What yield can sugarcane farmers achieve with RainGun irrigation?

Mr. Muthu, our first-ever customer (2003), achieved 84 tons per acre peak yield on his 4-acre sugarcane farm in Salem using a permanent RainGun system. Even at the 7th consecutive cutting without replanting, yield was 48 tons/acre — well above the Tamil Nadu average.

Q: How long does a Thumba RainGun system last?

Mr. Muthu's system installed in 2003 is still operational as of 2026 — over 23 years of continuous service. This longevity is due to our custom motor design and the quality of components used in permanent installations.

Q: Can RainGun support multiple sugarcane cuttings without replanting?

Yes. Mr. Muthu's farm achieved 7 consecutive cuttings of sugarcane (ratoon crops) with consistently high yields from the 1st through 7th cutting. Permanent RainGun irrigation maintains soil moisture to support healthy ratoon crops — reducing the cost and effort of replanting.

Q: What motor size is needed for a 4-acre sugarcane field?

Based on our field study for Mr. Muthu's 4-acre farm, we designed a custom 6HP 6-stage motor for the required pressure and discharge. Motor size depends on field size, terrain, and water source — our team conducts a free field study before recommending a system.

Q: Is permanent RainGun better than drip irrigation for sugarcane?

For sugarcane fields of 4+ acres, permanent RainGun systems offer higher coverage area per unit, lower clogging risk, ability to irrigate and apply liquid fertiliser simultaneously, and simpler operation. Mr. Muthu's 23-year track record confirms the long-term ROI of a well-designed permanent system.

Permanent RainGun system on sugarcane farm, Salem, Tamil Nadu

Our First-Ever RainGun Installation — A 23-Year Success Story

In 2003, Mr. Muthu (S/o A. Thanari) from Salem, Tamil Nadu became Thumba Agro Technologies' very first RainGun customer. He approached us with a clear need: reliable, high-volume irrigation for his 4-acre sugarcane field — a crop that demands consistent water supply at every critical growth stage.

After conducting a detailed field study, our team recommended a Permanent RainGun System as the optimal solution. We then went a step further — we designed and manufactured a custom 6HP 6-stage motor specifically for his field conditions, calibrated to deliver the right pressure and discharge volume to cover all 4 acres uniformly.

The Results — 7 Consecutive Cuttings

The system delivered beyond expectations. Mr. Muthu achieved a peak yield of 84 tons per acre — an outstanding result for sugarcane in Tamil Nadu. More remarkably, he achieved consistently excellent yields across 7 consecutive cuttings without replanting the crop. The RainGun system maintained optimal soil moisture through every ratoon cycle.

Even at the 7th cutting — when most farmers would have long since replanted — his farm still yielded 48 tons per acre. And the system he installed in 2003 continues to work to this day, in its 23rd year of operation.

Frequently Asked Questions

What yield can sugarcane farmers expect with RainGun irrigation?

Mr. Muthu achieved 84 tons per acre peak yield on his 4-acre sugarcane farm in Salem. Even at the 7th consecutive cutting without replanting, yield was 48 tons/acre — significantly above the state average. Results vary by soil type, water quality, and crop management.

How long does a Thumba RainGun system last?

Mr. Muthu's system installed in 2003 is still operational in 2026 — over 23 years. This is due to the quality of our custom motor design, corrosion-resistant components, and the permanent installation approach where pipes and fittings are protected from field damage.

Can RainGun support multiple sugarcane cuttings without replanting?

Yes. Mr. Muthu achieved 7 consecutive cuttings (ratoon crops) with consistently high yields. RainGun irrigation maintains uniform soil moisture levels which is critical for healthy ratoon growth — reducing the cost of replanting and labour over the crop cycle.

What motor size is needed for a 4-acre sugarcane field?

For Mr. Muthu's 4-acre farm in Salem, we designed a custom 6HP 6-stage motor. The right motor depends on field size, elevation, water source depth, and distance from pump to field. Our team conducts a free on-site field study before recommending any system.

Is permanent RainGun better than drip irrigation for sugarcane?

For sugarcane on 4+ acres, permanent RainGun systems offer larger coverage per unit, no drip line clogging risk, ability to apply liquid fertiliser simultaneously, and simpler operation. Mr. Muthu's 23-year ROI record is the best evidence of a permanent system's long-term value.
