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.

Title : Performance of open pollinated full season maize varieties in the central hills of Nepal Material Type: printed text Authors: Pokharel, B.B., Editor ; Koirala, K.B. ; K Baral, Author ; S Subedi, Author ; A Timilsina, Author ; S Thapa, Author Pagination: 59-65 p. Languages : English (eng) Keywords: Open pollinated ; full season central hills of Nepal Abstract: Maize is the staple crop of mid and high hills of Nepal. Farmers are in continuous search
for stable and high yielding genotypes that can perform well under ra.infed condition. In
order to identify suitable maize genotype addressing the fanners demand, series of field
researches like intermediate yield trial (TYT), coordinated varietal trial (CVT) and
coordinated farmers field frial (CFFT) were conducted at the research field of HCRP and
the farmers' field of Dolakha and Ramechhap during the rainy season of 20 11 and 2012.
The testing materials were made available from NMRP, Rampur. The design was laid out in
RCBD with three replications. Twelve genotypes in IYT and CVT each and 6 genotypes in
CFFT were tested. The result from IYT, CVT and FFT showed significant variation among
genotypes for grain yield and associated traits. In IYT genotypes 07SADVI, TLBRS07F14
and ZM-401 were found superior. In CVT, genotypes Rampur S03F04 and Rampur S03F08
were found promising. Genotypes P501SRCOIP502SRCO, Across9942/Across9944, and
BGBYPOP were found· superior in the farmers' field experiment and could be
recommended for mid hill regions of Dolakha and similar environments. Similarly, hybrids
RML-4/RML-17 and RML-32/RML-17 were found encouraging.Link for e-copy: http://elibrary.narc.gov.np/?r=930 Performance of open pollinated full season maize varieties in the central hills of Nepal [printed text] / Pokharel, B.B., Editor ; Koirala, K.B. ; K Baral, Author ; S Subedi, Author ; A Timilsina, Author ; S Thapa, Author . - [s.d.] . - 59-65 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.
