Abstract:
The experiment titled "Standardization of plant densities and fertilizers in Chinese potato (Coleus rotundifolius L.)" was carried out during the Rabi season of the year 2022-2023 at the College of Horticulture, Venkataramannagudem, Dr. Y. S. R. Horticultural University. The study involved twelve treatment combinations of four plant densities: 45 cm × 10 cm (S₁), 45 cm × 20 cm (S₂), 45 cm × 30 cm (S3), and 45 cm × 40 cm (S₄). The experimental design used was a Randomized Block Design and was replicated three times. The results indicated that Chinese potato planted at a plant density of 45 cm × 30 cm (S₃) demonstrated superior performance in various vegetative viz., vine length, number of leaves, plant spread and number of nodes and yield parameters viz., days to tuber harvest, number of tubers, tuber yield per plant
