The relationship between plant density, yield and quality in Virginia Bunch peanuts in south-east Queensland

Abstract

The effect on yield of plant population level and spatial arrangement of Virginia Bunch peanuts was studied over 3 years in the South Burnett area of Queensland. The three population levels used were 24 700, 32 580 and 49 000 plants ha-1 and at each population level, three planting arrangements were used: 1:1 (square planting), 1:2.5 and 1:5 (extreme rectangularity). Yield generally increased both with increase in plant population level and with decreases in inter-row space. Thus 49 400 plants ha-1 planted at 45 x 45 cm was the highest yielding treatment in 2 out of the 3 years.
