GCH-4

Released in 1986 and still grown across Gujarat for its dual irrigated/rainfed suitability and its tolerance to jassid and wilt. Not yet individually researched for a detail page.

About this variety

GCH-4 is a castor hybrid, corroborated across independent secondary sources as released in 1986 and recommended for both irrigated and rainfed cultivation, with tolerance to jassid (leafhopper) and wilt — matching this record's own top-level fields closely. A directly-fetched ICAR wilt-screening study abstract independently confirms GCH-4 among SDAU's released, wilt-resistant hybrids (listed alongside GCH-5, GCH-7, GCH-8, GCH-9 and GCH-10). No source checked this phase gave its exact parentage cross or a specific yield figure beyond the general rainfed/irrigated range already in this record.

Yield & maturity

Maturity period

200–220 days (staggered picking)

Expected yield

Around 15–18 q/ha under normal rainfed management

Actual yield depends on sowing time, soil, irrigation, weather, seed quality and crop management.

Pest & disease considerations

Advantages & considerations

Why farmers may choose it

  • Dual suitability for both irrigated and rainfed cultivation, unlike hybrids bred for only one management style
  • Combined jassid and wilt tolerance in one long-established, well-corroborated hybrid

Things to consider

  • No source checked this phase gave GCH-4's exact parentage cross, or a yield figure more specific than the general rainfed range already in this record's own yieldPotential field — this record's existing figures were not contradicted, just not independently improved on

Frequently asked questions

When was GCH-4 castor released?

1986, corroborated across independent secondary sources.

Is GCH-4 suitable for rainfed or irrigated fields?

Both — it is recommended for both irrigated and rainfed cultivation, corroborated across independent secondary sources.

What is GCH-4 resistant to?

Jassid (leafhopper) and wilt, matching this record's own field; independently confirmed as one of SDAU's released wilt-resistant hybrids by a directly-fetched ICAR study.

Who developed GCH-4?

Sardarkrushinagar Dantiwada Agricultural University (SDAU), Gujarat — inferred from its listing alongside other SDAU-developed GCH-series hybrids (GCH-5, GCH-7, GCH-8, GCH-9, GCH-10) in a directly-fetched ICAR study; not independently confirmed by a GCH-4-specific primary source this phase.

What yield does GCH-4 give?

Around 15-18 q/ha under normal rainfed management, per this record's own field — no source checked this phase gave an independent, more specific figure.
