Online published on 15 December, 2016. Abstract A field experiment was conducted in sandy loam soils at S. V. Agricultural College, Tirupati campus of Acharya N.G. Ranga Agricultural University, Andhra Pradesh in randomized block design with factorial concept to study the performance of groundnut cultivars viz., ‘Abhaya’, ‘TAG-24’, ‘Dharani’ and ‘Kadiri-6’ under different plant populations viz., 3.33, 4.44, 5.00 and 6.66 lakh/ha during early kharif, 2013. The results revealed that the highest weed suppressing ability and the highest stature of growth parameters viz., plant height, LAI and DMP were higher with the groundnut cultivar ‘Kadiri-6’ while at their lowest with ‘TAG-24.’ The lowest weed density and dry weight were significantly lesser with the maintenance of plant population of 6.66 lakh plants/ha. However, the yield attributes viz., number of filled pods/plant, 100-pod, 100-kernel weight and pod yield were significantly higher with groundnut cultivar, ‘Dharani’ followed by ‘TAG-24’. Among the plant populations tested, the growth parameters viz., plant height, LAI and DMP were significantly higher at plant population of 6.66 plants/ha where as the yield components viz., number of filled pods/plant, 100-pod and 100-kernel weight were significantly higher at plant population of 3.33 lakh/ha. However, the highest pod yield of groundnut was obtained at plant population of 5.00 lakh/ha, which was closely followed by 3.33 lakh/ha. The maximum net returns with higher benefit-cost ratio of groundnut cultivation during early kharif in sandy loam soil was obtained with groundnut cultivar ‘Dharani’ at plant population of 3.33 lakh/ha Top Keywords Cultivar, Dry matter production, Groundnut, Plant Population, Yield attributes, Yield.
