Abstract

• This research is concerned with the investigation of the preparation, and characterization of organic fertilizer from neem leaves, cow dung, and peanut shell. The raw materials were collected from the Yenanchaung Township. The organic fertilizers (OF) were prepared by three different weight ratios of neem leaves, cow dung, and peanut shell (100 kg: 100 kg: 100 kg) for OF-1, (125 kg:75 kg: 100 kg) for OF-2, and (150 kg:50 kg: 100 kg) for OF-3 respectively. The organic fertilizers were prepared by compost heap layer method. Field experiments were conducted in Kyawe-Pone Village, Yenanchaung Township, Magway Region to test the effect of organic fertilizer on the growth of peanuts with three treatments (T-1, T-2, and T-3) and a control. The highest yield of T-3 was 725.58 kg/ha, and the lowest yield of peanut in control was 543.49 kg/ha. In this work, the soil before cultivation and after harvesting was analyzed with regards to soil parameters. After harvesting nitrogen content, available phosphorus, and available potassium were higher in organic fertilizer-treated soil than before cultivation soil to maintain and sustain the soil fertility.
