Abstract
Background: Sunnhemp is an important bast fibre crop suitable for diversified uses. Recently, its cultivation has started expanding considerably throughout the world particularly for its potential usage in sustainable farming and in reducing use of synthetic fertilizers from agricultural system. Seed production and fibre production are mutually exclusive in sunnhemp because of different photo-period requirements for these purposes and destructive fibre extraction process. The major limitation in sunnhemp popularization cultivation is availability of seed. In this context, present study was undertaken to identify proper sowing time and suitable cultivars, and find correlation of seed yield with weather parameters for Telangana state of India. Methods: Three dates of sowing and six cultivars were tested in split-plot design over two years i.e., 2019-20 and 2020-21. Pooled data over two years were analyzed for important seed yield related traits. Result: The analysis of variance revealed significant influences of sowing dates, cultivars and their interaction on majority of the traits. Among three sowing dates, 2nd week of September was the best suited for seed yield and related traits. The cultivar SUIN 037 recorded maximum seed yield followed by SUIN 053. Among different combinations of treatment, the cultivars SUIN 037 and SH 4 sown during 2nd week of September resulted in maximum and comparable seed yield. The correlation and regression studies showed that the weather parameters had significant influences on yield attributes of sunnhemp.
