Micronutrients deficiencies may affect fundamental physiological and biochemical processes causing hormonal imbalance hence reduction in yield. Application of microelement fertilizers increase crop yield and can enhance plants resistance to environmental stresses. To assess the role of micronutrients, field experiments were conducted at NARC Islamabad, Pakistan by using four sesame cultivars (SG-30, TS-3, TS-5 and TH-6) and four micronutrient treatments (control, Zn, B and Mn) during summer 2014 and 2015 in randomized complete block design with split plot arrangement having four replications.
Results revealed significant variations for the main effects of all studied factors (cultivars, micronutrient and year). Micronutrients application significantly increased all yield attributes over control. Zn, B and Mn increased capsule length, capsule weight, capsules plant-1, seeds capsule-1, 1000 seed weight, seed yield and oil yield of sesame. Maximum mean values of capsules plant-1, seed yield and oil yield were observed for cv. SG-30, while the cv. TH-6 was lowest for these parameters. It may be concluded that micronutrient fertilizers application @ 10kg ZnSO4 ha-1, 10kg Borax ha-1 and 5kg MnSO4 ha-1 would enhance yield and yield related traits provided proper cultivar is selected.
Key Words: Sesame, micronutrients, seed yield.
