Abstract

Field trials were conducted in randomised block design on CV.MCU 9 during 1978-79 winter and 1980 summer seasons with the following nine spacings as treat- ment viz. 75 X 30 cm 75 X 45 cm, 75 X 60 cm, 75 X 75 cm 90 x 30 cm, 90 X 45 cm, 90 X 60 cm, 90 X 75 cm and 90 X 90 cm. The results revealed that a spacing of 90 X 60 cm in both the seasons was found optimum to increase the seed yield as well as seed germination and seedling vigour The increased seed yield was attributed to more number of bolls per plant, more number of seeds per boll, higher 100 seed weight and higher percentage of recovery of matured seed in plants planted at 90 X 60 cm spacing than in others.
