In Bangladesh, groundnut is the second most oilseed crop and has played a pivotal role in meeting the growing oil requirements in recent years and ensuring nutritional security for a population of over 1.6 million (Miah and Mondal 2017; Shakil 2022 ).
Can biochar and biofertilizer improve groundnut production?
Considering these factors by applying biochar and biofertilizer (rhizobium inoculants) in groundnut production, a novel experiment was conducted for increasing soil fertility, groundnut productivity, and soil carbon stock in Bangladesh’s Charland agroecosystems.
Does groundnut improve soil quality?
Groundnut is cultivated on about 32,000 ha of land, and the total groundnut production is about 47,000 Mt in Bangladesh (Azad et al. 2020 ). Being a legume crop, groundnut improves soil quality by biologically fixing nitrogen without consuming non-renewable energies and disturbing agroecological balance.
