Effect of Corm and Soil Treatments with Organic Liquid Formulations on Performance of Elephant Foot Yam in Jharkhand, India

Abstract

A field experiment was carried out at the farm of Divyayan Krishi Vigyan Kendra, Ramakrishna Mission Ashrama, Morabadi, Ranchi during kharif season of 2022 with 10 treatments (T1: control or no treatment, T2:  Corm treatment with Beej Sanjeevani, T3:  Corm treatment with Beejamrit, T4: Soil application of Jiwamrit, T5: Soil application of Panchagavya, T6: Soil application of Jiwamrit + Panchagavya, T7: Corm treatment with Beej Sanjeevani + soil application of Jiwamrit, T8: Corm treatment with Beej Sanjeevani + soil application of Panchagavya, T9: Corm treatment with Beejamrit + soil application of Jiwamrit, T10: Corm treatment with Beejamrit + soil application of Panchagavya) placed in three times replicated randomized block design to study the growth, yield and production economics of elephant foot yam under uses of organic corm and soil treatments. Results revealed that corm treatment with Beejamrit + soil application of Jiwamrit resulted in higher growth attributes, corm length (23.3 cm), dimeter (26.9 cm) and yield (32.8 t/ha). This corm + soil treatment also recorded the highest gross return (INR.2,62,400/ha), net return (INR.1,69,189/ha) and B:C (2.82). It also increased soil microbial population dynamics especially total bacteria (69.7 CFU × 106/g of soil).
