This study aimed to investigate the effects of nickel on the shoot length and root length of Raphanus sativus var. Pusa chetki through a comprehensive series of pot culture experiments. The experiments were designed to simulate real-world conditions and provide insights into how this heavy metal influences the growth and development of the plant species. To ensure accuracy and consistency, standard-sized pots were utilized, each containing 10 kg of air-dried garden soil with proper drainage. The seeds of Raphanus sativus var. Pusa chetki were sown at equal distances in each pot, and the treatments were replicated three times. The plants were allowed to grow naturally under controlled light and environmental conditions for 45 days, after which shoot length and root length were meticulously recorded. The focus of the study was on nickel, known for its potential impact on plant growth. Nickel sulphate was introduced into the soil at concentrations of 100, 500, 700, and 1000 mg/kg, with thorough mixing to ensure uniform distribution. Additionally, a control group without any heavy metal treatment was maintained for comparison. The results showed that increasing nickel concentrations led to a gradual reduction in both shoot length and root length of Raphanus sativus cv Pusa chetki. Previous research on other heavy metals revealed similar negative effects on essential nutrient uptake and enzyme activity in plants.
