Abstract: This experiment was conducted in the station of Horticulture and Forestry, Al-Mahaweel, Babylon governmentduring the period from season 2021, to study the effect of adding poultry waste (0, 5, 10, and 15 ton/h) and spraying growgreen foliar fertilization (0, 3, 6, and 9 gm/L) on seedling growth and availability, as well as uptake of NPK. An experiment withthree replications using a Complete randomized design (CRD). The following is one possible way to summarize the results:The level 15 ton/h offered a considerably high rise in available NPK and uptake by seedling, in addition to seedling height, thenumber of leaves, and leaf area. However, the level 9 gm/l of grow green gave a significantly high increase in all of the qualitiesmentioned above.

Abstract A field experiment was conducted in Al-Mahaweel district, Al-Imam hand, Al-Birawi region, in a soil with a texture of Silty Clay Loam classified into the major typic torrifluvent group according to the randomized complete block design (RCBD), Split plot experiment with three replications, to study the effect of irrigation water quality, organic matter, and the level of zinc nano-fertilizer applied as a spray on plants, and the effect of their interaction on some soil properties, which include EC, PH, SAR, and soil organic matter, and growth traits such as plant height and percentage of chlorophyll in sunflower leaves, the experiment included three variables: irrigation with four types of different electrical conductivity 2, 4, 6, and 8 dSiemens, three levels of organic fertilizer (zero) without addition, 20 tons.ha-1 of cow manure and sheep manure, and three levels of zinc nanofertilizer 0, 1.5, and 3 g.L-1, the organic matter showed a significant increase in the chlorophyll content of the leaves of the sunflower plant, while spraying nanoparticles of zinc did not affect the SAR, pH and OM, The effect of the interaction between the three factors was significant on soil properties.
