Abstract:
The experiment was carried out for season of (2018-2017)at the Demonstration Farm of Collage of Agricultural Studies Sudan University of Science and Technology at 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 in a randomized complete block design (RCBD) with three replications. Hudiba -1, cultivar was grown under two levels of nitrogen in (urea 45%) N1 (40kgN/ Ha) and N2 (80 kg N /ha) with five plant powder of the following plants 40kg/ ha): Neem seeds (Azadirachtaindica L., Mint leaves (Menthaspicata L.) Moringa leaves (Moringa olifera L.) and Shaih seeds (Artimissiaannua L.) with control. The treatment 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). 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 kg fertilization was generally better than 40 kg, fertilization. However, different plant products increased nitrogen uptake and utilization by maize plant. Neem at 80 kg nitrogen had the highest maize yield.
