An experiment was conducted during summer seasons of 1993 and 1994 at instructional farm, Rajasthan College of Agriculture, Udaipur to find out the effect of irrigation schedules, fertilizer levels and weed control methods on weed parameters, nutrient uptake and quality of summer peanut. Result revealed that amongst weed control methods pendimethalin+hoeing reduced weed density and weed dry weight significantly over other methods and consequently increased weed control efficiency. Irrigati on scheduled at 0.70 IW/CPE ratio improved nutrient uptake, protein and oil content, oil and pod yield over 0.40 IW/CPE ratio but was at par with 1.0 IW/CPE. Nutrient uptake by the crop increased with the increase in fertilizer doses upto 40 kg N/ha in combination with 80 kg P2O5/ha. However, protein and oil content and pod yield were at par in treatment of 30–60 kg N P2O5. Pcndimethalin+hoeing significantly improved nutrtent uptake and quality of peanut over other method of weed control viz., fluchloralin+hoeing, hoeing alone and weedy check.
