An experiment was carried out at KVK, Shuhama, during Rabi 2011–12. The experiment was laid out in a split plot design with four replications. The treatments included three sowing dates and six thinning managements assigned to main and sub plots, respectively. The findings of the study indicated that sowing on Ist October was found to cause significant improvement in various growth and yield attributes viz; plant height, number of leaves per plant, green area index, dry matter accumulation siliquae plant−1, seeds plant−1 and 1000 seed weight. Relative economics, seed and straw yield were also maximum when sowing was done on Ist October. Among different thinning management treatments, 50% thinning at 10 days after emergence and remaining 50% at last week of November improved growth characters and thereby recorded highest yield attributes which resulted in increase in the biological yield as well as economic yield. The maximum net profit ha−1 also showed the same trend. Results indicated that for achieving higher seed yield along with improved quality characters, sowing of brown sarson under Kashmir conditions should be done in first week of October and that thinning should be done 50% after 10 days of emergence and remaining 50% thinning in last week of November.
