Effect of adding different levels of organic fertilizer on the growth of maize plant (Zea mays L.)

Abstract

Pots experiment was conducted to study the effect of sheep manure addition on corn plant Zea mays L. vegetative growth. The study was carried out during the season of 2016/2017, at Sidi Khalifah area east of Benghazi Libya. To achieve the aim of the study, the experiment was laid out in complete randomize design, with four levels of organic matter (sheep manure) (0, 5, 15, 25 Ton/h) for fertilizers. Results revealed that, the application of organic matter (sheep manure) fertilizer significantly increased soil properties, improved soil physical, chemical and fertility properties. It can be concluded that use of 25 ton/h for sheep manure was effective in compared to the other applications, since this experiment was applied under controlled conditions using pots, results need to be validate under the realistic field conditions. However, the findings could be regarded as useful indicator within the study area conditions.
