Optimizing yield and water productivity in summer mung bean (Vigna radiata L.) through crop residue management and irrigation strategies.

A multi-season research trial entitled 'crop residue management effects on yield and water productivity of summer mung bean (Vigna radiata L.) under different irrigation regimes in Indian Punjab' was conducted at Punjab Agricultural University (PAU), Regional Research Station (RRS), Bathinda, during rabi 2020 and 2021. The field experiment was conducted in a split-plot layout with nine treatment combinations and replicated thrice.

Successive addition of rice straw biochar enhances carbon accumulation in soil irrigated with saline or non-saline water.

Biochar has been evaluated globally to improve soil fertility and mitigate climate change. However, the long-term effects of successive biochar application on carbon (C) accumulation in soil irrigated with saline versus non-saline water (canal water) has not been investigated. A field experiment was conducted to study the effects of rice straw biochar addition rates (0, 2, 4, 8 Mg ha) on C storage in soil irrigated with water of different electrical conductivity [EC, dS m]; 0.
