Cultivation
The 145-160-day duration makes RCH-659 a fit for double-cropping systems (Cotton Double Cropping Systems) in which a rabi maize, jowar, wheat or chickpea crop follows cotton on the same field. Standard package-of-practice fertilisation and weed management apply (Cotton First Dose Fertilizer, Cotton Weed Management). The sturdy semi-erect canopy suits both conventional and intermediate row spacing.
Pest profile
The Bollgard-II stack controls the lepidopteran bollworm complex but not the sucking-pest complex (Sucking Pest Complex Cotton) or non-lepidopteran pests. Pink Bollworm populations resistant to Cry1Ac and Cry2Ab require integrated management including timely sowing (Cotton Delayed Sowing Ipm) and refuge (Refuge In Bag Cotton).
Adoption and use
RCH-659 is one of the widely planted Bt cotton hybrids in the southern peninsular states. Field reports highlight clean bursting that simplifies hand-picking and resilience after moisture and pest stress.
