Overview
Barley is a hardy rabi cereal grown for grain, feed and malt, mainly in Rajasthan, Uttar Pradesh, Madhya Pradesh and Haryana, and it tolerates drought and salinity better than wheat. It needs less fertiliser than wheat and responds well to a modest, balanced dose. Nitrogen is split between sowing and a top-dressing at the first irrigation, while phosphorus and potash go in at sowing. Malt barley in particular should not get excess nitrogen, as high protein lowers malting quality. Light and salt-affected barley soils may need zinc. ICAR and the Indian Institute of Wheat and Barley Research give a clear N:P:K range for irrigated and rainfed crops. Use the doses below as a guide and always adjust to your Soil Health Card or a fresh soil test and local KVK.
Recommended NPK dose for Barley
A common ICAR range for irrigated barley is about 60 kg N, 30 kg P2O5 and 20 kg K2O per hectare, which is roughly 24 kg N, 12 kg P2O5 and 8 kg K2O per acre. Rainfed barley needs less, around 40 kg N, 20 kg P2O5 and 20 kg K2O per hectare. In fertiliser terms an irrigated dose per hectare is about 65 kg DAP plus 100 to 110 kg urea plus 33 kg MOP, or per acre about 26 kg DAP plus 40 to 45 kg urea plus 13 kg MOP. Malt barley should stay at the lower nitrogen end to protect malting quality. Reduce urea where DAP supplies part of the nitrogen. These are general ranges only. Always adjust to your Soil Health Card or a fresh soil test and confirm with your local KVK.
Application schedule
Apply full phosphorus, full potash and about half the nitrogen as basal at sowing, placed near the seed. Give the remaining nitrogen as a top-dressing at the first irrigation, about 25 to 30 days after sowing at the tillering stage. In rainfed barley, apply most or all of the nitrogen as basal because a later top-dressing may not get enough moisture to work. Do not delay nitrogen to late stages, especially in malt barley, as late nitrogen raises grain protein and lowers malting grade.
Organic & bio-fertilizers
Mix 8 to 10 tonnes of well-rotted farmyard manure or compost per hectare into the soil before sowing, about 3 to 4 tonnes per acre, which helps light and salt-affected soils hold moisture. Vermicompost at 2 to 2.5 tonnes per hectare is a good alternative. A green manure crop before barley improves nitrogen and structure. Treat seed with Azotobacter and PSB biofertilisers to fix nitrogen and free up phosphorus, saving part of the chemical dose. Because barley tolerates poorer soils, steady organic manuring lets you grow it well with low fertiliser cost.
Micronutrients & deficiency signs
Barley is fairly tolerant but can show zinc deficiency on sandy, calcareous and salt-affected soils. It appears as pale yellow to whitish patches between the veins of middle leaves with stunted plants. Where the soil test confirms it, apply about 25 kg zinc sulphate per hectare at sowing, roughly 10 kg per acre. Sulphur deficiency on light soils causes overall yellowing of young leaves and is corrected with gypsum or single super phosphate. Iron deficiency, seen as yellow new leaves with green veins, occurs on alkaline soils and is best corrected by a foliar spray.
Tips & cautions
Do not over-apply nitrogen, especially for malt barley, as excess raises grain protein, lowers malting grade and causes lodging. Split nitrogen into a basal and one top-dressing at the first irrigation. Prefer neem-coated urea for better efficiency. Place phosphorus near the seed rather than broadcasting. Barley uses water and nutrients efficiently, so a modest balanced dose usually gives the best return. Combine farmyard manure and biofertilisers to cut chemical fertiliser, and always follow your Soil Health Card and KVK advice.
These are general recommendations. For the exact dose, follow your Soil Health Card / soil test and local KVK, and avoid over-applying urea.
