Abstract

Sesamum (Sesamum indicum L.) is one of the oldest oilseed crops and has been cultivated in ancient times. Among the major constraint the phyllody disease, caused by phytoplasma, is major for reducing yield as well as quality of sesamum. Sesamum phyllody is transmitted by leaf hopper, dodder and grafting from infected plant to healthy plant. Phyllody infected plant produced various symptoms such as flower converted into leaf like structure, floral virescence, sterility of flower, witches broom, shoot apex fasciations etc. To mitigate phyllody, this study delves into the impact of different sowing dates on sesamum cultivation during the Kharif season at the experimental farm of the Department of Plant Pathology, College of Agriculture, Latur by employs sesamum varieties JLT-408 and Prachi in a factorial randomized block design (FRBD). The investigation scrutinizes five distinct sowing dates (D1 to D5) to evaluate their effects on leaf hopper populations, disease incidence, and seed yield. The findings revealed that, the sowing of sesamum on 10th August exhibited the lowest leaf hopper population, recording a disease incidence of 6.64% and a yield of 810 kg/ha followed by 30th of July with disease incidence was 9.52% and yield 740 kg/ha. In contrast, the sowing on 20th July showed the highest leaf hopper population, with a disease incidence of 21.60% and a yield of 507 kg/ha. Additionally, among the varieties, JLT-408 displayed the maximum leaf hopper population (0.84 leaf hopper/leaf), coupled with a disease incidence of 16.58% and low yield of 430 kg/ha. Conversely, Prachi demonstrated the minimum leaf hopper population (0.52 leaf hopper/leaf), along with a disease incidence of 10.30% and more yield of 650 kg/ha. Present study highlighted that, late sowing of sesamum reduce outbreak of phyllody disease with minimum leaf hopper count and maximum yield.
