Other claims from this paper (13)
- Intervention effect Combined organic and mineral nitrogen gave the greatest maize yield and yield components.
- Intervention effect Combined organic and mineral nitrogen gave the greatest maize NPK concentration and uptake.
- Association Increasing nitrogen levels raised maize chlorophyll a, b, and total chlorophyll content.
- Association Increasing nitrogen levels raised maize ear length, diameter, and weight.
- Association Increasing nitrogen levels raised maize grain weight per ear, rows per ear, and grains per row.
- Association Increasing nitrogen levels raised maize 100-grain weight and grain yield.
- Intervention effect Nitrogen fertilizer up to 120 kg N/fed. increased maize protein content.
- Intervention effect Applying 120 kg N/fed. increased maize phosphorus concentration and uptake.
- Association Nitrogen levels up to 120 kg N/fed. increased maize oil percentage and oil yield.
- Association Nitrogen levels up to 120 kg N/fed. increased maize grain total carbohydrate percentage.
- Intervention effect Ammonium sulphate with compost at 120 kg N/fed. was the better treatment for maize grain yield and its components.
- Intervention effect Compost combined with inorganic nitrogen was more effective for maize yield than either fertilizer alone.
- Recommendation The authors conclude that organic manure improved maize yield and saved mineral fertilizer.
