Effect of adding liquid organic fertilizer (IPH0 PLANT) on the vegetative growth and mineral content of the Helwani and Kamali vine varieties, Vitis vinifera L.

Abstract

      The experiment was carried out during the 2022 growing season in the grape orchard of the Department of Horticulture and Landscape Engineering, College of Agriculture, Tikrit University. The experiment included two factors, the first being the Helwani, V1, and Kamali V2 grape varieties, and the second factor was the addition of liquid organic fertilizer (IPH0 PLANT) at three levels (400, 250,0) milliliters. -1 vine, to determine the effect of liquid organic fertilizer on the characteristics of vegetative growth and mineral content. The vines were planted at dimensions of 2 x 4 m. The experiment was designed according to the Plot Design Split system. The experiment included 6 treatments that were randomly distributed in three sectors, as the total number of plants was (36). Karma, the data were analyzed statistically using the SAS program, and the averages were compared according to the least significant difference test (L.S.). D At the 5% probability level, the results showed that adding (400 ml LNR-1) led to a significant increase in the chlorophyll content, the length of the main branch, the diameter of the main branch, the mineral content of NPK.
