A field experiment was conducted to study the response of malt barley (Hordeum vulgare L.) cv. 'BCU 73'to N rates and time of its application at Varanasi, Uttar Pradesh, during the winter seasons of 1999-2001. Application of N significantly increased the number of ears, grainslear and 1,000-grain weight up to 80 kglha. The maximum grain and straw yields, total N uptake and protein content in grain were recorded at 80 kg Nlha. Two split applica- tion of N (113 at sowing and 213 at first irrigation) had higher values of yield components and resulted in signifi- cantly higher grain and straw yields. The total N uptake was also the maximum in this treatment, but protein con- tent was significantly higher in treatment receiving 3 splits of N. The benefit : cost ratio was the highest at 80 kg N1 ha and with 2 split application of N.References
