GREEN FODDER YIELD AND QUALITY OF BARLEY (HORDEUM VULGARE L.) AS AFFECTED BY LEVELS OF NITROGEN

SUMMARY A field study was conducted during rabi season of 2012-13 at Research Farm of College of Agriculture, S. K. Rajasthan Agricultural University, Bikaner. Treatments comprised six levels of nitrogen (20, 30, 40, 45, 60 and 80 kg/ha) with four replications in randomized block design. Response in terms of green fodder yield (GFY) obtained per kg of nitrogen applied (PFPn) sharply declined beyond 30 kg N/ha. In terms of GFY, significant response of basal application of nitrogen was noticed up to 40 kg N/ha (124.25 q/ha). In case of DMY, significant positive response was noticed only up to 30 kg N/ha. NDF, ADF and lignin content remained unaffected due to nitrogen application. The crude fat and mineral contents exhibited significant and positive response up to 30 kg N/ha. Crude protein content tended to increase up to 80 kg N/ha. Beyond 30 kg N/ha only 60 and 80 kg N/ha produced significant and positive effect on CP content.
