Influence of Chemical, Organic and Biological Fertilizers of Yield and Volatile Oil Production of Anise (Pimpinella anisum, L.) Plant

Abstract

In order to determine the influence of different fertilizers types (chemical, organic and bio fertilization) on anise yield components, volatile oil production and NPK percentages two field experiments were done at a Private Farm named Royale for herbs in El-bawiti Village, El Wahat El Bharia District, Giza Governorate, Egypt through 2018/2019 and 2019/2020 winter seasons. The efficiency of organic fertilization (humic acid and compost) and biological fertilization (nitrobein or/and phosphorein) were compared with standard, commercial rates of N, P and K as chemical fertilizers concern the productivity of anise plant. The obtained results referred to that, the chemical fertilizers rate (N, P2O5 and K2O at 100, 75 and 50 kg/feddan, respectively) produced the highest yield components values (number of umbels and umblets per plant as well as fruit yield per plant and fruit yield per feddan) compared to the other ones under study, in most cases. Also, fertilized anise plants with the chemical fertilizers rate of N, P2O5 and K2O at 120, 100 and 60 kg/feddan, respectively gave the highest values regard N, P and K percentages in fruits compared to the other fertilizers type under study. In the same time, anise plants treated with 20 m3 compost + 2 kg phosphorein + 2 kg nitrobein and chemical fertilization (N100 P75 K50) produced the highest values in volatile oil yield production (volatile oil yield per plant and per feddan) compared to the others types of fertilizers under study in 1st and 2nd seasons, respectively.
