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

Public ISBD in Rice research in Nepal : Proceedings of 24th National Summer Crops Research Workshop, Khumaltar, Lalitpur, 30-31 June 2004 / Adhikari, N.P.     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 in Rice research in Nepal : Proceedings of 24th National Summer Crops Research Workshop, Khumaltar, Lalitpur, 30-31 June 2004 / Adhikari, N.P.     On-farm and on-station evaluation of system of rice intesification (SRI) for increased production of rice [printed text] / J.
