(Figure , 4 and Table ). After the second application, fourteen days later, the percentage increase in average plant height, compared to the previous application, was in the order B > E > C > A > D, with the highest average height at 26.20% and the lowest at 5.80%. When referencing maize D (control), the percentage increase followed the order B > C > A > E, with the highest average height at 71.80% and the lowest at 17.20% which is potassium ratio present in the samples (Table , Figure and). Maize A exhibited stunted growth, yellowing, and leaf burning four days after the second application, which is due to the pH of fertilizer B (table ). Additionally, maize C displayed a dark green leaf colouration, indicating higher chlorophyll content, compared to the rest, following the order C > B > A > E > D, which is due to the total nitrogen content present in all the sample as shown in table . Nitrogen is an essential nutrient for the growth and development of maize plants. It constitutes a vital component of chlorophyll, the pigment responsible for photosynthesis, as well as amino acids, which serve as the building blocks of proteins. 39 After the third application, fourteen days later, the percentage increase in average plant height, compared to the previous application, was in the order A > B > E > D > C. The highest average height recorded was 79.50%, and the lowest was 40.39%. When referencing sample D (control), the percentage increase followed the order A > B > C > E, with the highest average height at 68.11% and the lowest at 19.55% (Table , Figure and). Maize A showed a significantly higher growth percentage compared to maize B, maize C, and maize E when compared to maize D. Its leaves also exhibited an intense dark green coloration, similar to that of maize C. This is attributed to the addition of thiourea as an additional source of nitrogen in the final formulation for maize A as compared to the rabbit manure E. Studies have shown that nitrogen content in typically ranges from 1% to 3% in mature compost. This finding aligns with the results of, who demonstrated that sugarcane waste straw biochar significantly improved okra plant growth and yield parameters when compared to control, farm yard manure, and NPK. It is also consistent with, who reported that the yield of crops using compost from olive mill waste was comparable to that of chemical fertilizers, with no significant difference observed in soil content between the two.
