Abstract: Maize and groundnut are crops that are produced under diverse cropping systems using different manuring methods to improve productivity. The effects of poultry manure and NPK fertilizer on the performance of maize and groundnut in a relay intercropping was investigated in Akure, South Western, Nigeria with geographical coordinates 70 30’ 0” N, 50 14’ 0” E. The 3 x 2 factorial experiment was arranged in a Randomized Complete Block Design (RCBD) with three replications. Factor A (NPK at 200kg/ ha, poultry manure at 5t/ha and no manure (control)) and factor B (Sole maize, sole groundnut and groundnut/maize intercropped at 3 weeks after groundnut establishment) were allocated with balloting method. Parameters of plant height, number of leaves, number of grains/cobs, weight of 100 grains and weight of 1000 grains were subjected to statistical analysis. Results showed that manures (poultry and NPK fertilizer) significantly increased both the growth and yield characters of maize and groundnut, though not significantly different at p<0.05 from each other but both were significantly higher at p<0.05 at all categories of measurements. Also, intercropping maize/groundnut at 3 WAP significantly influenced the growth and yield values of companion crops than sole maize or groundnut. Manure and intercropped systems interacted to increase groundnut/maize yield significantly than control and groundnut/maize, control and sole maize and control/sole groundnut yield. Maize/groundnut relayed at 3 WAP with application of 5t/ha of organic manure is therefore advocated in place of 200kg of fertilizer for farmers in the study area.

Abstract: In many scholars’ investigation, inhibition of bacterial infectious diseases is one feature of organic ligands. However, identifying the right properties of the ligand have a significant role in medicinal applications. Therefore, 1, 10-phenanthroline and adenine are a rigid planar bidentate chelating agent ligand; which have a high stack interaction with the DNA base and have high biological activities. Furtherly, the quantum chemical distributors are also the key condition to get the therapeutic property. Hence in this review, we conduct the calculated quantum chemical distributors and in relating to this, the chemical reactivity and biological activity of ligands also carried out. The calculated energy gap for 1, 10-phenantheroline and adenine is 4.755 eV and 5.350 eV, respectively suggests that 1, 10-phenantheroline has good chemical reactivity and biological activity than adenine. Other calculated quantum chemical parameters namely, electronegativity, electronic chemical potential, global hardness, global softness, global electrophilicity index, and nucleophilicity index values, their chemical properties, and biological properties of the ligands summarized. The result of these parameters is agreed with the experimental values. The in vitro antibacterial activities of the ligands were tested on two G+ Streptococcus pyogenes, Staphylococcus aureus and two G-; Escherichia coli, Klebsiella pneumoniae bacteria and the results showed that, the in vitro antibacterial activity of 1, 10 phenanthroline significantly greater than adenine.
