In the coastal areas of Tamilnadu, the deficiency of micronutrients especially zinc and manganese are the most common in coarse textured sandy soils. To study the effect of vermicompost and micronutrients fertilization on the productivity of sesame in coastal saline sandy soil. A field experiment was conducted in a farmer’s field at Maanampaadi coastal village, near Chidambaram during February- May, 2016. The experimental soil was sandy in texture and taxonomically classified as Typic Usticpsaments. The initial soil had the following characteristics (0-15 cm layer) of the experimental site were, pH–8.37 and EC–1.58 dS m-1. The soil registered low organic carbon status of 2.31 g kg-1, 134.56 kg ha-1 of alkaline KMnO4 – N; 9.43 kg ha-1 of Olsen–P and 159.31 kg ha-1 of NH4OAc-K. The available zinc (0.69 mg kg-1) and manganese content (0.94 mg kg-1) of soil is below the critical level, respectively. The various treatments evaluated were T1–Control (RDF alone/Farmers practice), T2–RDF + Vermicompost (VC) @ 5 t ha-1,T3–RDF + ZnSO4 @ 25 kg ha-1 soil application (SA) + MnSO4 @ 5 kg ha-1 (SA), T4–RDF + ZnSO4 @ 0.5% foliar application (FA) + MnSO4 @ 0.5% (FA), T5–RDF + (ZnSO4 + MnSO4) SA + (ZnSO4 + MnSO4) FA, T6–RDF + VC (ZnSO4 + MnSO4) SA, T7–RDF + VC + (ZnSO4 + MnSO4) FA, T8–RDF + VC + (ZnSO4 + MnSO4) SA + (ZnSO4 + MnSO4) FA, T9– RDF+VC + (50% ZnSO4 + 50% MnSO4) SA and T10–RDF + VC + (50% ZnSO4 + 50% MnSO4) SA + (ZnSO4 + MnSO4) FA with three replications were studied under Randomized Block Design (RBD) using sesame var. TMV 7. The results revealed that, the combined application of recommended dose of NPK + vermicompost @ 5 t ha-1 along with 50 per cent recommended dose of ZnSO4 @ 12.5 kg ha-1 + 50% MnSO4 @ 2.5 kg ha-1 through soil and foliar spray of both the micronutrients (ZnSO4 + MnSO4) @ 0.5 per cent twice at critical stages viz., pre flowering and flowering stage was (T10) was significantly superior in increasing the yield, quality, nutrient uptake and economics of sesame.
