Title : Carbon dioxide emission from soil grown to wheat crop at Khumaltar, Lalitpur Material Type: printed text Authors: S Kandel, Author ; S.C Shah, Author ; Gautam, A.K., Author ; K.R Pande, Author Pagination: 412-420 p. Languages : English (eng) Keywords: Carbon dynamics,CO2 emission, mulching, zero tillage. Abstract: Changes in farming practices could be an effective way to reduce carbon (CO2-C) emissions from agricultural lands thereby sequestering more carbon in the soil. A field experiment was conducted on an acidic silt loam upland soil of Khumaltar, Nepal during the dry season of 2011/2012. The study evaluated soil CO2 - C emission from a wheat field as influenced by tillage, mulch, and nitrogen (N) application. The factorial experiment laid-out on a split-split plot design consisted of three replications of 12 treatment combinations, i.e., two types of tillage (zero and conventional) on a main-plot, two levels of mulch (zero and 4 t ha-1 of rice straw) on a sub-plot and three levels of N application (zero, 100 and 150 kg ha-1) on a sub-sub plot. The crop growing season in this region is relatively longer primarily due to the effects of low temperature and high elevation (1300 masl); therefore, wheat (var. WK-1204) planted on December 6 of 2011 matured in six months (harvest date June 2 of 2012)………………..

Title : Efficacy of nitrification inhibitor in co2-c emission from wheat field at Khumaltar Material Type: printed text Authors: G Malla, Author ; A. Sharma, Author ; H Devkota, Author Pagination: 390-395 p. Languages : English (eng) Keywords: Wheat, Climate Change, Carbon Em ission, and Closed Chamber Abstract: Application of appropriate dose of nitrification inhibitor and nitrogenous fertilizers is the prime concern of climate change and rainfed wheat (Triticum aestivum L.). In this study, two nitrification inhibitors : ammonium sulphate and neem oil were tested to study the effect of nitrification inhibitor and the performance of wheat yield at Khumaltar during the year 2009 to 2010. The experiment was conducted in closed chambers in RCBD design with 7 treatments and 4 replications. Wheat yield ranged from 1 .25 to 2.89 ton/ha and the carbon emissions from 44.59 to 125.35 mg/m2/hr was found in the study......................

Title : Potential options for sustainable land management and intensified agriculture Material Type: printed text Authors: R.M Bajracharya, Author ; K. Atreya, Author ; N Raut, Author ; BM Dahal, Author ; H.L Shrestha, Author ; N.R Dahal, Author ; D.K Gautam, Author ; P Karmacharya, Author Pagination: 111-127 p. Languages : English (eng) Keywords: Agro-forestry, biochar, carbon sequestration, crop diversification, soil quality. Abstract: The soil and land resources play a vital role in the local livelihoods of rural communities as well as in the national economy. With much of the arable land already under cultivation and the ever-increasing demands for food and fiber, agriculture has already moved towards intensification. Yet, producing greater numbers of crops and quantities of food, fibre and other materials on the same parcel of land often leads to soil fertility and productivity decline with overall degradation of soil quality. Therefore, ways and means to intensify agriculture to eN hance productivity without degrading the soil and land resource base have become imperative. To this end, agro-forestry, agro-slivi-pastoral systems, and the adoption of a variety of crop, soil and water management and conservation practices offer potential to deliver multiple benefits without sacrificing the very resource upon which the human population depends………………………..
