EFFECT OF NITROGEN, ZINC AND IRON ON THE CELL-WALL COMPONENTS OF BN 2 GRASS

Abstract

Total cell-wall constituents (CWC) of bajra-napier hybrid, BN 2 grass decreased significantly with each increment of fertilizer N. With addition of N, the value decreased from 64.77 to 62.17 per cent at 150 Kg N/ha. The treatment with 5.0 Kg ZnSO./ha recorded the lowest cell-wall components. Successive reduction in lignin due to N addition was noticed. A progressive decrease in silica from 5.794 to 5.130 per cent was noticed at 150 Kg N/ha. The results of the present study indicated that by proper N management it is not only possible to enhance the yield but also improve the quality of fodder by decreased cell-wall constituents
