Abstract Residue quality is a huge determinant of how effective different fertilizers are on soil and crop plants. The aims of this study was to compare the effect of different fertilizer types on soil physical properties, growth and yield of okra {Abelmoschus esculentus (L.) Moench (LD 88-1)} in southwest Nigeria. Field experiments were conducted during […]

Abstract Water is an important factor in plant development. As important as water is, its excess can be dangerous and injurious to seedling; therefore the water requirement of seedlings at nursery level must be determined for effective performance of the plants. This study assessed the water requirement of Dennentia tripetala at nursery level. Sixty seedlings […]

Abstract Vernonia amygdalina Del was grown in soil treated with a mixture of cadmium and zinc in different concentrations (25, 50, 75 and 100 mg/kg) to investigate the effect of the treatments on the growth of V. amygdalina. Identical stem cuttings were collected and sown in buckets filled with 5 kg dry soil. These were […]
