Abstract:
A field experiment was carried out, with a view to study the Response of Greater Yam (Dioscorea alata L.) to different growing conditions at Vegetable Research Scheme, Regional Horticultural Research Station of the Navsari Agricultural University, Navsari, Gujarat, India during 2015-2016 and 2016-2017. The experiment was conducted in Large Plot; analysis as CRD with factorial concept (FCRD) with three repetitions which included three growing conditions (G_1: Naturally Ventilated Poly house, G_2: Net house and G_3: Open field), three planting distance (D₁: 60 cm x 60 cm, D_2: 60 cm x 45 cm and D₃: 90 cm x 90 cm) and two varieties (V₁: Round type and V_2: Long type). The results revealed that higher values for growth characters namely, vine length at harvest and fresh weight tuber, yield characters viz., tuber girth, tuber length and tuber yield and quality characters like carbohydrate, starch and protein were found significant in Naturally Ventilated Poly house, Closer spacing 60 cm x 45 cm and Long type variety (V₁). Among from different interaction treatments G x D were found significant in growth, yield and quality characters.
