ABSTRACT
Rejected lime is a residual by product generated during the calcination of rejected limestone. In the present study, the aim is to utilize rejected lime as a soil conditioner and evaluate its effectiveness for the growth of the green gram (Vigna radiata) plant. The soil samples were collected from eastern (16.9931° N, 54.7028° E) and western (16.7118° N, 53.1857° E) mountainous ranges of Dhofar Governorate, Oman. Soil and rejected lime samples were evaluated for pH, electrical conductivity, particle size, moisture. In addition, the collected soil samples were mixed with various proportions of rejected lime (10 to 50% of rejected lime in soil-rejected lime mixture with fixed 5 g of soil) and tested for pH, electrical conductivity, and cation exchange capacity. An optimal combination of soil and rejected lime from each mountain was selected to grow the green gram plant for 28 days. The western mountainous range of Dhofar Governorate showed better growth with 4 plants, and length of the stem, root, and plant as 14.2, 2.1 and 16.3 cm, respectively. Thus, it is be concluded that rejected lime could be a potential soil conditioner for plant growth.
