Influence of Levels of N on Yield and Yield Components of Rice Varieties

Abstract

                                Eight medium duration (120-140 days) rice varieties viz. Jaya. IET 1039. JET 2295. JET 2885, IET 1991. IET 1996, IET 2254 and Bhavani were studied under five levels of nitrogen (0, 50, 100, 150 and 200 kg/ha) in two seasons both in Samba (kharif) July to November and Navarai (Rabi) January to May. Their yield poten- tials under different nitrogen level was assessed. IET 2254 (RP-4-14) was found promising high yield and suitable for Tamil Nadu. It's grain quality is fine as that of Bhavani. It is also suitable for both the seasons. It's performance both under low and high fertility level is better than Bhavani and Jaya.
