

Abstract

High yielding varieties are more responsive to NPK fertilizers compared to the traditional varieties in increasing the grain yield. A field experiment was conducted during kharif, 2018-19 at Agricultural Research Station, Vizianagaram to assess the performance of two finger millet improved genotypes (PR 10-35 and KOPN 942) at various levels of NPK fertilizers (75% RDF,100% RDF& 125% RDF) compared to the national checks (GPU 45& GPU 67) and local check (PR 202) varieties. Results revealed that, grain yield and B:C ratio increased significantly from 75% RDF to 100% RDF but was non significant from 100% RDF to 125% RDF. PR 10-35 recorded highest growth and yield attributes among different varieties. Grain yield, B:C ratio were also significantly high for PR 10-35 than KOPN 942 and is also found superior to national and local check varieties. Neck and finger blast incidences were also less in PR 10-35.
