What to do, and when

Dates assume planting around 5 Oct. Change the plan to shift them.

  • 1–3 weeks before — Prepare a fine seedbed: Pre-sowing irrigation on sandy soils.
  • Day 0 — Sow: 1.5–2 kg per acre with phosphorus and sulphur.
  • Days 15–20 — Thin plants: Keep 10–15 cm between plants.
  • Days 30–40 — First irrigation + nitrogen: Before flowering.
  • Months 2–3 — Aphid and stem rot watch: Check shoots weekly in December and January.
  • Months 2–3 — Irrigate at pod filling: Also before a frost forecast.
  • Months 4–5 — Harvest: When 75% of pods turn yellow — later harvest shatters seed.
  • Month 5 — Sell: MSP procurement or oil-mill buyers.

Varieties to consider

Buy certified seed or planting material from an authorised source.

  • RH 725 · RH 749 · RH 761 — CCS HAU releases widely grown in Haryana.
  • Giriraj — ICAR-DRMR variety for timely-sown irrigated fields.

Water

  • One or two irrigations: before flowering and at pod filling.
  • Never let it go short at: Pre-flowering (30–40 days) · Pod filling (60–80 days)
  • A light irrigation before a forecast frost protects flowers and pods.

Nutrition

Sulphur raises oil content — single super phosphate or gypsum supplies it.

  • Dose: Irrigated: about 80 kg N, 40 kg P₂O₅ and 40 kg sulphur per hectare
  • At sowing: all phosphorus and sulphur with half the nitrogen.
  • First irrigation: remaining nitrogen.

Pests and diseases to watch

Agriculture Novel is a knowledge base, not an advisory service. Where a page runs a model it shows the method and the inputs; where it quotes the crop reference, those are planning ranges whose sources are listed — and counted — on the sources page. A number that fits a package of practices still has to fit your field: check it against your own soil test and your local agriculture officer before you spend money on it. © 2026 Agriculture Novel · Kharif · 24,425 guides published
