abstract
The present investigation entitled “Effect of different growing media and planting methods on growth and yield of sweet potato variety Indira Madhur under grow bag condition” was carried out during 2022-23 at premise (lobby) of Department of Vegetable Science, under Pt. Kishori Lal Shukla College of Horticulture and Research Station, Rajnandgaon, Chhattisgarh. The research was framed in Factorial Completely Randomized Design (FCRD) with 12 treatments which were replicated thrice. There were 2 factors, first factor with 4 levels of different growing media viz, M₁ (Black soil), M₂ (Black soil: Vermicompost: Sand: Paddy husk 1:1:1:1), M₃ (Black soil: Vermicompost: Sand: Cocopeat 1:1:1:1), M₄ (Black soil: Vermicompost: Red Soil: Cut paddy straw 1:1:1:1) and second factor with 3 levels of level of planting method viz V₁ (Vertical planting method), V₂ (Horizontal planting method) and V₃ (Folded planting method). The experiment was exempted to find out the treatment combination M₂V₂ was found superior for growth and yield parameters viz maximum vine length (162.22 cm), number of branches per plant (12.39), number of leaves per plant (263.13), at 120 days after planting respectively, fresh weight of foliage per plant (567.83 g), dry weight of foliage per plant (103.97 g), number of tubers per plant (9.37), length of tuber (15.47 cm), girth of tuber (5.30 cm), marketable tuber yield per plant (464.67 g), unmarketable tuber yield per plant (97.33 g), total tuber yield per plant (562 g) while maximum harvest index (46.87%) was recorded in treatment combination M₃V₁.
