Abstract:

In two consecutive seasons a field experiment was conducted in randomised block design replicated thrice with twelve treatments including two sets of treatments, viz. initial weedy and initial weed free treatment with 15 days interval up to harvesting. They are weeds up to 15, 30, 45, 60, 75 days after emergence (DAE), weedy treatment and weed free up to 15, 30, 45, 60, 75, weed free treatment to assess the effect of weed flora on growth and yield of groundnut. The results show that the growth parameters like Plant height (59.80, 50.56 and 55.18 cm), Dry matter (28.12, 24.49 and 26.3 g/plant), LAI (2.56, 2.47, 2.51) and yield attributes of groundnut were significantly with increasing of initial weed free treatments and highest number of pods per plant (22.20, 16.52 and 18.80), number of seeds per pod (1.90, 1.80 and 1.85), seed index (24.01, 23.52 and 23.59), seed yield (1.35, 0.94 and 1.15 t/ha) and STOVER yield (3.87, 3.37 and 3.62 t/ha) and Harvest index (50.24, 21.84 and 23.86%) were found in weed free check. Similarly, lowest was found in weedy check in both season.
