Field experiment was conducted at Experimental Farm, Annamalai University, Annamalainagar to study the effect of zinc chelated (BOLD) and iron chelated (GRIP) on the growth and yield of rice, during 2010 (Thaladi). The experiments were laid out in randomized block design. The experiments consists of nine treatments viz., (T1) 2 gm (GRIP) in 1 ltr of water, (T2) 2 gm (BOLD)} in 1 ltr of water, (T3) 3 gm (GRIP) in 1 ltr of water, (T4) 3 gm (BOLD) in 1 ltr of water, (T5) 2 gm liberal zinc chelate in 1 ltr water, (T6) 2 gm liberal iron chelate in 1 ltr water, (T7) 3 gm liberal zinc chelate in 1 ltr water (T8) 3 gm liberal iron chelate in 1 ltr water, (T9) control (no foliar spray). Among the different treatments tried, foliar application of zinc chelated (BOLD) @ 2 g in 1 ltr of water favourably influenced the yield components viz., No. of filled grains panicle-1, panicle length, Test weight, grain yield 4858 kg ha-1 and straw yield and nutrient uptakeof 114.27 kg Nha-1, 38.43 kg P2O5 ha-1and 126. 5 kg K2O ha-1. This was followed by iron chelated (GRIP) @ 2 g in 1 ltr of water. The control treatment (no nutrient application) registered the lowest values in yield components and yield 3126 kg ha-1 of rice and nutrient uptake.
