Effect of integrated nutrient management on yield and nutrient uptake in sorghum (Sorghum bicolor)
Year: 2001
Type: article
Abstract: A field experiment was conducted during the rainy ( kharif) season of 2010 and 2011 at Rajasthan College of Agriculture, Udaipur, to study the effect of integrated nutrient management on yield and nutrient uptake in sor- ghum [ Sorghum bicolor (L.) Moench]. Two levels of farmyard manure (FYM) (0 and 10 tonnes/ha), four fertility lev- els based on soil test recommendation (0%, 50%, 75% and 100% NPK) and four biofertilizers (No inoculation, Azotobacter, phosphate solubilizing bacteria (PSB) and dual inoculation of Azotobacter + PSB) were compared. Application of 10 tonnes FYM/ha significantly increased grain (27.7, 28.3%) and stover (11.3, 12.9%) yields during both the years and as well as nutrient content (NPK) and their uptake over the control. Significant enhancement in grain (26.8 and 28.5%) and stover (11.9 and 13.0%) yields were observed with the application Azotobacter + PSB over no inoculation. Application of 100 % NPK increased grain (45.3 and 44.6%), stover (12.2 and 12.3%) yields and harvest index (22.9%) over the control. Improvement in N,P and K content and their uptake in grain (61.6, 15.3 and 22.0%) and stover (84.7, 29.9 and 243.2%) were also noticed with 100% NPK over control.
