ABSTRACT

A field experiment on STCR was carried out at the Experimental Farm, Annamalai University to study the effect of INM on grain yield and nutrients uptake by rice (ADT 36) in Vertisols. This experiment consisted of four strips and four blocks. Each strip was divided into 24 plots, out of which 20 NPK treatment combinations and four controls were super imposed to different plots in each strip in a mixed fractional factorial design. Treatment combinations for chemical fertilizers were 5 levels of N (0,50,100,150 and 200 kg ha-1), 4 levels of P2O5 (0,30,60 and 90 Kg ha-1) and 3 levels of K2O (0,40 and 80 kg ha-1). Organic fertilizers FYM (0,12.5 ha-1), Azospirillum (0,2 kg ha-1) were also included into this study. At harvest, grain yield from each plot and from each strip was recorded. Plant samples were also collected, dried, powdered and analysed for N P and K contents and finally uptake were computed. The results indicated that the grain yield, NPK uptake increased from Strip I to IV with the chemical fertilizers along with FYM + Azospirillum
