Effect of Planting Time, Plant Population and Row Spacing on Yield and Other Characteristics of Pigeonpeas, Cajanus cajan (L.) Millsp.

Abstract

Pigeonpea cultivar Kaki was grown during 1970-71 to determine the effect of planting date, plant population and row spacing on green-pod yield, date of flowering, plant height, protein content of the seed and yield components. Green-pod yields were significantly higher in plantings made during early April, May and June than during late September and October. Yield also tended to be higher at lower spacing between rows, and at highest populations, regardless of row spacing. Plant height, number of days to flower and protein percent of the dry seed were unaffected by row spacing and plant population, but these factors were affected significantly by date of planting. Pods per plant increased markedly as spacing was increased and with early plantings. Date of planting, row spacing and plant population had no affect on seed size or number of seeds per pod.
