| Abstract: |
System of Rice Intensification (SRI) is a technique of agronomic manipulation to improve
physiological activities of rice plant for increased rice yield SRI involves transplanting of young
and single seedling in comparatively wider spacing with provided irrigation, weed and nutrient
management practices. The results of different SRI experiments conducted in 2001102, 2002103
and in 2003/04 indicated tremendous scope to increase rice yield if SRI practices adopted
properly. Three years results suggested that comparatively longer duration varieties with closer
spacing (20X20 to 30X30cm) did better under SRI techniques when provided weeds were
controlled effectively. Three rotary weeding followed by hand weeding found effective to control
weeds. Experimental results suggested that ten days old seedlings can be transplanted either
single or double seedlings/hill. No significant differences in time gap between uprooting to
transplanting suggested that transplanting within 15 minutes from uprooting is not so necessary if
seedlings could be protected (both root & shoot) form drying effects. Weeds were noticed as
major problem in SRI particularly with wider spacing as compared to farmers practice. However,
water management is another issue need to be shorted out as frequent drying and wetting had
little deleterious effect on grain yield and also increased the cost of irrigation. · |
