Effect of Bio-FertilizerNano Iron and Chelating Iron on Cayenne Pepper Leaf

Abstract

An experiment was carried out inside the plastic tunnels of the 2019-2020 season to study the effect of three methods of treating Bio- fertilizer  and three levels of both Nano iron and chelated iron on the content of chili leaves of nitrogen, phosphorous, potassium, iron, zinc and manganese, in a factorial experment with a design  RCBD in three Replicates  and the experiment factors included (seed pollination, dipping seedlings, and soil injection with bio fertilizer), (0, 0.75, 1.5 gm. L^-1 of Nano-iron) and (0, 5, 10 gm. L^-1 of chelated iron). The results indicated that: The treatment of nano iron (1.5 gm.L^-1) was significantly higher by giving the highest averages of nitrogen, phosphorous, potassium, iron, zinc and manganese elements absorbed by plant leaves, which amounted to (3.13% ‘0.40%, 2.3%, 110.31 gm.kg^-1, 15.02 gm. kg^-1, 51.38 gm.kg^-1) respectively, while the treatment of chelated iron (10 gm. L^-1) was significantly superior and gave the highest averages for the above elements as (2.95%, 0.38%, 2.09%, 94.86 gm.kg^-1). 13.55 gm. kg^-1, 45.60 gm. kg^-1) respectively, and the treatment of bio fertilizer (injection into the soil) significantly outperformed with the highest averages reaching (2.92%, 0.39%, 2.15%, 96.64 gm. kg^-1, 13.86 gm. kg^-1, 47.10 gm. kg^-1) respectively.
