Crop growth rate and developmental characteristics of Indian mustard var vardan to varying levels of nitrogen and sulphur

The present field experiment was conducted on Vardan variety of Indian mustard during Nov, 2003 to March, 2004 to find out the effect of various doses of nitrogen (0, 60, 80, 100, 120 and 140 kg/ha) and sulphur (0, 20, 40 and 60 kg/ha) on crop growth rate and various developmental characters. The results indicated that 50% flowering and 50% podding started significantly earlier in the plots fertilized with nitrogen and sulphur compared to control plot but the days to attain maturity were not affected by fertilization. The grain growth duration was significantly longer by 9 days for fertilized plots compared to control. However, crop growth rates at different stages of growth were not affected by fertilizer application.
