Abstract:
The light texture coastal sandy soils are also well known for the deficiency of both macro and micronutrients. In sesame production and improving the yield and quality, the Zn and Mn plays a vital role. A field experiment was conducted to find out the effect of organics and micronutrients on the yield, nutrient uptake by sesame and soil fertility in coastal sandy soil. The experiment was carried out in a farmer’s field at Ponnanthittu coastal village in Cuddalore district, Tamil Nadu during January –April 2015. The initial fertility status of experimental soil was pH – 8.41, EC- 1.65 dS m<sup>-1</sup>, organic carbon 2.30 g kg<sup>-1</sup> and represented low status of micronutrients. The available NPK, were low, low and medium status, respectively. The various treatments included were, T<sub>1</sub>-100% NPK (Farmer’s Practice), T<sub>2 </sub>-125% NPK, T<sub>3 </sub>-150% NPK, T<sub>4</sub>-125% NPK + CCP @ 12.5 t ha<sup>-1</sup>, T<sub>5 </sub>-125% NPK + FYM @ 12.5 t ha<sup>-1</sup>, T<sub>6 </sub>-150% NPK + CCP @ 12.5 t ha<sup>-1</sup>, T<sub>7 </sub>-150% NPK + FYM @ 12.5 t ha<sup>-1</sup>, T<sub>8 </sub>-125% NPK+CCP @12.5 t ha<sup>-1</sup>+ZnSO<sub>4</sub> @ 25 kg ha<sup>-1 </sup>+ MnSO<sub>4 </sub>@ 5 kg ha<sup>-1</sup>, T<sub>9 </sub>-125% NPK+FYM @12.5 t ha<sup>-1</sup>+ZnSO<sub>4</sub> @ 25 kg ha<sup>-1 </sup>+ MnSO<sub>4 </sub>@ 5kg ha<sup>-1</sup>, T<sub>10</sub>-150% NPK+CCP @12.5 t ha<sup>-1</sup>+ZnSO<sub>4</sub> @ 25 kg ha<sup>-1</sup>+ MnSO<sub>4 </sub>@ 5 kg ha<sup>-1</sup>, T<sub>11</sub>-150% NPK+FYM@12.5 t ha<sup>-1</sup>+ZnSO<sub>4</sub> @ 25 kg ha<sup>-1</sup>+ MnSO<sub>4 </sub>@ 5 kg ha<sup>-1</sup>. The above treatments were arranged in a Randomized Block Design (RBD) with three replications and tested with sesame var. TMV 7 as test crop. The results of the study clearly indicated that the combined application of 125% NPK along with composted coirpith @ 12.5 t ha<sup>-1 </sup>+ ZnSO<sub>4</sub> @ 25 kg ha<sup>-1 </sup>and MnSO<sub>4 </sub>@ 5 kg ha<sup>-1 </sup>(T<sub>8</sub>) significantly increased nutrients availability, enzyme activity, microbial population and yield of sesame. The increased seed and stover yield recorded was 766 and 1706 kg ha<sup>-1</sup> as compared to control.
