Gray, Vernonia amygdalina Del. and Inorganic Fertilizer (NPK 15-15-15) on Growth and Development of Maize (Zea mays L.)]]>ChukwukaK.S. OgunsumiA.I. ObiakaraM.C. OjoO.M. UkaU.N. 22014132The effects of decaying leaf litter of T. diversifolia, V. amygdalina as organic fertilizer and inorganic fertilizer (NPK 15-15-15) and their combination effects on the growth and development of maize were studied in a Screen House. Twenty four experimental bags filled with 20 kg of loamy soil were laid out in a completely randomized design with six treatments and four replications for each treatment which include: 250 g of decaying leaves of T. diversifolia as mulch (T1), 250 g of decaying leaves of V. amygdalina (T2), 1.52 g of NPK (inorganic) fertilizer (T3), a mixture of 250 g decaying leaves of T. diversifolia and 1.52 g of NPK (15-15-15) fertilizer (T4), a mixture of V. amygdalina and 1.52 g NPK (15-15-15) fertilizer (T5) and control (T6). Significant growth as well as maize yields were obtained from T3 treated maize groups and this was closely followed by T4 seedlings. The study showed that the decaying leaf litter as organic fertilizer in maize production in a Screen House condition did not give better yield than NPK treatment alone.]]>Achieng, J.O., D.
