RESPONSE OF COMMON BEAN TO RHIZOBIUM INONCULATION AND CHELATING NANO NPK FERTIGATION UNDER DRIP IRRIGATION

Field experiment conducted at winter season 2022-2023 on clay sandy soil in Al-Diwanyia. The experiment was design as Randomized Complete Block Design with three replications arranged for split-pilot design, the main treatment included two groups inoculation and non-inoculation within each group four levels of Nano NPK (0, 1, 2, 3) g.L-1 added in two steps (20 and 50) day of plant growth. A sample was taken of soil (30 cm depth) to analysis it and to know its physical and chemical properties. Table (1) phouslus voulgares L were sowing at a rate 25 kg.ha-1 [40 cm between plants (30 cm depth)] at 1/9, after 7 months a sample was taken to measure. The results showed all factors and interactions were significant effect and increased all growth features (plant content of protein, carbohydrates and fats, Dibenzyloxynitrobenzene, Benzoylpentanoic acid, Valylvaline, Grain yield) max values respectively (30.24, 58, 2.637)%, 3.09 2.92, 1.89, 6.86 T.ha-1) come from interaction of Rhizobium inoculation and 3 g.l-1 while the lowest values respectively [(22.41, 52.26, 2.19)%, 0.02, 0.02, 0.02, 4.39 T.ha-1] come from interaction of non-Rhizobium inoculation and 0 g.L-1 Nano NPK level.
