Impact of Indigenous Organic Nutrients on Corm Yield and Profitability of Elephant Foot Yam Cultivation in Tribal Belt of South Gujarat: First Report from the State

Abstract

The experiment was carried out for two consecutive years during 2022 and 2023, to study the effects of different solid and liquid organics on yield and economics of elephant foot yam. Indigenous source of organics like mahua cake, gliricidia leaf extract, jeevamrut were used. The experiment was conducted at the Rajendrapur farm, College of Agriculture, Navsari Agricultural University, Waghai, The Dangs. The experiment was laid out in Randomized Block Design with factorial concept (FRBD), which comprised four solid organic treatments namely, S0: Control, S1: 100 % RDN through mahua cake, S2: 100 % RDN through vermicompost and S3: 100 % RDN through farmyard manure with four liquid organic treatments namely, L0: No spray, L1: Jeevamrut @ 2%, L2: NOVEL Organic Liquid Nutrient @ 2 % and L3: Gliricidia leaf extract @ 2%. All the sixteen treatment combinations were repeated thrice. The result revealed that the maximum corm yield (70.93 t ha-1) with high net return (₹. 19,63,017) were recorded by treatment combination S1L1 (100 % RDN through mahua cake and Jeevamrut @ 2 %).
