Abstract

An experiment was undertaken to evaluate fresh leaf yield and flowering responses of two Brassica juncea varieties (Paida and ZGS) to varying rates of nitrogen fertilizer ammonium nitrate (0; 100; 200 and 300 kg ha-1) during winter of 2007 under irrigation. The experiment was arranged as a 2×4 factorial treatment structure, laid in a randomized complete block design (RCBD) with three replications. Fresh leaf yield and days to 50% flowering were measured during the course of the experiment. There was significant difference (p<0.001) in fresh leaf yield of the varieties. Fresh leaf yield was significantly increased to 37.3 t ha-1 when 300 kg ha-1 of NH4NO3 was applied as compared to control plots (0 kg ha-1) which gave a yield of 32 t ha-1. There was no significant difference (p>0.05) in days to 50% flowering due to different N treatments. There was significant difference (p<0.05) in days to 50% flowering of the two varieties, with Paida flowering 24 days later than the ZGS mustard. N level had significant effect only on fresh leaf yield whilst variety had significant effect on both fresh leaf yield and days to 50% flowering. The N rate of 300 kg NH4NO3 ha-1 was considered as the optimal dosage and Paida the best variety.
