Effect of cultivars and weed management on quality, nutrient content and uptake in late sown groundnut.

A field experiment was conducted during kharif season of 2010 to study the effect of cultivars and weed management on late sown groundnut productivity. The experiment comprising of 16 treatment combinations (4 cultivars (TG-37A, Malika, HNG-10 and Local) and 4 weed control treatments (Weedy check, Weed free, Pendimethalin 1.0 kg ha-1 and Pendimethalin 1.0 kg ha-1 with one hand weeding at 35 DAS), replicated four times was laid out in split plot design. Maximum uptake of nitrogen and phosphorus, higher net return (49882 Rs. ha-1) and Benefit cost ratio (B: C) recorded in cultivar HNG-10. Maximum and significantly higher shelling percentage was recorded in Malika cultivar. Oil yield and economies was obtaining in weed free treatment, which was significantly higher as compared to Pendimethalin at 1 kg ha-1 treatment; however, it was statistically at par with Pendimethalin at 1 kg ha-1 + HW 35 DAS treatment.
