Abstract:
The experiment was carried out for tow season summer and winter of 2016/2017 at the Demonstration Farm of College of Agricultural Studies, Sudan University of Science and Technology ,Shambat, Sudan, to study the Addition of Natural Plant Products for Efficient Nitrogen Uptake in Maize (Zea mays L.) The layout of the experiment was factorial randomized complete block design (RCBD) with three replications. Hudiba -1, cultivar was grown under two levels of nitrogen in (urea 45%) Vi3.N (40kgN/ Ha) and N2 (80 kg N /Ha) with five plant powder each weight 40kg/ha of the following plants 40kg/ Ha): Neem seeds (Azadirachta indica L., Mint leaves (Mentha spicata L.) Moringa leaves (Moringa olifera L.) and Shaih seeds (Artimissia annua L.) with control. The treatments were ten combinations in a randomized as follows: Urea (40 kg N/Ha), Urea (80kgN/ Ha), Urea (40kgN/ Ha+Neem powder),Urea (40kgN/ Ha + Moringa powder), Urea (40kgN/ Ha+ Mint powder), Urea (40 kg N/Ha + Shaih powder), Urea (80kgN/Ha+ Neem powder), Urea (80kgN/Ha+ Moringa powder), Urea (80kgN/Ha +Mint powder) and Urea (80 kg N/Ha +Shaih powder) Six yield compontes were measuared in chuded, number of rows,cob,lengthof cob (cm),number of seeds,row,plant,seed weight (gm)and grain yield(t/ha). The results showed only significant difference in number of row per cob, length of cob, seed per plant and 100 seed weight. The natural products was significant for only number of seeds per row. 80 kgN/Ha fertilization was generally better than 40 kg N/Ha, fertilization. However, different plant products increased nitrogen uptake and utilization by maize plant. Neem at 80 kgN/Ha nitrogen had the highest maize yield(1.8 T/Ha).
