Abstract: Soil puddling is considered favorable for rice but unfavorable for post-rice upland crops.The deleterious effects of puddling in post-rice mungbean and management of puddled soil have not been adequately addressed earlier in Bangladesh.This research work was conducted to amend differential puddled soil through organic amendments for improved post-rice mungbean production.The treatments were puddling by four passes, puddling by eight passes, and non-puddling with three organic amendments i.e. control, crop residue, and cow dung.Puddling generally increased bulk density of soil under moisture deficit condition.Puddling had no significant effect on soil pH, total-N, available-P, exchangeable-K, and organic-C.Application of cow dung in the puddle soil increased the amount of N (75.0%),P (35.5%),K (13.3%), and organic-C (38.8%) compared to control.Puddling (eight passes) impaired root growth resulting reduced total dry matter production by 15.6% over non-puddling condition.Cow dung management in differential puddling intensity gave higher root (0.13 g plant -1 ) and total dry matter (1.16 g plant -1 ) production of mungbean than without amendment at 60 days after seedling.Puddling intensity adversely affected the number of pods plant -1 , thousand-seed weight and seed yield.Cow dung application gave significantly higher number of pods, seeds pod -1 and thousand-seed weight.The mungbean seed yield achieved through cow dung incorporation (8.74 g plant -1 ) was better than crop residue (7.38 g plant -1 ) and control (7.34 g plant -1 ).The adverse effects of puddling intensity on soil strength and bulk density and succeeding plant growth and seed yield of mungbean were highly remarkable.Cow dung management indicated a positive response on the improvement of soil properties and mungbean seed yield.
