Abstract
A field experiment with jute (Corchorus sp.) varieties was conducted during the rainy season of 1997 and 1998 at Raigarh, with 4 sowing dates and 2 fertility levels. Significantly higher values of growth, yield attributes and fibre yield were recorded with earlier sowing than delayed sowing. Maximum fibre yield of 2,412 kglha was obtained when the crop was sown on 10 June, which drastically decreased with delay in sowing on 20,30 June and 10 July (1,995, 1,492 and 1,240 kglha respectively). Tossa jute (Corchorus olitorius L.) variety JRO 524 (1,844 kglha) gave higher fibre yield than to white jute (C. capsularis L.) JRC 212 (1,726 kglha). The white jute JRC 212 gave higher fibre Zield when sown on 10 June with fertility level of 60 : 40 : 30 kg N : P,O,: K,O/ha, whereas the sowing of JRO 524 can be extended up to 20 June with fertility level of 60 : 45 : 45 kg N : P,O,: K20/ha.
