Abstract:
The experiment entitled “Effect of organic substances on growth and yield of greater yam (Dioscorea alata L.)” was conducted at Horticultural Research Farm of Pt. Kishori Lal Shukla College of Horticulture and Research Station, Pendri, Rajnandgaon, Indira Gandhi Krishi Vishwavidyalaya Raipur, Chhattisgarh. The Growth and yield parameter like vine girth on base (cm), vine length 23 & 180 dap (m), number of vines per plant, petiole length (cm), tuber yield per plant (kg) and tuber yield (t h^-1) were significantly superior in the treatment T₁₁ (Goat manure @ 1.66 t ha^-1 + Azospirillum@ 5 kg ha^-1 + vesicular Arbuscular Mycorrhizae (VAM) @ 5 kg ha^-1 + paddy straw compost @ 5 t ha^-1). The maximum vine girth on base (0.80 cm) was recorded under treatment T_11. The maximum vine length at 20 DAP (1.30 m) and 180 DAP (9.00 m) were recorded under treatment T_11. The highest number of vines per plant (3.50) was recorded under treatment T_11. The maximum petiole length (9.93cm) was recorded under treatment T_11. The maximum tuber yield per plant (2.03 kg) was recorded under treatment T_11. The maximum tuber yield (25.10 t ha^-1) was recorded under treatment T_11.
