On-farm and on-station evaluation of system of rice intesification (SRI) for increased production of rice / J. Tripathi

Title : On-farm and on-station evaluation of system of rice intesification (SRI) for increased production of rice Material Type: printed text Authors: J. Tripathi ; Bhatta, M.R., Author ; S Justise, Author ; R.B Neupane, Author ; N.K Shakya, Author ; B.R Ghimire, Author ; T.B Chhetri, Author Pagination: 243-252 p. Languages : English (eng) Keywords: Rice ; Date of seeding seedling age retransplanting herbicides spacing and N levels 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. ·Link for e-copy: http://elibrary.narc.gov.np/?r=1109 On-farm and on-station evaluation of system of rice intesification (SRI) for increased production of rice [printed text] / J.

kglha (1996) and 2290 and 2359 kglha (1997) transplanted on Bhadra 15'h {Sept. 3nJ and Aug.
3 r') respectively under rainfed lowland condition. Seeding age upto 60 days for Chaite {spring)
season and 50 days for Bhadaiya season could be used for Chaite-2, Chaite-4, Chaite-6 and
Radha-32, Radha-12. Radha-11 and Radha-7 did not differ due to age of seedling i.e. 20-60 days
at Tarahara. Similarly difference upto 65 days did not hove significant on yield of genotypes
Radha-11, RP /070 and RD-21 at Parwanipur. Ear(v and medium maturity varieties produced
maximum yield March 15'h to April 15'1

grain yield of May 15'h and 30'1
' seeding respective(v. Radha-7 and Makwanpur-1 could be retransplanted
instead of old seedlings. In varieties Masu/i, Radha-9 and Local Basmati, use of
older seedling can substitute re-transplanting. Spacing of 20cm x 1 5cm. and 20cm. x 20cm. was
suitable for ear(v and medium/late maturing rice varieties respectively. Rice transplanted either
one or more than two seedlings had no effect on grain yields. For optimum yield balance dose of
