ABSTRACT

Field experiment was conducted on non-calcareous, zinc deficient clay loam soil (Typic
Ustopept) with rice (variety ADT-45) was the test crop to study the effect of zinc-enriched organic
manures. The treatments were NPK alone, NPK +200 kg FYM without enrichment, NPK + 200
kg FYM enriched with different levels of Zn (1.25 kg, 2.50 kg and 5.0 kg Zn ha-1) , NPK + cow
dung without enrichment, NPK + 200 kg cow dung enriched with different levels of Zn . The
result of the field experiment revealed that recommended dose of NPK +200 kg FYM enriched
with 5.0 kg zinc increased the grain (5430 kg ha-1) and straw (7075 kg ha-1) yields which was due
to increased availability of zinc in soil. Uptake of nitrogen, phosphorus, potassium and zinc were
found uniform trend with the highest uptake in the plots receiving recommended fertilizers along
with 200 kg of FYM or cow dung enriched with 2.5 kg or 5.0 kg Zn as compared to control.
