Guar is a kharif (monsoon) crop. In a typical year it is sown when the monsoon rains arrive, roughly June to July, and harvested roughly October to November. New-crop seed starts reaching markets in autumn, and arrivals usually build through the following weeks.
Timing shifts with the rains. A late or weak monsoon delays sowing and can cut the crop, so confirm the picture for the specific year with your supplier.
The crop calendar in a typical year
These windows are approximate and vary by district and year. The wider pattern for monsoon crops is described in what harvest seasons apply to rabi and kharif crops.
- June to July: sowing after the first good monsoon rains in Rajasthan, Gujarat and Haryana.
- July to September: growth, flowering and pod set. Rainfall in this period decides much of the yield.
- October to November: harvest and threshing, roughly, depending on sowing date and area.
- October onwards: new-crop arrivals at APMC markets in the growing districts.
- Winter: processors buy and store seed, and new-crop powder becomes widely available.
Why the monsoon matters so much
Most guar is rain-fed and grown on sandy soils that hold little water. The crop tolerates drought better than many others, which is why farmers plant it in dry areas. But yield and seed quality still depend on rain at the right time. Too little rain cuts yield. Heavy or unseasonal rain at harvest can discolour seed and cause problems in storage.
Farmers also decide how much guar to plant based on recent prices and on the alternatives, such as pulses, groundnut or cotton. A high guar price one year often brings a larger sown area the next.
What the season means for buying
Guar is processed year round from stored seed, so you can buy powder in any month. What changes is price and the room you have to negotiate. For general timing, see the best time of year to book agri contracts in India.
- Late summer: watch monsoon progress and sowing reports. Prices can move on weather news alone.
- Harvest and arrivals: supply is clearest and choice of seed lots is widest.
- Winter and spring: processors work through stocks. Prices react to oilfield demand and crop estimates.
- Before the next monsoon: carry-over stocks decide how tight the market feels.
Crop year and quality
Seed from a stressed season can give lower gum yield and different viscosity. Ask suppliers which crop year your lot comes from, and test new-crop samples before you commit to a full season's volume. Keep a retained sample from your last approved lot so you can compare like with like.
