Deep placement of urea super granules (USG) by hand and machine, and prilled urea (PU) by 2 to 3 split applications in rainfed rice were compared during 1986 and 1987. USG performed better than PU in all the parameters tested. The highest grain yield was obtained from hand placed USG which was identical with machine placed USG and three split application of PU. The highest agronomic use efficiency of nitrogen and nitrogen recovery percentage was obtained with the hand placed USG followed by machine placed USG and the three split application of PU.
