ABSTRACT
A field experiment was conducted during 2014-2015 to study the effect of various sources and levels of fertilizers on nutrient use efficiencies of sugarcane in Madurai West block of Madurai district, Tamil Nadu. The soil of the experimental field was sandy clay loam with neutral pH and free from salinity. The soil was medium in organic carbon, available nitrogen and potassium and high in available phosphorus. Agronomic efficiency, apparent recovery efficiency and partial factor productivity were the highest with the application 100% recommended N and K along with 50% recommended P through 20:20:0 complex compared to other levels and sources of fertilizers. The farmers fertilizer practice recorded the lowest agronomic and apparent recovery efficiency, whereas the treatment with the application of 125% recommended N and K along with 75% recommended P with the fertilizer source as 15:15:15 complex recorded the lowest partial factor productivity.
Key words :
Agronomic efficiency, Apparent recovery, Levels of fertilizer, Nutrient uptake, PFP, Sources of fertilizers, Sugarcane, Yield attributes.
