Abstract:
A field experiment was conducted at Theerthampalayam village, Cuddalore distict on saline soil to study the Response of tomato to iron nutrition in saline soil. The experiment was laid out in Randomized Block Design and replicated three times. The treatments were T<sub>1</sub>- RDF + Water spray (Control), T<sub>2</sub>- RDF + Soil application FeSO<sub>4 </sub>10 kg ha<sup>-1</sup>,T<sub>3</sub>- RDF+ Soil application FeSO<sub>4 </sub>20 kg ha<sup>-1</sup>, T<sub>4</sub>- RDF + Soil application FeSO<sub>4 </sub>30 kg ha<sup>-1</sup>, T<sub>5</sub>- RDF +Foliar spray 0.25 % (FeSO<sub>4</sub> 45 &amp; 60 DAT),T<sub>6</sub>- RDF + Foliar pray 0.50 % (FeSO<sub>4 </sub>45 &amp; 60 DAT), T<sub>7</sub>- RDF +Foliar spray 1.0 % (FeSO<sub>4</sub> 45 &amp; 60 DAT),T<sub>8</sub>- T<sub>2</sub> + Foliar spray 0.25% (FeSO<sub>4</sub> 45 &amp; 60 DAT), T<sub>9</sub>- T<sub>3</sub>+ Foliar spray 0.25% (FeSO<sub>4</sub> 45 &amp; 60 DAT) T<sub>10</sub>- T<sub>4</sub> + Foliar spray 0.25% (FeSO<sub>4 </sub>45 &amp; 60 DAT) T<sub>11</sub>- T<sub>2</sub> + Foliar spray 0.50 % (FeSO<sub>4</sub> 45 &amp; 60 DAT), T<sub>12</sub>- T<sub>3</sub> + Foliar spray 0.50% (FeSO<sub>4</sub> 45 &amp; 60 DAT), T<sub>13</sub>-T<sub>4 </sub>+ Foliar spray 0.50 % (FeSO<sub>4</sub> 45 &amp; 60 DAT) T<sub>14</sub>- T<sub>2</sub> + Foliar spray 1.0% (FeSO<sub>4</sub> 45 &amp; 60 DAT), T<sub>15 </sub>– T<sub>3</sub> + Foliar spray 1.0% (FeSO<sub>4</sub> 45 &amp; 60 DAT) and T<sub>16</sub>- T<sub>4</sub> + Foliar spray 1.0% (FeSO<sub>4</sub> 45 &amp; 60 DAT).The results revealed that application of either soil or foliar or combined application of iron significantly influenced the tomato yield, iron uptake and iron use efficiency over control. The tomato yield was higher in combined application of soil and foliar iron compared to their individual applications. The highest tomato yield (365.50 q ha-<sup>1 </sup>) and iron uptake (fruit 1112.65 and stover 897.15 g ha-<sup>1 </sup>) was noticed T<sub>12 </sub>Combined application of soil and foliar iron recorded higher agronomic efficiency and apparent iron recovery compared to their individual applications which explained the highest yield in the best treatment.
