Effects of foliar spray of Molybdenum Nanoparticles and phosphor fertilizer on production Medical active substances and chemical structure in yellow sweet clover (Melilotus officinalis L.)

Abstract

      Field experiment conducted at two summer season 2020-2021 and 2021-2022 on clay sandy soil in Al-Diwanyia. The experiment was design as Complete Randomized Block Design with three replications arranged for split-pilot design, and Least Significant differences _0.05 the main treatment contend two level of  phosphor [Iam usedTriple Super phosphate because it raised Ph to alkaline of soil and provide good environment to Rhizobium than Single superphosphate which raised acidic of soil and provided good environment to fungi in future experiment ] ( 0 , 20 kg.ha^-1 ) within their four levels of Mo Nanoparticles (MoNPs)( 0 , 10 , 20 , 30) mg.l^-1.  and irrigated every 3 days I took sample of soil before planting to analysis it and to learn physical and chemical properties table 1. Yellow clover Seeds sowing at rate 20 kg. ha^-1(1 cm depth) at 1/4, after 7 months I took a samples to measure. The results showed  all factors and interactions were significant effect and produce three medical active substances Dioxolane ,Ethylamine , Benzaldehyde and protein , carbohydrates ,Fats , total chlorophyll , forage yield and their max values respectively(2.72 , 2.35 , 3.08 , (17.89 , 5.69 , 0.99)%  , 2.88 mg. 2g^-1 , 1.71 T,ha^-1) in interaction 20 kg.ha^-1 and 30 mg.l^-1 while the min values respectively ( 0.02 , 0.02 , 0.02 , (16.19 , 4.92 , 0.85)% , 2.38 mg.2g^-1  and 1.12 T.ha^-1) in the interaction of 0 kg.ha^-1 and 0 mg. l^-1 MoNPs t.
