Abstract:

A study was conducted at the Crop Farm, Eastern University, Sri Lanka during maha, 2007 to assess the effect of groundnut intercropping on brinjal yield and yield components. Experiment was designed in RCBD with a plot size of 3.0m x 1.5m. Brinjal variety Paluhamam Purple and groundnut variety Indi were used for this study. Five treatments were included viz. brinjal as a sole crop (90 cm × 60 cm) (T1), groundnut as a sole crop (45 cm × 30 cm) (T2), brinjal (90 cm × 60 cm) with groundnut (90 cm × 30 cm) in alternative rows (T3), 60/150 cm paired row planting of brinjal with two rows of groundnut (T4) and 75/120 cm paired row planting of brinjal with single row of groundnut (T5). Results showed that reduced interrow spacing did not change the brinjal yield. It was slightly higher (8.89 kg/plot) in T4 followed by T3(7.84 kg/plot). Minimum brinjal yield was obtained in T1(6.52 kg/plot) compared with other treatments. In case of intercropped groundnut, yield and yield components did not significantly differ among the treatments. However, 60/150 cm paired row of brinjal with two rows of groundnut (T4) would be the suitable planting geometry to obtain higher yield of brinjal in intercropping.
