This experiment was conducted at two locations, in North Kordofan under rain fed conditions for two consecutive seasons (2011/012 and 2012/013), to study the effect of NPK micro doses on leaf area, leaf area index, pod yield and hay yield of six groundnut genotypes. The tested genotypes were arranged in a Randomized Complete Block Design with four replications. Leaf area increased rapidly up to 90 days from planting. Thereafter, it started increase but at slower rate in all treatments. Non significant differences were observed among genotypes and treatments in leaf area at 30 days after planting. At this stage the highest leaf area of about 278.4 cm2 was recorded by ICGV89171 without NPK treatment and the lowest of 149.5 cm2 by ICGV93255 with NPK treatment. At sixty days after planting the significant differences in leaf area were observed, the highest recorded by genotypes ICGV89171 (1278.8 cm2) with NPK treatment while the lowest by line ICGV93255 (743.8 cm2) without treatment. At 90 days after planting the leaf area showed high significant differences among genotypes, the maximum leaf area 1570.1 cm2 recorded by line ICGV92121 with NPK treatment. The Significant differences were record at 60 and 90 days after planting for leaf area index, NPK treatment increase the value 0.30 at all stages of genotypes. Significant varietal differences were observed for pod yield, hay yield, hundred seed weight, and number of pods per plant, while non significant differences were recorded in seeds per pod, shelling percentage and harvest index were not significant. The high significant correlation between leaf area and pod and hay yield were observed, with pod yield was 0.278 and with hay yield was 0.242 respectively.
