  • Weak root system is due to less aeration. Delayed transplantation results in less panicle due to fall in temperature.

Transcript

  • 1. Experience on System of RootIntensification in the Sundarbans PRASARI
  • 2. RIVER-BANK FAILURE+SEA WATER SUNDARBANS WATERLOGCROP LOSS RAINFALL+ SALINITY GING DRY SOIL+SALINE SURFACE
  • 3. Factors contributing … HIGH WATER SCARCITYSINGLE RAINFALL +HIGH SALINITY INCROP-RICE+ IN JULY SUMMER (50% MORE)1 acre av. land (753mm) SUBMERGENCE LOSS OF ONLY NOMINAL 1.91t/ha GROP (as high SECOND CROP 70%) FOOD INSECURITY+60% DISTRESSED MIGRATION
  • 4. PROBLEM STATEMENT…• WATER LOGGING AND NO DRAINAGE• MONO-CROPPED (LOW YIELD-RICE)• HIGHER SALINITY AND LESS SWEET WATER IN SUMMER• SMALL LANDHOLDING• LACK OF FODDER & ORGANIC MANURE (LIVESTOCK DECREASING)• LACK OF FAITH ON NRM-AGRIL.• MIGRATION
  • 5. PRESENTATION SUMMARY….• SRI EVOLUTIONS0th YearYear-1Year-2Year-3• LEARNINGS• WAY-FORWARD…….
  • 6. SRI EVOLUTION (0TH YR)…• PARESH DAS• LAND-LESS• LEASED-IN 10 dcml. LAND• SUMMER-07-08• USED MOC+FYM CAKE• 240 KGS. OF RICE OVER TRADITIONAL 115 KGS.
  • 7. QUESTIONED ANSWERED(UN)(0TH? YR)…..SRI CAN BE DONE IN THE SUNDARBANS!CAN IT BE CALLED AS SRI?HIGHER WATER DEPTH AND STAGNATION VS. ALTERNATE DRY/WETYOUNG AND SINGLE SEEDLING CAN SURVIVE WATER PRESSURE?WHAT WOULD BE THE NUTRIENT DOSES?THE TRADITIONAL VARIETIES WOULD ALSO RESPONDUNDER SRI?IF YOU CAN’T SEE THE SOIL UNDER WATER-WHERE TO USEWEEDER?WOULD PEOPLE REALY BE READY TO PUT THEIR LAND ATSTAKE?
  • 8. SRI EVOLUTION (YEAR-1)…..• RECEIVED SUPPORT FROM SDTT• KHARIF-152 FARMERS IN 49 ACRE (+80 FARMERS IN SUMMER)• GREEN MANURE+DE-OIL CAKE BASED POP• 11 FARMERS TRIED LOCAL VARIETIES• 15 FARMERS LOST CROP IN SUMMER
  • 9. QUESTIONED ANSWERED(UN)(1ST? YR)…..SRI IS ONLY FEASIBLE FOR THE UPLANDS?WHAT TO DO WHERE WATER STAGNATION IS VERY HIGH?WEEDER OPERATION CONTRIBUTES POSITIVELY TO THE YIELD EVEN IFYOU CAN’T SEE THE SOIL!ARE THE FARMERS TAKING UP SRI AS THEY ARE PROVIDED WITH THEINPUTS COST? SOURCE OF ORGANICS?LOCAL VARIETIES ARE DOING BETTER THAN THAT OF TRADITIONALPRACTICES-AROMATIC/MORISHSHAL VARIETY WOULD ASSURE MORERETURN UNDER SRI?DE-OIL CAKES REMAINED ‘CAKES’ EVEN AFTER THE SUMMERHARVEST!ALTERNATE DRYING IN SUMMER RISES SALINITY AND CROP LOSSES INSUMMER!
  • 10. SRI EVOLUTION (YEAR-2)…. • SRI WITH 1010 FARMERS ON OVER 470 ACRES (EVEN-AYLA) • REGISTRATION FEES VS. 8% DROP OUT • ALLOWED ORG+CHEMICAL IN SUMMER • USE OF EM-TECHNOLOGY • LOW LAND SRI ENHANCED 50% YIELD:EARLY TRANSPLANTATION • 30 TO 40% CROP LOSS IN SUMMER • 118 FARMERS PRACTICED LOCAL VARIETIES (28% in low land,22% aromatic)
  • 11. QUESTIONS ANSWERED(UN)(2ND? YR)…..WOULD THE DROP OUT RATE INCREASES IF THE INPUTS SUPPORT ISMINIMUM?WOULD THE FARMERS GO BACK TO PREVIOUS CHEMICAL N-P-K ONLYAS THERE IS NO FYM/ORG. SUPPORT?HOW TO PLAN FOR HIGH WATER ZONES IN ADVANCE?HOW LONG TO EXPERIMENT WITH THE SUMMER RICE LOSSES?IS THERE ANY ALTERNATIVE CROP FOR THE SALINE DELTA INSUMMER?IS THIS ENOUGH TO ‘SEE’ THE FAMILIES ONLY IN THE KHARIF ANDFORGETING FOR 6 MONTHS?HOW TO RESTRICT MIGRATION AND GETTING PEOPLE’SNRM FAITH BACK WHEN HIGH SALINITY & NO SWEETWATER?
  • 12. SRI EVOLUTION (YEAR-3)…..• MAPPING THE WATER LEVELS FOR ALL VILLAGES• SRI WITH 1430 FARMERS• 221 FARMERS WITH LOCAL VARIETY (54% IN THE LOW LAND, 17% AROMATIC)• SRI IN MUSTARD WITH THREE VARIETIES (B9,RP-09,RAIJATA) AS SUMMER ALTERNATIVE• NOMINAL DROP OUT DUE TO MIGRATION THOUGH MAJOR INPUTS CONTRIBUTION FROM FARMERS• SRI POCKETS HAVE BEEN DEVELOVED• THREE LOCAL SHOPS WITH CLEANED GODOWN OF DE-OIL CAKES AT THE END OF KHARIF…
  • 13. QUESTIONS ANSWERED(UN)(3RD? YR)….. WOULD VILLAGERS TAKE UP THE MUSTARD CROP TOREPLACE SUMMER RICE?CAN SRI BE ALIGNED AS THE YEAR THE ROUND ACTIVITY?LET’S EXPLORE HOW THE OVERALL SUPPORT COSTVARRIES OVER TIME!WHAT IS THE “SRI INTERNALIZATION”LEVEL OF THE COMMUNITY?

