EFFECT OF INTEGRATED USE OF FERTILIZERS, ORGANIC MANURES AND MICRONUTRIENTS ON PRODUCTIVITY OF SESAME (SESAMUM INDICUM)

Abstract

An experiment was conducted during 2006 and 2007 on clay loam soil during kharif season under All India Coordinated Research Project on Sesame at Tikamgarh to study the effect of inorganic fertilizer, organic manures and micronutrients on growth, yield and economics of sesame. The seed yield was significantly increased with integrated use of 100% NPK + 2.5 t FYM + ZnSO4 + FeSO4 as compared to inorganic fertilizer alone (13.09 %) or with FYM (16.54 %) or with oil cake (11.45 %). The highest gross return was obtained with the application of 100% NPK + 2.5 t FYM + ZnSO4 + FeSO4 whereas highest net return was obtained under 100% NPK + 2.5 t FYM + FeSO4. The highest productivity and return was obtained through recommended dose of fertilizer alongwith FYM, ZnSO4 and FeSO4 indicated that NPK fertilizers alone did not provide adequate and balanced nutrition to realize the potential of the crop.
