e1“All traits of maize under study (plant height, No. of green leaves/plant and leaf area index at 100 days from planting, No. of ears/fed., ear length, ear weight, weight of kernels/ear, 100-kernel weight, kernels shelling %, biological yield/fed., grain yield/fed., stover yield/fed., harvest index %, kernels nitrogen uptake/fed., kernels protein yield/fed., leaf and kernel nitrogen contents, zinc, manganese and iron contents of maize leaves in the two seasons.) showed significantly increased by increasing nitrogen fertilizer rates, except, mid tasseling and silking dates significantly decreased with increasing nitrogenrates in the both seasons.”

Other claims from this paper (15)
- Intervention effect Plant height, number of green leaves per plant and leaf area index at 100 days increased with nitrogen fertilizer rates.
- Intervention effect Weight of kernels per ear, 100-kernel weight and kernel shelling percentage increased with nitrogen fertilizer rates.
- Intervention effect Biological, grain and stover yields per feddan increased with nitrogen fertilizer rates.
- Intervention effect Harvest index, kernel nitrogen uptake and kernel protein yield increased with nitrogen fertilizer rates.
- Intervention effect Leaf and kernel nitrogen contents increased with nitrogen fertilizer rates.
- Intervention effect Zinc, manganese and iron contents of maize leaves increased with nitrogen fertilizer rates.
- Intervention effect Mid tasseling and silking dates decreased with increasing nitrogen fertilizer rates.
- Intervention effect Application of 130 kg N per feddan gave the maximum values of the maize traits.
- Intervention effect The micronutrient foliar spray with mixed Zn + Mn + Fe was the most effective treatment for growth, yield and yield components of maize.
- Intervention effect Foliar spray with singly Zn gave the highest leaf zinc content in maize.
- Intervention effect Foliar spray with singly Mn gave the highest leaf manganese content in maize.
- Intervention effect Foliar spray with singly Fe gave the highest leaf iron content in maize.
- Intervention effect The combination of 130 kg N per feddan with mixed Zn + Mn + Fe foliar spray gave the greatest values of plant height, green leaves per plant and leaf area index.
- Intervention effect The combination of 130 kg N per feddan with mixed Zn + Mn + Fe foliar spray gave the greatest values of kernel number, ear and kernel weight, biological yield and grain yield.
- Recommendation Fertilization of maize with 130 kg N per feddan plus mixed Zn + Mn + Fe foliar spray is recommended to maximize grain yield.
