Agronomic Effi ciency indicated the grain yield production potential of variety in response to the applied nutrients. Field experiment was conducted at the research Farm of Bako National Maze Research Center Western Ethiopia during 2020/2021 in order to investigate the nitrogen response and agronomic effi ciency of various maize genotypes. Ten maize varieties were tested under two level of nitrogen (N1 = 0 kg/ha and N2 = 184 kg/ha) in factorial arrangement with three replications. Each variety was planted in uniform spacing of 75x30 cm. Then response of each variety for the applied nitrogen were evaluated. Agronomic effi ciency of Nitrogen Fertilizer associated with grain yield of various commercial maize varieties was calculated using average grain yield and applied nitrogen to indentify the agronomic effi ciency of each maize varieties. Based on calculation result maize hybrid BH661 showed the highest agronomic effi ciency (35.42), where as Gibe3 showed the lowest value (4.68) compared to others tested varieties. This result indicated that Gibe3 respond poorly for the applied nitrogen where as Hybrid BH 661 highly responded for the increasing applied N input. The result has indicated the need of specifi c recommendation for nutrient scarce area, that lack nitrogen or for farmers who lacks money to buy nitrogen fertilizer should be used Gibe3 to get better yield. On other hand in optimum or high nitrogen available condition the hybrids which have high agronomic effi ciency should be sown to boost maize grain yield but with taking into account the optimum rain fall and agro ecology of each variety.

Depletion of nitrogen and phosphorus in terraced hilly areas of Rwanda has lowered maize (Zea mays L.) production. Trials were carried out in 2017 and 2018 in four-year-old-terraced Lixisols and Acrisols of medium and high altitudes to determine effect of nitrogen and phosphorus fertilizer application rates on maize yields. A factorial arrangement of four levels of nitrogen (0, 60, 120 and 180 kg N ha-1) and phosphorus (0, 40, 80 and 120 kg P2O5 ha-1) in a randomized complete block design with 3 replications, was used. Results showed that combinations of 120 - 180 kg N ha-1 and 80 - 120 kg P2O5 ha-1 resulted in significantly (P less than 0.05) higher increases in plant height (45 – 60 % and 56 – 70 % over the control), stem collar diameter (63 – 74 % and 43 % over the control) and grain yields (3 times over the control; i.e. 6.40 – 6.46 t ha-1 and 6.02 - 6.12 t ha-1) in medium and high altitude sites. The optimum fertilizer rates are 176.6 kg N ha-1 and 96.2 kg P2O5 ha-1 in terraced Lixisols of medium altitude area. Land use needs to adjust fertilizer application to these optimum rates for enhanced maize yields in this area and other regions with similar agro-ecological characteristics. Further studies on integrated effects of N and P fertilizers are recommended.

“…The tasseling and silking date of maize increased with decreasing in nitrogen rate. The delaying of fl owering date in response N starvation has been previously acknowledged [8,11,19,22], but this research is the fi rst to report the effect of if nitrogen is defi cient. However, there were researchers who reported results opposite to ours.…”

“…Maize is an exhaustive feeder of nutrients; the chemical fertilizer especially nitrogen fertilizer is universally accepted as a key component to high maize yield [11], and if defi ciency occurs at tasseling and silking stages it may lead to virtual crop failure. Application of nitrogen as well as increase in its rate induced earliness of tasseling and silking stages [19][20][21][22]. In contrast to tasseling and silking stages, increasing nitrogen rate application signifi cantly increased number of days to physiological maturity [11,16,21,23].…”

Maize hybrid responds differently to various N rates and plant spacing with changing in grain yield and phenological period to refl ect the respond. A fi eld experiment was conducted at Bako research farm in the year 2017 to determine the response of maize phenology and grain yield for various nitrogen fertilizer rates and plan spacing. The experiment was arranged in a Randomized Complete Block Design in factorial combination with three replications. Three plant spacing i.e. 20cm, 30cm and 40cm, with one row spacing of 75cm and six nitrogen rates i.e. 0kg ha-1 , 23kg ha-1 , 46kg ha-1 , 69kg ha-1 , 92kg ha-1 and 115kg ha-1 were assigned to the experimental plot by factorial combinations. The results showed that reduction in plant spacing and nitrogen starvation resulted delaying to attain 50% tasseling and silking while it speeding up maturity period. Maximum grain yield (10,207.8 kilo gram per hectare) obtained under the narrowest plant spacing (20 centimeters) with application of the highest rate of nitrogen (115 kilo gram nitrogen per hectare). This yield result surpassed by 8.9% compared to the standard check. The experiment indicated an increasing trend of grain yield with increasing N rate and decreasing plant spacing, so further increasing of N rates and reducing plant spacing might further increased the grain yield.
