Abstract

Field experiments were conducted during the year 1992-93 with different levels of basic slag and green leaf manure, using ADT-36 rice as test crop. The results revealed that the application of basic slag at various levels significantly increased the available P, Ca, Mg and Fe content of soil at all the stages of crop growth. Moreover, the efficiency of basic slag in building the soil nutrients status was more, when it was applied along with green leaf manure. Similarly, the uptake of P, Ca, Mg and Fe by rice was also enhanced by the combined addition of basic slag along with green leaf manure. The basic slag addition along with green leaf manure at higher levels proved its efficiency even after the residual crops.
