1 Growth and Yield Components between Normal Fertilizer and Slow Release Fertilizer Application in Parachute Transplanting Godfried Savi Papua New Guinea And H.M.J.K.Herath Sri Lanka

2 INTRODUCTION  HIGH PRODUCTION COST AND LOW RETURN IS A HAS CREATE A LOW FARMING INTEREST.  A SIMPLER CULTIVATION PRACTICES IS REQUIRED.  AS ORDINARY CULTIVATION PRACTICES IS LABOUR INTENSIVE FOR MANY PART-TIME AND AGEING FARMERS.  COMBINATION OF PARACHUTE TRANSPLANTING METHOD (OLD) AND SLOW RELEASE FERTILIZER APPLICATION (NEW) IS REQUIRED.

3  SRF IS CONVENIENT - EASY OPERATION, - STABLE YIELD, - LOW LABOUR INPUT AND - ENVIRONMENT CONSERVATION

4 MATERIAL  VARIETY : HITOMEBORE (A LATE EARLY MATURING VARIETY)  CULTIVATION DATE : 4 TH APRIL TO 13 TH SEPTEMBER 2001  FIELD SIZE : - NORMAL FERTILIZER- 500M 2 - SLOW RELEASE FERTILIZER - 237 M 2

5  FERTILIZER:  BASAL FOR NF - AMMONIUM SULPHATE (N) 40 KG/HA - POTASSIUM SULPHATE (K) 80 KG/HA SRF- AMMONIUM SULPHATE (M) 0 KG/HA - POTASSIU M SULPHATE (K) 80KG/HA  TOP DRESSING FOR NF - AMMONIUM SULPHATE (N) 10 KG/HA - POTASSIUM SULPHATE (K) 50 KG/HA  FOR SEED BOX: SRF NK 301-100 /HA

6  NURSERY SEED BOX - 61CM X 31CM X 2.7CM - TOTAL CELLS 578 - 7 BOXES SEEDLINGS (SRF) - 15 BOXES SEEDLINGS (NF)  TREATMENT - SRF CAPSULES IN NURSERY BOXES - NF WITH TOP DRESSING

7  LAND TILLAGE: - PRIMARY TILLAGE WAS DONE ON 19TH APRIL. - PUDDLING AND LEVELLING WAS DONE WITH LEVEE MAKING ON 27 TH OF APRIL AND 10 TH OF MAY.  SEED SELECTION: - BY 1.13 SPECIFIC GRAVITY OF SALT WATER SOLUTION AT 200G SALT : 1 LITER WATER METHOD

8  DISINFECTION: BENLATE-T (THIRAM20%,BENOMLY20%) FOR SEED BORNE DISEASE 2 ND OF APRIL.  SOAKING: TO ACCELERATE SPROUTING OF SEEDS FOR UNIFORM GERMINATION AND DRY. FROM 6 TH OF APRIL - 8 TH OF APRIL.  SEEDING: 3 SEEDS PER CELL PER NURSERY BOX (52 G) ON 10 TH OF APRIL.

9  INCUBATION : - ALL NURSERY SEEDED BOXES PLACED INTO INCUBATOR AT TEMPERATURE 32 0 C TO ACCELERATE GERMINATION.  NURSERY CARE : -ALL SEEDLING COVERED BY VINYL SHEET TO PROTECT AGAINST COLD DAMAGE. -IRRIGATE WATER AS REQUIRED.  TRANSPLANTING : -SEEDLING TRANSFERRED TO PADDY FIELD FOR ADOPTAION (2 ND – 10 TH OF MAY) - MANUAL TRANSPLANTING BY PARACHUTE METHOD TO SRF AND NF FIELDS.

10  FERTILIZER: NURSERY: - ADD SRF CAPSULE(NK 301-100) TO NURSERY BOX (545G) PER BOX. - ADD MANUFACTURED SOIL INTO NURSERY BOXES AND WATER. BASAL (NF) : AMMONIUM SULPHATE 40KG/HA POTASSIUM SULPHATE 80KG/HA TOP DRESSING (NF) : ( 14 DAYS BEFORE HEADING ) AMMONIUM SULPHATE 10KG/HA POTASSIUM SULPHATE 50KG/HA WEEDING – 1 ST SPARKY STAR - 10KG/HA 2 ND SIMTRYN (1.5%) - 30KG/HA

11 PEST / DISEASE: MONCUT (FLUTOANIL)- 30KG/HA IRRIGATION DRAINAGE: -10 CM WATER DEPTH FOR FIRST 10 DAYS TO PREVENT FROM COLD DAMAGE. -MAINTAIN 3 CM WATER LEVEL TILL MID SEASON DRAINAGE. -COMPLETE DRAINAGE 7 DAYS BEFORE HARVESTING  HARVESTING: MANUAL HARVESTING OF BOTH FIELD, DRY 15 DAYS UNDER SHED  THRESHING: AFTER 15 DAYS DRYING AT 16% MOISTURE CONTENT

20 CONCLUSION  PARACHUTE TRANSPLANTING DOES INCREASE YIELD AND REDUCE COST AND TIME IN RICE CULTIVATION TRANSPLANTING WITH THE INCLUSION OF SRF AND THE PARACHUTE TRANSPLANTING METHOD IS MORE CONVENIENT AND LOW MANPOWER HOURS FOR PART-TIME FARMERS TO PURSUE THIS PRACTICE TO OBTAIN MAXIMUM YIELD AGAINST OTHER PRACTICES AS MACHINE, HAND TRANSPLANTING AND DIRECT SEEDING.
