SUMMARY
Dual purpose barley is an excellent alternate crop for fodder purpose due to its good nutritive value, high palatability and availability of fodder during lean period. Barley crop can be given one cut for green forage and the regenerated crop can be utilized for grain purposes. Thus, barley can serve as supplementary crop for augmenting the green forage demand in the arid/semi-arid areas of northern plains under limited irrigations and in hills under rainfed conditions. The economics goes in favour of dual purpose crop instead of only grain crop in forage scarcity areas of northern plains. The crop can be given one cut at 50-55 DAS in plains and 70-75 DAS in hills for green forage and satisfactory levels of grain yield from the regenerated crop can be utilized as feed or food. On an average, 180-240 and 24-35 q/ha of green fodder and grains, respectively, were produced from dual purpose barley. It responds well to sowing time, fertility levels and time of cutting which vary from location to location. The productivity of green forage as well as grain increased to a significant level by using additional 25 per cent of seed and fertilizer dose as compared to the recommended dose. Seed rate can be enhanced to 125 kg/ha from 100 kg/ha for getting higher productivity of green forage as well as grain and 25 per cent higher fertilizer (75 kg N/ha) should be given after cut for maximising grain productivity. Variety RD 2035 is suitable for dual purpose as it is superior in fodder, grain yield and GEY and to get best performance of dual purpose barley varieties, nitrogen (75 kg N/ha) should be applied in three splits i. e. 1/3 as basal+1/3 immediate after cut+1/3 at next irrigation.
