A field experiment was conducted at Pandit Jawaharlal Nehru College of Agriculture and Research Institute, Karaikal to identify a suitable sowing window along with efficient seed hardening and clipping practices in sesame during summer season of 2021 for Karaikal region. The experiment was laid out under Factorial concept of Randomized Block Design (FRBD) with twelve treatments and three replications. The treatments consisted of three factors viz., date of sowing [15th February (D1), 22nd February (D2), 1st March (D3)], seed hardening [without seed hardening (S1) and seed hardening with two per cent moringa leaf extract (S2)] and clipping practices [without clipping (C1) and with clipping (C2)]. The earlier sowing on 15th February along with two per cent MLE seed hardening followed by clipping practices recorded higher growth parameters (plant height, leaf area index, dry matter production, number of branches plant-1) and yield parameters (number of capsules plant-1, number of seeds capsule-1, capsule weight, seed weight plant-1, test weight, seed yield [726 kg ha-1] and stover yield). However, the growth and yield parameters reduced with delayed sowings (22nd February, 1st March). The correlation between weather parameters and seed yield revealed that the total bright sunshine hours, mean morning relative humidity, mean evening relative humidity and HUE during the total life span had a significant positive relationship with the seed yield, whereas the regression studies denoted that the seed yield was positively influenced by mean evening relative humidity, GDD and PTU. Therefore, sowing TMV-7 sesame variety on 15th February along with two per cent MLE seed hardening followed by clipping practices could be appropriate for maximizing yield and monetary returns from summer sesame under irrigated conditions in Karaikal region.