  • 16. SRI INTERNALIZATION-A CASE STUDY • Transplanting:5/7/11 • Un-interrupted rain: 03/08/11 to 20/8/11 • Complete submergence:9/8/11 • Drained out:27/8/11 • Lost: 90% of hills • Fertilization to survived hills: 29/08/11 • Re-transplanting the panicles: 04/09/11 • Weeding: 11/09 and 18/09/11 • Date of harvest: 13/12/12 • Average Ht.: 122.2 cm • Panicle length: 27.5 cm • Effective tillers: 16 • Grain/panicle(av.):271 • Chaffy/panicle:23 • 1000 grain wt.:25 gm • 25 sq. mtr grain:13.5 kg. OVER 700 FARMERS FOLLOWED THIS METHOD AND HARVESTED GOOD RETURN IN THE DELTA in-spite of submergence loss
  • 17. UNADDRESSED ISSUE OF SALINITY,SWEET WATER AND MIGRATION….. PROBLEMS • SUMMER SALINITY • NO DRAINAGE • NON AVAILABLE SWEET WATER IN SUMMER • LESS RETURN FROM NRM LEADING TO MIGRATION SOLUTION • FAO OF UN RECOMENDSSUNDARBANS WATER HARVESTING STRUCTURES (EX-SITU) AS A SOLUTION
