Impact of carbon sequestration management techniques on yield and economics of maize in maize-potato-greengram cropping system


Rishabh Singh Chandel, AK Srivastava, Ram Pyare and Arushi Chandel

A field experiment was conducted on sandy loam soils of Students’ Instructional Farm, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur, during kharif 2021-22 and 2022-23 to find out the impact of carbon sequestration management practices on maize yield and economics in the maize-potato-green gram cropping system. A week before to maize seeding, the crop residue from green grams was added to the soil. This may be done either alone or in conjunction with microbial (fungal and bacterial) consortia, organic based products, and 100% RDF (120:60:60) as decomposition accelerators. A two-year study's worth of combined data showed that different approaches to managing carbon sequestration improved maize production and profitability significantly. Among the treatments, the highest biological yield (224.60 cm), grain yield (1604.36 g m-2), stouter yield (4.91), as well as Harvest Index (41.68%) was recorded with the treatment where crop residue incorporation + fungal consortium @ 1 kg ha-1 + bacterial consortium @ 1 kg ha-1 + 100% RDF were applied followed by the application of crop residue incorporation + bacterial consortium each @ 1 kg ha-1 + 100% RDF were applied, both were statistically at par with each other while significantly superior over rest of the treatments. Similar trend was also recorded for gross return, net return, and B: C Ratio during both the years. In order to maximize maize productivity and economics in the maize-potato-green gram cropping system, it is therefore feasible to treat crop residue using microbial consortia incorporated in addition to 100% RDF practice.
