Description In sorghum and mungbean – lentil cropping system, field experiments were conducted
for three successive years to assess the effect of mung bean residue incorporation on
sorghum and succeeding lentil productivity along with different doses of phosphorus
(P; 0, 30, 60 kg ha−1) applied to these crops. The level of soil fertility was also tested
with or without incorporation of mung bean residue. The interaction of phosphorus to
mungbean residue incorporationwas thus studied in relation to improve crop productivity
with balancing fertilizer requirements through an eco-friendly approach. Sorghum grain
yield increased significantly when 60 kg P2O5 ha−1 was applied and mungbean residue
incorporated. The response was reduced to 30 kg P2O5 ha−1 when mungbean residue
was not incorporated. The succeeding lentil crop responded up to 60 kg P2O5 ha−1 only
when preceding sorghum crop received 0 or 30 kg P2O5 ha−1. Response to applied P2O5
to lentil reduced to 30 kg ha−1 when preceding sorghum crop received 60 kg P2O5 ha−1
and mungbean residue incorporated. Available soil nitrogen, phosphorus, and organic
carbon content increased when mungbean residue was incorporated; however, available
potassium (K) of the soil decreased from its initial value
