Title : Effect of Seed Priming on Germination, Field Emergence and Yield in Carrot (Daucus carota L.) Material Type: printed text Authors: K. K. Paudel, Author ; Shakya, S.M., Author ; M.D Sharma, Author ; K.R Dahal, Author Publication Date: 2015 Article on page: 16-26 p. Languages : English (eng) Keywords: Carrot, priming, germination, emergence, vigor Abstract: A field experiment was carried out at Rampur, Chitwan in split-plot design to study
the effect of priming of carrot seed on germination, early emergence, field
emergence, plant stand establishment and root yield and quality. The treatments
consisted of two commercial varieties of carrot (New Kuroda and Nantes Fancy)
as main plot and seven levels of seed priming as sub-plots with 3 replications. The
treatment imposed seeds for the field experiment were also used for laboratory
test with four replications. New Kuroda exhibited higher vigor index (637.2),
faster early emergence (8.33 days), highest field emergence (56.33%) and plant
stand (66.67%), thickest cortex diameter (1.70 cm) and higher economic yield of
22.13 t ha-1 (50.65% more than control) in 24 hrs. seed soaking in tap water than
in non-primed seeds where as Nantes Fancy showed faster early emergence (8.66
days), highest field emergence (55.33%), higher plant stand (69.33%) and higher
yield of 17.69 t ha-1 (9.94% more than control) in 12 hrs. seed soaking in 400 C
warm water.

Title : Graham’s Colorimetry as an estimate of Soil Organic Carbon in Chitwan Valley Soils, Nepal Material Type: printed text Authors: R Ghimire, Author ; S.C Shah, Author ; K.R Dahal, Author ; J.G Lauren, Author ; Adhikari, C., Author Pagination: 405-409 p. Languages : English (eng) Keywords: Colorimetric method, dry combustion, soil organic matters, texture Abstract: Soil organic carbon (SOC) influences soil physical and chemical processes, and serves as repository source of plant nutrients. Limited information is available concerning SOC status of different layers in Nepalese soils. Two hundred soil samples from five different soil depths (0-5, 5-10, 10-15, 15-30 and 30-50 cm) of Rampur and Baireni, were analyzed to evaluate the precision of Graham’s colorimetric method of SOC analysis. The SOC values obtained from Graham’s colorimetric method were compared with dry combustion SOC values for the same soil samples………………

Title : Technologies for Organic Crop Nutrient Management System (OCNMS) in Nepal: Practices and promises Material Type: printed text Authors: K.R Dahal, Author Pagination: 383-391 p. Languages : English (eng) Abstract: Nepal, an agrarian country practicing self-sustained agriculture for generations, was used to be completely organic until late 1950s, and was self sufficient in food. The growing population, then after, necessitated a faster increase in food production, which, and also inspired by the success of “green revolution agriculture” in neighbouring countries, instigated Nepal to introduce high yielding varieties of food crops and agro-chemicals as demanded by them. The mission was successful in increasing food production to some extent. However, the recent decline in the yield of most of the crops, progressive degradation of soil and environment, food poisoning, increased cost of cultivation, etc. have seriously questioned the sustainability of chemical intensive agricultural systems in Nepal. Now about 60% of our agricultural soil has fallen under low category of organic matter content and 67% of the country’s soil is acidic in reaction. Unbalanced and unscientific use of urea has created unfavorable conditions for soil health as a result of which the soils have become weak and fertility has been declining at an alarming rate…………………
