A comparison of interactive effects showed that, at fixed nitrogen level, each increase in intra row
spacing from 5 to 15cm resulted in corresponding increase in the NL, NPB, SDM, CY and GYP. When the effect
of increasing nitrogen level at fixed intra row spacing for these characters were considered, it was observed that,
application of 60 and 80kgN/ha produced statistically same NL at 5 and 10cm, NPB at 5 and 15cm and GYP at
10 and 15cm intra row spacing. Application of nitrogen fertilizer beyong 40kgN/ha produced same TDM at 5cm.
