Effect of Nitrogen, Shading and Intercropping on Clitoria Forage Production in Ziziphus based Agroforestry System under Arid Land Conditions of Jeddah
Journal Title: Scientia Agriculturae - Year 2016, Vol 14, Issue 2
Abstract
A field experiment was performed to evaluate clitoria-ziziphus agroforestry system under arid land conditions of Saudi Arabia. Clitoria growth and biomass accumulation (fresh and dry) were tested against three nitrogen levels (0 kg N/ha, 200 kg N/ha and 400 kg N/ha), three planting distance (1 m, 2 m and 4 m) from ziziphus tree in inter cropping and sole plantation at Agricultural Research Station of King Abdulaziz University, located at Hada Al-Sham during the 2013 and 2014 seasons. A split-split plot design was used with three replications. Forage growth rate and biomass accumulation were measured at ten different intervals approximately at a period of 30-45 days. Statistical analysis described significant impact for intercropping, planting distance and nitrogen fertilizer on clitoria growth and biomass accumulation. By increasing the fertilizer dose, a gradual increment on forage growth was recorded and maximum forage production was perceived at 400 kg N/ha. The interaction of 400 kg N/ha, intercropping and 1 m distance produced optimum forage growth (108 cm) while 2 m distance produced maximum biomass accumulation (10.86-4.92 t/ha) as compared to the sole plantation under zero fertilization.
