Title : Effect of enriched C02 on rice under open top chamber condition at Khumaltar Material Type: printed text Authors: Sherchan, K., Author ; Shrestha, S., Author ; Alok Sharma, Author Pagination: 60-66 p. Languages : English (eng) Keywords: Enriched C02, open top chamber, rice yield Abstract: During panicle initiation and flowering singes, C02 enriched plot had the highest leaf area index (LAI) in the first year. Minimum temperature was slightly higher in C02 enriched plot C02 enriched plot had 15% and ambient plot had only 10% increase in grain yield as compare to the field. The C02 enriched plot had almost higher straw yield than others. It was about 30 to 37% higher than field plot. Number of tillers per square meter was highest in C02enriched plot followed by ambient and field plot. Plant height and panicle length were both higher in C02 enriched plot. C02 enriched plot had lesser N, P and K content in grain, straw and root. However, organic carbon (OC) content in root was more than 100% as compare to the field plot. C:N ratio were also higher except in the grain. Higher grain yield in C02 enriched plot was due to higher number of tillers per square meter, seeds per panicle and panicle length.

in Proceedings of the 27th National Summer Crops Workshop, held at Rampur, Chitawan, 18-20 April 2013, Vol. I / Giri, Y.P.
Title : Study on rice and CO2-C emission under differnt temperature regime in mid-hill conditon Material Type: printed text Authors: Ghanashyam Malla ; Gautam, Anand Kumar, Author ; Amit Timilsina, Author Pagination: 247-249 p. Languages : English (eng) Keywords: CO2-C emission ; open top chamber (OTC) planting dates rainfall pattern Abstract: Elevated temperature and unusual rain is adversely affecting agricultural crops. Threats in the
rice crop due to temperature rise are: change in crop phenology, physiology, grain yield and
even crop success along with moisture and nutrient availability. An experiment was carried
out in field and open top chamber (OTC) to study the response of rice variety (Khumal 4),
C02-C emission under different temperature regime and different dates of transplanting (19th
June, 29th June, 9th July) in 20 I 0 and 2012. Experiment showed that heading and maturity
were 4-7 and I 0-12 days earlier in OTC .Average grain yield was higher by 9.2% in OTC.
Higher average grain yield was recorded in 3'd date of planting under both conditions.
Average daily temperature was 4-5°C higher in OTC. C02-C emission under OTC was nearly
24% higher compared to field, whereas organic carbon in OTC was lower compared to field.
Thus, yield can be increased under elevated temperature and unusual rainfall with proper
water management practices. Therefore, a strong monitoring system on climatic parameters
and their impact on crop have to be regulated to increase rice crop production.Link for e-copy: http://elibrary.narc.gov.np/?r=904 Study on rice and CO2-C emission under differnt temperature regime in mid-hill conditon [printed text] / Ghanashyam Malla ; Gautam, Anand Kumar, Author ; Amit Timilsina, Author . - [s.d.] . - 247-249 p.
