Effect of different levels of NPK in the growth and development of Jatropha shrub in displaying Samawa

Several experiments were conducted, for purpose of producing the Jatropha bushes and conduct several tests on them inAlmuthanna province, during the period between Spring 2013 until Autumn 2015. The study focused on the followings:Determine appropriate levels of NPK: to ensure high productivity, fertilizer recommendation to the Jatropha experiment which is carried out in one year age, designed by the completed random sectors and three replications using nitrogen levels ( 0, 100, and 200 kg of N/ha).form of urea (46% N) was applied twice, and the levels ofPhosphorous in form of super phosphate (46% P2O5) was applied once at a rate of 0, 100, and 200 kg of P2O5ha-1. Potassium in form of potassium (50% K2O) was applied once at a rate of (0, and 100, kg of K2O ha-1). The three combinations of these fertilizers showed growth , significant increase in the length and growth , the number of branches , leaf area and the content of chlorophyll in different proportions level.
