Abstract:

A field experiment was conducted for two consecutive seasons to assess the impact of four plant spacing (10, 20, 30 and 40 cm) and three weeding levels (no weeding, weeding once (at two weeks from sowing) and weeding twice (at two weeks and at four weeks) on growth and yield of peanut (groundnut) in rain-fed under Kordofan (Sudan) conditions. A randomized complete block design in four replications was used. The results showed that plant spacing of 10 cm gave 40% more yield than that at 40 cm and was the best for maximizing yield under rain-fed conditions. The growth and yield attributes of groundnut were significantly reduced when the crop was left un weeded. Weeding twice had the highest number of pods per plant, 100- Kernel weight, pods yield per plant and final pod yield (t/h). Weeds reduced pod yield by about 40%. The field was dominated by Cenchrus biflours L.
