Abstract

The North Eastern Hill (NEH) region of India is renowned for its rich biodiversity and predominance of low-input, chemical-free agricultural practices. In this context, the use of organic inputs is crucial for improving soil fertility and enhancing crop productivity. Keeping these aspects in view, a factorial pot experiment was conducted during the wet season of 2024 to evaluate the effect of different organic manures on green gram (Vigna radiata (L.) R. Wilczek var. Pant Moong 6) grown in four dominant soil orders of the NEH region, namely Alfisols, Ultisols, Inceptisols and Entisols. Seven organic manure treatments pig manure, poultry manure, compost, vermicompost, neem cake and farmyard manure (FYM) along with an untreated control were evaluated in a factorial completely randomised design (F-CRD) with three replications. The results revealed that poultry manure significantly enhanced yield attributes of green gram, particularly the number of pods per plant, which translated into a 47.87 % increase in pod yield compared to the control. Irrespective of the compost treatments, green gram performance remained comparable across all soil orders, indicating uniform crop response under organic management. Furthermore, the application of poultry manure and pig manure significantly improved soil available nitrogen, phosphorus and potassium compared to the control, FYM and vermicompost treatments. Overall, the study suggests that poultry manure is a promising organic input for improving green gram yield and soil nutrient status across different soil orders under chemical-free farming systems of the NEH region. However, further validation under field conditions across varied soil types and climatic conditions is recommended.
