IMPORTANT POINTS IN COTTON CULTIVATION
- Medium to heavy black cotto soils under rain fed situation and fertile red soils under irrigated or ID conditions are suitable for cotton cultivation.
- Light chalka sandy adnred soils withg no irrigation and ill drained soils are nit suitable for cotton cultivation
- Opotimum time for sowing 2ND fortnight of june july 30
- As precautionary measure for pink bollworm management staggered sowing of cotton should be avoided
- Sowing shoul be done under optimuim soil moisture condition (75mm rainfall in 7-10days interval)
- Green manuring (sunhemp) or incorporation of 4-5ft FYM?acre duringlast ploughing
- Planting of non BT cotton under refugee crop as IRM strategy.
- Intercropping cotton with green or black gram / soyabean /clusterbean/foxtail millet / cow pea in 1:2 or 1:3 along with redgram in 4:1 /6:1/8:1 . sowing of 2 to 4 rows of fodder jowar / maize as border crop
- Soil test base fertilizer application should be done.( RDF: /100-125KG UREA 150190KG SSP +40 50KG MOP/ACRE). Entire SSP hould be applied as basal N&K in 3 4 splits from 20DAS depending on soil moisture.
- Pre emeregence application of pendimethaline @1.3L/ACRE within the 23-36hours of sowing . for control of grassy weeds ,application of quizalofop ethyl @ 400ml/acre and for the control of broad leaf weeds @250ml of pthyrobac sodium (2 to 4 leaf stage)
pest and disease management :
MANAGEMENT OF SUCKING PEST IN COTTON
- Grow sucking pest tolerant / resistant varities/hybrids.
- Seed treatment with imidaclopride 70ws 5.0g/kg or thiemethaxom 70ws 4.0g/kg or imidacloprid 48 FS@ 9.0ml/kg or carbosulfan 25DS @ 40.0g/kg of seed , gives early protection against sucking pests.
- Growing intercrops like mungbean or uradbean or soyabean or clusterbean in 1;2or 1;3 ratio.
- Growing cowpea as bund crop Is advantageous to encourage predacious insects lik coccinellids , syrphids and chrysophids.
- Maize or sorghum or pearl millet grown as barrier crops in theborder prevents spread from neighbouring fields.
- Setting up yellow sticky traps @10 per acre for moniterining whitefly incidence .
- Foliar application of neem oil 3000ppm @3ml/lt or 5% NSKE.
- Need based appolicatioin of insecticide.
