Title : Appropriate plant spacing for cauliflower intercropping under maize Material Type: printed text Authors: Khatiwada, P.P., Author Pagination: 36-40 p. Languages : English (eng) Keywords: Cauliflower, intercropping, maize, plant spacing Abstract: This investigation was carried out to identify appropriate combination or plant population of maize and cauliflower for intercropping in potato + maize cropping system. The experiment was carried out at Sinduwa Sub-station, Dhankuta during 1998 to 2000. Three spacings for both of the crops were tested and cauliflower was transplanted after the harvest of potato. Maize grain yield was significantly (P < 0.001) higher (2.66 t/ha) in closer (100- x 25-cm) spacing. Similarly, closer spacing (45- x 30-cm) of cauliflower also yielded significantly (P < 0.01) higher (5.08 t/ha) curd yield than that of 60 x 45-cm (3.87 t/ha). A bivariate analysis of both crops showed that increasing plants population either of cauliflower or maize gave the higher yield. Falling apart of the non-confidence region of 26,666 maize with 74,074 cauliflower plants/ha with 40,000 maize with 74074 cauliflower plants/ha (higher maize yield) and 20,000 maize with 74,074 cauliflower plants/hn (higher cauliflower yield) demonstrate that 26,666 maize population with 74,074 cauliflower population/ha was the more appropriate mix to get balance yield of cauliflower and maize.

Title : Effect of Planting Dates and Plant Spacing On.Late Season (March-May) Cauliflower Production Material Type: printed text Authors: P. P. Khatiwada, Author ; Chaudhary, B.P., Author Pagination: 328-333 p. Languages : English (eng) Keywords: cauliflower, date of transplanting, spacing Abstract: Afield experimellt was carried out for three consecutive years ( 1997-1999) in upper mid hills
( 1940 mas/) to identify an appropriate spacing and date of transplanting for the late season
(March -May) caulijlov..'.!r production using a11 open pollinated variety. Four different plant
spacing (45x30 em, 45x40 em, 45x50 em and 45x60 em) and the same mtmber of
transplallting dates ( 1" week of February, 3rr1 week of February, 1" week of March and 3"1
week of March) were tested in factorial arrangements in randomized complete block design
with three replications. Among the tested plant spacing, 45x30 em between row and plants
respectively yielded the highest ( 19.63 t/ha) curd yield, which was followed by 45x40 em
spacing ( 18.5 tlha). None significant yield difference of curd yield between 111 week of
February ( 18.55 tlha) and 11
' week of March ( 18.98 t/ha) transplanting clearly demonstrates
that Kibo Giant variety of cauliflower ca11 be transplanted up to the first week of March for
late season production without loosing its genetic potelllial. Higher yield than that of
national average from the last date of transplallling i.e. 3'd week March ( 13.9 t/ha) clearly
point out a need for further testing of the dates by using the same variety. Recommendation
of closer spacing simultaneously demands a new rate of fertilizer requirement. Hence, an
investigation for appropriate dose of chemical fenilizers using the new spacing is pivotal for
the technology promotion.Link for e-copy: http://elibrary.narc.gov.np/?r=553 Effect of Planting Dates and Plant Spacing On.Late Season (March-May) Cauliflower Production [printed text] / P. P. Khatiwada, Author ; Chaudhary, B.P., Author . - [s.d.] . - 328-333 p.

Title : Response of hybrid rice to different spacing and nitrogen levels under irrigated transplanted condition Material Type: printed text Authors: Pradeep Shah ; Mitali Sah, Author ; Anisur Rahman Ansari, Author Pagination: 241-246 p. Languages : English (eng) Keywords: Hybrid rice ; spacing nitrogen level grain yield irrigated Abstract: A field experiment was conducted at the Regional Agricultural Research Station, Parwanipur,
Bara, Nepal during summer seasons of 2011 and 2012 to assess the performance of hybrid
rice under varying levels of spacing and nitrogen under irrigated transplanted condition. Nine
treatment combinations of three spacings viz. 20 x 15, 20 x 20 and 20 x 25 em and three
nitrogen levels i.e. 80, 120 and 160 kg N ha· 1 were laid out in factorial Randomized Complete
Block Design, replicated thrice. The two years result revealed that spacing of 20 x 20 em and
application of 160 kg ha·1 nitrogen recorded significantly higher grain and straw yield. The
yield attributes viz. panicle length, spikelets panicle- 1
, 1000-grain weight, weight of grains
panicle-1 and filled grains panicle·' varied significantly ampng the treatments. Likewise,
application of 160 kg N ha·' recorded significantly higher plant height, dry matter and tiller
planf1
• Spacing of20 x 25 em recorded higher plant height which was at par with 20 x 20 em.
Biomass and tiller planf1 were significantly higher with spacing of20 x 25 em. Highest mean
grain yield of 5.10 t ha· 1 was found in spacing of20 x 20 em and 5.33 t ha·1 in 160 kg N ha·'

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.
