Overview
Jowar or sorghum is a tough, drought-tolerant cereal grown in both kharif and rabi for grain and fodder across Maharashtra, Karnataka, Telangana and Madhya Pradesh. It responds well to balanced fertiliser, but like other dryland crops the response depends on available moisture. Nitrogen is split between sowing and one or two top-dressings, while phosphorus and potash go in at sowing. Hybrids and irrigated rabi jowar take more fertiliser than local rainfed varieties. Zinc shortage is common in the light soils where jowar grows. ICAR and State Agricultural Universities give a clear N:P:K range. Use the doses below as a guide, scale them down for rainfed crops, and always adjust to your Soil Health Card or a fresh soil test and local KVK advice.
Recommended NPK dose for Jowar (Sorghum)
A common ICAR blanket range for jowar is about 70 to 80 kg N, 35 to 40 kg P2O5 and 35 to 40 kg K2O per hectare, which is roughly 28 to 32 kg N, 14 to 16 kg P2O5 and 14 to 16 kg K2O per acre, with hybrids at the higher end. Rainfed local jowar needs less, around 40 to 50 kg N per hectare. In fertiliser terms per hectare a hybrid dose is about 85 to 90 kg DAP plus 120 to 145 kg urea plus 60 to 67 kg MOP, or per acre about 34 to 36 kg DAP plus 48 to 59 kg urea plus 24 to 27 kg MOP. 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. A recommended split is roughly one fourth of the nitrogen at basal, half at about 25 to 30 days after sowing, and the last fourth at about 40 to 45 days after sowing where moisture allows. For simpler practice, give half the nitrogen at sowing and half as a single top-dressing at the active tillering stage, timed with a rain or irrigation. In rainfed fields, hold back the later splits if rains fail.
Organic & bio-fertilizers
Mix 5 to 10 tonnes of well-rotted farmyard manure or compost per hectare into the soil before sowing, about 2 to 4 tonnes per acre, which improves moisture holding in the light soils where jowar grows. Vermicompost at 1.5 to 2.5 tonnes per hectare is a good alternative. Treat seed with Azospirillum and PSB biofertilisers to fix some nitrogen and free up phosphorus, saving part of the chemical dose. Growing jowar in rotation with a pulse and returning crop residue steadily build soil fertility and reduce the fertiliser needed over time.
Micronutrients & deficiency signs
Zinc deficiency is common in jowar on light and calcareous soils. It shows as broad yellowish to whitish bands between the veins of middle leaves, with reddish or purplish tints and stunted plants. Apply about 20 to 25 kg zinc sulphate per hectare, roughly 8 to 10 kg per acre, at sowing where the soil test confirms it, or spray to correct it fast. Iron deficiency, seen as yellow new leaves with green veins, occurs in alkaline soils and is corrected by foliar spray. Sulphur in light soils improves grain and fodder quality.
Tips & cautions
Match fertiliser to moisture, because in rainfed jowar the crop cannot use heavy nitrogen without water. Split nitrogen and time each top-dressing with a rain or irrigation. Prefer neem-coated urea for better efficiency in light soils. Place phosphorus near the seed. Do not overuse urea, as excess in dry fields is lost and can make plants soft and prone to lodging and shoot fly. For fodder jowar, do not over-apply nitrogen close to cutting, as it can raise nitrate levels. Always follow your Soil Health Card.
These are general recommendations. For the exact dose, follow your Soil Health Card / soil test and local KVK, and avoid over-applying urea.
