RICE IN FIJI

• In Fiji, now rice is a common food for all ethnic
  groups and the per capita consumption rose from
  64 to 75 kg. Based on last 6 years of import data
  (2000- 2005), Fiji is importing about 33,720
  tons of rice for consuimption on average, costing
  F19.55m.
• Between 2005 and 2007, the government aimed to
  increase the rice production by 7,500 tonnes
  valued at F3million by spending F2.3 million
  through the Rice Revitalization Program.
• Paradoxically, the contribution of the
  agriculture sector to Fijis GDP has declined for
  the last several years, from 25 to 12 and the
  share of Rice to the GDP is very low. Also, the
  self-sufficiency ratio of rice declined from 65
  to 20. This situation shows that government
  should take immediate measures to strengthen the
  rice revitalization to make the country self-
  sufficient in rice.

• Actual yields are almost at par to achievable
  yields in high productivity in irrigated
  ecology
  
• Technology for breaking yield ceiling has to be
  generated
  
• Among the natural resources, water is becoming
  increasingly critical
  
• Water-saving technologies to be
  developed and tested on priority basis
  
• Cost of cultivation has become prohibitive
• Alternative cost-efficient
  technologies need to be tested
  
• Rainfed ecologies, particularly uplands and
  favourable shallow lowlands, are yet to witness a
  real yield breakthrough
  
• Varietal improvement needs greater
  thrust
  
• Hybrid rice technology a field reality but
• Hybrids with higher magnitude of
  heterosis for irrigated areas and hybrids under
  long-duration group for rainfed ecologies are
  need of the hour
• Genetic base of the HYVs/hybrids is quite narrow
• Proper assessment and corrective
  measures urgently needed

AICRIP TRIALS ON SRI AT GLANCE (2004 06)

AICRIP RESULTS (04-05) Multi-location trials co
nducted during 2004 and 2005 on System of Rice
Intensification (SRI) method, evaluated in
comparison with normal transplanting (NT) and
Integrated Crop Management (ICM) methods. Grain
yield recorded under SRI was significantly higher
under SRI compared to NT at 53 of the locations,
while it was similar to ICM at 33 of locations.
Higher grain yield under SRI was recorded in
diverse soil types, with wide range of soil pH
(6-8) under different regions which could be
associated with increased number of panicles per
unit area, biomass and panicle weight. However,
the cultivars used had significant inter-action
with method of cultivation at 28 of the
locations. Rice hybrids responded better than
varieties. Normal transplanting with wider
spacing nor SRI method with older seedlings did
not enhance grain yield significantly. It is also
observed that SRI could be adopted successfully
even under late transplanting conditions.
Conclusion SRI appears to be more promising in te
rms of grain yield although gains observed were
genotype- and location-specific. Further studies
are required to confirm these results.

• AICRIP RESULTS (05-06)
• Results of 27 multi location trials show
  significant variations among SRI, ICM CRC
  
• In Southern Zone, SRI ICM performed better
  (1-23) over CRC at CBC, ADT, RNR MND
  
• In Western Zone, SRI ICM recorded (4-7) higher
  yield over CRC.
  
• In Northern Zone, CRC was found better than SRI
  ICM methods.
  
• In Eastern Zone (PTNA, TBR, KNP, RAN), SRI ICM
  were superior to CRC.
  
• In Hill Zone, only at Khudwani, Umiam and
  Arudhatinagar SRI was found superior.

Conclusion It is confirmed that SRI methodolo
gy is location- and genotype-specific under same
date of sowing and planting.

Types of Rice Cultivation

• Japanese rice cultivation
• V-shaped rice cultivation
• Taiwan rice cultivation
• SRI cultivation
• Integrated Crop Management

Emphasis on water management
17
Work Plan/ Strategies

• Genetic enhancement of food crops
• Improvement for tolerance
• Improve levels of nutrition (Vitamin A, Zn and
  Fe)
  
• Fertilizer strategies for farmers organic
  farming
  
• Digital extension service to farmers (ADT)
• Studies on global warming and evaluation of crops
  under open air (elevated CO2 levels)
  
• Modern POPs and GAP for quality safety
• At all levels, invoke dormant propensity to serve
  farmers and poverty-stricken people with new
  technologies

18
Conclusions

• Agriculture technology and innovations by
  scientists outstripped the Malthusian population
  growth theory in India. Convincing finding --
  that holds good for Fiji too.
• Delineate or identify areas genotypes that are
  good for SRI in India.
  
• Encourage SRI in small holdings with priority for
  medium/long duration varieties/hybrids.
