This pot culture experiment aimed to investigate the impact of different irrigation intervals on root and shoot length in Raphanus sativus var. Pusa chetki. The study involved using pots filled with air-dried garden soil, with each pot containing 20 seeds of the specific cultivar. The irrigation intervals tested included 24, 48, 72, and 96 hours, along with a waterlogged condition. After a growth period of 45 days, the shoot and root lengths were measured and subjected to statistical analysis. The findings revealed significant differences in shoot and root lengths between the control group and the various irrigation intervals. The waterlogged treatment resulted in unsuccessful seed germination and subsequent plant mortality. Longer irrigation intervals led to reduced shoot and root growth compared to the control. Additionally, the control group exhibited a higher root length compared to shoot length, whereas plants subjected to irrigation intervals showed the opposite trend. This study reaffirmed that the most favourable results in terms of shoot and root lengths were achieved with a 24-hour irrigation interval (control), while longer intervals yielded inferior outcomes. These findings align with previous research highlighting the negative effects of waterlogging, including decreased respiration rate, impaired water and mineral uptake, and altered hormonal activities in different plant species. Understanding the impact of irrigation intervals on shoot length and root length can inform agricultural practices and optimize crop growth and development.
