Abstract

A field experiment consisting of twelve treatments was conducted for two consecutive years (2010-11 and 2011-12) in factorial randomized block design with three replications at Navsari to study the influence of fertilizer levels and biofertilizers on growth and yield of linseed (Linum usitatissimum L.) under rainfed condition of south Gujarat. The treatments consisted of three fertilizer levels, viz. 100% RDF, 75% RDF and 50% RDF and four biofertilizers viz. Azotobacter, PSB, Azotobacter + PSB and control. Higher values of growth and yield parameters, seed and stover yield were recorded with 100% RDF. Fertilizer level of 100% RDF also recorded significantly higher N and P content in seed and straw and their uptake and oil yield followed by 75% RDF and the lowest under 50% RDF. The results indicated that higher growth, yield attributes and yields, N and P uptake and oil yield were recorded with dual seed inoculation (Azotobacter+PSB). Higher values of gross return, net return and BC ratio were found with the combination of 75% RDF+ Azotobacter + PSB (F1B3). +
