Nutrient uptake and yield of wheat as influenced by iron and fym application in an alluvial soil

摘要

In a field experiment on light textured soil, the effect of iron and FYM applied alone and in combination was studied on wheat. Application of iron alone upto 10 mg kg~(-1) soil increased significantly the grain and straw yield and also the uptake ofnutrients by the soil crop. Likewise, application of FYM also significantly enhanced the yield and uptake of N. P. K and Fe by the crop. Iron and FYM showed a synergistic interaction effect on the uptake of N. P. K and Fe and ultimately on the grain andstraw production of wheat. Maximum grain and straw yield were obtained in the treatment where Fe was applied @ 10 mg kg~(-1) soil with 40 t ha~(-1) organic matter.
