A field experiment was conducted to find out the effect of organic manure fortified with micronutrients viz., ZnSO4 and FeSO4 on the growth and yield of rice in coastal saline soil. The experiment was conducted in farmers field at Sillankuppam village in Cuddalore district, Tamil Nadu during October-January 2009. The initial fertility status of experimental soil was pH-8.88, EC-2.16 dS m-1 and OC-0.22 g kg-1 and represented low status of micronutrients. The treatments were T1–Recommended level NPK, T2-NPK+ZnSO4+FeSO4 @ 25 Kg ha-1, T3-NPK+Green manure fortified ZnSO4+FeSO4 @ 75% RL, T4-NPK+Green manure fortified ZnSO4+FeSO4 @ 100% RL, T5-NPK+Green manure fortified ZnSO4+FeSO4 @ 125% RL, T6-NPK+Coir pith fortified ZnSO4+FeSO4 @ 75% RL, T7-NPK+Coir pith fortified ZnSO4+FeSO4 @ 100% RL, T8-NPK+Coir pith fortified ZnSO4+FeSO4 @ 125% RL. The results showed that, micronutrients fortified composted green leaf manure significantly increased the growth and yield parameters of rice as compared to other treatments.

The experiment was conducted in farmers field at Sillankuppam village in Cuddalore district, Tamil Nadu during October-January 2009. The initial fertility status of experimental soil was pH-8.88, EC-2.16 dS m-1 and OC-0.22 g kg-1 and represented low status of micronutrients. The treatments were T1–Recommended level NPK, T2-NPK+ZnSO4+FeSO4 @ 25 Kg ha-1, T3-NPK+Green manure fortified ZnSO4+FeSO4 @ 75% RL, T4-NPK+Green manure fortified ZnSO4+FeSO4 @ 100% RL, T5-NPK+Green manure fortified ZnSO4+FeSO4 @ 125% RL, T6-NPK+Coir pith fortified ZnSO4+FeSO4 @ 75% RL, T7-NPK+Coir pith fortified ZnSO4+FeSO4 @ 100% RL, T8-NPK+Coir pith fortified ZnSO4+FeSO4 @ 125% RL.
