  • COASTAL LANDS Young deposition of alluvial soils 30% of the cultivable area (around 1million ha) Coastal area includes 13 districts 49% of the coastal area is constituted by theGanges tidal flood plain

  •  Tidal flooding Salinization Threat of cyclones Storm surgesMain features of coastal area
  • Coastal agriculture Low yield Local varieties Low cropping intensity Dominant cropping pattern- Fallow- T. Aman-Fallow Minimum use of technologies
  • Saline soilSaline soils have a saturated extract conductivity (ECse) of>4dS/m, pH<8.5, have <15% exchangeable Na% (ESP).Major ions Na+, Ca2+, Mg2+, Cl-, SO42-Cause : Primarily by toxicity from Na+ and Cl-.Mechanism of plant death: The high osmotic pressure in the soilsolution causes a correspondingly low soil water potential,and when in contact with a plant cell, the solute moves towardthe soil solution and the cell collapses (called plasmolysis)Salinity Starts from November Peak March/April (5-15 dS/m) Minimum July/August (2-4 dS/m)
  • Coastal Agriculture Management Strategy1. Management of Soil salinity2. Selection of suitable crops
  • 1. Management of Soil Salinity Protective embankment Provision of sluice gate on the embankmet Leveling of land Storing of excess water for irrigation Frequent irrigation Well drainage system Organic mulches
  • Contd. Ridge-furrow system of cultivation Application of Gypsum (CaSO4.2H2O),Ca2+ reacts withNa+, Na+ moves below root zone Keeping the lands covered in summer and winter Fertilization of crops Cultivation of saline tolerant crops/varieties

Selection of crops
  • A. Physical constraints Saline soil Lack of fresh water Late draining condition High saline ground water table Low organic matter Late transplantation and harvesting ofaman rice Poor polder management/defective sluicegateConstraints of coastal agriculture
  • Shorter winter periodHeavy consistencyPoor number of salt tolerant cropsLack of suitable technology for salinitymanagementDifficult communicationPoor marketing facilities
  • B. Biological constraints Severe disease and insect infestation Global warming because of recent climate changemakes the situation more susceptible.
  • C. Social constraints Development of injudicious gher for shrimpculture Providing saline water in the gher Injudicious activities resulting perennial waterlogging pockets
  • Saline tolerant crop

  • CULTIVATION OF MUSTARD AS RELAY CROP WITH T. AMAN INT. AMAN- FALLOW- BORO CROPPING PATTERNDescription  Mustard is broadcasted in standing T. Aman field before 15days of harvest. Mustard seeds germinate with residual soil moisture After harvest of T. Aman rice, mustard plant attains aconsiderable height and its canopy acts as mulch. Soil moisture evaporation is restricted due to canopy shadeand soil salinity cannot reach at harmful level.
  • DESCRIPTION  Mustard can grow without interruption of soil salinity. All the recommended fertilizers except urea are appliedbefore 2/3 days of broadcasting.Urea is top dressed at 20 DAS One irrigation is applied during flowering stageVARIETY Short duration mustard variety (Tori-7, BARI sarisha 9)for T.

  • CULTIVATION OF POTATO IN RAISED BED WITH MULCHDescription  Three to four ploughings and then making 15 cm raised bed All the recommended fertilizers except urea are applied atfinal land preparation Urea is applied as top dress at 30-35 DAS and the irrigationand earthling up are done followed by mulch Mulch inhibits soil salinity by suppressing capillarymovement Whole potato tuber is sown as seed keeping 60 25 cmspacing Straw mulch is applied after top dressing irrigation andearthing upVariety Daimant, Asterix and CourageYield 20-35 t/ha
  • CULTIVATION OF WHEAT WITH ZERO TILLAGEDescription  Dominant cropping pattern : Fallow- Fallow- T. AmanShort duration T. Aman variety (BRRI dhan 33 and BRRIdhan 39) is cultivatedAfter harvesting of T. Aman rice, wheat seeds are broadcasted /placed in furrowSeeds germinate with inherent soil moistureAll the recommended fertilizers except urea are applied before2/3 days of sowing and urea is applied at 45 and 65 DAS Two irrigations are applied at CRI and PI stage the crop field is irrigated with surface water of pondVariety Sourov, Gourov, Prodip , Protiva, etcYield 2.5-3.0 t/ha

  • YEAR ROUND VEGETABLES PRODUCTION ON GHERBOUNDARYDescription Vegetables cultivation is limited due to lack ofavailability of land in southern gher areasIn this situation , both broad gher boundary(>1 m)and narrow gher boundary (<1m ) are selected forvegetables cultivationAll the recommended fertilizers for respectivecrops are applied before final land preparation

  • PRODUCTION OF WATER MELON IRRIGATING BY SURFACEWATER FROM ‘KUNI’Description  Water melon is cultivated after harvest of T. Aman riceagainst Fallow- Fallow- T. Aman cropping pattern After harvest of T. Aman rice, the land is not in joe condition When land is in joe condition, the soil salinity remains high As a source of irrigation , canal water is also in saline But comparatively, the water salinity of ‘Kuni’ is low. So, thefresh surface water of kuni can easily be used to irrigate thewater melon field ‘Kuni’ is a special type of mini pond made in the middle ofthe crop field which size is 25 15 6‘.Variety World queen, Hunter and Field masterYield 50-60 t/ha
