Languages : English (eng) Keywords: Extractable magnesium, global positioning system (GPS), soil fertility maps soilfertility status. Abstract: A study to examine soil fertility status and preparation of their maps of the National Wheat Research Program, Bhairahawa was conducted. The research farm is situated within latitude 27º31’49”N and longitude 83º27’36”E at altitude 82 masl. Fifty eight samples were collected randomly at depth 0-20 cm. The specific locations of various soil sampling points were identified using Global Positioning System (GPS). Soil samples thus collected were analyzed for their texture, pH, OM, N, P, K, Ca, Mg, S, Zn, Fe, Cu, and Mn status following standard methods in the laboratory of SSD, Khumaltar………………

Title : Biochar: Its role in soil management and potentiality in Nepalese Agriculture Material Type: printed text Authors: S.P Vista, Author ; A.G Ghimire, Author ; S.H Peter, Author ; S Shackley, Author ; B. H. Adhikary, Author Pagination: 174-177 p. Languages : English (eng) Keywords: Biochar, degraded and spoiled lands, Nepalese agriculture tremendous soilpotentiality management. Abstract: Biochar, the final product of pyrolysis of biomass, can be used as a soil amendment to increase plant growth, yield, improve water quality, increase soil moisture retention and availability to plants, reduce soil emissions of greenhouse gases (GHGs), reduce leaching of nutrients, reduce soil acidity, and reduce irrigation and fertilizer requirements. These properties of soil are very dependent on the properties of the biochar, and may depend on site specific ecological conditions including soil type, condition (depleted or healthy), temperature, and humidity. Biochar can be used in the reclamation of degraded and spoiled lands (acidic, alkaline, sodic and saline soils)…………………………..

Title : Can organic farming sustain crop productivity in Nepal: A Review Material Type: printed text Authors: Adhikari, N.P., Author ; S.P Vista, Author Pagination: 418-425 p. Languages : English (eng) Abstract: Balanced and adequate application of all nutrients is a key factor for enhancing crop productivity in a sustained basis. Organic farming has been gaining popularity in today's agriculture. Hence imitators and followers of organic farming are increasing day by day. In the present Nepali context, there has been a debate with the emergence of the concept of organic farming/sustainable agriculture. Research papers on sustainable nutrient management for increasing productivity were reviewed and debatable issues were analyzed. However, conclusions drawn from many countries with hundred years of experiments have shown that the use of organic manure yielded quality products but inorganic fertilizer is a must for increasing and/or maintaining yields in a sustainable way.

Title : Effect of Different Sources of Organic and Inorganic Nutrients in Wheat under Terai Condition Material Type: printed text Authors: S Devkota, Author ; Shrestha, S., Author ; S.P Vista, Author Pagination: 141-143 p. Languages : English (eng) Keywords: Chemical fertilizer farm yard manure (FYM), poultry and vermicompost. Abstract: An experiment was conducted at RARS, Parwanipur in rice wheat cropping system for two years from 2012 to 2013with nine treatments and four replication with an objective to compare the effect of different sources of organic manure and high analysis chemical fertilizer. Results of the combined analysis revealed that wheat yield and yield attributing parameters such as plant height and panicle length differed significantly with the treatments of the experiment. The highest grain yield (2599 kg ha-1) of wheat was obtained from the plot treated with recommended dose of chemical fertilizer followed by combined application of chemical fertilizer (half of the RDF) and poultry manure @ 10 t ha-1 (2435 kg ha-1). Parameters no. of tillers and test weight were non-significant. Unexpected high yield obtained in combined application of vermicompost, FYM and poultry manure.

Title : Effect of organic matter and iron slime on changes in soil properties Material Type: printed text Authors: S.P Vista, Author Pagination: 178-189 p. Languages : English (eng) Keywords: Better availability, iron-slime, organic matter, physico-chemical properties Abstract: Iron-ore-slime is the waste product of iron and steel industries which has the particle size of below 15mm and is being discarded as waste during the mining and processing stages of iron ore. Laboratory incubation experiment was conducted in the laboratory in 2011 to investigate the effect of organic matter (OM) on soil physico-chemical properties amended with iron- slime with four different treatments replicated four times. Results of characterization study of iron-slime revealed that it is neutral in reaction, contains considerable amount of available plant nutrients and is fairly good enough in its fertility status. Addition of iron-slime influenced soil reaction in maintaining towards neutrality as that of organic matter……………………
