A survey was conducted to study the mineral composition of green and dry roughage in Gurgaon district of Haryana state. From each of the four blocks, three villages were randomly selected. To have a systematic and planned study, all the blocks were included in the survey. From each block, three villages were randomly selected to have a fairly representative sample. From each village, four categories of farmers i.e. landless, small (having up to five acres of irrigated land), medium (five to ten acres of irrigated land) and large (more than ten acres of irrigated land) and having dairy animals were purposefully selected. In each village, five families under each category were interrogated on the prescribed Performa for this study, thus, making a total of 240 families. Sorghum and wheat straw were the main green and dry fodder crops adopted in the area during Kharif season. Among the concentrate feeds, wheat dalia and cottonseed cake were found to be most popular. Results showed that Ca and P concentrations of sorghum are above than critical level i.e., 0.30% and 0.25% respectively. In sorghum Zn was highly deficient in all samples as its level was below than critical level (30 ppm). In case of Cu considering 8ppm as critical limit, none of the samples were deficient in the district. The average Fe content of sorghum in district was 179.09 ppm. Considering 50 ppm as critical limit, none of the samples were deficient in the district. Mn content of some samples of sorghum was below critical value (40 ppm). Few samples of straw in Ca content were below critical limit (0.30%). The P concentration of straw was below critical limit (0.25%). Samples of straw were highly deficient of P. Considering 8ppm as critical limit; half of the samples of straw were deficient in Cu. Samples were deficient of Zn as its level was below critical limit (30 ppm). None of the samples of straw were deficient in Fe in the district. The average Mn concentration of straw ranged from 43.58 ppm (Sohna) to 44.01 ppm (Farrukhnagar). Some samples were below critical value (40 ppm). Thus we can conclude from this study that Ca, P, Cu, Fe are above critical level, Zn highly deficient and Cu moderately deficient in sorghum. Whereas straw was deficient in Ca, P and Zn, moderately deficient in Cu and Mn and no deficiency was found in Fe content.
