Effect of row orientation and plant density on yield and quality of rainfed barley

Summary Grain and straw yields of barley improved significantly due to N–S, row orientation, 30 cm row spacing and 90 kg/ha seed rate. A plant rectangularity of 13.6 was found most conducive for grain and straw yeilds of barley. None of the malt quality characters were affected wignificantly due to row orientation. A row spacing of 30 cm and a seed rate of 90 kg/ha improved the malt quality characters of barley. Increase in protein percentage at 30 cm row spacing deteriorated the malt quality.
