The objective of the test is to determine the best formula of the NPK elements for two local varieties improved of corn. The studied plant material is composed of local populations improved P1, P2. The factorial test is driven with two P1 varieties, P2 and four doses of NPK according to an experimental device in blocks of Fischer to four blocks. The doses of 20 – 10 – 10, 30 – 15 – 15, 10 – 5 – 5 and 40 – 20 – 20 correspond respectively to the T1 treatments, T2, T3 and T4. On the T2 (2,073 m ± 0,009) P1 is observed of the heights raised of stem. The T4 (1, 85 m ± 0,173) recorded a stem raise of P2. The T2 (30, 75 ± 1,500) P1 reached the highest number of grains in a row. The T1 (30, 75 ± 1,258) P2 got high number of grains in a row. Greater number of grains in an ear is observed on T3 (520 ± 15,491) of P1. The greatest number of grains per ear is noted on the T2 (510,5 ± 10,630) of P2. The T2 (4, 20 t ha-1 ± 0,12) P1 recorded better outputs in grains. The T1 (4,035 t ha-1 ± 1,831) P2 got the best output in grains. The corresponding T2 to the dose (30 – 15 – 15) could be kept for the P1. The corresponding T1 to the dose (20 – 10 – 10) could be recommended for the P2 to increase the productivity of corn in the zone of survey.
