Abstract:
A field agriculture experiment over two seasons was conducted using zea mays (Fayhaa hybrid) at Sanaaubar Research Station in spring of (2019-2021). The objective was to study the effect of application of levels of tobacco compost wastes (TWC) with mineral fertilizer to a sandy loam soil in vegetative total content of macronutrients content (N-P-K) at the stag of formation of the male inflorescence (VT) and in some of productivity indicators. Different levels of TWC C1=10- C2=20- C3=40 ton/ha and mineral fertilizer were applied mixing with F0=0, F1=25, F2=50 and F3=75% of mineral fertilizer (NPK) according to the recommended dose of the Ministry of agriculture (MOA). Study also includes farmer treatment, which represent 100 % of the recommended mineral fertilizers of MOA in addition of 15ton/h of cow manure. The experiment was used a completely randomized designed with three replicates for each treatment. A significant increase in N, P, K concentrations in shoots at the flowering stage was recorded by increasing of compost levels individual or mixed with mineral fertilizer. There was a positive effect of TWC on ear length, diameter, number of ear rows with increase of TWC level. The highest value of grain yield were in C3F3,CF (8.4-8.1)ton/h respectively.
Keywords: Wast Tobacco Compost, mineral fertilizer, zea mays.
