Effect of spacing on hybrid seed yield of piegeonpea hubrid COPH2 (Cajanus cajan L.Millsp)

Abstract

Field experiments conducted during Sep. 2000 and July 2001 with the parental lines of COPH 2 pigonpea hybrid revealed that seed yield attributes were not influenced by different spacings. However, the plants spaced at 45 x 20 cm spacing (44446 plants ha) recorded significantly higher seed yield of 728 kg ha in September sown crop, which was 7.69 per cent increase over July sown crop. The resultant seed showed nonsignificant differences in seed quality.
