The time of planting is governed mairly by weather conditions. Spring and autumn planting are two important planting season , suru, preseasonal and adsali.
Sugarcane is tropical crop and thrives best in the regions of 750 to 1200 mm rainfall. Hot humid climate- during groweth period Cool and dry climate- during growth maturity
Deficient rainfall produces a fibrous cane, while heavy rain result in low sugar content in cane.
Germination- for quick and higher germination the daily temperature should be about 20 – 32 0c. Below 10 0c and above 40 0c temperature germination is suppressed humidity above 50%. Optimum temperature for tillering is 26-32 0c. Tillering is increased in bright sunshine with large day length and hot weather favours tillering. Optimum humidity required for this crop is 65-70 %
Optimum temperature for growth is 27-30 0c. Coole and dry climate with less than 50% relative humidity is beneficial for riperning of cane. The minimum temperature of 11 0c is ideal for cane ripening.
Sugarcane can be grown in all types of soil ranging from sandy loam to clay loam. Well drained medium deep to moderately heavy soils (60-120 cm depth) high in organic matter content. It can tolerate moderate acidity and alkalinity (pH 5.5 to 8.50 but soils with slight acidity or with pH 6.0 preferred for higher crop yields. Soil rich in P and Ca good for juice quality. Soil rich in Fe and ca good for sugar recovery.
Sugarcane does not require extremely fine seed bed as required for other cereals . The land should be ploughed crosswise deep upto 25-30 cm followed by clod crushing and 2-3 harrowings are required. 20 CL FYM should be added before 2nd ploughing mix well in the soil by harrowing open the ridges and furrows at distance of 100-120 cm in medium and hevy soils. Length of ridges and furrows should be 50-60 metres. Add remaining ½ dose of manures (20 CL) FYM at the time of planting.
1) Soaking in water
by soaking the sets in ater the fresh weight of seed material is increased by 2 to 4 % which results in better germination. Soak the seed material in water for 12 to 24 hrs . Soaking in water is useful when seed material is stailed.
2) Lime water treatment
If the seed material is of more age and showing dry eye buds. Setts are soaked in lime water for 24 hrs. lime water is prepared by dissolving 500 gm of lime in 180 liter of water. This improves germination of dry eye buds.
3) Mercurial compounds seed treatment
setts are dipped in 100 lit water + 100 gm Bavistin + 300 ml Malathion for 10 minutes.
-
1) heavy soil= dry method on ridges and furrows 2) Light soil= wet method on ridges and furrow 3) Paired row / patta method
Planting time of
Suru sugarcane = 15th December – 15th February
Preseaonal sugarcane = 15th October – 15th November
Adsali sugarcane – 15th July – 15th August
Heavy soil= 120 cm
Light soil= 90-100 cm
Paired row / patta method= 75 to 15 cm or 90 to 180 cm
Approximate seed rate for one eye bud setts = 30,000/ha. Approximate seed rate for Two eye bud setts= 25000/ha. Approximate seed rate for Three eye budded setts = 25000 /ha
Earthing up= sugarcane needs light earthing up to 12-16 weeks after planting. It is done by small iron plough or mannually. (3-3.5 months) Final earthing up should be done 20 24 weeks after planting by iron plough or ridger. Mulching- The cane trash use as mulch to conserve moisture. Detrashing- removal of dried leaves from lower parts of plants called detrashing. Wrapping and propping of sugarcane- to provide mechanical support to the grown up cane plants to prevent lodging and mostly adopted in Andhra Pradesh.Gap filling- 6-8 weeks after planting .

Drip irrigation and flood system of irrigation are used for sugarcane. Suru sugarcane 280 ha.cm and 32 irrigation. Tillering and early growth – 5 cm depth Grand growth = 7.5 cm depth Maturity = 5.6 cm depth Effective root zone= 90 cm Adsali sugarcane – 415 ha cm and 38 irrigations with Tillering and early growth= 6 cm depth Grandgrowth= 10 cm depth Maturity= 5-6 cm depth Effective root zone= 90 cm Preseasonal sugarcane = 350 ha . cm and 32 to 35 irrigation
At initial stages weed control is more important In suru planting 2-3 times weeding In preseasonal planting 3-4 times weeding In Adsali planting= 4-5 times weeding Weedicides should be applied preemergence after planting but before emergence of weed or Metribuzine 1.0 – 1.5 kg /ha in 500-600 liter of water or 2,4-D (fernoxone) 1-1.5 kg /ha in 500 -600 liter of water or Glyphosate (Round up/Glycil) 0.6 – 1.6 kg /ha in 400-500 liter of water before planting sugarcane sets.
Red rot, smut, pineapple disease, Wilt, Ratoon stunting disease, Grassy shoot disease, leaf scald, Yellow leaf spot, Eye spot
Early shoot borer ,Top borer,Scale insect,White fly,White grub, White wooly aphid, Mealy bug. To control this pest Phorate 10 % 6-8 kg /acre or methly demeton 25 % EC or Diamethoate 30% EC or Endosulphan 35% EC 15 ml in 10 liter water 2-3 sprayings. For white fly Malathion 50 % EC 20 ml in 10 liter water.
Sign of maturity 1) leaves become yellow. 2) Plants stop growing and emergence of arrows in case of flowering varieties. 3) Swelling of eye buds. 4) Breaking of cane at nodes. 5) Increase sweetness of juice. 6) Cane gives metallic sound when tapped with fingernail at the internodes. 7) Brix reading should be 19-24 0c at the time of harvesting. 8) hand refractometer reading should be 21 to 24 0c.
Harvesting is done by cutting the plant at bottom with sharp chopper , detrash the trash and cut the top.
Average yield for
Suru planting= 100 tonnes /ha
Preseasonal planting= 125 tonnes /ha
Adsali= 150 tonnes /ha

1) Sugar industry is the largest agro based processing industry next only to textile in india having 450 sugar factories. 2) Sugarcane is a multiple product commodity crop. It produces about 10 tonnes sugar 4 tonnes Molassses, 3 tonnes filter cake, 9.3 tonnes furnace ash, 30 tonnes bagasse 150 KW electricity. 3) It serves as af ood , fuel fibre, fodder and foregin exchange earner. 4) It provides useful raw material to over 25 types of Industries which utilize its different components to produce sugar jaggery and khandsari. 5) it is also used in different agro industrial coproducts like alcohol fuel chemicals paper boards antibiotics, cattle feed and electricity. 6) sugarcane trash can be used as mulch and compost making
